Patching FFmpeg to extract more detailed MV information
13 février 2018, par helmoI am new to video compression and in the past one month I have been studying and reading a lot on this topic. My main aim as of now is to be able to extract in a meaningful way, motion vectors data into a text file.
Some may write about ffmpeg’s extract_mvs.c but I have already explored this example file and is not returning the complete information I would like to get, for instance, the output of this file does not tell the frame type nor whether a backward or forward motion vector was used for a particular frame number.
I saw here on SO a similar post that had as answers to explore ’patch’ of FFMpeg to get more meaningful information, that’s a reply from Ronald.
Is there anyone in the community who can help in expanding this file and get more out of ffmpeg ? Does anyone know about this patch and what it means/entails ?
Thanks in advance.

avcodec/msmpeg4data : Mark tables as hidden
14 octobre 2022, par Andreas Rheinhardtavcodec/msmpeg4data : Mark tables as hidden
This e.g. allows compilers to bake the "+ 256" offset
used to access ff_v2_dc_(lum|chroma)_table into
the general offset ; for certain arches this is also necessary
in order to avoid building suboptimal code.Signed-off-by : Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
