#9: libswscale MMX2 giving videos a pink lined overlay ----------------------+---------------------- Reporter: bizzehdee | Owner: michael Type: defect | Status: new Priority: normal | Component: swscale Version: git | Resolution: Keywords: | Blocked By: Blocking: | Reproduced: 0 Analyzed: 0 | ----------------------+---------------------- Comment (by cehoyos): Does the original file make any difference? I just tested the following on an Athlon XP with a random video that I encoded to mpeg4 (496x384) and the result looks ok: {{{ ffmpeg -i input -target pal-dvd -sws_flags bilinear+3dnow test.mpg }}} Is -target pal-dvd needed or is "-s 720x576" sufficient to trigger the problem? Is the problem also reproducible if you add -an to the command line? -- Ticket URL: <https://avcodec.org/trac/ffmpeg/ticket/9#comment:19> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#32: too long time waste on the part before intended snippet and encode zero frame when encode a rmvb file to an avi snippet ------------------------+--------------------- Reporter: littlebat | Owner: michael Type: defect | Status: new Priority: normal | Component: FFmpeg Version: git | Keywords: Blocked By: | Blocking: Reproduced: 1 | Analyzed: 0 ------------------------+--------------------- I tried to get an avi snippet from a rmvb movie using ffmpeg, this is my command line: ffmpeg -i yyzs.rmvb -ss 02:40:00 -t 00:10:00 yyzs17.avi But, it spend about 10 minutes on the part before intended snippet and encode zero frame, the last 1 minutes it worked on that snippet. The key message is: "Buffering several frames is not supported. Please consume all available frames before adding a new one." I tried encoding rmvb to avi, rmvb to mp4, mp4 to mp4, mp4 to avi, got the same result. ffmpeg compiled from newest git repository: FFmpeg version git-N-28755-g7ac1674 Envirnment: Vmware virtual machine(Core(TM)2 Duo CPU E7400), Ubuntu 10.04 Console output: (break the long time running and omitted some repeat messages): mdx@u1004b2-desktop:/media/1217e/mdx/share/rwshare/yyzs$ ffmpeg -i yyzs.rmvb -ss 02:40:00 -t 00:10:00 yyzs17.ffmpeg.refresh.avi FFmpeg version git-N-28755-g7ac1674, Copyright (c) 2000-2011 the FFmpeg developers built on Apr 1 2011 15:36:56 with gcc 4.4.3 configuration: libavutil 50. 40. 0 / 50. 40. 0 libavcodec 52.116. 0 / 52.116. 0 libavformat 52.104. 0 / 52.104. 0 libavdevice 52. 4. 0 / 52. 4. 0 libavfilter 1. 76. 0 / 1. 76. 0 libswscale 0. 13. 0 / 0. 13. 0 [NULL @ 0xa9f3010] Unsupported video codec [rm @ 0xa9ea600] max_analyze_duration reached Input #0, rm, from 'yyzs.rmvb': Metadata: title : author : copyright : comment : Duration: 02:45:12.13, start: 0.000000, bitrate: 608 kb/s Stream #0.0: Video: rv40, yuv420p, 640x360, 531 kb/s, 12.05 fps, 12 tbr, 1k tbn, 12 tbc Stream #0.1: Audio: cook, 44100 Hz, stereo, s16, 64 kb/s Stream #0.2: Data: [0][0][0][0] / 0x0000 [buffer @ 0xaa76500] w:640 h:360 pixfmt:yuv420p Output #0, avi, to 'yyzs17.ffmpeg.refresh.avi': Metadata: INAM : author : ICOP : ICMT : ISFT : Lavf52.104.0 Stream #0.0: Video: mpeg4, yuv420p, 640x360, q=2-31, 200 kb/s, 12 tbn, 12 tbc Stream #0.1: Audio: mp2, 44100 Hz, stereo, s16, 64 kb/s Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 Press [q] to stop encoding [buffer @ 0xaa76500] Buffering several frames is not supported.
