Comment:
This is good, thanks!
It turns out that in dtvrecorder.cpp, the REC_STARTED_WRITING event is
only sent when it explicitly notes the first keyframe. By default, the
recorder ignores everything before the first keyframe, to avoid displaying
garbage at the beginning of playback, and so that the seektable frame
numbering is accurate.
It may be that your recorder is configured to disable the first-keyframe
check, or that it is using the NuppelVideoRecorder class which may be
using a different approach altogether.
Could you provide a few more items?
1. What kind of tuner/recorder is it?
2. What is the mysql output of "select * from capturecard;" (and if there
are multiple cards, just point out which is the card in question in case
it's not obvious)
3. Similar log file, but this time from "mythbackend -v network,record"
