Description
Summary of the bug:
when remux tscc avi to mkv, the mkv can not be displayed
How to reproduce:
% ffmpeg -i xxx.avi -codec copy xxx.mkv % ffplay xxx.mkv libavutil 52. 48.100 / 52. 48.100 libavcodec 55. 39.100 / 55. 39.100 libavformat 55. 19.104 / 55. 19.104 libavdevice 55. 5.100 / 55. 5.100 libavfilter 3. 90.100 / 3. 90.100 libswscale 2. 5.101 / 2. 5.101 libswresample 0. 17.104 / 0. 17.104 libpostproc 52. 3.100 / 52. 3.100 [camtasia @ 0049DD00] Camtasia error: unknown depth 0 bpp0B f=0/0 Last message repeated 1 times Input #0, matroska,webm, from 'xxx.mkv': Metadata: ARTIST : ミサチ德コ。「ツウチヲ ISBJ : Altium Designerヤュタ楨シモ・CBノ COPYRIGHT : オ釋モケ、メオ ENCODER : Lavf55.19.104 Duration: 00:05:39.67, start: 0.000000, bitrate: 690 kb/s Stream #0:0: Video: tscc (tscc / 0x63637374), 1280x772, SAR 1:1 DAR 320:193, 15 fps, 15 tbr, 1k tbn, 1k tbc (default) Stream #0:1: Audio: pcm_s16le, 22050 Hz, 1 channels, s16, 352 kb/s (default) [camtasia @ 0049DD00] Camtasia error: unknown depth 0 bpp 2.43 M-A: 0.000 fd= 0 aq= 11KB vq= 0KB sq= 0B f=0/0
The error message come from
switch(avctx->bits_per_coded_sample){ case 8: avctx->pix_fmt = AV_PIX_FMT_PAL8; break; case 16: avctx->pix_fmt = AV_PIX_FMT_RGB555; break; case 24: avctx->pix_fmt = AV_PIX_FMT_BGR24; break; case 32: avctx->pix_fmt = AV_PIX_FMT_RGB32; break; default: av_log(avctx, AV_LOG_ERROR, "Camtasia error: unknown depth %i bpp\n", avctx->bits_per_coded_sample); return AVERROR_PATCHWELCOME; }
I check the matroskaenc.c and matroskadec.c , mkv muxer does not write the bits_per_coded_sample information for video track , it only write similar information as MATROSKA_ID_AUDIOBITDEPTH for audio track.
avidec.yuv will call ff_get_bmp_header to parse bitmap header to get the bits_per_coded_sample information from video stream.
mkv demuxer also does not do such work. Is it a bug of mkv demuxer or muxer? Is it possible to support RGB Pixel format video stream in mkv container? If possible , what should we do to support such feature?
best regards
