- ┌───────────────────────────────────────────┐
- │ RELEASE NOTES for FFmpeg 2.3 "Mandelbrot" │
- └───────────────────────────────────────────┘
-
-   The FFmpeg Project proudly presents FFmpeg 2.3 "Mandelbrot", a major
-   release with all the great features committed during the three-month period
-   since the release of FFmpeg 2.2.
-
-   In this release, there are lots of internal overhauls that make FFmpeg a
-   more accessible project for new developers. Many important new
-   optimizations and features like QTKit and AVFoundation input devices are
-   committed. Contributions done by Libav such as a new native Opus decoder
-   are also merged.
-
-   Because of the increasing difficulty to maintain and lack of maintainers,
-   we are very sorry to say that we have removed all Blackfin and SPARC
-   architecture assembly optimizations with the cleanups done. If you are
-   interested in maintaining optimization for these two architecture, feel
-   free to contact us and we will restore the code!
-
-   Oh, and since this release, this modern-looking release note is provided in
-   addition to the old-style Changelog file, to make it easier for you to
-   focus on the most important features in this release.
-
-   Enjoy!
-
-   ┌────────────────────────────┐
-   │ *  API Information         │
-   └────────────────────────────┘
-
-     FFmpeg 2.3 is completely source-compatible to the FFmpeg 2.2 series. There
-     are however some API deprecations that you need to take care of. Use `git
-     diff n2.2 n2.3 doc/APIchanges` to show the list of added and deprecated
-     APIs. FFmpeg 2.3 includes the following library versions:
-
-       • libavutil      52.92.100
-       • libavcodec     55.69.100
-       • libavformat    55.48.100
-       • libavdevice    55.13.102
-       • libavfilter     4.11.100
-       • libswscale      2. 6.100
-       • libswresample   0.19.100
-       • libpostproc    52. 3.100
-
-     Please refer to the doc/APIChanges file for more information.
-
-   ┌────────────────────────────┐
-   │ New Optimization           │
-   └────────────────────────────┘
-
-     We are excited to announce that we have committed new x86 assembly
-     optimization for HEVC, and FFmpeg's audio resampler libswresample. ARM
-     users will get a boost in MLP/TrueHD decoding thanks to new optimization.
-     Decoding Huffyuv also got a major boost from optimization on the C code.
-
-     Of special interest for Microsoft Visual Studio users, we have also
-     converted some preexisting x86 assembly to NASM/Yasm format compatible
-     with MSVC setup, especially in the area of audio resampling.
-
-     Another major feature in this release is the introduction of AArch64
-     (ARMv8) assembly optimization. AArch64 is another name for the first
-     64-bit ARM architecture, used by Apple A7 SoC inside iPhone 5S. Some
-     32-bit ARM assembly has already been ported to AArch64, but more work is
-     underway.
-
-   ┌────────────────────────────┐
-   │ Native Opus decoder        │
-   └────────────────────────────┘
-
-     Opus is an open audio format jointly developed by Xiph.Org, Mozilla,
-     Skype/Microsoft, and Broadcom. It combines the features of the Skype Cilk
-     speech codec and the Xiph.Org CELT music codec into one low-latency
-     codec. Decoding Opus is already possible since FFmpeg 1.0 using the
-     libopus library, but the new Opus native decoder brings a higher level of
-     stability and speed.
-
-   ┌────────────────────────────┐
-   │ QTKit and AVFoundation     │
-   └────────────────────────────┘
-
-     For OS X users, the new QTKit and AVFoundation devices allow you to use
-     the integrated camera on Macs. AVFoundation is a newer API only available
-     on OS X 10.7 "Lion" or newer. For users with older OS X systems, the
-     QTKit device using the older OS X API is for you.
-
-   ┌────────────────────────────┐
-   │ API Additions              │
-   └────────────────────────────┘
-
-     In this release, stream side data are introduced as AVStream.side_data as
-     a way to store miscellaneous stream-wide information. The format is
-     similar to the previously anonymous structure AVPacket.side_data (now
-     named as AVPacketSideData). With this change, audio ReplayGain
-     information and video rotation matrix are now exported through this API,
-     if available in the demuxer.
-
-     We also have improved libswresample's Doxygen API documentation, so new
-     developers wishing to use FFmpeg's excellent libraries can get started
-     more easily and faster.
