Accelerated gstreamer and QML
Posted: Wed Mar 27, 2013 10:10 am
Hi everyone, I'm not working on the rpi right now, but I'm posting here because I've a very similar system and this forums seems to be the only one that could help me.
I've a board with gstreamer hw accelerated provided from nvidia, I can launch video with the following command: and it works.
And I've succesfully compiled and installed QT5 (5.0.1) with QtMultimedia.
I'm writing now a very basic qml sample to test the video capabilities:
but this code don't work because of some wrong command passed to gstreamer...
And that's true, I don't have autoaudiosink element, but I've nv_omx_videosink and nv_omx_audiosink.
Do you have some tips?
Thank you.
