广东百冠陶瓷旗下品牌大全 VLC 3.0 and Chinese AVS+ codec

I he written the decoder for Chinese S in ffmpeg (and by extension in VLC) in 2006. Since then a lot has changed. While that was a "simplified H264", what is in use now in broadcast - whether called S2 or S+ - is a completely different thing. From hearsay it has more similarity to HEVC but I do not he any specification for it. If someone could find out more about that modified VLC 2.26 I would be interested to hear. Ffmpeg contains support for the external library libxs2 but that is only for encoding, maybe someone has authored something similar for decoding?

I believe the bitstream between the different S versions has just enough compatibility for that. The decoder for the "old" S can therefore read the video resolution from the headers but basically fails immediately afterwards - it cannot understand how to decode the content itself. So while hopefully there is an easier approach than reverse engineering - basically impossible - it is not something that just requires a bugfix. Thank you for posting that reference software, I was not aware of it before.
