Failed to decode h264 key frame with DXVA2.0 because returned buffer is to small
16 mai 2023, par grill2010I hava a strange problem on Windows with DXVA2 h264 decoding. I recently figured out a ffmpeg decoding limitation for DXVA2 and D3D11VA on Windows and how to solve it, this solution completly fixes the problem with D3D11VA but DXVA2 still has some problems with certain keyframes. 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. FFmpeg is printing out these logs when the decoding fails :


Error: [h264 @ 0000028b2e5796c0] Buffer for type 5 was too small. size: 58752, dxva_size: 55296
Error: [h264 @ 0000028b2e5796c0] Failed to add bitstream or slice control buffer
Error: [h264 @ 0000028b2e5796c0] hardware accelerator failed to decode picture


Why is this returned buffer too low ? What kind of factors inside ffmpeg do have an effect on this buffer size or is this a limitation of DXVA2 in general ? All other decoders like Cuvid, D3D11VA or the software decoder are not affected by this problem and can decode all keyframes.


I have an example javacv project on github that can reproduce the problem. I also provide the source code of the main class here. The keyframe example data with prepended SPS and PPS in hex form can be downloaded here.

module.exports.details = details;
module.exports.plugin = plugin;


Tried transcoding 4k files down to 1080p but it fails due to that undefined error. All Res 1080p and lower that I have tried work correctly


EDIT : I used Console.log and got this back
