I believe that I have a work around for my problems. Two things need to
be fixed:
The fps value that /usr/share/mythtv/mytharchive/scripts/mythburn.py
calculates is wrong. Sometimes it is the reciprocal of what it should be.
Sometimes it is double what it should be (for programmers listening it is
possible it was half the reciprocal since the fix I was running at the time
simply took the reciprocal of the fps value if the fps looked bad).
in the aforementioned mytyburn.py replace this code:
Code:
fps = video.attributes["fps"].value
return (videores, fps, aspect_ratio)
with this code:
Code:
#fps = video.attributes["fps"].value
"""cliff added this to fix bad fps value"""
"""fps is correct sometimes"""
"""fps is sometimes the reciprocal"""
"""fps is sometimes double or possibly half the reciprocal"""
"""fps may need to be 25.00 something else outside the USA"""
fps = 29.97
return (videores, fps, aspect_ratio)
The lines starting with """ are just comments. I put my name in there
so I could find the lines in the future.
I believe that the fps value is the fps of the display device that the DVD
will be played on, so PAL systems will probably need 25.00 or 23.976 or
some other strange value.
It appears that this bad fps value (when it is twice what it should be) is
what causes ffmpeg to only use 3% of the CPU, which causes it to take
maybe 30 times longer than it should to create the DVD files before
burning the DVD.
Secondly and very important (since you are using cutlists in your burn) is
to make sure that each recording starts with a cut.
Not starting each recording with a cut appears to be a cause of the DVD
creation stopping with an error before even burning.
