in thirdparty/ffmpeg-x ? Just grep for 'aspect' : grep "aspect" -r thirdparty/ffmpeg/ffmpeg-6.1/libavormat grep "aspect" -r thirdparty/ffmpeg/ffmpeg-6.1/libavcodec grep "aspect" -r thirdparty/ffmpeg/ffmpeg-6.1 -- Cin mailing list [email protected] https://lists.cinelerra-gg.org/mailman/listinfo/cin
