Raspberry pi hardware accelerated playback

[Damien Picard]

Thank you ! So I see that I don't use the zerocopy while encoding too :

/GstPipeline:pipeline0/GstOMXH264Enc-omxh264enc:omxh264enc-omxh264enc0.GstPad:sink:
caps = video/x-raw, format=(string)I420, width=(int)1920, height=(int)1080,
interlace-mode=(string)progressive, pixel-aspect-ratio=(fraction)1/1,
chroma-site=(string)mpeg2, colorimetry=(string)1:4:0:0,
framerate=(fraction)30/1

I should have
/GstPipeline:pipeline0/GstOMXH264Enc-omxh264enc:omxh264enc-omxh264enc0.GstPad:sink:
caps = video/x-raw*(memory:GLMemory)*, format=(string)I420,
width=(int)1920, height=(int)1080, interlace-mode=(string)progressive,
pixel-aspect-ratio=(fraction)1/1, chroma-site=(string)mpeg2,
colorimetry=(string)1:4:0:0, framerate=(fraction)30/1

(Sorry to pollute the thread)
