<br>
You can use ffmpeg + v4l2loopback to make a "virual" video device openable with gem...<br>
<br>
Here's an example of the command line :<br>
ffmpeg -i rtsp://<a href="http://10.0.0.69:1234//live1.sdp" target="_blank">10.0.0.69:1234//live1.<u></u>sdp</a> -pix_fmt yuv420p -an -r 25 -f v4l2 /dev/video69<br>
<br>
(http and rtmp work too)<br>
<br>
But ffmpeg must be built with the v4l2loopback backend.<br>
The static one here works : <a href="http://ffmpeg.gusari.org/static" target="_blank">http://ffmpeg.gusari.org/<u></u>static</a> (unreachable right now... :-/ )<br>
<br>
Here's some documentations, but it's in french, sorry :<br>

Goodluck...<br>

Hi list,<br>
<br>
I want to get web camera streams into Gem, with different streaming<br>
formats (mainly http and rtmp). VLC plugin seems like the perfect way<br>
to handle that, but I can't get it to work with Gem.<br>
I know pdgst could be a solution but vlc has the advantage that I<br>
could handle any stream type the same way (where gst needs a different<br>
pipe).<br>
<br>
On Mint17 and Ubuntu 14.04 Gem crashes with segfault as soon as I try<br>
to open anything with VLC (like |driver vlc, screen://( )<br>
Both use vlc 2.1.4, I also tried 2.1.6 (vlc stable-daily ppa), same<br>
behaviour.<br></span>
Having seen this thread [1], I tried the symlink removal without<span class=""><br>
success, so made a gdb backtrace (attached with this message, usefull<br>
information are in the last lines)<br>
Config for this backtrace is :<br>
Freshly installed, updated Ubuntu 14.04.1<br>
VLC 2.1.4<br>
pd-extended 0.43.4<br>
Gem 0.93.git 374f713 freshly compiled<br>
<br>
I had success regarding VLC and Gem on Ubuntu 13.10, which uses vlc<br>
2.0.8. But with that vlc version, my stream is really long to start<br>
and stops after one minute or so. VLC behaviour between 2.0.8 and<br>
2.1.4 regarding rtmp looks very different, in vlc 2.1.x changelog they<br>
say "New RTMP input module, using libavformat!", which might explain<br>
that (seems that it was ffmpeg before).<br>
<br>
Has anyone successfully compiled vlc plugin for gem with recent vlc<br>
version ? Or any idea what other solution I could try ?<br>
