[yocto] Help-Gstreamer Vaapi Plugin Issue in 1080p mp4 playback

[Meenakumari Shedole]

Hi All.

By using all latest version packages, Vaapi able to set the foreign window but there is random changes between Application and VaapiSink in SetWindowId, Play and Stop state.
 
Below are few of the different behaviors.

a.  To play 1080p media, First SetWindowID, Play and Stop. ( It works with foreign window)
b.  To play 1080p media, Second time only Play and Stop. (It won't work) and crash the daemon.
c.  start the daemon and app
d.  This time again SetWindowID, Play and Stop. (It works with foreign window)
e.  Only Play and Stop.( it works and won't crash the daemon also)
f.   Next time again setWindowID, Play and Stop. (it won't works)
g.  Next again to SetWindowID, Play and Stop.(it works)

Some times when I use only Play and Stop it open it's own window and start to play.

Regards

Thanks for your resposne Gwenole.

I downloaded updated gstreamer-vaapi-0.5.8 and GStreamer-0.10.36 with other dependency plaugins and va deriver but after manually install no luck to execute vaapisink.

can you please suggest, vaapi dependencies and their version to build.

Regards
Meena.

Hi,

The version you mention looks very old. I have integrated a fix from another user, who has been successfully using gstreamer-vaapi with GStreamer 0.10 in a scenario you describe (vaapisink + foreign window). Please update your gstreamer-vaapi version to at least 0.5.8. Or, the current git master tree. Other branches are not maintained any more. The fix I have in mind was f8666e2.

Regards,
Gwenole.
