vidioc_try_fmt:379: Unsupported format for destination.

Hello my friend.

Have you ever seen this error inside the log of your ARM Chromebook model XE303C12 ?

[ 2416.631903] vidioc_try_fmt:379: Unsupported format for destination.

I'm not sure but they could be correlated with the warnings I get when I try to watch an mp4 file using SMPlayer :

libEGL warning : egl failed to create dri2 screen
libEGL warning : failed to get driver name for fd -1
libEGL warning : MESA-LOADER : failed to retrieve device informations

I'm looking for the technical reason why,when I play an mp4 video with VLC or SMplayer (and for sure other multimedia player),the video proceeds in spurts.

This is probably because the processor does not have enough performance for software rendering, and the mesa is not patched to partially support acceleration or its version does not allow it.
