I'd love to know if it's possible to find out which codecs are supported by a particular libavcodec.so library/file. I have no option of running it, it's for a different CPU architecture (ARM). `libavcodec.so.58.18.100: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, stripped` -- Ticket URL: <https://trac.ffmpeg.org/ticket/10328> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10321(avformat:new): mov_channel_layout[] table possible issues

#10321: mov_channel_layout[] table possible issues ----------------------------------+--------------------------------------- Reporter: Tim | Type: enhancement Status: new | Priority: normal Component: avformat | Version: git-master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+--------------------------------------- Note: this is kind of a "thinking out loud" thing, possibly worth discussing anyway. Example: https://git.ffmpeg.org/gitweb/ffmpeg.git/blob/a3f4916:/libavformat/isom.c#l… {{{ { AV_CH_LAYOUT_7POINT1, (128<<16) | 8}, // kCAFChannelLayoutTag_MPEG_7_1_C }}} https://developer.apple.com/library/archive/documentation/MusicAudio/Refere… {{{ kCAFChannelLayoutTag_MPEG_7_1_C = (128<<16) | 8, // L R C LFE Ls Rs Rls Rrs }}} Thus: {{{ L | R | C | LFE | BL | BR | SL | SR AV_CH_LAYOUT_7POINT1 L | R | C | LFE | Ls | Rs | Rls | Rrs kCAFChannelLayoutTag_MPEG_7_1_C }}} BL == Ls (kCAFChannelLabel_LeftSurround) BR == Rs (kCAFChannelLabel_RightSurround) but SL (kCAFChannelLabel_LeftSurroundDirect) != Rls (kCAFChannelLabel_RearSurroundLeft) and SR (kCAFChannelLabel_RightSurroundDirect) != Rls (kCAFChannelLabel_RearSurroundRight) …also, perhaps importantly, as far as I can understand, SL and SR are supposedly closer to the front channels than BL/Ls and BR/Rs whereas Rls Rrs are behind BL/Ls and BL/Rs, making the mapping rather problematic? On the other hand: {{{ L | R | C | LFE | BL | BR | FLC | FRC AV_CH_LAYOUT_7POINT1_WIDE_BACK L | R | C | LFE | Ls | Rs | Lc | Rc kCAFChannelLayoutTag_MPEG_7_1_A }}} but there is no mapping for it in the mov_channel_layout table. {{{ L | R | C | LFE | SL | SR | FLC | FRC AV_CH_LAYOUT_7POINT1_WIDE L | R | C | LFE | Ls | Rs | Lc | Rc kCAFChannelLayoutTag_MPEG_7_1_A }}} exists with SL == Ls and SR == Rs, which is also used by AV_CH_LAYOUT_5POINT1 == kCAFChannelLayoutTag_MPEG_5_1_A and several other mappings, but is somewhat less problematic since there are no back channels in the corresponding AV_CH_LAYOUTs. Also: {{{ L | R | C | LFE | BL | BR | BC AV_CH_LAYOUT_6POINT1_BACK L | R | C | LFE | Ls | Rs | Cs kCAFChannelLayoutTag_MPEG_6_1_A }}} seems suitable but is absent from the table. This would not work, on the other hand: {{{ L | R | C | LFE | BC | SL | SR AV_CH_LAYOUT_6POINT1 L | R | C | LFE | Ls | Rs | Cs kCAFChannelLayoutTag_MPEG_6_1_A }}} (but does not exist in the table, just noteworthy) Finally/FWIW https://developer.apple.com/documentation/coreaudiotypes/1572101-audio_chan… Does list some additional WAVE-specific layout tags which are not present in the CAF Channel Layout Chunk specification, for example: kAudioChannelLayoutTag_WAVE_7_1 = (189U<<16) | 8 -- Ticket URL: <https://trac.ffmpeg.org/ticket/10321> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10322: Allow ffconcat.txt inside ffconcat.txt to have "unsafe" URIs -------------------------------------+------------------------------------- Reporter: dejavuyeah | Type: defect Status: new | Priority: important Component: ffmpeg | Version: 4.0.6 Keywords: ffmpeg | Blocked By: concat concatenate https http | Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- [[Image( == Summary of the bug: By default, `ffconcat version 1.0` would "set the `safe` option to `1` if it was `-1`" ([http://underpop.online.fr/f/ffmpeg/help/concat-2.htm.gz] Unfortunately, due to a bug, an `ffmpeg` command would ignore the `-safe 0` option in sub`ffconcat.txt`s, allowing ffmpeg to override the `safe` option. The bug seems to be codec-agnostic. == How to reproduce: Filesystem and command output is referenced and fully duplicated at at [https://github.com/filipinowastaken/bbb-ffmpeg] In order to fully reproduce the bug, `git clone` the repo and `cd` to the directory. It probably looks like this but don't take my word for it. ` git clone https://github.com/filipinowastaken/bbb-ffmpeg.git && cd bbb- ffmpeg ` or you can also alternatively download the zip of the repo at [https://github.com/filipinowastaken/bbb- ffmpeg/archive/refs/heads/main.zip]. Given an ffconcat