I've build the latest ffmpeg & vaapi drivers etc on my ubuntu 16.04 following the gist here

 

During playback, ffmpeg is failing with:

I also tried to use the default ffmpeg version, which comes with the latest package version. 

this causes ffmpeg to load the whole media file parses it. 

the video starts then 2-5min later (depending on the video size..)

 

any idea?

all files?  I've seen this in the past on certain media, but not on all.

looks like it's only with the subtitle Codec: SUBRIP 

 

PGSSUB and SRT are working fine
