Qualité du média après traitement
21 juin 2013, parLe bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...)

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.

Use ffmpeg to extract picture from m4v file
31 octobre 2017, par BrianI used a program called MetaZ on my mac to tag all my video files (m4v). I am now trying to use these m4v files in Kodi which requires .nfo files and separate picture files for movie posters, etc. I want to extract the picture that is already in the m4v file.
When I use ffprobe -show_streams, I can see that index4 is a png file (codec_name=png). How do I extract it ? I believe ffmpeg can do it, but can’t figure out how.
Here is the output from ffprobe :
