Part Number:TDA2PXEVM
Tool/software: Linux
Hi,
Per the ticket https://e2e.ti.com/support/processors/f/791/t/778002, we have enabled gstreamer decode support on TDA device with vsdk 3.05. According to spec http://www.ti.com/processors/automotive-processors/tdax-adas-socs/applications/surround-view.html, TDA2x device can decode 4x 1Mp @ 30fps. But we cannot manage to decode 4 instances of 720P video stream simultaneously. I experiment as follows.
1. compile a script decode.sh for convenience.
while true;
do
gst-launch-1.0 filesrc location=test720p.avi ! decodebin ! videoconvert ! waylandsink
done
2. run several instances of decode.sh
$./decode.sh&
We cannot enable three or more gstreamer encoder instances simultaneously and the system outputs such errors.

Please help suggest what's wrong with it. Thanks!
