Whenever av_gettime() is used to measure relative period of time,
av_gettime_relative() is prefered as it guarantee monotonic time
on supported platforms.

This mirrors the demuxer behaviour and avoids accessing
AVCodecContext.codec, which should not be done in muxers.

Also, return a proper error code.

By default, macro EPEL_FILTER loads the coefficients inconditionally
into m14/m15. This forces an unneeded higher register count.

Reduce that count by making them parameters of EPEL_FILTER.

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.

It is not supposed to be set from outside of libavcodec.
Set average framerate instead.

Do not call an AVCodecContext 'stream', that is highly confusing.
Also, add a local variable for the current AVStream in the loop over all
streams.

Do not leave a non-zero extradata_size set on failure

coded_frame is not meant to be changed from outside of lavc, and is not
used for decoding.
Set AVCodecContext.field_order instead.
