Re: [Linphone-developers] liblinpone H264, again

Oh my goodness! That was it!  After a week and half of struggling, using the wrong version of openh264 was the last thing.  Thank you so much Ghisian for your help.  I was about to give up…

To briefly summerize all the obstacles I had to overcome to get this working, in hope of giving some pointers to other people:

1.  Always turn on debug and inspect the log output carefully.

2.  Find out what and where linphone is trying to load.  Make sure the openh264 library is at the right place and that liblinphone can find it.  Look for something like the following.  There could be lots of reasons that h264 is not loaded, ranging from not being able to find the plugin directory, to incorrect file names, to wrong dylib names.

  Reason: image not found



3. on OS X, use tool and install_name_tool to make sure everything is matched correctly

4. And of course, use the version of openh264 that media stream 2 supports.  If everything is loaded, but H264 still does not work, you may be using a incorrect version.

5. Finally, don’t give up, openH264 does work with liblinphone.  :)



Thanks again, everyone.  

Cynthia

Hi Cynthia,

It looks like you are using an openh264 library that is newer than the version 1.5.0 for which the msopenh264 mediastreamer2 plugin is designed. Maybe you build it from source? Either build the version 1.5.0 or use a version distributed by Cisco.
Regarding your licensing question, the H.264 license is handled by MPEGLA. Take a look at http://www.mpegla.com/main/programs/AVC/Pages/Intro.aspx

Cheers,
Ghislain

Hello,

I managed to get open H264 loaded. SIP hand shake all seems well.  Now the error I am getting is much more cryptic to me (see below).  I am not sure what uiSliceMode is and how I can change its value.  Any ideas?

[OpenH264] this = 0x0x60000004cea0, Error:ParamValidationExt(), invalid uiSliceMode (4) settings!
[OpenH264] this = 0x0x60000004cea0, Error:WelsInitEncoderExt(), ParamValidationExt failed return 2.

Thanks for any help you can offer!
