Full HD with gst-omx on Raspberry Pi?

[Stuart Axon]

Hi,  I'm doing video playback with gst-omx on raspbian, and have (completely unscientifically) set my GPU memory to 256mb and everything seems to work OK.

386mb sounds like it should be fine.

1] Ahhh something wrong with your quote? .. I had set gpu_mem = 386 MB and
not 86 MB.. I think 386Mb should be sufficient for 720HD playback ? If not
kindly suggest me the value.
2] My bad about gst-omx versions, What I meant to say is I have tried both
the version of gst-omx 1.20 with gstreamer bundle 1.8.1  and gst-omx 1.9.90
with gstreamer bundle 1.9.90
