Hi I am trying to decide if it is feasible to let FS do transcoding between different H264 formats for live video calls. This is because I've got SIP clients that both use H264 but with different formats and one (with a bad H264 decoder) has problems decoding H264 stream from the other. But each of these two clients communicate fine using H264 with a third client that uses ffmpeg. I'm thinking of adding a module which uses ffmpeg, so that it will transcode H264 between different parameters. I've got a few questions: 1. Is this feasible? I'm not looking at supporting many simultaneous calls. 2. What is involved in transcoding real-time video stream? 3. Anyone's done anything like this before? I'm new to FS and any suggestions would be very much appreciated! Yufei
Is it possible sure... Is ot probably to happen anytime soon? Not until the patents run out... On 7/26/12 5:04 PM, "yufei.tao" <yufei.tao@redembedded.com> wrote:

x264's license is incompatible with FreeSWITCH. As it stands for now, GPL is incompatible with MPL. On Thu, Jul 26, 2012 at 5:45 PM, Terry Barnum <terry@digital-outpost.com> wrote:

we can not and will not use GPL software, the license is not compatible with the GPL and would polute the codebase with additional restrictions that are not wanted or needed. now if someone could get them to change the license or atleast give us a license under better terms such as the LGPL or the MPL then the license issue would be null Ken Sent from my iPad On Jul 26, 2012, at 7:45 PM, Terry Barnum <terry@digital-outpost.com> wrote:

you would probably need to do something like make a mod for ffmpeg that protects you from the gpl then allow the user to build that lib on his own and choose at compile time to install patented or adverse licensed components. No license rules prohibit an end user from combining code only distributors. but even then we need a bunch of code to write.

I patched libvlc and it can now decode any video vlc supported and encode with x264 and send to any sip phone. Specifically I'm trying to use it to play a 1080p stream and resize to CIF or D1 so a video phone will accept(Sending 1080p will cause some phones to reboot :( ). Still need a lot of code to make it working neatly, however, I might can do a demo on ClueCon and @William if you'd like to review the code and merge into tree I'll happy to contribute that later.

you would probably need to do something like make a mod for ffmpeg that protects you from the gpl then allow the user to build that lib on his own and choose at compile time to install patented or adverse licensed components. No license rules prohibit an end user from combining code only distributors. but even then we need a bunch of code to write.

I patched libvlc and it can now decode any video vlc supported and encode with x264 and send to any sip phone. Specifically I'm trying to use it to play a 1080p stream and resize to CIF or D1 so a video phone will accept(Sending 1080p will cause some phones to reboot :( ).
Still need a lot of code to make it working neatly, however, I might can do a demo on ClueCon and @William if you'd like to review the code and merge into tree I'll happy to contribute that later.

In none of the LGPL packages of libvlc is ffmpeg enabled, but there is a module for libvlc for ffmpeg. http://wiki.videolan.org/FFmpeg
