e34ad128a3 examples/muxing: reduce duration, remove wrong and misleading comment
Set duration to 10 seconds, after it was increased from 5 to 200 seconds
in 8d80f3cb87.

200 seconds will generate too much data which is annoying especially when
testing.

23ffc4c70d doc/examples/muxing: Fixes frame initialization.
Fixes use of the example with encoders which use tha AVFrame w/h/pix_fmt fields
FFV1 is one of these codecs

We cannot easily workaround the not set fields in common code because the API
has AVFrame constant for the encoders.
Alternatives would be to fix the API or to duplicate the struct and fill in
missing fields. Or as is to require all user apps to set this correctly and
maybe simplify for that case

80bca6eabe examples/muxing: honour distinction between encoder PTS timebase and stream timebase
Fix PTS set on the frame when encoding, which must be specified in the
encoder timebase or this will confuse the encoder.

When muxing the packet, the PTS/DTS generated by the encoder is then
rescaled to the stream timebase.
