Hi/2.
@Dariusz Piatkowski
3. What's the value of '2D Acceleration' ?
"YES" on my machine
Then, your system should play a movie with 2D acceleration, that is, SNAP mode. Nevertheless, if it fails, your system or SNAP driver seem not to support 1080p with 2D acceleration. In order to verify this, how about other smaller clips than 1080p, such as 720p ?
@Pete
It seems smplayer must have the capability to switch video output mode if the selected mode fails.
I've found the reason. See `-vo' section of
https://mplayerhq.hu/DOCS/man/en/mplayer.1.html#VIDEO%20OUTPUT%20DRIVERS%20(MPLAYER%20ONLY).
If the list has a trailing ’,’ MPlayer will fall back on drivers not contained in the list.
SMPlayer calls MPlayer with a trailing comma(,) for vo. In this case, `-vo kva:snap,'.
That is, if kva:snap fails, then MPlayer tries other VOs. In this case, try first just `-vo kva' without any suboptions such as snap. Therefore, libkva tries to find proper modes automatically and decides to use VMAN mode. This is the feature of MPlayer not SMPlayer.
And I recommend to use `Default' or `kva(fast)' option in SMPlayer not kva(snap) et al to minimize any confusions.
Finally, for the trap I cannot reproduce here at all. If possible, provide a clip to test, please...
Thanks!
