omxh264enc does not receive parameters

Fri Feb 10, 2017 11:45 am

Hi all,

I'm trying to optimize a GStreamer pipeline taking video from usb webcam and streaming it on RTP/H264.

I can correctly stream the video using omxh264enc, but I cannot set any parameters (i.e. target-bitrate) since it causes the pipeline to crash. Any idea?

The SisOp is the latest downloadable Noob and it is updated to latest online "dist-upgrade".

Thank you
walter

I'm suing something like this:

Code: Select all

! omxh264enc target-bitrate=1153432 control-rate=variable ! video/x-h264,stream-format=byte-stream,profile=high,width=910,height=512,framerate=50/1 !  h264parse ! queue !

Are you using omx plugin from apt-get or have you compiled it?
