It tries to share the functions that are used for processing user/SEI data as they are, even the parts that are not intended to be used by QSV (like the picture structure stuff for H.264 or tmpgexs in case of MPEG-1/2). 2. It tries to keep the functions where they are, leading to the insanely long Makefile line in patch 6/6 (which I believe to be still incomplete: mpeg12dec.o pulls in mpegvideo.o mpegvideo_dec.o (which in turn pull in lots of dsp stuff) and where is h264dsp.o? (it seems like there is a reliance on the H.264 parser for this)). This is the opposite of modularity. 3. It just puts a huge Mpeg1Context in the QSVContext, although only a miniscule part of it is actually used. One should use a small context of its own instead. 4. It does not take into account that buffers need to be padded to be usable by the GetBit-API. (I have made an attempt to factor out the common parts of H.264 and H.265 SEI handling, which should make this here much easier.) - Andreas

I agree to your other points (1-3). Not that I wouldn't have been aware of those implications, I've just been afraid that larger refactorings could have minimized acceptance. > (I have made an attempt to factor out the common parts of H.264 and > H.265 SEI handling, which should make this here much easier.) Your patchset would in fact be very helpful and allow me to provide a much better and focused revision. Though, it is still pending at this time - are you planning to push it? Thanks, softworkz
Missing SEI information has always been a major drawback when using the QSV decoders. I used to think that there's no chance to get at the data without explicit implementation from the MSDK side (or doing something weird like parsing in parallel). It turned out that there's a hardly known api method that provides access to all SEI (h264/hevc) or user data (mpeg2video). This allows to get things like closed captions, frame packing, display orientation, HDR data (mastering display, content light level, etc.) without having to rely on those data being provided by the MSDK as extended buffers. The commit "Implement SEI parsing for QSV decoders" includes some hard-coded workarounds for MSDK bugs which I reported: https://github.com/Intel-Media-SDK/MediaSDK/issues/2597#issuecomment-1072795311 But that doesn't help. Those bugs exist and I'm sharing my workarounds, which are empirically determined by testing a range of files. If someone is interested, I can provide private access to a repository where we have been testing this. Alternatively, I could also leave those workarounds out, and just skip those SEI types. In a previous version of this patchset, there was a concern that payload data might need to be re-ordered. Meanwhile I have researched this carefully and the conclusion is that this is not required.
