Stefano Sabatini 006e20bd36 lavfi/overlay: add enable expression
This expression is useful to enable/disable overlaying on the fly.

Note that this can't be easily done relying on the filtergraph structure,
since this implies caching issues or a null frame overlaying in the best
case, which is better avoided for performance and convenience reasons.

Stefano Sabatini cc3edd99a6 lavfi/overlay: add dynamic expression evaluation support
Add support for dynamic x, y expressions evaluation.

Also add support for an evaluation mode which allows to disable per-frame
evaluation, so that there is no speedloss in case the expression does not
depend on frame variables.

Stefano Sabatini 495ed19b5b cmdutils: remove error message from opt_default() in case of missing option
A similar error message is generated by the calling function, avoid
duplication and spurious error message occurring with negated boolean
options introduced in 8bb5680, which can be reproduced for example with
the command:
ffmpeg -f lavfi -i testsrc=d=0.1 -nostdin -f null -

Stefano Sabatini 33b0549867 lavc/utils: add VP6F hack for setting correct video size in stream
For some obscure reasons avcodec_set_dimensions() resets the width/height
so that the resulting value set in the stream is equal to the
corresponding coded_width/height, which is not the same as the correct
width/height in case of the H.264 and VP6F codecs.

This adds a codec-specific hack for VP6F which disables the call to
avcodec_set_dimensions() in avcodec_open2(), like it is done with H264. A
proper fix needs to be found yet.

Fix trac ticket #1386.

Based on a patch by Michael Niedermayer.

were not even documented and we just released a major version that should
not be a serious issue.

is a partial fix for Trac ticket #2332, a complete overhaul of boolean
options documentation is probably overkill.

Stefano Sabatini 70762508ec lavc: Prettify printing of codec tags containing non alphanumeric characters
Make av_get_codec_tag_string() show codec tag string characters in a more
intelligible ways. For example the ascii char "@" is used as a number, so
should be displayed like "[64]" rather than as a printable character.

Apart alphanumeric chars, only the characters ' ' and '.' are used
literally in codec tags, all the other characters represent numbers.

This also avoids relying on locale-dependent character class functions.
