Adds output of chroma sub-sampling information to
ffprobe -show_pixel_formats option.

Note: This patch just prints the "raw" log2_charoma_w/h values instead
of the previously suggested mapping into a chroma sub-sampling pattern
string like "4:2:2".

  h263dec: Force padding bug workaround for H.263.

This is not merged as it breaks a good part of the error concealment/resilience for H.263
Also, messenger.h263 plays fine in ffmpeg.
If anyone has any other h263 files that do not work, please open an issue on trak or
mail me!

The spec requires this.

Fixes uninitialized reads on some samples.

Remove now unnecessary initialization of the whole merge candidate list.

The caller expects the MV to always be initialized.

This avoids warnings about using the codec time base as time
base hint.
Signed-off-by: Martin Storsjö <martin@martin.st>

By using ff_avc_write_annexb_extradata instead of the h264_mp4toannexb
BSF, the code for doing the conversion itself is kept much shorter,
there's less state to restore at the end, we don't risk leaving the
AVCodecContext in an inconsistent state if returning early due to
errors, etc.

Also add a missing free if the base64 encoding fails.

The register function now specifies that the user callback should
leave things in the same state that it found them on failure but
that failure to destroy is ignored by the library.  The register
function is now explicit about its behavior on failure
(it unregisters the previous callback and destroys all mutex).
