[Asterisk-video] Asterisk video conversion GStreamer issues

[Barry Kendell]

Hi everyone,

 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.

This is my version of the command line:
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

This gives the error:
WARNING: erroneous pipeline: could not link rtph263pay0 to asteriskh2630

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.

 I am running on Fedora Core 5. I installed the gstreamer-universe from the gstreamer repos.

gstreamer.i386                           0.10.10-0.gst.1.5      installed

gstreamer-python.i386                    0.10.5-0.gst.1.5       installed       
gstreamer-tools.i386                     0.10.10-0.gst.1.5      installed       
gstreamer-universe.i386                  0.10.1-0.gst.1.5       installed       I have not looked into the gstreamer source just yet, but will do that if I can't resolve this problem otherwise.

Thankyou in advance for any help you could offer,
Barry


PS: I tried ffasterisk but it does strange things with the timestamps, and I much prefer the flexibility that should come with gstreamer.
