I am writing a simple application that uses Gstreamer to watch DVB-T.
The pipeline works as expected, but I am not able to tune to a new
channel. What i am currently doing is the following:
dvbbasebin name=dvbsrc ! mpegtsdemux name=demux ! queue
max-size-buffers=0 max-size-time=0 ! mpeg2dec ! deinterlace !
xvimagesink force-aspect-ratio=true name=video demux. ! queue
max-size-buffers=0 max-size-time=0 ! mad ! pulsesink
1. Set the pipeline to STATE_PAUSE
2. Set all relevant parameters of dvbbasebin (frequency, bandwith,...)
3. Set the pipeline to STATE_PLAYING
The error I am getting is always "Internal data flow error".
What is the reccomended way to change the tuning parameters in order
for the pipeline to keep working after the parameters are set?
