[gst-devel] Elphel & rtpjpegdepay

[Florent]

Hi,

I am trying to test the new rtpjpegdepay plugin with an Elphel 353
camera. When i try to decode the stream using jpegdec, i get this
error:
0:00:00.168944847 12994  0x80a9240 WARN       rtpjitterbuffer
rtpjitterbuffer.c:197:calculate_skew: Clock rate changed from
4294967295 to 90000

gstjpegdec.c:1042:gst_jpeg_dec_chain:<jpegdec0> error: Error #69:

If anyone is wanting to take a look at the files, i took the liberty
of uploading dumps and logs:

GST_DEBUG=3 gst-launch rtspsrc location=rtsp://192.168.1.9:554
debug=true ! filesink location=~/src/elphel/rtpdump.mjpeg 2&>

GST_DEBUG=3 gst-launch rtspsrc location=rtsp://192.168.1.9:554
debug=true ! rtpjpegdepay ! filesink location=~/src/elphel/dump.mjpeg
2&> dump.log
https://flowty-public-dev.s3.amazonaws.com/elphel/dump.log
https://flowty-public-dev.s3.amazonaws.com/elphel/dump.mjpeg

Strangely enough, i cannot decode the dump.mjpeg even with mplayer.
Should i assume that the rtpjpegdepay is not depacketizing properly ?

Thanks for any hint; it would be cool to use elphel cameras with gstreamer !
