#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

#6389: Support H.265 over Adobe HTTP-FLV or RTMP ----------------------------------+--------------------------------------- Reporter: winlin | Type: task Status: new | Priority: normal Component: avformat | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+--------------------------------------- FFMPEG is a great project, thank everyone's awesome work! Adobe HTTP-FLV or RTMP is the defacto protocol for live streaming over internet and almost all encoders support pushing stream to server or CDN over RTMP protocol, while player like Adobe Flash or Android ExoPlayer or FFMPEG also support HTTP-FLV. Although H.265 is supported by HLS and TS, we can also delivery H.265 over HTTP-TS for realtime live streaming service, but CDNs are more friendly to RTMP/HTTP-FLV. For example, all, that's all, not some, all live streaming service in China now are using RTMP/HTTP-FLV for 3-5s latency, none of them chooses HLS for its large latency. Maybe realtime live streaming is not popular in the US, but I think it's only because the CDN is not very good at delivery RTMP/HTTP-FLV. I know some friends in the UK and US are now build the realtime CDN themselves, some use [NGINX-RTMP](https://github.com/arut/nginx-rtmp-module) like facebook, others using [SRS](https://github.com/ossrs/srs) to delivery realtime live streaming: {{{ Encoder ====RTMP====> SRS(Cluster) ====RTMP/HTTP-FLV====> Player }}} Now, it work very good for H.264+AAC over RTMP/HTTP-FLV for 3-5s realtime live streaming service, what about H.265? Is there any plan to support H.265 over HTTP-FLV/RTMP? -- Ticket URL: <https://trac.ffmpeg.org/ticket/6389> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10125: ffmpeg-3.4.12 does not build (i686-w64-mingw32) ---------------------------------------+---------------------------------- Reporter: Carlo Bramini | Type: defect Status: new | Priority: normal Component: build system | Version: 3.4.12 Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ---------------------------------------+---------------------------------- I tried to build ffmpeg-3.4.12, which is the last one supporting Windows XP, but it fails to compile the resource file for Windows. Running verbose build, it prints this output on the console: {{{ $ make V=1 i686-w64-mingw32-windres -I. -Isrc/ --preprocessor "i686-w64-mingw32-gcc -E -xc-header -DRC_INVOKED -MMD -MF libavdevice/avdeviceres.d -MT libavdevice/avdeviceres.o" -o libavdevice/avdeviceres.o /home/carlo/packages/ffmpeg/mingw64-i686-ffmpeg-3.4.12-1.noarch/src/ffmpeg-3.4.12/libavdevice/avdeviceres.rc /bin/sh: i686-w64-mingw32-gcc -E -xc-header -DRC_INVOKED -MMD -MF libavdevice/avdeviceres.d -MT libavdevice/avdeviceres.o: No such file or directory make: *** [/home/carlo/packages/ffmpeg/mingw64-i686-ffmpeg-3.4.12-1.noarch/src/ffmpeg-3.4.12/ffbuild/common.mak:86: libavdevice/avdeviceres.o] Error 1 }}} I found a solution by comparing ffbuild/common.mak between this version and the latest 5.1.2, which has already fixed this bug. According to this reply that I received on the mailing list: http://ffmpeg.org/pipermail/ffmpeg-devel/2022-December/305046.html a patch already exists in commit f9626d1065c43f1d51afe66bdf988b9f33729440. Is it possible to apply this patch also to 3.4 branch, to allow building this version on Windows, when an updated release will be made public? Thank you very much. Sincerely. -- Ticket URL: <https://trac.ffmpeg.org/ticket/10125> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
