Some muxer use the FLV field PreviousTagSize to be the sum of tag
length. Without this change, the flv demuxer think the file is broken
and the re-sync will fail.

"If biCompression equals BI_RGB and the bitmap uses 8 bpp or less, the
bitmap has a color table immediatelly following the BITMAPINFOHEADER
structure. The color table consists of an array of RGBQUAD values. The
size of the array is given by the biClrUsed member. If biClrUsed is
zero, the array contains the maximum number of colors for the given
bitdepth; that is, 2^biBitCount colors."

Nothing about "monochrome" here. Unfortunately, pal8 to monow conversion
seems a bit flaky, but that's another story.

Simplify parsing and consistency.

The COPYING.LIB file in the zvbi source tree as well as libzvbi.h references
the GNU Library General Public License version 2 since version 0.2.28.

It uses the libzvbi slicer, therefore teletext capture requires libzvbi.

This option can force the segmenter to only start a new segment if a packet
reaches the muxer within the specified duration after the segmenting clock
time, which makes it more resilient to backward local time jumps, such as leap
seconds or transition to standard time from daylight savings time.

The private options chromaoffset, sc_threshold, and noise_reduction
were set to 0 rather than -1, and were always initializing values
in libx264 rather than letting the library use its default.
Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

After the merge the default threshold was unconditionally overwritten

A similar fix was written by Vittorio Giovara, but i didnt see that before
i wrote this and it also doesnt apply cleanly

This uses a new MMAL feature, which limits the number of extra frames
that can be buffered within the decoder. VIDEO_MAX_NUM_CALLBACKS can
be defined as positive or negative number. Positive numbers are
absolute, and can lead to deadlocks if the user underestimates the
number of required buffers. Negative numbers specify the number of extra
buffers, e.g. -1 means no extra buffer, (-1-N) means N extra buffers.

Set a gratuitous default of -11 (N=10). This is much lower than the
firmware default, which appears to be 96.

This is backwards compatible, but needs a symbol only present in newer
firmware headers. (It's an enum item, so it requires a check in
configure.)

I guess this means part 2 in both cases. Not sure which profiles exactly
are actually supported properly.

Slight simplification. The result is the same. Also, change the
wording of the message as requested in patch review.

The mmal decoders do not depend on the software decoders.
