Well, if nothing else, mplayer dumps out these parameters (well, not the bandwidth) when you play a video file, and you can use mplayer directly on /dev/video devices, though it doesn't de-mux atsc multi-streams. ATSC channels in theory all run about 19 megabits but the sub-channels of course are different and I presume that's what you are looking for when you want to know bandwidth? What would be nicer than the above, if anybody has seen it, would be a perl library or similar to extract these parameters from mpeg-ts files. ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Alan, I believe that the mythbackend log tells you the resolution of a channel when you switch to that channel. Try this: 1. Start mythbackend 2. # tail -f /var/log/mythtv/mythbackend.log 3. Run mythfrontend, watch live TV and change channels 4. Watch the output of 2 for the resolution of a channel as you switch to it Lane -- Meetup with other Myth users! http://mythtv.info/moin.cgi/MUG ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
[mythtv-users] app for determine HD resolution?
Does anybody know of an app which will do any or all of: * Show the resolution (H x V or 480p, 720p, 1080i, 1080p, etc.) of a specified dvb channel (ATSC) * Show the resolution of a specified .nuv file? * Show the bandwidth (bps) of a given ATSC channel I'm trying to determine just what my system can playback without stutter. It seems to do OK on some HD content, but not others, and I suspect the difference is either the format of the channel or possibly the number of subchannels (ie. the total bandwidth) on a channel.
