#420(undetermined:new): Sound fragments after seeking

#420: Sound fragments after seeking --------------------------+-------------------------- Reporter: kaptnole | Type: defect Status: new | Priority: important Component: undetermined | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced: 1 Analyzed: 1 | --------------------------+-------------------------- While trying to use FFmpeg libs as a developer I found the following: When decoding sound from some compressed audio formats and doing a seek, the first decoded packet after seeking is buggy. I had this with some mp4 files with aac audio codec and some wmv files with wma audio codec. Looks like some leftovers from internal buffers - but I am using 'avcodec_flush_buffers'! That of course leads to nasty sound noise/clicks. See attached sourcecode. Basically it shows the first few bytes of the first decoded sound packet then seeks back and shows the first packets decoding again. If you use it with some wmv or mp4 file with sound you should see see effect that both outputs at 0 are different but should be equal. Just make sure the sound is not only silence at the first 10 packets. Or am I missing some other flush...whatever function here? I am developing under windows using the actual ffmpeg git version. Confirmed for 32 and 64 bit version, self compiled and downloaded autobuilds. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/420> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

It also might be used as an input parameter, but the list of matching input files would have to be sorted first, I guess, to have a correct sequence of input files. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1452> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#1485: Support for Quicktime CLEF/TAPT atoms ----------------------------------+--------------------------------------- Reporter: brams | Type: enhancement Status: new | Priority: normal Component: avformat | Version: git-master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+--------------------------------------- FFmpeg does not currently support the Quicktime CLEF (Track Clean Aperture Dimensions) and TAPT (Track Aperture Mode Dimensions) atoms. (See https://developer.apple.com/library/mac/#documentation/QuickTime/QTFF/QTFFC…) These atoms are necessary for detecting the correct dimensions for some videos, since they take precedence in Quicktime over the normal TKHD (track header) width/height and over the track PASP (pixel aspect ratio). The attached patch adds support for these atoms. I can provide a sample video if desired. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1485> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#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