-
-   ┌────────────────────────────┐
-   │ Last But Not Least         │
-   └────────────────────────────┘
-
-     Other interesting new features including hqx video filter, a pixel art
-     scaling filter; a fixed-point AC-3 decoder contributed by Imagination
-     Technologies; an On2 TrueMotion VP7 video decoder; an HTML5 WebVTT
-     subtitle encoder that allows creation of WebVTT from any text-based
-     subtitles; and an 1-bit Direct Stream Digital audio decoder.

-
-Win32 GDI-based screen capture device.
-
-This device allows you to capture a region of the display on Windows.
-
-There are two options for the input filename:
-@example
-desktop
-@end example
-or
-@example
-title=@var{window_title}
-@end example
-
-The first option will capture the entire desktop, or a fixed region of the
-desktop. The second option will instead capture the contents of a single
-window, regardless of its position on the screen.
-
-For example, to grab the entire desktop using @command{ffmpeg}:
-@example
-ffmpeg -f gdigrab -framerate 6 -i desktop out.mpg
-@end example
-
-Grab a 640x480 region at position @code{10,20}:
-@example
-ffmpeg -f gdigrab -framerate 6 -offset_x 10 -offset_y 20 -video_size vga -i desktop out.mpg
-@end example
-
-Grab the contents of the window named "Calculator"
-@example
-ffmpeg -f gdigrab -framerate 6 -i title=Calculator out.mpg
-@end example
-
-@subsection Options
-
-@table @option
-@item draw_mouse
-Specify whether to draw the mouse pointer. Use the value @code{0} to
-not draw the pointer. Default value is @code{1}.
-
-@item framerate
-Set the grabbing frame rate. Default value is @code{ntsc},
-corresponding to a frame rate of @code{30000/1001}.
-
-@item show_region
-Show grabbed region on screen.
-
-If @var{show_region} is specified with @code{1}, then the grabbing
-region will be indicated on screen. With this option, it is easy to
-know what is being grabbed if only a portion of the screen is grabbed.
-
-Note that @var{show_region} is incompatible with grabbing the contents
-of a single window.

-
-@item offset_x
-When capturing a region with @var{video_size}, set the distance from the left edge of the screen or desktop.
-
-Note that the offset calculation is from the top left corner of the primary monitor on Windows. If you have a monitor positioned to the left of your primary monitor, you will need to use a negative @var{offset_x} value to move the region to that monitor.

-This document is a tutorial/initiation for writing simple filters in
-libavfilter.
-
-Foreword: just like everything else in FFmpeg, libavfilter is monolithic, which
-means that it is highly recommended that you submit your filters to the FFmpeg
-development mailing-list and make sure it is applied. Otherwise, your filter is
-likely to have a very short lifetime due to more a less regular internal API
-changes, and a limited distribution, review, and testing.
-
-Bootstrap
-=========
-
-Let's say you want to write a new simple video filter called "foobar" which
-takes one frame in input, changes the pixels in whatever fashion you fancy, and
-outputs the modified frame. The most simple way of doing this is to take a
-similar filter.  We'll pick edgedetect, but any other should do. You can look
-for others using the `./ffmpeg -v 0 -filters|grep ' V->V '` command.
-
- - cp libavfilter/vf_{edgedetect,foobar}.c
- - sed -i s/edgedetect/foobar/g -i libavfilter/vf_foobar.c
- - sed -i s/EdgeDetect/Foobar/g -i libavfilter/vf_foobar.c
- - edit libavfilter/Makefile, and add an entry for "foobar" following the
-   pattern of the other filters.
- - edit libavfilter/allfilters.c, and add an entry for "foobar" following the
-   pattern of the other filters.
- - ./configure ...
- - make -j<whatever> ffmpeg
- - ./ffmpeg -i tests/lena.pnm -vf foobar foobar.png
-
-If everything went right, you should get a foobar.png with Lena edge-detected.
-
-That's it, your new playground is ready.
-
-Some little details about what's going on:
-libavfilter/allfilters.c:avfilter_register_all() is called at runtime to create
-a list of the available filters, but it's important to know that this file is
-also parsed by the configure script, which in turn will define variables for
-the build system and the C:
-
-    --- after running configure ---
-
-    $ grep FOOBAR config.mak
-    CONFIG_FOOBAR_FILTER=yes
-    $ grep FOOBAR config.h
-    #define CONFIG_FOOBAR_FILTER 1
-
-CONFIG_FOOBAR_FILTER=yes from the config.mak is later used to enable the filter in
-libavfilter/Makefile and CONFIG_FOOBAR_FILTER=1 from the config.h will be used
-for registering the filter in libavfilter/allfilters.c.
