 2013-04-25 11:19:53 +02:00
Stefano Sabatini f40cf96ec0 doc: remove all-components.texi, include its content verbatim 
Force re-generation of the manuals when an included file is modified.
The current dependency generation system is enable to track nested
inclusions.

The drawback is that the files will be generated even when there is no
strict need (for example if filters.texi is modified, ffmpeg.1 is
rebuilt), thus it trades a false negative with a false positive.

Stefano Sabatini e4fd58f472 lavfi/hue: apply major simplifications, and switch to AVOption-based system 
This also drops support for "flat syntax" and "reinit" command.

"reinit" command is not very robust and complicates the logic more than
necessary, since requires to reset all the options in the command.

*This is a syntax break*.
 2013-04-11 21:37:19 +02:00
Stefano Sabatini cff8f91ddf lavfi/decimate: switch to an AVOption-based system 2013-04-11 00:20:01 +02:00

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.
 2013-04-10 13:11:27 +02:00
Stefano Sabatini cc3edd99a6 lavfi/overlay: add dynamic expression evaluation support 
Add support for dynamic x, y expressions evaluation.

evaluation, so that there is no speedloss in case the expression does not
depend on frame variables.
 2013-04-10 13:11:27 +02:00
Stefano Sabatini 8afcaaeb75 lavu/eval: rename "new_eval_expr()" to "make_eval_expr()" 
The new name is more semantically and stilistically consistent.

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 -
