[linux-dvb] Re: Green flicker when capturing via v4l interface

["Edward Wildgoose" <Ed@Wildgooses.com>]

I have no idea what the green flickers are, but they seem to be related to
when the load on the machine is higher...  Probably something to do with
missing or lost data packets I should think.

What about capturing from the mpeg stream and using transcode or something
else to give you the mpeg stream you want.  dvbstream can also broadcast the
channel to other machines quite easily if that is what you want?