-
-Filter code layout
-==================
-
-You now need some theory about the general code layout of a filter. Open your
-libavfilter/vf_foobar.c. This section will detail the important parts of the
-code you need to understand before messing with it.
-
-Copyright
---------
-
-First chunk is the copyright. Most filters are LGPL, and we are assuming
-vf_foobar is as well. We are also assuming vf_foobar is not an edge detector
-filter, so you can update the boilerplate with your credits.
-
-Doxy
----
-
-Next chunk is the Doxygen about the file. See http://ffmpeg.org/doxygen/trunk/.
-Detail here what the filter is, does, and add some references if you feel like
-it.
-
-Context
-------
-
-Skip the headers and scroll down to the definition of FoobarContext. This is
-your local state context. It is already filled with 0 when you get it so do not
-worry about uninitialized read into this context. This is where you put every
-"global" information you need, typically the variable storing the user options.
-You'll notice the first field "const AVClass *class"; it's the only field you
-need to keep assuming you have a context. There are some magic you don't care
-about around this field, just let it be (in first position) for now.
-
-Options
-------
-
-Then comes the options array. This is what will define the user accessible
-options. For example, -vf foobar=mode=colormix:high=0.4:low=0.1. Most options
-have the following pattern:
-  name, description, offset, type, default value, minimum value, maximum value, flags
-
- - name is the option name, keep it simple, lowercase
- - description are short, in lowercase, without period, and describe what they
-   do, for example "set the foo of the bar"
- - offset is the offset of the field in your local context, see the OFFSET()
-   macro; the option parser will use that information to fill the fields
-   according to the user input
- - type is any of AV_OPT_TYPE_* defined in libavutil/opt.h
- - default value is an union where you pick the appropriate type; "{.dbl=0.3}",
-   "{.i64=0x234}", "{.str=NULL}", ...
- - min and max values define the range of available values, inclusive
- - flags are AVOption generic flags. See AV_OPT_FLAG_* definitions
-
-In doubt, just look at the other AVOption definitions all around the codebase,
-there are tons of examples.
-
-Class
-----
-
-AVFILTER_DEFINE_CLASS(foobar) will define a unique foobar_class with some kind
-of signature referencing the options, etc. which will be referenced in the
-definition of the AVFilter.
-
-Filter definition
-----------------
-
-At the end of the file, you will find foobar_inputs, foobar_outputs and
-the AVFilter ff_vf_foobar. Don't forget to update the AVFilter.description with
-a description of what the filter does, starting with a capitalized letter and
-ending with a period. You'd better drop the AVFilter.flags entry for now, and
-re-add them later depending on the capabilities of your filter.
-
-Callbacks
---------
-
-Let's now study the common callbacks. Before going into details, note that all
-these callbacks are explained in details in libavfilter/avfilter.h, so in
-doubt, refer to the doxy in that file.
-
-init()
-~~~~~~
-
-First one to be called is init(). It's flagged as cold because not called
-often. Look for "cold" on
-http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html for more
-information.
-
-As the name suggests, init() is where you eventually initialize and allocate
-your buffers, pre-compute your data, etc. Note that at this point, your local
-context already has the user options initialized, but you still haven't any
-clue about the kind of data input you will get, so this function is often
-mainly used to sanitize the user options.
-
-Some init()s will also define the number of inputs or outputs dynamically
-according to the user options. A good example of this is the split filter, but
-we won't cover this here since vf_foobar is just a simple 1:1 filter.
-
-uninit()
-~~~~~~~~
-
-Similarly, there is the uninit() callback, doing what the name suggest. Free
-everything you allocated here.
-
-query_formats()
-~~~~~~~~~~~~~~~
-
-This is following the init() and is used for the format negotiation, basically
-where you say what pixel format(s) (gray, rgb 32, yuv 4:2:0, ...) you accept
-for your inputs, and what you can output. All pixel formats are defined in
-libavutil/pixfmt.h. If you don't change the pixel format between the input and
-the output, you just have to define a pixel formats array and call
-ff_set_common_formats(). For more complex negotiation, you can refer to other
-filters such as vf_scale.
-
-config_props()
-~~~~~~~~~~~~~~
-
-This callback is not necessary, but you will probably have one or more
-config_props() anyway. It's not a callback for the filter itself but for its
-inputs or outputs (they're called "pads" - AVFilterPad - in libavfilter's
-lexicon).
