Hello Sylvain,

Thank you for your answer. Indeed that error messages about MSVp8Dec (msh263dec, ... depending on what codec we're trying to use) are outliers (perhaps they are attempts to use some hw decoder?...) and do not prevent Linphone of working properly.

I was trying to use directmedia and/or directrtpsetup in my Asterisk config but to I found out that Linphone has problems(?) using this setup. When I switched it off forcing RTP streams to go through Asterisk it started to work.

Do you know if it's possible to have direct RTP communications between Linphone terminals using just Asterisk for the signaling?

TIA,
Nuno

Hi Nuno,

I checked the logs and there is no error, however you don't receive any audio or video.
So my guess is there is an issue with your network. Try to enable ICE.

Cheers.

Hello,

I currently testing Linphone in an Softwinner Esmart 7'' - specs here http://specdevice.com/showspec.php?id=ea62-d568-0033-c5870033c587

The device is transmitting audio and video correctly but is unable to process/reproduce incoming RTP streams. In terms of video I tested with codecs VP8 and H263. Looked at logcat when using VP8 and found "no such method on filter MSVp8Dec".

I tested with different apps and audio in and out is working fine with them.

Indeed Google Play Store says that Linphone is not compatible with this device, but I don't know why.  Does anyone know why?

Is there something like a HCL or minimum system requirements to run Linphone in Android?

TIA,
Nuno
