How to decode RTP stream, display it then transcode it and save it to a file using gstreamer ?

Hi There,

We would like to decode an incoming RTP video stream, display it on a LCD display then transcode it and save it to a file. To me it seems like the best solution for this would be to use a video sink device which supports passing through the data. That way there is no need to duplicate the data (using "tee"). Is it possible to configure mfw_isink or mfw_v4lsink for something like this ? If not, would it be a herculean task to modify the plug-ins ?

Thanks,

/Otto

Hi Jamie,

Although I'd prefer to have a pass-through video sink, using "tee" appears to work but it burns about 30% CPU usage (presumably from all the buffer memcpy:s)

Thanks,
