No it doesn't help with vaapi disabled.
Oh I also retry ffplay with another file and I have this message :

[NULL @ 0000000002fa2cc0] start time for stream 1 is not set in estimate_timings_from_pts
[mpegts @ 0000000002fa02c0] Could not find codec parameters for stream 1 (Audio: aac ([15][0][0][0]
/ 0x000F), 0 channels, fltp): unspecified sample rate
Consider increasing the value for the 'analyzeduration' and 'probesize' options

but the file open and play fine.

I know that they are 10 bits videos but when mux in .mkv or .mp4 they open and play ( very slow) using ff-hevc ( instead of ff-hevc-vaapi for hevc 8bits ).
Only .ts container doesn't open
