From: liushuyu <liush...@aosc.io> In certain mca files, the coefficient table is in the data section instead of the header section. In this case, the coefficient offset relative to the header ending marker is a negative value thus failing the original condition check at line 146.
The new check just check if the coefficient offset is within the file range (since there is no way to know where the actual audio samples are without the correct header information). I have also prepared some sample files for you to test: (Coefficient in data section) https://streams.videolan.org/ffmpeg/incoming/bgm_pot_metal_a1_a_1632.mca And at last, I found some old samples that uses older MCA container format: (MCA Version 3) https://streams.videolan.org/ffmpeg/incoming/s_bgm_4b_DownMix.mca liushuyu (1): avformat: mca: relax a condition check to be able to play certain files libavformat/mca.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) -- 2.28.0 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
