51133a7db0added first version of regression tests - simply type 'make test' to test every codec and some mux/demuxes - added simple synthetic audio and video bitstreams generators so that no big streams needs to be used

a6e14edde0* If a stream gets stuck in WAIT_FEED, then disconnecting the other end will clear out the stream. I think that this is really a linux bug in the handling of poll, but I did a workaround anyway. * Improve the statistics output and prevent a buffer overrun when lots of clients are connected. * Process ffm input when it is received and don't always be one ffm packet behind. * Try to avoid going through the poll loop when not required.

5e57424d11Fix the WAIT_FEED problem. It turns out that when you open up an FFM file and seek to an FFM packet, then it is important that the packet found has a frame header within it. If not, then terrible things happen. This fixes the problem.

79c4ea3c6c* Change the default behaviour to start streaming as soon as possible (i.e. no waiting for key frames). * Provide StartSendOnKey paramter for a stream to wait until we get key frames before sending. * Add the codec names into the status page. May help debugging problems.

9cfe269e70* Updated with new stream configuration items
Philip Gladstone
2002-05-16 02:03:34 +00:00
42a63c6a02* Add code to configure the following: * prebuffering/preroll a live stream -- this improves startup time * videoqmin/videoqmax/videoqdiff -- codec parameters * maximum bandwidth for live streams * Add support for .ram and .rpm extensions mapping onto .rm * Make the status page show bandwidth. Also make the .asf and .rm links go to .asx and .ram files. * Make a stream only start streaming when it gets a keyframe on each stream. This is arguable, and it maybe ought to be restricted to live streams. However, since I don't think that file streams work, this is a step in the right direction. It improves the startup delay. * Log an error if we are unable to delete the temp feed file.

6dc96cb0bf- Now ffmpeg handles MPEG-2 streams with pull down, it gets the real frame rate of the stream.
Juanjo
2002-05-14 22:06:13 +00:00
76c0441b10- Added r_frame_rate in AVStream to store the real frame rate. - This stuff could be done in AVCodecContext and the real frame rate calculated in utils.c, but we don't changes in that by now ;)
Juanjo
2002-05-14 21:50:00 +00:00
e0a3d744a0- repeat_pict meaning changed, now it signals the extra delay for the decoded frame. - extra_delay = (repeat_pict / 2) * (1/fps)

9cd3766f6e- pict_type exported to AVCodecContext - Added real_pict_num to AVCodecContext, it represent the number of the previous encoded frame, usefull when coding with B frames. - Warning fix in motion_est.c

7434ba6d53* Improve logging -- now actually gives you the number of bytes sent * Print out the logging information that comes from WMP (you'd be suprised what it sends! * Fix a remotely exploitable buffer overflow (argh!) * Add support for automatically serving up .asx files. It generates an automatic redirect to the associated .asf file (with the same parameters). I guess that someone who understands the realaudio equivalent could hack that it as well.

1de1cce27d* Make it work with sound cards (like mine) that can only capture in stereo. * Add a kludge to allow the left channel to be inverted -- my tv card/sound card ends up with the left channel = minus right channel. Converting to mono by adding the channels doesn't work well.
Philip Gladstone
2002-05-09 01:15:21 +00:00

f747e6d343* Fix a nasty problem with output buffering not have enough (or large enough) buffers. In fact, the code was pretty much shot. * Try to fool WMP into thinking that we are a microsoft server. * When we establish a stream to a user, copy the codec information from that saved as part of the stream. This gives us the real frame_size and other important parameters. * ASF needs to know about key frames, so add some logic to copy this information around. * When we get the data from ffmpeg as part of a feed, make sure that we save the actual codec parameters. * Allow configuration of AudioCodec and VideoCodec * Make sure that we delete the feed file before starting. This is not ideal but it makes things work a whole lot better!
Philip Gladstone
2002-05-09 01:11:08 +00:00
51bd4565f7* Fix nasty problem with unitialized memory in the file_table * Add default entries to switch statements to catch programming errors * Fix problem with high CPU usage when capturing live (the audio grabber is non-blocking for some reason). This is the stream_no_data stuff. * Handle the video grabber getting behind in its work -- PKT_FLAG_DROPPED_FRAME
