#10374(avcodec:new): Problems to decode certain h264 keyframes with D3D11VA and DXVA2 hw acceleration

#10374: Problems to decode certain h264 keyframes with D3D11VA and DXVA2 hw acceleration -------------------------------------+------------------------------------- Reporter: Florian | Type: defect Grill | Status: new | Priority: normal Component: avcodec | Version: 6.0 Keywords: H264 dxva2 | Blocked By: d3d11va | Blocking: | Reproduced by developer: 1 Analyzed by developer: 1 | -------------------------------------+------------------------------------- Summary of the bug: I'm currently developing a streaming app for Windows and for my project I use the javacv project to use the native ffmpeg libraries [https://github.com/bytedeco/javacv] Developing the first prototype was quite easy but upon further testing on different machines with different hardware decoders I noticed some strange effects with the D3D11VA and DXVA2 video decoder. It was just not possible to decode certain keyframes but cuvid or the software decoder had no problem to do so. On these problematic keyframes I always received an error when calling {{{ final int err = avcodec_send_packet(this.m_VideoDecoderCtx, this.pkt); }}} The logs printed out ''"Invalid data found when processing input"'' but I was 100% sure that the data was correct so I started to dig into source code and did some research on the internet and I found the issue. It seems that in h264dec.h there is a variable called MAX_SLICES which is set to 32. [https://github.com/FFmpeg/FFmpeg/blob/release/6.0/libavcodec/h264dec.h#L62] This MAX_SLICES value is used here dxva2_h264.c [https://github.com/FFmpeg/FFmpeg/blob/release/6.0/libavcodec/dxva2_h264.c#L…] which leads to the fact that frames with larger slices simply can't be processed. This is strange limitation if you ask me. Other popular ffmpeg forks already increased this limit, e.g. [https://git.1f0.de/gitweb/?p=ffmpeg.git;a=commit;h=550cf548b546d386a6c63435…] In my example I used {{{ this.m_VideoDecoderCtx.err_recognition(this.m_VideoDecoderCtx.err_recognition() | AV_EF_EXPLODE); }}} to get a proper error output but for testing I removed it and the frame that was processed and displayed looked like that [[Image(https://github.com/grill2010/ExampleDXVA2/blob/main/example_data/test…]] This behaviour can be easily reproduced with the latest ffmpeg version. The example h264 keyframe can be downloaded from here [https://github.com/grill2010/ExampleDXVA2/blob/main/example_data/example.h2…] How to reproduce: {{{ % .\ffmpeg.exe -hwaccel dxva2 -i .\example.h264 test.jpg or % .\ffmpeg.exe -hwaccel d3d11va -i .\example.h264 test.jpg ffmpeg version 6.0 and latest SNAPSHOT built via https://www.gyan.dev/ffmpeg/builds/ }}} On the ffmpeg version of javacv there was recently a patch for this small numbers of slices [https://github.com/bytedeco/javacpp- presets/commit/63acf680ef0d95cbdda1b3840450e4333a78bde0] and I can confirm that this fixes the issue completely (at least for D3D11VA). Btw. I found another ticket which might be related to this problem [https://trac.ffmpeg.org/ticket/9771] ---- Like I said a fix was applied to the javacv ffmpeg version so I tried to compile this ffmpeg version for Windows x86_x64 with this increased MAX_SLICES for further testing. D3D11VA works perfectly fine now but I noticed another issue with DXVA2. Still on certain keyframes I received an error but this time a different one. When calling {{{ final int err = avcodec_send_packet(this.m_VideoDecoderCtx, this.pkt); }}} I receive now {{{ [h264 @ 0000027a270a1680] Buffer for type 5 was too small. size: 58752, dxva_size: 55296 [h264 @ 0000027a270a1680] Failed to add bitstream or slice control buffer [h264 @ 0000027a270a1680] hardware accelerator failed to decode picture Error while decoding stream #0:0: Operation not permitted }}} Upon further investigation it turned out that the decoding of these certain keyframes fail because the buffer returned from the IDirectXVideoDecoder_GetBuffer function was too small. And I don't have any explanation why. DXVA2 works perfectly fine btw for h265 (not affected by the MAX_SLICES problem and not by the too small buffer problem). [https://github.com/FFmpeg/FFmpeg/blob/9d70e74d255dbe37af52b0efffc0f93fd7cb6…] I tested this behaviour now on 4 different PCs and the pattern I found is that it works on PCs with AMD or Intel GPUs but if you have an NVIDIA GPU you get this small buffer problem. How to reproduce: {{{ % .\ffmpeg.exe -hwaccel dxva2 -i .\example.h264 test.jpg ffmpeg version with a patch which sets MAX_SLICES in dxva2_h264.c to 256 built via javacv (java-presets build process) }}} I have provided here a Windows x64 ffmpeg build with that MAX_SLICES patch [https://github.com/grill2010/ExampleDXVA2/tree/main/example_data] ---- I know that these are probably two bug reports in one but for me these things are related. The first problem with these small slices are probably an easy fix, the question is why is it like that in the first place? Other hw decoder for example like the dxva2 hevc decoder are overriding this small slice value but not dxva2 h264? Any reason for that? This is actually quite limiting the h264 hw acceleration for DXVA2 and D3D11VA. For the second problem with the too small buffer on DXVA2 I have absolutely no idea what could cause this issue and why it (seemingly) only occur on devices with an NVIDIA GPU. I would like to start some further testing but no idea where to start. I tried to provide as much details as possible if there are any questions just let me know. -- Ticket URL: <https://trac.ffmpeg.org/ticket/10374> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

