#6949: No support for multiple values in ID3v2.4 tags. -------------------------------------+------------------------------------- Reporter: | Type: defect escapereality | Priority: normal Status: new | Version: Component: | unspecified undetermined | Blocked By: Keywords: ID3 FFprobe | Reproduced by developer: 0 libavformat | Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Altough ''FFmpeg'' states that it has support for ID3v2.4 tags, there is one thing I can't get to work properly. The [http://id3.org/id3v2.4.0-frames ID3v2.4 specifications] state the following: ''There may only be one text information frame of its kind in an tag. All text information frames supports multiple strings, stored as a null separated list, where null is represented by the termination code for the character encoding.'' When I separate the values in a tag with NULL-characters, the values should all be recognized (following the ID3v2.4 specs). However, when I use ''FFprobe'', it only shows the first value. For example [http://mutagen.readthedocs.io/en/latest/man/mid3v2.html mid3v2] shows the tags correctly. [[BR]] Below is (a snippet of) the output of both ''mid3v2'' and ''FFprobe'' with an example file. The '''TCON''' (genre) and '''TPE1''' (artist) contain multiple values. ''mid3v2:'' {{{ mid3v2 --list 01_Infinite_\(Original_Mix\).mp3 IDv2 tag info for 01_Infinite_(Original_Mix).mp3 TALB=Infinite TBPM=150 TCON=Hardstyle / Test / Example / Hard Dance TDRC=2017 TIT2=Infinite (Original Mix) TPE1=B-Front / Second Artist Example TPE2=B-Front TPUB=Roughstate }}} ''FFmpeg:'' {{{ ffprobe 01_Infinite_\(Original_Mix\).mp3 Input #0, mp3, from '01_Infinite_(Original_Mix).mp3': Metadata: title : Infinite (Original Mix) artist : B-Front album : Infinite date : 2017 genre : Hardstyle TBPM : 150 album_artist : B-Front publisher : Roughstate }}} ---- '''Verbose console output FFprobe''' {{{ ffprobe started on 2018-01-07 at 03:20:14 Report written to "ffprobe-20180107-032014.log" Command line: ffprobe -report "01_Infinite_(Original_Mix).mp3" ffprobe version 3.4.1 Copyright (c) 2007-2017 the FFmpeg developers built with gcc 7.2.1 (GCC) 20171128 configuration: --prefix=/usr --disable-debug --disable-static --disable- stripping --enable-avisynth --enable-avresample --enable-fontconfig --enable-gmp --enable-gnutls --enable-gpl --enable-ladspa --enable-libass --enable-libbluray --enable-libfreetype --enable-libfribidi --enable- libgsm --enable-libiec61883 --enable-libmodplug --enable-libmp3lame --enable-libopencore_amrnb --enable-libopencore_amrwb --enable-libopenjpeg --enable-libopus --enable-libpulse --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libv4l2 --enable-libvidstab --enable-libvorbis --enable-libvpx --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxcb --enable-libxml2 --enable-libxvid --enable-shared --enable-version3 libavutil 55. 78.100 / 55. 78.100 libavcodec 57.107.100 / 57.107.100 libavformat 57. 83.100 / 57. 83.100 libavdevice 57. 10.100 / 57. 10.100 libavfilter 6.107.100 / 6.107.100 libavresample 3. 7. 0 / 3. 7. 0 libswscale 4. 8.100 / 4. 8.100 libswresample 2. 9.100 / 2. 9.100 libpostproc 54. 7.100 / 54. 7.100 [NULL @ 0x55a2b5dcdb20] Opening '01_Infinite_(Original_Mix).mp3' for reading [file @ 0x55a2b5dce520] Setting default whitelist 'file,crypto' [mp3 @ 0x55a2b5dcdb20] Format mp3 probed with size=131072 and score=51 id3v2 ver:4 flags:00 len:108428 [mp3 @ 0x55a2b5dcdb20] pad 576 1211 [mp3 @ 0x55a2b5dcdb20] Skipping 0 bytes of junk at 109482.

#9608(undetermined:new): Ffmpeg + VAAPI on Polaris GPU not recovering after corrupt video

#9608: Ffmpeg + VAAPI on Polaris GPU not recovering after corrupt video -------------------------------------+------------------------------------- Reporter: teeedubb | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Hi All, I have been experiencing heavy artifacting in dvb-t live TV streams after corruption in videos with ffmpeg + vaapi + AMD polaris GPU (rx560). The video in question is a live TV stream and I am able to reproduce the issue when the recording is played from a local harddisk. The issue occurs in linux and windows, in kodi, vlc and ffplay and the videos recover OK when played on nvidia and intel gpu's on both windows and linux. The video plays ok if I disable vaapi (most of my testing is done in linux). I have tried updating mesa to the current release, using a 5.15 kernel and tried various operating systems (manjaro, libreelec nighty, ubuntu 20.04, windows 10). output of ffmpeg -hwaccel vaapi -i Downloads/The\ Project.ts -vcodec rawvideo -acodec copy -f matroska -sn - | ffplay -report -i - https://paste.ubuntu.com/p/tP9zrjZ796/ snippets of kodi.log from when the corruption occurs (I can provide more logs) 2021-11-30 20:36:36.863 T:333115 DEBUG <general>: ffmpeg[0x56321c011040X]: [mpegts] Packet corrupt (stream = , dts = 2007374635). 2021-11-30 20:52:18.128 T:366796 DEBUG <general>: ffmpeg[0x56321b9c1730X]: [mpegts] Packet corrupt (stream = , dts = 2209044203). 2021-11-30 20:52:33.301 T:372941 DEBUG <general>: ffmpeg[0x7f559c0dec80X]: [image2] Custom AVIOContext makes o sense and will be ignored with AVFMT_NOFILE format. vainfo http://ix.io/3EE0 <http://ix.io/3EE0> mediainfo of a longer version of the sample video https://paste.ubuntu.com/p/wthYZhVMMf/ video of artefacting https://youtu.be/EJCfi4RP5Pg Sample video (200mb) Corruption occurs at around 4m40s. https://www.dropbox.com/s/aaiwgvsou10aq2w/corruption-recovery-amd.ts?dl=0 I have also uploaded the sample file "corruption-recovery-amd.ts" to the VLC file uploader. I have also received confirmation from two people that they can reproduce the issue on their polaris hardware: https://www.reddit.com/r/ffmpeg/comments/r66bns/any_rx560_or_amd_gpu_owners… "I tried it out and got exactly what you're experiencing, I have a 2gb RX560. If I played the video through about 4:38 in VLC it would drop about 25 frames, and it wouldn't matter where I seeked the video to, it would be all garbled. Not only that, but my gpu utilization would go from about 10% while decoding to 50% once the frames dropped, spiking all over the place. I tried to play the video again, skipping over the corrupted frames, and there were no problems if I skipped over the bad part. I'm sure you're long past worrying about this by now, but I thought I'd pitch in anyway that the same thing happens for me. See screenshot. My CPU at 100% is because I am also transcoding video in the background on CPU." and https://forums.whirlpool.net.au/thread/90x14jy4 "Can confirm the video desync and corruption issue using VLC with RX550 / Polaris12 – it looks like an issue decoding an I frame and the decoder never recovers so corrupt macroblocks appear Playing the video with mpv + hardware acceleration has no issues In Windows VLC with integrated Intel UHD graphics + DXVA2 acceleration, the playback temporarily freezes, skips some frames and then snaps back cleanly to the next I frame" Thanks in advance. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9608> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
