#2153: aac 7.1 channel layout -------------------------------------+------------------------------------- Reporter: Crayden | Type: defect Status: new | Priority: normal Component: avcodec | Version: Keywords: 7.1 aac | unspecified channel layout | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Looking at the specification from http://developer.apple.com/library/mac/#documentation/MusicAudio/Reference/… the channels are decoded correctly for 7.1 aac files but it looks like they're mapped/mixed in the wrong way resulting in the following output behaviour: left -> left + center center -> center right -> right + center right surround -> right left surround -> left right rear surround -> right rear surround left rear surround -> left rear surround lfe -> lfe Since most players and audio drivers don't handle this specific layout correctly it may be wise to convert the layout for 7.1 channel aac files to a standard layout. This issue has already been fixed in the ffmpeg fork for LAV-Filter. Take a look at: http://git.1f0.de/gitweb?p=ffmpeg.git;a=commit;h=dfcbfd57c35bbef83df5c52564… If you need a test file: https://www.dropbox.com/s/csnm34xap2176sv/Channel%20Check%20Lots%20of%20For… (make sure to select the 7.1 channel aac track) -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/2153> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#1582(avfilter:new): Banding/discoloration in darker gradients when converting to rgb24

#1582: Banding/discoloration in darker gradients when converting to rgb24 ----------------------------------+--------------------------------------- Reporter: y3kcjd5 | Type: defect Status: new | Priority: normal Component: avfilter | Version: unspecified Keywords: win64 | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+--------------------------------------- Summary: I've discovered that when I'm converting videos to the rgb24 format (in attempting to use the libx264rgb codec) I get banding and discoloration in darker areas with (color) gradients. To eliminate the possibility that it was the codec (as opposed to the format filter) causing the problem, I did some tests converting the video to .png images. Specifically, I found that: yuv420p10le(source video) -- looks nice yuv420p10le -> rgb24 -- banding/discoloration yuv420p10le -> rgb48be -- looks nice yuv420p10le -> rgb48be -> rgb24 -- banding/discoloration yuv420p10le -> yuv420p -> rgb24 -- banding but no discoloration I assume that the banding in the yuv420p example is simply a result of the reduced colorspace, but I don't see why any of the other conversions should result in any visible changes. I'm using one of Zeranoe's windows builds (win7 64bit) so I don't know if this happens on Linux. Log file output for the yuv420p10le->rgb24 example follows: {{{ ffmpeg started on 2012-07-28 at 10:56:16 Report written to "ffmpeg-20120728-105616.log" Command line: ffmpeg -i vtst0.mp4 -map 0:0 -vsync 0 -report -filter:v "format=rgb24" "tst%03d.png" ffmpeg version N-42704-g85761ef Copyright (c) 2000-2012 the FFmpeg developers built on Jul 20 2012 20:39:19 with gcc 4.7.1 (GCC) configuration: --enable-gpl --enable-version3 --disable-w32threads --enable-runtime-cpudetect --enable-avisynth --enable-bzlib --enable- frei0r --enable-libass --enable-libcelt --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libfreetype --enable-libgsm --enable- libmp3lame --enable-libnut --enable-libopenjpeg --enable-librtmp --enable- libschroedinger --enable-libspeex --enable-libtheora --enable-libutvideo --enable-libvo-aacenc --enable-libvo-amrwbenc --enable-libvorbis --enable- libvpx --enable-libx264 --enable-libxavs --enable-libxvid --enable-zlib libavutil 51. 65.100 / 51. 65.100 libavcodec 54. 42.100 / 54. 42.100 libavformat 54. 18.100 / 54. 18.100 libavdevice 54. 1.100 / 54. 1.100 libavfilter 3. 2.100 / 3. 2.100 libswscale 2. 1.100 / 2. 1.100 libswresample 0. 15.100 / 0. 15.100 libpostproc 52. 0.100 / 52. 