GStreamer-1.0 omxh264dec output color space format

[Lazar Todic]

Hi everyone. I'm trying to write simple video filter in GStreamer-1.0. My
filter is linked after omxh264dec. In order to access the wanted
pixels(bytes) in correct order in buffer I need to know what is the output
color space format of the *omxh264dec* decoder. I think I expressed myself
correctly, please don't mind if I'm wrong, I'm relatively new to GStreamer.
When launching *gst-inspect-1.0 omxh264dec* I see that source pad receives
video/x-raw. Does this mean that it supports any x-raw format, NV12, YUV420
etc? I need to work with data in *NV12* format. If I use this pipeline can I
expect that the color space format is NV12?

pipeline:
gst-launch-1.0 filesrc location=out.mpg ! tsdemux ! h264parse ! omxh264dec !
video/x-raw, format=NV12 ! videoconvert ! colorfilter ! nveglglessink -e

Thanks in advance!
