#397(swscale:new): swscale crashes when upscaling pictures using MMX2

#397: swscale crashes when upscaling pictures using MMX2 -------------------------+--------------------- Reporter: TobiX | Owner: michael Type: defect | Status: new Priority: normal | Component: swscale Version: git-master | Keywords: Blocked By: | Blocking: Reproduced: 0 | Analyzed: 0 -------------------------+--------------------- This crash was found using XBMC. XBMC would crash while generating thumbnails for videos which are smaller then the configured thumbnail size. If you want to reproduce this with XBMC, you need to compile it with "--enable-external-libraries" since the internal copy is very old and does not expose this bug. As far as I can see, this crash only happens when upscaling from a YUV to a RGB color space, sample run (make sure video is small then the scale filter options): {{{ $ ./ffmpeg_g -v 9 -loglevel 99 -i in.wmv -sws_flags fast_bilinear -vf "scale=640:480" -vframes 1 -vcodec png output.png ffmpeg version N-31884-gb854c2a, Copyright (c) 2000-2011 the FFmpeg developers built on Aug 14 2011 19:32:25 with gcc 4.6.1 configuration: --disable-doc --disable-stripping libavutil 51. 12. 0 / 51. 12. 0 libavcodec 53. 10. 0 / 53. 10. 0 libavformat 53. 7. 0 / 53. 7. 0 libavdevice 53. 3. 0 / 53. 3. 0 libavfilter 2. 31. 1 / 2. 31. 1 libswscale 2. 0. 0 / 2. 0. 0 [asf @ 0x1fc3420] Format asf probed with size=2048 and score=100 [asf @ 0x1fc3420] gpos mismatch our pos=24, end=26 [asf @ 0x1fc3420] gpos mismatch our pos=24, end=1168 [asf @ 0x1fc3420] gpos mismatch our pos=24, end=38 [asf @ 0x1fc3420] gpos mismatch our pos=24, end=238 [asf @ 0x1fc3420] gpos mismatch our pos=24, end=38 [wmav2 @ 0x1fc58c0] Unsupported bit depth: 0 [wmv2 @ 0x1fc7c20] Unsupported bit depth: 0 [asf @ 0x1fc3420] All info found Seems stream 1 codec frame rate differs from container frame rate: 1000.00 (1000/1) -> 30.00 (30/1) Input #0, asf, from 'in.wmv': Metadata: WMFSDKVersion : 9.00.00.2980 WMFSDKNeeded : 0.0.0.0000 IsVBR : 0 Duration: 00:00:10.23, start: 0.000000, bitrate: 302 kb/s Stream #0.0(eng), 5, 1/1000: Audio: wmav2, 44100 Hz, 1 channels, s16, 32 kb/s Stream #0.1(eng), 41, 1/1000: Video: wmv2, yuv420p, 320x240, 1/1000, 618 kb/s, 30 tbr, 1k tbn, 1k tbc Incompatible pixel format 'yuv420p' for codec 'png', auto-selecting format 'rgb24' [buffer @ 0x1fc5840] w:320 h:240 pixfmt:yuv420p tb:1/1000000 sar:0/1 sws_param: [scale @ 0x1fc7720] w:320 h:240 fmt:yuv420p -> w:640 h:480 fmt:rgb24 flags:0x1 [png @ 0x1fbd740] Unsupported bit depth: 0 [wmv2 @ 0x1fc7c20] Unsupported bit depth: 0 Output #0, image2, to 'output.png': Metadata: WMFSDKVersion : 9.00.00.2980 WMFSDKNeeded : 0.0.0.0000 IsVBR : 0 encoder : Lavf53.7.0 Stream #0.0(eng), 0, 1/90000: Video: png, rgb24, 640x480, 1/30, q=2-31, 200 kb/s, 90k tbn, 30 tbc Stream mapping: Stream #0.1 -> #0.0 Press [q] to stop, [?] for help [wmv2 @ 0x1fc7c20] I7:0/ zsh: segmentation fault ./ffmpeg_g -v 9 -loglevel 99 -i in.wmv -sws_flags fast_bilinear -vf -vframes }}} GDB session: {{{ (gdb) bt #0 0x00000000012894e0 in ??

At the moment, there is no error message, and the drawtext filter doesn't get enabled. The documentation of the drawtext filter does mention then libfreetype is needed - but it would be much more helpful if the configure script would do this check. Otherwise one would have no idea why the filter silently refuses to enable with no error message. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/24> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
