I don't think it's so clear cut. Please remember that it is not MP that is generating the "unknown error" in the log. That error might be due to something MP is doing, but so far there is no evidence of that.Question 1: what were the approximate CPU and GPU loads when you played the high bitrate HEVC 4k 10 bit files?Note: I assume you tested with scaling set to 1920x1080 or higher.Question 2: can you play any of the HEVC 4k 10 bit files in MP?I mean, so far the only results you have reported have been for files with bitrate >100 Mb/s. I know that you expect to be able to play them, but from a testing/trouble-shooting perspective it's also important to test the lowest bitrate samples (3 Mb/s etc.). If we find that you can't play even the lowest bitrate HEVC 4k 10 bit files in MP then we could immediately conclude that the problem isn't bandwidth-related.Question 3: did you try MP with different codec or splitter settings?I understand that you think you've proved that the LAV video codec can work with these DXVA Checker results. That's fine... but as explained in my previous reply, that is only one of the components in the graph which could be producing the error. If the problem isn't coming from the LAV video codec, the other components (eg. splitter/source) still have to be checked. Another reason for still testing other video codecs is that if the problem is an MP problem, it could be an MP + LAV problem. Other video codecs may (or may not) work.In short: I'm still in information collection mode. I don't think the information/evidence collected so far is conclusive yet.</blockquote>
