3D (stereoscopic) titles can have multiple video streams (LE, RE) although some 
are side-by-side (SBS) or some other form of anamorphic or interlaced 
presentation.

drawtext on aspect 4:3 are correct but drawtext on aspect 16:9 are
stretched.

thx for help ...

[FFmpeg-user] FFmpeg get stuck when using Intel QSV based encoders

2016-05-14 Thread Gianluca Cannata 

Good morning,

I wanted to try the FFmpeg QSV based encoders so I setup what is written 
here: https://trac.ffmpeg.org/wiki/HWAccelIntro#IntelQSV for Linux systems.


I'm running Manjaro Linux 16.06-pre3 on an Intel(R) Core(TM) i7-4770 CPU 
@ 3.40GHz processor.




This is what ffmpeg gives me:
