#824(avcodec:new): Segfault while using h264 hardware acceleration

#824: Segfault while using h264 hardware acceleration -------------------------------------+------------------------------------- Reporter: static-void | Type: defect Status: new | Priority: normal Component: avcodec | Version: git- Keywords: | master Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- I'm using FFmpeg integrated in mplayer (with VA-API pathes), and I'm getting a SIGSEGV while trying to watch h264 video with HW-acceleration. I've poked around with gdb and I think this is multithreading-related. After I added mplayer option "-lavdopts threads=1", which configures libavcodec, the problem has gone. === General info === Crash happens inside a thread, in the start_frame function (libavcodec/vaapi_h264.c:234): {{{ vactx->slice_param_size = sizeof(VASliceParameterBufferH264); ^-- vactx is NULL }}} and vactx is AVCodecContext.hwaccel_context, which should be set to vaapi_context struct instance. But I've set a breakpoint and seen hwaccel_context being properly set at the init stage, although AVCodecContext pointer being not the same as the one in the place it crashes. I suppose it happens because AVCodecContext gets copied and its fields are replicated across worker threads (libavcodec/pthread.c), and I haven't seen hwaccel_context being copied in the code. Considering all above, I don't think it is needed to copy hwaccel_context, but rather to force threads=1 configuration on libavcodec when using HW acceleration. Several working threads would not improve anything in the case of HW accel, would they? === Debug info === {{{ (gdb) run -vo vaapi:gl -va vaapi "<...>.mkv" Starting program: /usr/local/mplayer-vaapi-build/mplayer -vo vaapi:gl -va vaapi "<...>.mkv" [Thread debugging using libthread_db enabled] MPlayer SVN-r34365-4.6.1 (C) 2000-2011 MPlayer Team Playing <...>.mkv. libavformat file format detected.

#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 ??

#24(FFmpeg:new): Error message needed when enabling drawtext filter without libfreetype

#24: Error message needed when enabling drawtext filter without libfreetype -------------------------+------------------------------------------------- Reporter: xj25vm | Owner: michael Type: | Status: new enhancement | Component: FFmpeg Priority: normal | Keywords: configure libfreetype drawtext Version: git | filter Blocked By: | Blocking: Reproduced: 0 | Analyzed: 0 -------------------------+------------------------------------------------- It would be really helpful if the configure script would issue an error message when trying to do "--enable-filter=drawtext" without adding "--enable-libfreetype". 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
