Re: [mythtv-users] cut commercials only, no transcoding
Being totally ignorant, and one who badly wants this feature forMPEG4->MPEG4, I'll ask some simple questions (just in case I try to learn enough about myth and MPEG4 to make some haphazardattempt to work on the MPEG4 case):1) Are there any plans for this feature for MPEG4->MPEG4? MPEG4->MPEG4 cutting has been in since at least 0.14. Unfortunately it is broken in 0.18.1, but I just read that it will work again in 0.19.

I think the consensus is that there is no consensus :) It basically comes down to -> Use what works best for you. Take your pick.

It only applies to MPEG2 -- I think MPEG-4 incorporates that functionality into the file. I can't answer what exactly it is besides the guess that it keeps track of the key frames so fast forwarding and rewind results in clear pictures instead of pixel blobs upon unrelated frames (just my guess based on my experience -- I don't know the file formats but nobody else has replied to that query). ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Yeah, a movie on the weekend got flagged for 10 ads, however then another show didnt get flagged much at all.

I've played around some, trying to figure out my transcoding problems. A MPEG4 recording seeks fine in mythfrontend, even if I go in and manually remove all the entries in the recordedmarkup table. Is the recordemarkup table only for MPEG2 and/or RTJPEG? I assume a mythtv/MPEG4 has enough seek infomation in the header? On the other a broken transcoded MPEG4 recording doesn't seek even if I do mythcommflag --rebuild -f . Thanks, Steve __ Do You Yahoo!? Tired of spam? Yahoo!

Re: [mythtv-users] cut commercials only, no transcoding
There is a commercial_cut program available which can read the cutlist from the myth database and do a good job for removing the commercials. I use that regulary to remove commercials from my HD programs. Its a 3 step process. Run mythcommflag to find the detect commercials. Then run mythcommflag -gencutlist to load the cutlist. And then, run commercial_cut to remove the commercial. I do this all from a single script without actually looking/editing the commercial points. I trust mythcommflag is doing very good job and I do detect almost all the commercials. Only one time, it deleted everything of the "Lost" episode after the first commercial.
