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 8d80f3cb.

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.

Rely on frame_count. Also more consistent with audio path.

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.

  - do not allocate resample dst buffer when resample is off
  - free sample buffers in addition to freeing data pointer arrays

We generate S16 samples and we should allocate the right buffer

The open_codec_context function, when it fails to find a codec, now
return AVERROR(EINVAL) to signal an error.

Before it would return the stream index, which was always >= 0, and
continue as if a codec was found. This change make it fail faster,
instead of repeated failed tries to decode frames with no codec.
