#8948: CUDA decoder fails on certain files. -------------------------------------+------------------------------------- Reporter: ericbg | Type: defect Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: When I try to use a CUDA decoder on a specific file, I end up getting an error "Using more than 32 (42) decode surfaces might cause nvdec to fail." and then it won't use CUDA to process the file.. The number in the brackets seems to be "29 + threads"; for example, I have a 12-thread Ryzen 3600 and when I don't specify threads it says 42 (for some reason internally 'threads' is set to 13 even though I don't have that many?), when I try `-threads 4` it says 33, and when I try `-threads 3` it just works! This is where the error is from: https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/nvdec.c#L401. The problem is also file-specific; after I re-enc the file, it works just fine without any fiddling. Computer: Ryzen 3600, Nvidia 1660Ti, Windows 10 Pro N.

#6763(swscale:new): swscale: Out-of-bounds memory accesses

#6763: swscale: Out-of-bounds memory accesses ---------------------------------+--------------------------------------- Reporter: Gramner | Type: defect Status: new | Priority: normal Component: swscale | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ---------------------------------+--------------------------------------- Many assembly functions in swscale will read past the end of their input buffers which causes segfaults and/or bus errors if the buffer happens to be located near the end of a memory page and the next page is invalid. Aligning input buffers isn't even enough for formats like RGB24 (and requiring alignment would be a bad idea anyway since it wouldn't work with memory-mapped input files for example). Using swscale with x264 CLI seems to be a fairly consistent way to trigger such out-of-bounds crashes. This command line for example will cause segfaults in ff_rgb24ToY_avx(): ./x264 -o /dev/null --input-csp rgb --input-res 512x512 <any_input_file> If asm is disabled in swscale the problem goes away. -- Ticket URL: <https://trac.ffmpeg.org/ticket/6763> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#8343(avcodec:new): h261dec doesn't mark keyframes

#8343: h261dec doesn't mark keyframes ----------------------------------+---------------------------------- Reporter: Lastique | Type: defect Status: new | Priority: normal Component: avcodec | Version: 4.2 Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+---------------------------------- h261dec does not set AVFrame::key_frame field on keyframes. As a side effect, frame skipping except keyframes doesn't work (all frames are skipped). In H.261, keyframes are normally indicated by the Freeze Picture Release bit in the Picture Header of a frame, but h261dec ignores that bit. h261enc behavior is to set that bit on keyframes. The problem was discovered in a client application that uses ffmpeg through its C API. I'm not sure if it can be reproduced through command line. Attached is a patch that fixes the problem. The patch has been posted on ffmpeg-devel: https://lists.ffmpeg.org/pipermail/ffmpeg-devel/2019-October/252145.html -- Ticket URL: <https://trac.ffmpeg.org/ticket/8343> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

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.

#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

#6389(avformat:new): Support H.265 over Adobe HTTP-FLV or RTMP

#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

Accepting gzip'd playlist files can both save bandwidth and dramatically improve playback performance.

#4888(avcodec:new): 62bd8deef causes a regression in HEVC decoding

#4888: 62bd8deef causes a regression in HEVC decoding ----------------------------------+-------------------------------------- Reporter: staalebk | Type: defect Status: new | Priority: normal Component: avcodec | Version: git-master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+-------------------------------------- Summary of the bug: I'm trying to extract a thumb from the middle of a live TS, containing one HEVC-stream. Before this patch I would always get a good looking thumb, but with this patch I would for the most part get a mostly gray frame. If I generates a few more thumbnails i see that it eventually spits out the same frame that ffmpeg before this patch produced as the first thumb, and it looks OK. However it is much more blocky than what the previous ffmpeg produced.

#9412: HEVC fails to seek on keyframe -----------------------------------+-------------------------------------- Reporter: SuRGeoNix | Type: defect Status: new | Priority: important Component: avformat | Version: git-master Keywords: hevc seek | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+-------------------------------------- I'm using av_seek_frame and even if it returns 0 pb will not be at an actual keyframe.
