OMAP performance verification

Other Parts Discussed in Thread: OMAP3530

Can someone suggest a gstreamer pipeline that would allow me to verify my OMAP3530 board can encode 720x480 NTSC video in realtime?

Thanks.

There are these examples from our gstreamer wiki page for H.264 and MPEG4:

gst-launch -v videotestsrc num-buffers=2000 ! TIVidenc1 codecName=h264enc engineName=codecServer ! filesink location=sample.264

gst-launch -v videotestsrc num-buffers=2000 ! TIVidenc1 codecName=mpeg4enc engineName=codecServer ! filesink location=sample.m4v

I think the problem with those are they are going to default to 320x240 size. You can insert caps to force videotestsrc to go 720x480, but then it eats up all your cpu. (It would be nice to have a dsp accellerated videotestsrc!)

Are you using the TI DMAI plugin with gstreamer? That will enable DSP acceleration.

Yes, I'm using the TI gstreamer plug in, but it doesn't use the DSP for non-TI elements like videotestsrc. I'm using someone smart could write something like a dmai-videotestsrc which uses the dsp to generate video.
