01649c79c8 lavfi/buffersrc: set channel layout if it is known. 
If buffersrc was configured for frames with an unknown layout,
the incoming frames will have channel_layout = 0.
If the format negotiation has selected a known (and compatible)
channel layout for the link, the frame is assumed to have
that layout, the field must be set before injecting the frame
in the filters.

271f411267 lavf/matroskaenc: avoid assert failure in case of cuepoints with duplicated PTS 
Avoid to write more than one cuepoint per track and PTS in
mkv_write_cues(). This avoids a later assertion failure on "(bytes >=
needed_bytes)" in put_ebml_num() called from end_ebml_master(), in case
there are several cuepoints per track with the same PTS.

This may happen with files containing packets with duplicated PTS in the
same track.

The new code is also faster and more robust.

As for the performance:

old decoder + conversion to rgb:         fps = 2618
old decoder, without converting to rgb:  fps = 4012

new decoder, producing rgb:              fps = 4502
