Vittorio Giovara 40cf1bbacc Deprecate avctx.coded_frame
The rationale is that coded_frame was only used to communicate key_frame,
pict_type and quality to the caller, as well as a few other random fields,
in a non predictable, let alone consistent way.

There was agreement that there was no use case for coded_frame, as it is
a full-sized AVFrame container used for just 2-3 int-sized properties,
which shouldn't even belong into the AVCodecContext in the first place.

The appropriate AVPacket flag can be used instead of key_frame, while
quality is exported with the new AVPacketSideData quality factor.
There is no replacement for the other fields as they were unreliable,
mishandled or just not used at all.

Andre Wolokita 44e95a017c lavd/v4l2: do not fail when VIDIOC_ENUMSTD returns ENODATA
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.

>>    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

>>    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.

Olivier Langlois 0a15067047 lavd: Use av_gettime_relative()
Whenever av_gettime() is used to measure relative period of time,
av_gettime_relative() is prefered as it guarantee monotonic time
on supported platforms.

Since v4l2 is compiled only on Linux where av_gettime_relative()
is monotonic, a small wrapper function av_gettime_monotonic() is used
(should be inlined the compiler) to put emphasis on that fact.
