One-Way Video - Send Only

[Taylor Prins <tprins@xxxxxxxxxxxx>]

I cannot seem to get one-way video to work with pjsip.  I’m using 2.7.2.  The camera I have is using the mxc_v4l2 driver and can be seen by v4l2-ctl but in pjsip, it shows up as no supported formats.  A few things are happening:

 

1. I have vid_in_auto_show = PJ_FALSE but yet the sdp that gets generated in a call always has the video set for sendrecv
2. Because of #1, if I attempt a call, the device always fails during the ‘Setting up RX’ state as I have no rendering device
3. If I try to use the vid_streamutil that is bundled with the samples, I get an error stating “Device has no supported format: Unknown error from video driver (PJMEDIA_EVID_SYSERR)”

 

Anyone have any ideas?
