[Linphone-users] Incoming Video on Raspberry Pi

[Logan, Timothy]

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:

 

INFO:root:Video configuration set: bitrate=300000bits/s, fps=10.000000, vsize=352x288 for encoder [0x25ccf80]

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,
