I have yet to try MythTV, but I am working on a pretty large video streaming/archiving project at work that may have use of it. We encode & archive all of our state legislature's General Assembly including committee meetings and House/Senate chambers, and one thing I could really use is the ability to cut out large chunks of SMPTE color bars. We a couple of direct broadcast signals that we encode from that are color bars when nothing is actually airing.<BR>
<BR>
For example, we know a meeting is supposed to start at 10:00am, but policitians are on their own time, so meetings typically start fifteen minutes or so late. That means, I usually have fifteen minutes of color bars (no audio tone) preceeding the actual meeting that I have to go back and trim off. Plus, with our current setup (which uses RealNetwork's line of software and some Perl scripts I wrote), we have to tell our encoders when to stop. So we create an event for this meeting to encode from 10:00am to, say, 2:00pm. Often, the actual meeting lasts an hour or so, so we have about two and half hours of color bars on the tail end that we have to go back and trim off.<BR>
<BR>
As I said, we currently use RealProducer to encode stuff to RealVideo files for archival and streaming playback. But we are building out some new machines to encode to MPEG-2 files (and transcode to several formats) using WinTV PVR-250 cards and Linux. Woot!<BR>
<BR>
So my question: can MythTV look for and cut out color bars as it does for commercials between black frames?<BR>

Thanks,<BR>