It fails and get stuck on "No output buffer available, try again later", repeated indefinitely. Speaking of which, exiting with the 'q' key does not work, I have to force kill it with 3 CTRL-C. The h264 hardware encoder does not work as well, stuck in the same way.

This is a lower-level issue than just a pixel format or encoder parameter problem. This "Cannot allocate memory" error for hwupload when dealing with VA-API on AMD GPUs (especially newer ones like Navi 3x) can indicate several things' How to reproduce: {{{ see logs for versions and examples below: }}} --- FFmpeg Bug Report Log --- Generated on: Sat 31 May 22:00:14 BST 2025 --- 1. vainfo output --- Command: vainfo --display drm --device /dev/dri/renderD128 Trying display: drm vainfo: VA-API version: 1.22 (libva 2.22.0) vainfo: Driver version: Mesa Gallium driver 25.1.1-arch1.2 for AMD Radeon RX 7900 XT (radeonsi, navi31, LLVM 19.1.7, DRM 3.61, 6.14.7-arch2-1) vainfo: Supported profile and entrypoints VAProfileH264ConstrainedBaseline: VAEntrypointVLD VAProfileH264ConstrainedBaseline: VAEntrypointEncSlice VAProfileH264Main : VAEntrypointVLD VAProfileH264Main : VAEntrypointEncSlice VAProfileH264High : VAEntrypointVLD VAProfileH264High : VAEntrypointEncSlice VAProfileHEVCMain : VAEntrypointVLD VAProfileHEVCMain : VAEntrypointEncSlice VAProfileHEVCMain10 : VAEntrypointVLD VAProfileHEVCMain10 : VAEntrypointEncSlice VAProfileJPEGBaseline : VAEntrypointVLD VAProfileVP9Profile0 : VAEntrypointVLD VAProfileVP9Profile2 : VAEntrypointVLD VAProfileAV1Profile0 : VAEntrypointVLD VAProfileAV1Profile0 : VAEntrypointEncSlice VAProfileNone : VAEntrypointVideoProc --- 2. pacman -Q mesa output --- Command: pacman -Q mesa mesa 1:25.1.1-2 --- 3. uname -r output (Kernel Version) --- Command: uname -r 6.14.7-arch2-1 --- 4. lspci -k | grep -EA3 'VGA|3D|Display' output (GPU Info) --- Command: lspci -k | grep -EA3 'VGA|3D|Display' lspci: Unable to load libkmod resources: error -2 0b:00.0 VGA compatible controller: Advanced Micro Devices, Inc.

#11622(undetermined:new): Low bitrate data PID in MPEGTS disrupts live output rate