-
-Inside the input config_props(), you are at a point where you know which pixel
-format has been picked after query_formats(), and more information such as the
-video width and height (inlink->{w,h}). So if you need to update your internal
-context state depending on your input you can do it here. In edgedetect you can
-see that this callback is used to allocate buffers depending on these
-information. They will be destroyed in uninit().
-
-Inside the output config_props(), you can define what you want to change in the
-output. Typically, if your filter is going to double the size of the video, you
-will update outlink->w and outlink->h.
-
-filter_frame()
-~~~~~~~~~~~~~~
-
-This is the callback you are waiting from the beginning: it is where you
-process the received frames. Along with the frame, you get the input link from
-where the frame comes from.
-
-    static int filter_frame(AVFilterLink *inlink, AVFrame *in) { ... }
-
-You can get the filter context through that input link:
-
-    AVFilterContext *ctx = inlink->dst;
-
-Then access your internal state context:
-
-    FoobarContext *foobar = ctx->priv;
-
-And also the output link where you will send your frame when you are done:
-
-    AVFilterLink *outlink = ctx->outputs[0];
-
-Here, we are picking the first output. You can have several, but in our case we
-only have one since we are in a 1:1 input-output situation.
-
-If you want to define a simple pass-through filter, you can just do:
-
-    return ff_filter_frame(outlink, in);
-
-But of course, you probably want to change the data of that frame.
-
-This can be done by accessing frame->data[] and frame->linesize[].  Important
-note here: the width does NOT match the linesize. The linesize is always
-greater or equal to the width. The padding created should not be changed or
-even read. Typically, keep in mind that a previous filter in your chain might
-have altered the frame dimension but not the linesize. Imagine a crop filter
-that halves the video size: the linesizes won't be changed, just the width.
-
-    <-------------- linesize ------------------------>

-    +-------------------------------+----------------+ v
-    <----------- width ------------->
-
-Before modifying the "in" frame, you have to make sure it is writable, or get a
-new one. Multiple scenarios are possible here depending on the kind of
-processing you are doing.
-
-Let's say you want to change one pixel depending on multiple pixels (typically
-the surrounding ones) of the input. In that case, you can't do an in-place
-processing of the input so you will need to allocate a new frame, with the same
-properties as the input one, and send that new frame to the next filter:
-
-    AVFrame *out = ff_get_video_buffer(outlink, outlink->w, outlink->h);
-    if (!out) {
-        av_frame_free(&in);
-        return AVERROR(ENOMEM);
-    }
-    av_frame_copy_props(out, in);
-
-    // out->data[...] = foobar(in->data[...])
-
-    av_frame_free(&in);
-    return ff_filter_frame(outlink, out);
-
-In-place processing
-~~~~~~~~~~~~~~~~~~~
-
-If you can just alter the input frame, you probably just want to do that
-instead:
-
-    av_frame_make_writable(in);
-    // in->data[...] = foobar(in->data[...])
-    return ff_filter_frame(outlink, in);
-
-You may wonder why a frame might not be writable. The answer is that for
-example a previous filter might still own the frame data: imagine a filter
-prior to yours in the filtergraph that needs to cache the frame. You must not
-alter that frame, otherwise it will make that previous filter buggy. This is
-where av_frame_make_writable() helps (it won't have any effect if the frame
-already is writable).
-
-The problem with using av_frame_make_writable() is that in the worst case it
-will copy the whole input frame before you change it all over again with your
-filter: if the frame is not writable, av_frame_make_writable() will allocate
-new buffers, and copy the input frame data. You don't want that, and you can
-avoid it by just allocating a new buffer if necessary, and process from in to
-out in your filter, saving the memcpy. Generally, this is done following this
-scheme:
-
-    int direct = 0;
-    AVFrame *out;
-
-    if (av_frame_is_writable(in)) {
-        direct = 1;
-        out = in;
-    } else {
-        out = ff_get_video_buffer(outlink, outlink->w, outlink->h);
-        if (!out) {
-            av_frame_free(&in);
-            return AVERROR(ENOMEM);
-        }
-        av_frame_copy_props(out, in);
-    }
-
-    // out->data[...] = foobar(in->data[...])
-
-    if (!direct)
-        av_frame_free(&in);
-    return ff_filter_frame(outlink, out);
-
-Of course, this will only work if you can do in-place processing. To test if
-your filter handles well the permissions, you can use the perms filter. For
-example with:
-
-    -vf perms=random,foobar
-
-Make sure no automatic pixel conversion is inserted between perms and foobar,
-otherwise the frames permissions might change again and the test will be
-meaningless: add av_log(0,0,"direct=%d\n",direct) in your code to check that.