file that looks like this, named `concat_link_to_ffconcat_whttp.txt`: {{{ ffconcat version 1.0 file 'x.mp4' file 'y.mp4' file 'z.mp4' file 'concat_http.txt' }}} And given `concat_http.txt`: {{{ ffconcat version 1.0 file 'https://github.com/filipinowastaken/bigbuckbunny/raw/main/x.mp4' file 'https://github.com/filipinowastaken/bigbuckbunny/raw/main/y.mp4' file 'https://github.com/filipinowastaken/bigbuckbunny/raw/main/z.mp4' }}} And given command `ffmpeg -v verbose -f concat -safe 0 -protocol_whitelist "file,http,https,tcp,tls" -i concat_link_to_ffconcat_whttp.txt output_link_to_ffconcat_whttp.mp4` It would concat the local files successfully, but due to ffmpeg's [https://www.urbandictionary.com/define.php?term=forceation forceation] of the `safe` URIs to `1` ('ffconcat version 1.0' ... also sets the 'safe' option to '1' if it was '-1'), the command would fail when ffmpeg reads the file. {{{ % ffmpeg -v verbose -f concat -safe 0 -protocol_whitelist "file,http,https,tcp,tls" -i concat_link_to_ffconcat_whttp.txt output_link_to_ffconcat_whttp.mp4 ffmpeg version 2023-04-12-git-1179bb703e-full_build-www.gyan.dev Copyright (c) 2000-2023 the FFmpeg developers built with gcc 12.2.0 (Rev10, Built by MSYS2 project) configuration: --enable-gpl --enable-version3 --enable-static --disable- w32threads --disable-autodetect --enable-fontconfig --enable-iconv --enable-gnutls --enable-libxml2 --enable-gmp --enable-bzlib --enable-lzma --enable-libsnappy --enable-zlib --enable-librist --enable-libsrt --enable-libssh --enable-libzmq --enable-avisynth --enable-libbluray --enable-libcaca --enable-sdl2 --enable-libaribb24 --enable-libdav1d --enable-libdavs2 --enable-libuavs3d --enable-libzvbi --enable-librav1e --enable-libsvtav1 --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxavs2 --enable-libxvid --enable-libaom --enable-libjxl --enable-libopenjpeg --enable-libvpx --enable-mediafoundation --enable- libass --enable-frei0r --enable-libfreetype --enable-libfribidi --enable- liblensfun --enable-libvidstab --enable-libvmaf --enable-libzimg --enable- amf --enable-cuda-llvm --enable-cuvid --enable-ffnvcodec --enable-nvdec --enable-nvenc --enable-d3d11va --enable-dxva2 --enable-libvpl --enable- libshaderc --enable-vulkan --enable-libplacebo --enable-opencl --enable- libcdio --enable-libgme --enable-libmodplug --enable-libopenmpt --enable- libopencore-amrwb --enable-libmp3lame --enable-libshine --enable-libtheora --enable-libtwolame --enable-libvo-amrwbenc --enable-libcodec2 --enable- libilbc --enable-libgsm --enable-libopencore-amrnb --enable-libopus --enable-libspeex --enable-libvorbis --enable-ladspa --enable-libbs2b --enable-libflite --enable-libmysofa --enable-librubberband --enable- libsoxr --enable-chromaprint libavutil 58. 6.100 / 58. 6.100 libavcodec 60. 9.100 / 60. 9.100 libavformat 60. 4.101 / 60. 4.101 libavdevice 60. 2.100 / 60. 2.100 libavfilter 9. 5.100 / 9. 5.100 libswscale 7. 2.100 / 7. 2.100 libswresample 4. 11.100 / 4. 11.100 libpostproc 57. 2.100 / 57. 2.100 [h264 @ 000001774dda0e40] Reinit context to 1280x720, pix_fmt: yuv420p [mov,mp4,m4a,3gp,3g2,mj2 @ 000001774dd8f6c0] Auto-inserting h264_mp4toannexb bitstream filter [h264 @ 000001774dd94c00] Reinit context to 1280x720, pix_fmt: yuv420p Input #0, concat, from 'concat_link_to_ffconcat_whttp.txt': Duration: N/A, start: -0.023220, bitrate: 1489 kb/s Stream #0:0(und): Video: h264 (High), 1 reference frame (avc1 / 0x31637661), yuv420p(progressive, left), 1280x720 [SAR 1:1 DAR 16:9], 1364 kb/s, 24 fps, 24 tbr, 12288 tbn Metadata: handler_name : (C) 2007 Google Inc. v08.13.2007. vendor_id : [0][0][0][0] encoder : Lavc60.9.100 libx264 Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 125 kb/s Metadata: handler_name : (C) 2007 Google Inc. v08.13.2007. vendor_id : [0][0][0][0] Stream mapping: Stream #0:0 -> #0:0 (h264 (native) -> h264 (libx264)) Stream #0:1 -> #0:1 (aac (native) -> aac (native)) Press [q] to stop, [?] for help [h264 @ 000001774ddde3c0] Reinit context to 1280x720, pix_fmt: yuv420p [graph_1_in_0_1 @ 000001774efa2240] tb:1/44100 samplefmt:fltp samplerate:44100 chlayout:stereo [graph 0 input from stream 0:0 @ 000001774efa2840] w:1280 h:720 pixfmt:yuv420p tb:1/12288 fr:24/1 sar:1/1 [libx264 @ 000001774de3cbc0] using SAR=1/1 [libx264 @ 000001774de3cbc0] using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX [libx264 @ 000001774de3cbc0] profile High, level 3.1, 4:2:0, 8-bit [libx264 @ 000001774de3cbc0] 264 -
