vidioc_try_fmt:379: Unsupported format for destination.

[Mario Marietto]

Hello.

Have you ever seen the errors below inside the log of the 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 players),the video
proceeds in spurts.

Thanks.
