2e5a9e580c examples/encoding.c: use av_image_alloc() for allocating an image buffer
Simplify.

2420763638 graphparser: simplify condition in avfilter_graph_parse()
Since avfilter_graph_parse() creates the "[in]" inout for the first
unlabelled input pad, it is expected that it will create an "[out]"
inout for last unlabelled output pad, even in the case where it cannot
find any open input pad with that name.

This change removes the check on the existence of an open input pad
named "out", so it simplifies the checked condition while implementing
a more intuitive behavior.

e35c674d13 alsa: limit buffer_size to 32768 frames.
In testing, the file output plugin gave a max buffer size of about 20 million
frames, which is way more than what is really needed and causes a memory
allocation error on my system.

8bfd7f6a47 alsa: fallback to buffer_size/4 for period_size.
buffer_size/4 is the value used by aplay. This fixes output to null
devices, e.g. writing ALSA output to a file.

a7d3a51dd1 cosmetic: reindent of dxva2 zigzag workaround 2011-07-09 17:30:25 +02:00
Joakim Plate
6dabe0f74a Added ability to enable workaround for dxva2 decoding using older ATI cards
The workaround need to be enabled per pci id which can not
be detected inside ffmpeg. So this adds a flag that enabled
the alternate behavior.

99fecc64b0 gxf: Fix 25 fps DV material in GXF being misdetected as 50 fps
Set DV packet durations using fields_per_frame.
This requires turning gxf_stream_info into the demuxer's context for access to the value in gxf_packet().
Since MPEG-2 seems to work fine this done only for DV.

7d7bacf0f1 swscale: fix overflow in 16-bit vertical scaling.
We operated on 31-bits, but with e.g. lanczos scaling, values can
add up to beyond 0x80000000, thus leading to output of zeroes. Drop
one bit of precision fixes this.
