Hi everyone,<br>
<br>
I am having trouble getting the gstreamer command line previously
discussed in this list to work to convert h.263 video for Asterisk usage. If
someone could provide the gstreamer versions that worked for them so I could
downgrade that would be greatly appreciated. Or, if you have further insight
into how I might resolve the issue with my current setup, that would be
apprecited substantially more.<br>
<br>
This is my version of the command line:<br>
gst-launch-0.10 filesrc location=departments.mov ! qtdemux name=demux !
ffdec_h263 ! videoscale ! video/x-raw-yuv,width=352,height=288 ! ffenc_h263
rtp-payload-size=512 ! rtph263pay ! asteriskh263 ! filesink location=
departments.h263 demux. ! queue ! ffdec_adpcm_ima_qt ! audioconvert !
audioresample ! audio/x-raw-int,rate=8000,channels=1 ! wavenc ! filesink
location= departments.wav<br>
<br>
This gives the error:<br>
WARNING: erroneous pipeline: could not link rtph263pay0 to asteriskh2630<br>
<br>
Out of interest, i also tried rtph263ppay (two ps, h263+) and it worked in the
toolchain. However H.263+/RFC2429 won't work for me.<br>
<br>
I am running on Fedora Core 5. I installed the gstreamer-universe from
the gstreamer repos.<o:p></o:p></span></font></p>

PS: I tried ffasterisk but it does strange things with the timestamps, and I
much prefer the flexibility that should come with gstreamer.<o:p></o:p></span></font></p>
