Comment (by mrpingouin):
After some tests and more investigation, it turned out that neither
input.http() nor strip_blank() are guilty. The problem came from the use
of crossing (smart_crossfade()) on the input HTTP stream. This is not
possible: the HTTP input has some realtime constraints that can't meet the
requirements of crossing. Technically, this results in repeated frames,
hence repeated metadata. This raises again the need for a static detection
of such bad situations. After changing this, the problem doesn't seem to
occur anymore. This is to be confirmed later, to close the ticket.
To be fair, I also leave it open to test a bit more that "dirty" case.
Indeed, crossing an external stream should not always result in repeated
frames (this only occurs if we add sharing to the mix, probably via
smooth_add in Azrael's case). I may want to understand the details of
this... but may also consider that such scripts should not be written at
all anyway.
