I am developing VOIP app using linphone IOS/Android library.
Basically I used OpenH264 video codec.
When call is answered, both side saw black screen.
After long time, both size can see the video each other.
When I see the log, there are many packets loss so that First frame can not be decoded.
At LinphoneCallStreamsRunning, I called FIR (linphone_call_send_vfu_request) request but not helped.
Is there any config for OpenH264 video codec?
I want to see the video as soon as accept call.
Thank you.

5.Change ffmpeg-priv.h file if you used latest ffmpeg source code.
linphone-iphone/submodules/mediastreamer2/src/utils/ffmpeg-priv.h
Add following code.
#define HAVE_FUN_avcodec_encode_video2 1
#define HAVE_FUN_avcodec_get_context_defaults3 1
#define HAVE_FUN_avcodec_open2 1
Run prepare.py and make

IMPORTANT
This build will not work on x64, only work on armv7-a.
If there is exist any issue, please let me know.
Thank you.
