Use mythtranscode --buildindex instead. This will only work for recordings,
if its a video (under mythvideo), you need the patch to ticket # 3533.
Actually, mythcommflag will sometimes create the MARK_GOP_START and
sometimes as MARK_GOP_BYFRAME . Just depends what the initial key frame
distance is in the file.
Also if it chooses MARK_GOP_BYFRAME it will almost always create a wrong
position map since it divides the frame # by the key frame distance. It
shouldn't, it should just store the frame # in the position map. When the
file is played back with a position map of MARK_GOP_BYFRAME, the key frame
distance is set to 1, which is not the same as when mythcommflag generated
the position map in the first place.
