Re: [Linphone-developers] How to use H.264 Encoder in mediastreamer2

[曹贵林]

Hi Guy,

I find the answer for my question. Here is the solution: 

________________________________________________

1) Install libx264 >

$ sudo apt-get install libx264-dev

2) download msx264 plugin from LinPhone website:  >

http://download.savannah.gnu.org/releases/linphone/plugins/sources/

3) build msx264 and install: >

$ ./autogen.sh

$ ./configure

$ make

$ make install

4) Now, your (previously-built) applications can use H.264 encoder! 

No need to re-build linphone, mediastreamer2;

No need to re-build your application;  e.g 

$ cd mediastreamer2/tools

$ ./mediastream --local 7701 --remote 192.168.7.40:7701 --payload 102 --bitrate 10241024

NOTE: the performance of H.264 payload is not good. Hope someone tell me why?

Hi Ghislain,

Thanks for your reply.

I have download and build msx264 plugin and x264 encoder. But I can not find any instructions about how to use this plugin in mediastreamer2.

Would you please tell how to use it? Thanks!

Hi,

You need the msx264 plugin. See https://www.linphone.org/eng/download/

Cheers,

Hi Buddies,

Build Env:

Ubuntu 12.04 32-bit / Linphone 3.7

I am trying to embed VoIP into my current working applicaiton.

I build linphone on Ubuntu 12.04, and run mediastreamer2/tools/mediastream. If

I specify playlaod type as 102, which means H264, the program says such error:

  No encoder available for payload 102:H264.

I go into the source code of mediastreamer2 and find all video encoder

MSFilterDesc objects are created in mediastreamer2/src/videofilters/videoenc.c

But there is no enoder filter for H264.  And I checked header file

mediastreamer2/include/mediastreamer2/allfilters.h, there is no ID defined for

H264 encoder.

Does anybody tell me how to use H264 encoder in mediastreamer2?

Thanks!