-You can avoid the issue with something like:
-
-    -vf format=rgb24,perms=random,foobar
-
-...assuming your filter accepts rgb24 of course. This will make sure the
-necessary conversion is inserted before the perms filter.
-
-Timeline
-~~~~~~~~
-
-Adding timeline support
-(http://ffmpeg.org/ffmpeg-filters.html#Timeline-editing) is often an easy
-feature to add. In the most simple case, you just have to add
-AVFILTER_FLAG_SUPPORT_TIMELINE_GENERIC to the AVFilter.flags. You can typically
-do this when your filter does not need to save the previous context frames, or
-basically if your filter just alter whatever goes in and doesn't need
-previous/future information. See for instance commit 86cb986ce that adds
-timeline support to the fieldorder filter.
-
-In some cases, you might need to reset your context somehow. This is handled by
-the AVFILTER_FLAG_SUPPORT_TIMELINE_INTERNAL flag which is used if the filter
-must not process the frames but still wants to keep track of the frames going
-through (to keep them in cache for when it's enabled again). See for example
-commit 69d72140a that adds timeline support to the phase filter.
-
-Threading
-~~~~~~~~~
-
-libavfilter does not yet support frame threading, but you can add slice
-threading to your filters.
-
-Let's say the foobar filter has the following frame processing function:
-
-    dst = out->data[0];
-    src = in ->data[0];
-
-    for (y = 0; y < inlink->h; y++) {
-        for (x = 0; x < inlink->w; x++)
-            dst[x] = foobar(src[x]);
-        dst += out->linesize[0];
-        src += in ->linesize[0];
-    }
-
-The first thing is to make this function work into slices. The new code will
-look like this:
-
-    for (y = slice_start; y < slice_end; y++) {
-        for (x = 0; x < inlink->w; x++)
-            dst[x] = foobar(src[x]);
-        dst += out->linesize[0];
-        src += in ->linesize[0];
-    }
-
-The source and destination pointers, and slice_start/slice_end will be defined
-according to the number of jobs. Generally, it looks like this:
-
-    const int slice_start = (in->height *  jobnr   ) / nb_jobs;
-    const int slice_end   = (in->height * (jobnr+1)) / nb_jobs;
-    uint8_t       *dst = out->data[0] + slice_start * out->linesize[0];
-    const uint8_t *src =  in->data[0] + slice_start *  in->linesize[0];
-
-This new code will be isolated in a new filter_slice():
-
-    static int filter_slice(AVFilterContext *ctx, void *arg, int jobnr, int nb_jobs) { ... }
-
-Note that we need our input and output frame to define slice_{start,end} and
-dst/src, which are not available in that callback. They will be transmitted
-through the opaque void *arg. You have to define a structure which contains
-everything you need:
-
-    typedef struct ThreadData {
-        AVFrame *in, *out;
-    } ThreadData;
-
-If you need some more information from your local context, put them here.
-
-In you filter_slice function, you access it like that:
-
-    const ThreadData *td = arg;
-
-Then in your filter_frame() callback, you need to call the threading
-distributor with something like this:
-
-    ThreadData td;
-
-    // ...
-
-    td.in  = in;
-    td.out = out;
-    ctx->internal->execute(ctx, filter_slice, &td, NULL, FFMIN(outlink->h, ctx->graph->nb_threads));
-
-    // ...
-
-    return ff_filter_frame(outlink, out);
-
-Last step is to add AVFILTER_FLAG_SLICE_THREADS flag to AVFilter.flags.
-
-For more example of slice threading additions, you can try to run git log -p
--grep 'slice threading' libavfilter/
-
-Finalization
-~~~~~~~~~~~~
-
-When your awesome filter is finished, you have a few more steps before you're
-done:
-
- - write its documentation in doc/filters.texi, and test the output with make
-   doc/ffmpeg-filters.html.
- - add a FATE test, generally by adding an entry in
-   tests/fate/filter-video.mak, add running make fate-filter-foobar GEN=1 to
-   generate the data.
- - add an entry in the Changelog
- - edit libavfilter/version.h and increase LIBAVFILTER_VERSION_MINOR by one
-   (and reset LIBAVFILTER_VERSION_MICRO to 100)
- - git add ... && git commit -m "avfilter: add foobar filter." && git format-patch -1
-
-When all of this is done, you can submit your patch to the ffmpeg-devel
-mailing-list for review.  If you need any help, feel free to come on our IRC
-channel, #ffmpeg-devel on irc.freenode.net.
