#7132(avfilter:new): Add threading capabilities to overlay filter

#7132: Add threading capabilities to overlay filter -------------------------------------+------------------------------------- Reporter: zerodefect | Type: Status: new | enhancement Component: avfilter | Priority: normal Keywords: | Version: git- Blocking: | master Analyzed by developer: 0 | Blocked By: | Reproduced by developer: 0 -------------------------------------+------------------------------------- I've been running some (entirely unscientific) benchmarks on the overlay filter. Compositing a frame at 1080p (YUV 422 planar) over another frame takes in the region of around 20ms on my system. Admittedly, my system isn't the latest and greatest. Having inspected the latest source code, it feels as if the overlay filter (vf_overlay.c) could benefit from threading. The trick would be to somehow keep both the current inlining while incorporating the addition of threading. Without inlining my tests indicate that performance degrades significantly. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7132> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#7185(avformat:new): Preserve codec delay/initial padding and trailing padding during muxing
by FFmpeg 02 May '18

#7185: Preserve codec delay/initial padding and trailing padding during muxing ----------------------------------+--------------------------------------- Reporter: mkver | Type: enhancement Status: new | Priority: wish Component: avformat | Version: git-master Keywords: mkv mov | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+--------------------------------------- Currently initial and trailing padding data is often lost during muxing even when the target container has features that can be used to retain it. I'm thinking about Matroska and mp4 here, but there might be other containers with these capabilities. For Matroska, the CodecDelay track header field is only written for Opus although it could be written for all audio tracks. Also, the DiscardPadding element isn't used for end trimming for most encoders (Opus, libopus libmp3lame and the experimental vorbis encoder being exceptions; here the encoder adds the needed AV_PKT_DATA_SKIP_SAMPLES side data; probably there are other exceptions). For mp4, edit lists could be used to signal the actual encoder delay; and sometimes this is already done so, but not by design, but by accident/as a side-effect of the shifting of timestamps to make the dts nonnegative. Here is a test*: {{{ % ffmpeg.exe -f lavfi -i anullsrc -filter:a "atrim=start_sample=0:end_sample=10000" -c:a aac -f framehash -hash crc32 - #format: frame checksums #version: 2 #hash: CRC32 #extradata 0, 5, c72331cb #software: Lavf58.13.100 #tb 0: 1/44100 #media_type 0: audio #codec_id 0: aac #sample_rate 0: 44100 #channel_layout 0: 3 #channel_layout_name 0: stereo #stream#, dts, pts, duration, size, hash 0, -1024, -1024, 1024, 23, 5a2d9cda 0, 0, 0, 1024, 6, 595037cd 0, 1024, 1024, 1024, 6, 595037cd 0, 2048, 2048, 1024, 6, 595037cd 0, 3072, 3072, 1024, 6, 595037cd 0, 4096, 4096, 1024, 6, 595037cd 0, 5120, 5120, 1024, 6, 595037cd 0, 6144, 6144, 1024, 6, 595037cd 0, 7168, 7168, 1024, 6, 595037cd 0, 8192, 8192, 1024, 6, 595037cd 0, 9216, 9216, 784, 6, 595037cd }}} When muxing this into mp4, there is an edit list showing that the first 1024 samples should be discarded which means that the dts of the first packet is -1024: {{{ % ffmpeg.exe -f lavfi -i anullsrc -filter:a "atrim=start_sample=0:end_sample=10000" -c:a aac test.mp4 ffmpeg -i test.mp4 -c copy -f framehash -hash crc32 - #format: frame checksums #version: 2 #hash: CRC32 #extradata 0, 5, c72331cb #software: Lavf58.13.100 #tb 0: 1/44100 #media_type 0: audio #codec_id 0: aac #sample_rate 0: 44100 #channel_layout 0: 3 #channel_layout_name 0: stereo #stream#, dts, pts, duration, size, hash 0, -1024, -1024, 1024, 23, 5a2d9cda, S=1, 10, be66397a 0, 0, 0, 1024, 6, 595037cd 0, 1024, 1024, 1024, 6, 595037cd 0, 2048, 2048, 1024, 6, 595037cd 0, 3072, 3072, 1024, 6, 595037cd 0, 4096, 4096, 1024, 6, 595037cd 0, 5120, 5120, 1024, 6, 595037cd 0, 6144, 6144, 1024, 6, 595037cd 0, 7168, 7168, 1024, 6, 595037cd 0, 8192, 8192, 1024, 6, 595037cd 0, 9216, 9216, 751, 6, 595037cd }}} But if we start the audio a bit later (at sample 500), only the first 524 samples are discarded via the edit list (because the edit list by design is only there to make the dts non-negative) and time from 0 to 500/44100 s now contains valid audio whereas previously there was nothing: {{{ ffmpeg.exe -f lavfi -i anullsrc -filter:a "atrim=start_sample=500:end_sample=10500" -c:a aac test2.mp4 ffmpeg -i test2.mp4 -c copy -f framehash -hash crc32 - #format: