Hi shalini,
As to my experience U should set the path for the FFMPEG.
U must use this command.
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig.
if u r trying to compile linphone for PC.
I want to know whether you are compiling linphone for PC,or
cross-compiling for PowerPC or ARM processor.
This would help to give u a correct solutions.
try the above command if u r compiling for PC.
Regards
Cheluva

Thanks Simon.
That really worked. I'm incrementing it by 900. Worked great.

It's surely the timestamp you are asking that is incrementing to slowly.
For video payloads the clock rate is usually 90000.

Hi Simon,
There is a problem with the video error recovery. Whenever there
is
a loss in the network packet or loss in the sequence number what is the
best
way to get from the ortp layer? Since if there is a loss, i need to inform
the other end to send another IFrame. The video is displayed based upon
the
incremental data received. If the part data is lost then further data
received is meaningless.
I want to inform the loss of info and requesting the IFrame
through
rtcp. Can you please help to solve the problem. Thanks.
Regards,
Kannaiyan

Hi All,
I am very new to linphone.
I have linphone-1.6.0 version.
I have downloaded speex, readline, libtheora and other libraries
required.
While configuring it, I am getting the following error.
------------------------------------------------------------X-----------
----------X-------------------------------------------------------------

checking for FFMPEG... Package libavcodec was not found in the
pkg-config search path.
Perhaps you should add the directory containing `libavcodec.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libavcodec' found

I tried after installing ffmpeg-0.4.9-pre1 from source, but even then I
am getting the same configuration error.
Also, can you please tell me the exact commands to configure.....flags
and all.
Thanks in Advance

Shalini
