c977039e58 lavc, lavfi: fix counting number of planes in AVBufferRef wrappers 
Number of planes is not always equal to the number of components even
for formats marked with PIX_FMT_PLANAR -- e.g. NV12 has three components
in two planes.

6552808014 lavc,lavfi: fix calculating the plane size in the AVBufferRef wrappers 
It is supposed to be height * linesize, not width * linesize.
Thanks to Hendrik Leppkes for pointing out the bug.

a2816230c5 avframe: call release_buffer only if it is set

70762508ec lavc: Prettify printing of codec tags containing non alphanumeric characters 
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.

This also avoids relying on locale-dependent character class functions.

9a7dc618c5 libavcodec: Don't crash in avcodec_encode_audio if time_base isn't set 
Earlier, calling avcodec_encode_audio worked fine even if time_base
wasn't set. Now it crashes due to trying to scale the output pts to
the codec context time base. This affects e.g. VLC.

If no time_base is set for audio codecs, set it to the sample
rate.

e2ff436ef6 lavc: Relax API strictness in avcodec_decode_audio3 with a custom get_buffer() 
Do not fail audio decoding with avcodec_decode_audio3 if user has set a
custom get_buffer. Strictly speaking, this was never allowed by the API,
but it seems that some software packages did so anyways. In order to
unbreak applications (cf. http://bugs.debian.org/655890), this change
clarifies the API and overrides the custom get_buffer() with the defaults.

This change is inspired by a similar
commit (c3846e3eba) in FFmpeg.

When the buf and last pointers are equal, the FFSWAP() results
in an invalid call to memcpy() with same source and destination

C99, gcc does not check for this before calling memcpy().

f32fd31858 g722: Change bits per sample to 4 
Earlier, bits per sample was defined as 8, since
bits_per_coded_sample was used to indicate whether to ignore
the lower bits of the codeword, having values 6, 7 or 8.

g722 encodes 2 samples into one byte codeword, therefore the
bits per sample is 4. By changing this, the generated timestamps
for streams encoded with g722 become correct.

This makes timestamp generation for g722 data correct (both when
encoding and when demuxing from raw g722 files).
