Got it fixxed.

Use gst-launch instead of gst-launch-0.10

Weird bug though...

Hi all,

which vlc version are you using. Mine (1.01 qt-version under debian) seems not to interpret the sdp file correctly.

When I start vlc, streaming starts on the n900 (as observerd with wireshark on the linux box). But after around 100 packets the tcp window size goes to 0 (I think because of full buffer on vlc side) and the n900 sends no more packages.

I also tried mplayer sdp://file.sdp. Streaming also starts from the n900 and doesn't stop, but mplayer cannot recognize the frame rate and exits. But now the n900 stream does not stop!

Thanks in advance for any suggestions

Hello again,

tested with vlc under Windows XP/SP2 with vlc 1.1.4. Doesn't work either.

Did anyone get mp4mux/qtmux to work on N900? They don't exist on mine and so I can only write a raw h264 stream to the memory (I save and stream simultaneously using tee and queue in case of connection errors) but can't mux it directly to an mp4 file.

Code:
Nokia-N900:~# gst-launch-0.10 v4l2src device=/dev/video0 ! dsph264enc ! rtph264pay ! udpsink host=78.21.100.x port=5434
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
create_node: dsp node create failed
sink_setcaps: dsp node creation failed
It cannot use DSP for some reason.
I had the same. System log also got this:
Code:
Jan 13 00:25:18 Nokia-N900 gst-launch-0.10: dsph264enc0: dsp node allocate failed
Jan 13 00:25:18 Nokia-N900 gst-launch-0.10: dsph264enc0: dsp node creation failed
