The reasoning behind this addition is that various third party
applications are interested in getting some motion information out of a
video "for free" when it is available.

It was considered to export other information as well (such as the intra
information about the block, or the quantization) but the structure
might have ended up into a half full-generic, half full of codec
specific cruft. If more information is necessary, it should either be
added in the "flags" field of the AVMotionVector structure, or in
another side-data.

This commit also includes an example exporting them in a CSV stream.

Some files seem to have an off-by-one error. In most cases, it appears to
be on the image width. Therefore, if the decoded image doesn't fit in the
screen:
- If it is wider than the screen (and the lzw decoding buffer), reject it;
- Otherwise, decode the indicated amount, but only write a truncated amount
  to the screen.

As of September 14 2012, v4l_enumstd() will return ENODATA
when a device's std field is set to 0. That is, the device
does not have a standard format. In order to properly
handle this case, v4l2_set_parameters should catch the
ENODATA code and break instead of failing.

Below is the v4l2-core commit describing this change.

>>    [media] v4l2-core: tvnorms may be 0 for a given input, handle that case
>>
>>    Currently the core code looks at tvnorms to see whether ENUMSTD
>>    or G_PARM should be enabled. This is not a good check for drivers
>>    that support the STD API on one input and the DV Timings API on another.
>>    In that case tvnorms may be 0.
>>    Instead check whether s_std is present (for ENUMSTD) or whether g_std or
>>    current_norm is present for g_parm.
>>    Also, in the enumstd core function return ENODATA if tvnorms is 0,
>>    because in that case the current input does not support the STD API
>>    and ENUMSTD should return ENODATA for that.

The raw coded bits are extracted prior to decorrelation, as is correctly
performed by the decoder, and not after.

With the previous change, unknown attributes are all ignored,
as specified by the RFC.

The current code would use any unknown attribute-value pair
as the cookie value.
RFC 6265 states that the first key-value pair is the actual
cookie, and the attribute-value pairs only start after.

With the current code:
Set-Cookie: test=good_value; path=/; dummy=42
gives this:
Cookie: dummy=42
instead of this with the new code:
Cookie: test=good_value

Update mxf_set_audio_pts to use the container-provided information.

The UL is marked as "to be changed in the future", but the current
samples in the wild do use it.

And use it to print non-parsed ULs.
