It is implied by av_register_all(). Simplify.

The avcodec_get_frame_defaults() function is deprecated and its use
doesn't seem required.

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.

More consistent and more future-proof.

Also log output packet information.

Show how to perform streamcopy from one container to another.

Improve consistency with the rest of the documentation.

In particular:
* set default value for accuracy to 15 (max)
* add zoomspeed for dynamic zoom (optzoom=2)
* make camera path optimization algorithm configurable
* update optzoom documenation in code to use new localmotions calculation function commandline arguments
* add debug option in vidstabtransform

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

In particular, fix trac ticket #3231.

Simplify logic, avoid multiple unnecessary alloc/free operations.

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.

Avoid the need of tweaking, also show how to get list of supported sample
formats.
