Hey all<br><br>I'm trying to write a pipeline that will take video in from a network source, do some transcoding, and send it out to a network sink. No problem there. But I need to be able to get preview snapshots of the stream as its running, either on demand, or just have it continuously dump out frames to a known file periodically. I'm doing some experiments using a v4lsrc and xvimagesink as my fake network source and sink for now. I've found the 'tee' block that looks promising to split my stream into 2, so one can go on its way to the network sink, and the other could maybe write to a file, but all my experiments have only shown me a single frame in my xvimagesink. Am I going down the right path trying to use 'tee' or is there some other set of blocks I should use?<br>
<br>Thanks<br>
