Ämne: Re: [Iaxclient-devel] Iaxclinet and H264
Hi Edouard,
As far as I know, x264 is just an encoder. You also need a decoder
if you want to use H.264 video.
There are two issues with using x264 in iaxclient.
1. x264 is GPL and iaxclient is LGPL. This prevents us from
incorporating the codec in the iaxclient sources. What we could do is
create a wrapper and then if anybody wants to use x264 can simply
drop the sources in place and build (and work under the rules of
GPL). This is similar to what we do for the VSS H.264 codec.
2. There is such a wrapper for ffmpeg. This is actually a better
solution because ffmpeg comes with a H.264 decoder and also can work
with x264. In addition to that, it supports a bunch of other codecs,
like H.263/261. However, this wrapper DOES NOT WORK at this moment.
We are changing the video codec API these days, and all the codecs
will need to be updated. We plan to update the Theora and VSS codecs
and then, if time allows, the ffmpeg wrapper. I'll send an
announcement to the list when the API is stabilized, so if anybody
who wants to work on the ffmpeg wrapper, please wait until you see
that.
