[FFmpeg-devel] [PATCH 4/5] avformat/rawdec: Make the raw packet size configurable
Michael Niedermayer
michael at niedermayer.cc
Sat Jul 6 13:57:48 EEST 2019
This allows testing parsers with a wider range of input packet sizes.
Which is important and usefull for regression testing, some of our
parsers in fact to not work if the packet size is changed from 1024
