Hi all,
I'd like to ask for comments about the following behaviour:
Some DVB-S transpoders are using VBR for all TV stations, and seem to
change maxBps in almost every sequence header (see below).
With libmpeg2-0.5.1, this triggers SEQUENCE_MODIFIED state, which
invokes player routines for aspect ratio changes etc.
libmpeg2-0.4.1 was deliberately ignoring changes in maxBps and
gave SEQUENCE_REPEATED state in such case.
Should the players now check for this situation, or would it make sense
to put back the previous behaviour - i.e. giving SEQUENCE_REPEATED
from libmpeg2 even if maxBps was changed?
Thanks & kind regards,
M.
