Make the mp wrapper accept the syntax mp=filter=params as alternative
to mp=filter:params. The alternative syntax is sligthly more readable
and should simplify copy&paste of MPlayer filter strings to the mp
filter.

Change position of the fade filter description, put it between
drawtext and fifo descriptions.

avcodec_thread_init currently doesn't do anything at all with pthreads enabled.

Fixes issue2632 if interl=1 is used or the automatic interlace detection is enabled
and works. This has the advantage compared to the patch in issue2632 that it causes
no speed loss and it also works when scaling is used. The disadvantage is that
interlacing autodetection does not yet work very well it seems.
This is the same method mplayer uses

In draw_glyphs(), draw glyphs in dtext->expanded_text rather than in
dtext->text. Fix crash if a strftime() sequence is used.

This is more consistent with the terminology adopted by the aspect
filter names.

This reverts commit f968ef92.

As previously discussed, the CrystalHD hardware treats some PAFF
clips different from others; even when input fields are always in
separate packets, the hardware might return a single fieldpair for
one clip and individual fields for another.

Given the bogus flags set by the hardware, it is impossible to
distinguish these two cases without knowing about the current
picture and the next one. The hardware can usually provide the
picture number of the next picture and when that is available,
we can detect the two cases.

When it is not available, we have to guess - and find out later
if we were right or wrong.

With this change, clips will play correctly unless they are PAFF
where individual fields are returned *and* no next picture number
is available. Generally speaking, the incorrect cases arise in
the first couple of seconds of a clip as the delay calibration takes
place. Once that's set, things work fine.

As previously discussed, the CrystalHD hardware returns exceptionally
useless information about interlaced h.264 content - to the extent
that it's not possible to distinguish MBAFF and PAFF content until
it's too late.

This change introduces use of the h264_parser to help bridge the
gap; it can indicate if the input data is PAFF fields or not.

With this clarity, some of heuristics can be removed from the code,
making this less convoluted.

Finally, I found an MBAFF clip that acts like non h.264 content so
I had to make allowances for that.

Note that I still cannot distinguish between two forms of PAFF,
where the hardware either returns individual fields or a field-pair.
It's not clear that there's even a spec relevant difference between
the two forms, as opposed to hardware ideosyncracies.

strtol could return negative values, leading to various error messages,
mainly "non-monotonically increasing dts".

Currently, only S16 quad, 5.1 and 7.1 are implemented.
Implementing support for other formats/layouts and capture should be
straightforward.

7.1 support by Carl Eugen Hoyos.

Provide a non-NULL AVFormatParameters structure to
av_open_input_file() in open_input_file().

This is required because otherwise av_open_input_file() will allocate
and use a new format context, discarding the options set in the
provided format context.

The function was only used in opt_sample_fmt() for listing the sample
formats. Move list_fmts() functionality directly into
opt_sample_fmt().

Als fix the warning:
ffmpeg.c: In function ‘opt_audio_sample_fmt’:
ffmpeg.c:2877: warning: passing argument 1 of ‘list_fmts’ from incompatible pointer type
cmdutils.h:163: note: expected ‘void (*)(char *, int,  int)’ but argument is of type ‘char * (*)(char *, int,  enum AVSampleFormat)’
