Dear all,
When VideoLAN-VLC converts an H.265/HEVC-encoded file in AVI format, by executing a command such as: VLC -I dummy Tears_400_x265.mp4 --sout=#{access=file,mux=avi,dst='Tears_400_x265.avi'} vlc://quit VLC and Media Player Classic Home Cinema are able to read and play the resulting AVI file. When I try to do the same with ffmpeg, running a command such as: ffmpeg -i Tears_400_x265.mp4 -vcodec copy -f avi Tears_400_x265.avi VLC is not able to read the result, because ffmpeg writes hvc1 at offset 188 (= BITMAPINFOHEADER.biCompression), instead of hevc as expected by VLC and MPC-HC. Incidentally, I notice that fmpeg also writes hvc1 at offset 112 (= fccHandler) instead of cveh as VLC does. When I try to do the same with a raw H.265 file, ffmpeg writes 00:00:00:00 (null bytes) in fields fccHandler and BITMAPINFOHEADER.biCompression, instead of cveh and hevc as expected by VLC, although the trace shows that ffmpeg actually detects the HEVC codec: Stream #0:0: Video: hevc, 1 reference frame, yuv420p(tv), 1280x720, 25 fps, 25 tbr, 1200k tbn, 25 tbc Would it be possible for ffmpeg, when it converts an H.265/HEVC-encoded file to AVI, to write cveh (0x63 0x76 0x65 0x68) at offset 112 (= fccHandler) and hevc (0x68 0x65 0x76 0x63) at offset 188 (=BITMAPINFOHEADER.biCompression), so that VLC and MPC-HC can play the file? Best regards, Gregoire P,S, H.265-encoded video clip https://s3.amazonaws.com/x265.org/video/Tears_400_x265.mp4 can be downloaded from https://x265.com/hevc-video-files/ web site. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