0.100 [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000002e2ec0] Format mov,mp4,m4a,3gp,3g2,mj2 probed with size=2048 and score=100 [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000002e2ec0] ISO: File Type Major Brand: isom [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000002e2ec0] File position before avformat_find_stream_info() is 7074306 [h264 @ 00000000002f40a0] no picture [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000002e2ec0] All info found rfps: 23.750000 0.011875 rfps: 23.833333 0.004757 rfps: 23.916667 0.000859 rfps: 24.000000 0.000180 rfps: 24.083333 0.002721 rfps: 24.166667 0.008482 rfps: 24.250000 0.017461 rfps: 47.666667 0.019029 rfps: 47.750000 0.009623 rfps: 47.833333 0.003436 rfps: 47.916667 0.000469 rfps: 48.000000 0.000722 rfps: 48.083333 0.004194 rfps: 48.166667 0.010885 rfps: 23.976024 0.000046 rfps: 47.952048 0.000183 [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000002e2ec0] File position after avformat_find_stream_info() is 1243950 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'vtst0.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf54.18.100 Duration: 00:00:10.09, start: 0.000000, bitrate: 5607 kb/s Stream #0:0(und), 41, 1/1000: Video: h264 (High 10) (avc1 / 0x31637661), yuv420p10le, 1920x1080, 5604 kb/s, 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc Metadata: handler_name : VideoHandler [buffer @ 0000000004ba0f20] Setting entry with key 'video_size' to value '1920x1080' [buffer @ 0000000004ba0f20] Setting entry with key 'pix_fmt' to value '72' [buffer @ 0000000004ba0f20] Setting entry with key 'time_base' to value '1/1000' [buffer @ 0000000004ba0f20] Setting entry with key 'pixel_aspect' to value '0/1' [buffer @ 0000000004ba0f20] Setting entry with key 'sws_param' to value 'flags=2' [buffer @ 0000000004ba0f20] Setting entry with key 'frame_rate' to value '24000/1001' [graph 0 input from stream 0:0 @ 0000000004d73980] w:1920 h:1080 pixfmt:yuv420p10le tb:1/1000 fr:24000/1001 sar:0/1 sws_param:flags=2 [Parsed_format_0 @ 0000000004d738e0] auto-inserting filter 'auto-inserted scaler 0' between the filter 'graph 0 input from stream 0:0' and the filter 'Parsed_format_0' [auto-inserted scaler 0 @ 0000000004d73b20] w:1920 h:1080 fmt:yuv420p10le sar:0/1 -> w:1920 h:1080 fmt:rgb24 sar:0/1 flags:0x4 [h264 @ 00000000002f40a0] detected 2 logical cores Output #0, image2, to 'tst%03d.png': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf54.18.100 Stream #0:0(und), 0, 1/90000: Video: png, rgb24, 1920x1080, q=2-31, 200 kb/s, 90k tbn, 23.98 tbc Metadata: handler_name : VideoHandler Stream mapping: Stream #0:0 -> #0:0 (h264 -> png) Press [q] to stop, [?] for help [h264 @ 00000000003aa100] no picture DTS -42, next:-62146 st:0 invalid dropping [h264 @ 0000000004cdbf00] no picture frame= 3 fps=0.0 q=0.0 size= 0kB time=00:00:00.12 bitrate= 0.0kbits/s frame= 5 fps=3.1 q=0.0 size= 0kB time=00:00:00.20 bitrate= 0.0kbits/s frame= 7 fps=3.0 q=0.0 size= 0kB time=00:00:00.29 bitrate= 0.0kbits/s ... frame= 237 fps=2.6 q=0.0 size= 0kB time=00:00:09.88 bitrate= 0.0kbits/s No more inputs to read from, finishing.

#314: OpenAL device does not work on OS X ----------------------+-------------------------- Reporter: nieder | Type: enhancement Status: new | Priority: normal Component: avdevice | Version: git-master Keywords: | Blocked By: Blocking: | Reproduced: 0 Analyzed: 0 | ----------------------+-------------------------- configure is not set to find openal on OS X. The fix for the linker check is easy: add "-Wl,-framework,OpenAL" to the list of flags to check {{{ -enabled openal && { { for al_libs in "${OPENAL_LIBS}" "-lopenal" "-lOpenAL32"; do +enabled openal && { { for al_libs in "${OPENAL_LIBS}" "-lopenal" "-lOpenAL32" "-Wl,-framework,OpenAL"; do }}} I don't know how to fix the header check to look for multiple possibilities, but on OS X the header in the OpenAL framework is found in OpenAL/al.h (not AL/al.h like in linux). If I change the header check in configure and the includes in libavdevice/openal-dec.c, the build and linkage works well. However, running 'ffmpeg -f openal' as suggested in the manual fails with an malloc error, so this might just not be doable on OS X. {{{ nieder $ /usr/local/ffmpeg-git/bin/ffmpeg -list_devices true -f openal -i dummy out.ogg ffmpeg version N-31036-g65eae2a, Copyright (c) 2000-2011 the FFmpeg developers built on Jun 27 2011 10:29:19 with gcc 4.0.1 (Apple Inc. build 5493) configuration: --prefix=/usr/local/ffmpeg-git --mandir=/usr/local /ffmpeg-git/share/man --disable-static --enable-shared --enable-gpl --enable-version3 --enable-postproc --enable-pthreads --enable-x11grab --enable-bzlib --enable-libcelt --enable-libopencore-amrnb --enable- libopencore-amrwb --enable-libdirac --enable-libfreetype --enable- libmp3lame --enable-libopenjpeg --enable-librtmp --enable-libschroedinger --enable-libspeex --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --enable-openal --enable-zlib --disable- debug --extra-cflags='-I/sw/lib/libspeex1/include -I/sw/include -I/usr/X11R6/include' --extra-ldflags='-L/sw/lib/libspeex1/lib -L/sw/lib -L/usr/X11R6/lib' libavutil 51. 