Specifically, memory is allocated using av_strdup() in line 472: mapchan = av_strdup(arg); However, the function contains multiple exit_program() calls that terminate the program without freeing the allocated memory in lines 507, 513, 519, and 533. -- Ticket URL: <https://trac.ffmpeg.org/ticket/10342> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

It was correctly freed at the end of the block. However, [https://github.com/FFmpeg/FFmpeg/commit/6691eee48c7f08caf479ce3562a1c834475… that one] buried the `av_free()` call into `ffio_rewind_with_probe_data()`. Unsurprisingly, [https://github.com/FFmpeg/FFmpeg/commit/e6e8cc8ce9c2a398fbb51254a5067f4bd3c… a subsequent patch] made it so this call is skipped in the case of custom io, so the buffer is never freed. A simple `av_free()` after the call to `avio_seek()` on [https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/img2dec.c#L346 img2dec.c:346] might do the job. {{{ int probe_buffer_size = 2048; uint8_t *probe_buffer = av_realloc(NULL, probe_buffer_size + AVPROBE_PADDING_SIZE); // ... if (s1->flags & AVFMT_FLAG_CUSTOM_IO) { // this leaks probe_buffer because av_free() isn't called avio_seek(s1->pb, 0, SEEK_SET); } else ffio_rewind_with_probe_data(s1->pb, &probe_buffer, probe_buffer_size); }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/4908> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#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

There was a patch (https://patchwork.ffmpeg.org/project/ffmpeg/patch/20240321170219.1487-1-Pri…) fixed this for 7.0.x but it no longer applies to 7.1. I'm using an AMD Radeon RX 6650 XT display card and so my only options are HEVC and AVC.
