Hi,

Thank you for sending time with me 

But it didn't work :(

Case 1 : 

I checkout latest version linphone for android from git (3.2.6) and followed steps in wiki

I built with option :

./prepare.py -DENABLE_NON_FREE_CODECS=1 -DENABLE_OPENH264=1 (Built OK)

When I run app on Android 4.4 (API 19). The linphone asks me to download OpenH264. It was perfect 

But when Linphone restart after downloaded OpenH264 then I got some logs :

 LinphoneCoreFactoryImpl Loading OpenH264 downloaded plugin:/data/data/org.linphone/files/libopenh264.so

The libopenH264.so has loaded and libmsopenh264.so couldn't load

I guess these errors maybe come from on target  SDK 19 

Case 2:

I download Linphone from PlayStore ( version 3.2.5) 

These are logs when I run linphone

Are there some different between build 3.2.5 and 3.2.6 ?

I checked Makefile : The Makefile in 3.2.5 is different 3.2.6

I think that is a bug when build linphone sdk 3.2.6 on Android

Thank you for reading my mail

Hello,

To use OpenH264 codec you had two choices.

Build Linphone with this options:

./prepare.py -DENABLE_NON_FREE_CODECS=1 -DENABLE_OPENH264=1 -DENABLE_EMBEDDED_OPENH264=1

It will enable OpenH264 and embed the codec.

Or you can build Linphone with this options:

./prepare.py -DENABLE_NON_FREE_CODECS=1 -DENABLE_OPENH264=1

It will enable OpenH264 and if your system is Android < 5.0, you can download it from the app in options video and click on H264 codecs.

Hi everybody!!!!

Im trying to run linphone on Android 4.4 (API 19) (Linphone 3.2.6)

I want to use codec OpenH264 for video call.

I built linphone with two options DENABLE_OPENH264=ON -DENABLE_NON_FREE_CODECS=ON, and downloaded libmsopenh264.so from cisco too.

But when I run app , I always get error 

 Fail to load plugin /data/app-lib/xxxxx/libmsopenh264.so : dlopen failed: cannot locate symbol "ortp_logv" referenced by "libmsopenh264.so"...
