Re: [Linphone-users] Incoming Video on Raspberry Pi

Hello Timothy,

Don’t set this option to True. It asks the RPi linphone to display the video that it receives, which is not what you want.
You want the RPi to only send the video, not display the received one.

Just set these options:

    self.core.video_capture_enabled = True
    self.core.video_display_enabled = False

Hello all,

 

I saw that recently there was support added for a Python wrapper that enabled support for Raspberry PI. This is a feature that I was eagerly waiting for and have to thank those responsible for the feature.

 

For my project, I essentially want to make a "pet phone" where I can video chat a SIP client (hooked up to RPI) to "check up" on my dog while I am at work. After some playing around, I was able to take the security camera example and get it working with the SIP client I have on my iPhone. My problem arises when I want to enable incoming video on the Raspberry Pi. Everything seems to work well, until I enable the following line:

 

 self.core.video_display_enabled = True

 

With this enabled, I get the following error:

CRITICAL:root:No video display filter could be instantiated. Please check build-time configuration

 

Before I muck around too much in the source code, I wanted to see if there was actual support for this. I don't mind wading through source and recompiling if necessary- I just did not want to spin my wheels if this currently was not supported (or if enabling video was too much of a load for the RPI's ARM chip).

 

Thanks and Best Regards,
