<br>
Has anyone attempted or found a way to transcode a DVTS stream directly off of
receiving it via multicast? My goal is to be able to transcode DVTS streams to
different formats and resend them as Access Grid-based or web-based streams. So
far, it looks like the only way to do it would be to modify xdvshow or one of
the other DVTS apps to hook together with ffmpeg for transcoding & ffserver
for streaming, since as far as I can tell, apps like ffmpeg or VLC can't
receive DVTS by themselves. Before I go spending a bunch of time on that I want
to make sure this hasn't already been done some other way.<br>
<br>
Thanks,<br>