#11622: Low bitrate data PID in MPEGTS disrupts live output rate -------------------------------------+------------------------------------- Reporter: Thierry | Type: defect Lelegard | Status: new | Priority: normal Component: | Version: 7.1 undetermined | Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- During live transcoding of MPEG transport stream, when a data PID has rare packets, the output bitrate suddenly doubles when an input data packet is found. Then, the output bitrate drops to zero (to compensate the previous burst) and then stabilizes again, until the next data packet. Impact: When ffmpeg is used as part of a live transmission chain, the playback is broken on all clients. == ffmpeg version {{{ ffmpeg version 7.1.1 Copyright (c) 2000-2025 the FFmpeg developers built with Apple clang version 17.0.0 (clang-1700.0.13.3) configuration: --prefix=/opt/homebrew/Cellar/ffmpeg/7.1.1_3 --enable- shared --enable-pthreads --enable-version3 --cc=clang --host-c\ flags= --host-ldflags='-Wl,-ld_classic' --enable-ffplay --enable-gnutls --enable-gpl --enable-libaom --enable-libaribb24 --enable-l\ ibbluray --enable-libdav1d --enable-libharfbuzz --enable-libjxl --enable- libmp3lame --enable-libopus --enable-librav1e --enable-lib\ rist --enable-librubberband --enable-libsnappy --enable-libsrt --enable- libssh --enable-libsvtav1 --enable-libtesseract --enable-li\ btheora --enable-libvidstab --enable-libvmaf --enable-libvorbis --enable- libvpx --enable-libwebp --enable-libx264 --enable-libx265 \ --enable-libxml2 --enable-libxvid --enable-lzma --enable-libfontconfig --enable-libfreetype --enable-frei0r --enable-libass --enabl\ e-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libspeex --enable-libsoxr --enable-libzmq --enable-lib\ zimg --disable-libjack --disable-indev=jack --enable-videotoolbox --enable-audiotoolbox --enable-neon libavutil 59. 39.100 / 59. 39.100 libavcodec 61. 19.101 / 61. 19.101 libavformat 61. 7.100 / 61. 7.100 libavdevice 61. 3.100 / 61. 3.100 libavfilter 10. 4.100 / 10. 4.100 libswscale 8. 3.100 / 8. 3.100 libswresample 5. 3.100 / 5. 3.100 libpostproc 58. 3.100 / 58. 3.100 }}} == Reproducer materials Files are available at https://tsduck.io/test/ffmpeg-issue/ Input transport stream is file [https://tsduck.io/test/ffmpeg-issue /ffmpeg-input-2.ts ffmpeg-input-2.ts]. The global bitrate is 50 Mb/s. There is one video and one audio PID. There is also one PES data PID with rare packets, only 8 TS packets in that PID out of 450k packets in the TS. The TS packets in the data PID contains PCR and PTS values. The analysis shows that these PCR and PTS are synchronous with the surrounding video and audio packets (see file [https://tsduck.io/test/ffmpeg-issue/ffmpeg-input-2.pcr-pts-dts.csv ffmpeg-input-2.pcr-pts-dts.csv]). Analysis files of the input TS are available from ffprobe ([https://tsduck.io/test/ffmpeg-issue/ffmpeg-input-2.ffprobe.txt ffmpeg- input-2.ffprobe.txt]) and tsanalyze, part of the TSDuck toolset ([https://tsduck.io/test/ffmpeg-issue/ffmpeg-input-2.tsanalyze.txt ffmpeg- input-2.tsanalyze.txt]). The tests use TSDuck to play the file into ffmpeg and to monitor the packets in the data PID as well as the global bitrate. See https://tsduck.io/ and https://github.com/tsduck/tsduck to get TSDuck. == First test: Demonstrate the problem Test script: [https://tsduck.io/test/ffmpeg-issue/test-ffmpeg-2.sh test- ffmpeg-2.sh] Output: [https://tsduck.io/test/ffmpeg-issue/test-ffmpeg-2.log test- ffmpeg-2.log] The input TS file is played at its native speed, approximately 50 Mb/s. The complete play time is approximately one minute. Using tsp plugins, part of TSDuck, the input data packets (PID 6000) are traced and the global bitrate is displayed once per second (tag "before- ffmpeg"). The output of tsp is piped into ffmpeg. All codecs are set to "copy". However, for some reason, the AES3 PCM audio is transcoded to mp2 (mp3float) audio, reducing the global bitrate by 2 Mb/s. The data PID uses "-map 0:d -c:d copy". The full ffmpeg command is: {{{ ffmpeg -loglevel error -copyts \ -f mpegts -i - \ -map 0:d -c:d copy \ -map 0:v -c:v copy \ -map 0:a -c:v copy \ -mpegts_start_pid 100 \ -f mpegts - }}} The output of ffmpeg is piped into another tsp where the output data packets (PID 100) are traced and the global bitrate is displayed once per second (tag "after-ffmpeg"). The ffmpeg input bitrate remains steady all along the test, around 50.6 Mb/s. The ffmpeg output bitrate is initially stable around 48 Mb/s (due to audio transcoding from PCM to MP2). However, each time a data packet arrives, the ffmpeg output bitrate suddenly doubles around 120 Mb/s, then drop to zero (because ffmpeg is probably starving, waiting for input) and then stabilizes again around 48 Mb/s. Note that there is a huge latency of 10 seconds between the first input packet in ffmpeg and its first output packet. Therefore, there are enough data in the ffmpeg buffer to feed the output burst. == Second test: The problem disappears when the data PID is removed Test script: [https://tsduck.io/test/ffmpeg-issue/test-ffmpeg-3.sh test- ffmpeg-3.sh] Output: [https://tsduck.io/test/ffmpeg-issue/test-ffmpeg-3.log test- ffmpeg-3.log] The second test is identical to the first one with one exception: the data PID is removed from the TS before going into ffmpeg ("-P filter -n -p 6000"). This time, we see that the ffmpeg output bitrate remains steady all the time, demonstrating that the problem is created by the data packets. -- Ticket URL: <https://trac.ffmpeg.org/ticket/11622> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

However, it appears this does not work when using the FFREPORT environment variable to log to files. Would be great if these timestamp prefixes also worked for FFREPORT.