10. 0 / 51. 10. 0 libavcodec 53. 7. 0 / 53. 7. 0 libavformat 53. 4. 0 / 53. 4. 0 libavdevice 53. 2. 0 / 53. 2. 0 libavfilter 2. 24. 0 / 2. 24. 0 libswscale 2. 0. 0 / 2. 0. 0 libpostproc 51. 2. 0 / 51. 2. 0 [openal @ 0x200a800] List of OpenAL capture devices on this system: [openal @ 0x200a800] Built-in Microphone dummy: Immediate exit requested nieder $ /usr/local/ffmpeg-git/bin/ffmpeg -f openal -i 'Built-in Microphone' out.ogg ffmpeg version N-31036-g65eae2a, Copyright (c) 2000-2011 the FFmpeg developers built on Jun 27 2011 10:29:19 with gcc 4.0.1 (Apple Inc. build 5493) configuration: --prefix=/usr/local/ffmpeg-git --mandir=/usr/local /ffmpeg-git/share/man --disable-static --enable-shared --enable-gpl --enable-version3 --enable-postproc --enable-pthreads --enable-x11grab --enable-bzlib --enable-libcelt --enable-libopencore-amrnb --enable- libopencore-amrwb --enable-libdirac --enable-libfreetype --enable- libmp3lame --enable-libopenjpeg --enable-librtmp --enable-libschroedinger --enable-libspeex --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --enable-openal --enable-zlib --disable- debug --extra-cflags='-I/sw/lib/libspeex1/include -I/sw/include -I/usr/X11R6/include' --extra-ldflags='-L/sw/lib/libspeex1/lib -L/sw/lib -L/usr/X11R6/lib' libavutil 51. 10. 0 / 51. 10. 0 libavcodec 53. 7. 0 / 53. 7. 0 libavformat 53. 4. 0 / 53. 4. 0 libavdevice 53. 2. 0 / 53. 2. 0 libavfilter 2. 24. 0 / 2. 24. 0 libswscale 2. 0. 0 / 2. 0. 0 libpostproc 51. 2. 0 / 51. 2. 0 mpeg(49840,0xa025b720) malloc: *** error for object 0x1e2c0e0: incorrect checksum for freed object - object was probably modified after being freed. *** set a breakpoint in malloc_error_break to debug mpeg(49840,0xa025b720) malloc: *** error for object 0x1e2c0e0: incorrect checksum for freed object - object was probably modified after being freed. *** set a breakpoint in malloc_error_break to debug [openal @ 0x200a800] Error: ALC Invalid Device Bus error }}} -- Ticket URL: <http://ffmpeg.org/trac/ffmpeg/ticket/314> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#2659(build system:new): Compiling for i386 on 64bit OSX is hard

#2659: Compiling for i386 on 64bit OSX is hard -------------------------------------+------------------------------------- Reporter: hendrik | Type: defect Status: new | Priority: normal Component: build | Version: git- system | master Keywords: i386 OSX | Blocked By: Darwin | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: When building on OS X 10.7.5 (64bit), it is hard to build a ''small'' or ''shared'' 32bit version. How to reproduce: Specifying `--arch=i386` has no effect, as `configure` differentiates between 32 and 64 bit by compiling some code. Forcing 32bit via `--cc="clang -m32"` works, but then the flag `--enable- small` leads to a compilation error: {{{ CC libavcodec/h264_cabac.o In file included from libavcodec/h264_cabac.c:43: libavcodec/x86/h264_i386.h:137:9: error: ran out of registers during register allocation "mov %1, %6 \n\t" }}} Since the failing code is assembler, specifying `--disable-asm` avoids the failure. What if we use gcc instead of clang? Well, that works partially. I.e. it does not work with shared libs enabled: `--enable-small --enable-shared --disable-static --arch=i386 --cc="gcc -m32"` again leads to {{{ CC libavcodec/h264_cabac.o cc1: error in backend: Ran out of registers during register allocation! make: *** [libavcodec/h264_cabac.o] Error 1 }}} $ gcc --version i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.9.00) $ clang --version Apple clang version 3.1 (tags/Apple/clang-318.0.58) (based on LLVM 3.1svn) Target: x86_64-apple-darwin11.4.2 Thread model: posix -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/2659> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
