Hi list,
I usually record with lots of margin before and after. I also cut everything after detecting commercial breaks. This however has two small side effects. First, the start margin time will be taken for the recording name, so its a bit off, like 20:55 instead of 21:00. Second, after cutting, its not possible to see the actual start time of the recording any more. (This is sometimes useful to know to adjust the margins of repeated timers.)
Recently I had the idea, when cutting why not shift the recording start time to the time of the beginning cut mark? This would even have another positive side effect: That way its easy to cut a recording into two parts, because they would have different start times.
Well, why not, so today I tried and the result is attached as patch. Unfortunately, a small API change is necessary, so plugins should be re-compiled. I don't expect this to go into VDR soon, but maybe when development cycle starts again.
Cheers,
Udo
