Hello, developers and users of libav!
I'm a bit of user (more tester than serious user) of video editing software
called Cinelerra-GG
This is evolution of original Cinlerrra NLE, and current version uses
ffmpeg/libavcodec 4.2
From manual available at https://cinelerra-gg.org/download/ (see
I included link to our bugtracker issue #330, but it was not meant to say
FFmpeg
should be absolutely blamed on this - just that my primitive fprintf debugging
showed something
like jumping around at seek timestamps (due to cinelerra-GG using different
seek method, relative to ffplay/mplayer)

Hello, all!
I was trying to see if x264's cli option "piulldown" can be ported to
libx264/ffmpeg.
Not as simple as copy/pasta, it seems :O
in x264.c (from x264 source tree) I see this:
/* set up pulldown */
if( opt->i_pulldown && !param->b_vfr_input )
{
param->b_pulldown = 1;

Hello, all!
I was trying to get field order autodetection working in CinelerraGG (our
developer sadly died, so I can't ask him anymore ...)
I get field_order like this:
int FFMPEG::ff_interlace(int stream)
{
/* reads from demuxer because codec frame not ready */
int interlace =
So, I recompiled mplayer (+ffmpeg git at
d43a27ab6fc89b402b5c0d650f0387edf828502b)
just because I bumped libdvdred (5.0.3->6.1.0 -> .so bump :} )
It still plays this stream, but I noticed warning:
mplayer http://animego.ddns.net:1010/anime.aac -cache 900
MPlayer SVN-r38247-10.0.1 (C)
I was trying to simplify some code i do not understand enough (framerate
calculations inside our program (*))
For some reason ffmpeg's mpeg2video encoder only one exporting.
supported_framerates..
And I was thinking it will restrict itself to fps less than 60 (looking at
table)
Yet, it seems

there is ff_ prefixed 'ff_libwebp_error_to_averror' but down the file it
called as just 'libwebp_error_to_averror' and this of course fails to
compile with old enough libwebp (I tried ffmpeg 2.8.17 and libwebp

I disagree with this way of making old hardware even slower.
Guess I can always compile git snapshot or revert those, but aren't changes

I try to build ffmpeg as part of cinelerra-gg videoeditor, and because I
also build inside termux/arm on Android I run into problem at least
starting from ffmpeg-4.4
For some reason B0 defined in system headers and leaks into libavcodec.
I unconditionally undef'ed it in 3 files (see attached

Our software (cinelerra-gg) uses array of pixelformats from libavcodec
encoders for presenting user with menu to choose from
yuv4mpeg encoder does not have this array populated so menu basically
useless ...

Hello!
Our software (cinelerra-gg) had some code for using bitstream filtering at
muxing stage, but it was not functional (crashes)
I tried to use this code as example
https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/tee.c
and added initialization (av_bsf_init())
now simple filters

probably not simplest example, but some branches of Cinelerra (written in
