cleaning it up is already done in avcodec_get_frame_defaults()

Since an AVFrame now has malloced members (extended_data), it must have
a destructor.

Otherwise the frame is uninitialized, so avcodec_get_frame_defaults()
cannot determine whether to free extended_data.

AVFrame is used for both audio and video, so calling the argument 'pic'
is misleading.

Ensure that padded_frame is freed before returning when needed.

AVCodecContext.encode is currently used only for subtitles, encode2 is
used for audio and video.

Silences a warning about discarding const.

If the packet has a PTS and the corresponding time base is known,
set the pts field of the decoded subtitle structure before the
call to the decoder. The decoder is still allowed to change the
PTS if necessary.

This can be used to avoid a time consuming lookup of the
descriptor

The new name is more expressive, given that the frame is not necessarily
a picture but may be an audio frame.

Extend ff_init_buffer_info() to init audio frames as well as video
frames.

Avoid code duplication.

This is required otherwise it is not always possible to guess the number
of channels from the layout, for example if the channel layout is
unknown.

Also: factor the the computation of the timestamp difference.

It is likely to happen if pkt_timebase was not set.

Compared to the decoder side, this code is able to change both the
delay and the number of threads seamlessly during encoding. Also
any idle thread can pick up tasks, the strict round robin in order
limit is gone too.

Make av_get_codec_tag_string() show codec tag string characters in a more
intelligible ways. For example the ascii char "@" is used as a number, so
should be displayed like "[64]" rather than as a printable character.

Apart alphanumeric chars, only the characters ' ' and '.' are used
literally in codec tags, all the other characters represent numbers.
