Comment (by yrrqxk):
Unfortunately it's not just this one file. I'm trying to grab a large
amount of youtube videos with youtube-dl and I can't afford to manually
intervene with each one (several exhibited the same issue before I gave
up).
I am assuming the DASH segments overlap by a bit at the beginning and end
of each segment, with the keyframe being the first frame in the next
segment. Is there maybe an -fflags setting to just take the data from only
one of the files when there's an overlap? Why isn't this an issue when the
file is transcoded?
