Help needed for decoding of a H264 stream...

[Guetcho Guetchev]

Hello guys.
I constructed a transmission pipeline. Although I can play it with Quicktime (Mac OS, Windows) and Totem (Ubuntu, Debian) I am unable to decode that stream with the following pipelines:

/usr/local/bin/gst-launch-1.0 rtspsrc location=rtsp://bbs.darktech.org:1935/live/iphone.sdp ! capsfilter name=c1 caps=application/x-rtp,media=video,payload=97,clock-rate=90000,encoding-name=H264 ! rtph264depay ! h264parse ! capsfilter name=c2 caps=video/x-h264,alignment=au ! avdec_h264 ! capsfilter name=c3 caps=video/x-raw,format=I420 ! avenc_tiff !  multifilesink location=./tiff_file_%05d

/usr/local/bin/gst-launch-1.0 rtspsrc location=rtsp://bbs.darktech.org:1935/live/iphone.sdp ! capsfilter name=c1 caps=application/x-rtp,media=video,payload=97,clock-rate=90000,encoding-name=H264 ! rtph264depay ! avdec_h264 ! avenc_tiff ! multifilesink location=./tiff_file_%05d

At both of the pipelines I observe the following results:

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...

And no valid tiff files are produced.

The same behaviour is seen even if I replace all the elements after avdec_h264 (excluding it) with fakesink.


Please, can anyone point me what I am doing wrong?

REMARKS:

The used version of gstreamer is 1.0.5
To start the stream, use the executable built on the code stored here: https://github.com/ggetchev/gst_test

The actual C-file that runs the transmission pipeline is named gsttest2.c

Just execute make and run the executable in that manner:

./gsttest  <file> --no-reception
Where <file> is the un-bzip2-ed file 1.movie.bz2 from the git repository mentioned above.