frame checksums #version: 2 #hash: CRC32 #extradata 0, 5, c72331cb #software: Lavf58.13.100 #tb 0: 1/44100 #media_type 0: audio #codec_id 0: aac #sample_rate 0: 44100 #channel_layout 0: 3 #channel_layout_name 0: stereo #stream#, dts, pts, duration, size, hash 0, -524, -524, 1024, 23, 5a2d9cda, S=1, 10, d740a07e 0, 500, 500, 1024, 6, 595037cd 0, 1524, 1524, 1024, 6, 595037cd 0, 2548, 2548, 1024, 6, 595037cd 0, 3572, 3572, 1024, 6, 595037cd 0, 4596, 4596, 1024, 6, 595037cd 0, 5620, 5620, 1024, 6, 595037cd 0, 6644, 6644, 1024, 6, 595037cd 0, 7668, 7668, 1024, 6, 595037cd 0, 8692, 8692, 1024, 6, 595037cd 0, 9716, 9716, 780, 6, 595037cd }}} *: All tests have been done with this version of ffmpeg: {{{ ffmpeg version N-90920-ge07b1913fc Copyright (c) 2000-2018 the FFmpeg developers built with gcc 7.3.0 (GCC) configuration: --disable-static --enable-shared --enable-gpl --enable- version3 --enable-sdl2 --enable-bzlib --enable-fontconfig --enable-gnutls --enable-iconv --enable-libass --enable-libbluray --enable-libfreetype --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libtheora --enable-libtwolame --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libzimg --enable-lzma --enable-zlib --enable-gmp --enable-libvidstab --enable-libvorbis --enable-libvo-amrwbenc --enable- libmysofa --enable-libspeex --enable-libxvid --enable-libaom --enable- libmfx --enable-amf --enable-ffnvcodec --enable-cuvid --enable-d3d11va --enable-nvenc --enable-nvdec --enable-dxva2 --enable-avisynth libavutil 56. 18.100 / 56. 18.100 libavcodec 58. 19.100 / 58. 19.100 libavformat 58. 13.100 / 58. 13.100 libavdevice 58. 4.100 / 58. 4.100 libavfilter 7. 21.100 / 7. 21.100 libswscale 5. 2.100 / 5. 2.100 libswresample 3. 2.100 / 3. 2.100 libpostproc 55. 2.100 / 55. 2.100 }}} This is one completely unrelated commit behind git-master. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7185> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#7183: Concat very slow with dvd_subtitles -------------------------------------+------------------------------------- Reporter: oerg866 | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: FFMPEG will process concatenation of vob files with subtitles agonizingly slowly (less than real time speed on my i9-7900x with stream copy!) and the progress display is erratic. How to reproduce: {{{ ffmpeg f concat -safe 0 -i list.txt -vcodec copy -acodec pcm_s16be -scodec copy mux.vob }}} list.txt contains several vob files with MPEG2 video, LPCM audio and subtitles. Separate concat with several files that have video, audio and subtitles and then remuxing to a final output works infinitely faster, like so: {{{ ffmpeg -f concat -safe 0 -i list.txt -vcodec copy -acodec pcm_s16be mux1.vob ffmpeg -f concat -safe 0 -i list.txt -vn -an -scodec copy mux2.vob ffmpeg -i mux1.vob -i mux2.vob -map 0:v -map 0:a -map 1:s -vcodec copy -acodec pcm_s16be -scodec copy mux.vob }}} HOWEVER, this breaks subtitle timing (they play about two seconds too early. Also potential bug?) Below is a sample of ffmpeg's console output with the buggy command. {{{ C:\OUTPUT>ffmpeg -f concat -safe 0 -i list.txt -vcodec copy -acodec pcm_s16be -scodec copy mux.vob ffmpeg version N-86691-gc885356 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 7.1.0 (GCC) configuration: --enable-gpl --enable-version3 --enable-cuda --enable- cuvid --enable-d3d11va --enable-dxva2 --enable-libmfx --enable-nvenc --enable-avisynth --enable-bzlib --enable-fontconfig --enable-frei0r --enable-gnutls --enable-iconv --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libfreetype --enable-libgme --enable-libgsm --enable-libilbc --enable-libmodplug --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenh264 --enable-libopenjpeg --enable-libopus --enable-librtmp --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvo-amrwbenc --enable-libvorbis --enable- libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable- libx265 --enable-libxavs --enable-libxvid --enable-libzimg --enable-lzma --enable-zlib libavutil 55. 67.100 / 55. 67.100 libavcodec 57.100.103 / 57.100.103 libavformat 57. 75.100 / 57. 75.100 libavdevice 57. 7.100 / 57. 7.100 libavfilter 6. 94.100 / 6. 94.100 libswscale 4. 7.101 / 4. 7.101 libswresample 2. 8.100 / 2. 8.100 libpostproc 54. 6.100 / 54. 6.100 Guessed Channel Layout for Input Stream #0.1 : stereo Input #0, concat, from 'list.txt': Duration: N/A, start: 0.000000, bitrate: N/A Stream #0:0: Video: mpeg2video (Main), yuv420p(tv, bottom first), 720x576 [SAR 16:15 DAR 4:3], 25 fps, 25 tbr, 90k tbn, 90k tbc Stream #0:1: Audio: pcm_dvd, 48000 Hz, stereo, s16, 1536 kb/s Stream #0:2: Subtitle: dvd_subtitle File 'mux.vob' already exists.
