 2012-11-03 23:35:50 +01:00
Stefano Sabatini 6450c05ba5 lswr/swresample: adopt globally consistent rules for options help message 
The help text tells what the option does, not what the accepted parameter
is. Thus convert strings of the kind:

Bikeshed Color
to
set bikeshed color
 2012-11-03 20:38:02 +01:00
Stefano Sabatini 0372ecfa48 lavc/options_table: force non-negative bitrate range

Stefano Sabatini a62242678f ffmpeg: complain loudly and exit in case removed -sameq option is specified 
This is better than silently ignoring the option, which results in
unexpected quality results.
 2012-11-03 12:05:43 +01:00
Stefano Sabatini c9eaa98a3e doc/ffmpeg: remove -debug option description 
The option belongs to libavcodec, so it results duplicated in the file.
 2012-11-03 11:01:48 +01:00
Stefano Sabatini 7669144ada doc/platform: Comply With All Capitalized Words Convention 2012-11-01 19:37:41 +01:00

particular, should address trac ticket #1813.
 2012-11-01 11:47:35 +01:00
Stefano Sabatini 1b21642149 lavfi/scale: avoid to print a NULL value in log message

 2012-10-31 15:46:46 +01:00

Stefano Sabatini 29a9e4d5c9 lavfi/mp: drop the mp=rectangle filter 
All the rectangle features have been ported to the native drawbox filter,
which has an equivalent syntax.
 2012-10-31 14:46:18 +01:00
Stefano Sabatini 9d478f38cd lavfi/drawbox: add "width" and "height" aliases for "w" and "h" options 2012-10-31 14:43:47 +01:00
Stefano Sabatini 93399e9381 lavfi/drawbox: add thickness option 2012-10-31 14:43:47 +01:00

Stefano Sabatini 1b3fdd9731 lavfi/drawbox: implement color=invert mode 
Based on a libmpcodecs/vf_rectangle.c feature.
 2012-10-31 12:14:21 +01:00
Stefano Sabatini 652fab5996 lavfi/mp: drop wrapped field filter 
The filter has been ported to a native libavfilter filter.
 2012-10-31 12:14:09 +01:00
Stefano Sabatini 3c4aa50620 lavfi: add field filter 
The filter is a port of libmpcodecs/vf_field.c, since there is no common
code I relicensed it as LGPL, while keeping the original author
copyright.
 2012-10-31 12:07:11 +01:00
Stefano Sabatini 1730dcf093 doc/filters: fix typo in drawbox section 2012-10-30 23:48:24 +01:00

Stefano Sabatini b420b87848 lavfi/tinterlace: remove poll_frame() callback 
That interface is deprecated, and apparently useless.
 2012-10-30 23:32:20 +01:00
Stefano Sabatini 7691860c73 lavfi/frei0r: update link to spec 
Fri0r project moved from piksel.org to frei0r.dyne.org.
 2012-10-29 18:48:00 +01:00
Stefano Sabatini 19add3224f lavfi/scale: implement clever/insane parsing heuristic, and add a size option 
If the first argument can be read as a video size, set that output size
in the scale. This allows to specify in a filtergraph scale=qcif or
scale=320x240.

This is not completely safe, for example in case of a typo in the video
size string the first argument will be read as the input width
expression, giving rise to a confusing comment.
 2012-10-29 17:44:53 +01:00
Stefano Sabatini d4604d10fe lavu/parseutils: add trailing characters check in av_parse_video_size() 
Return an error in case the video size specifications contains spurious
trailing chars, like in "320x240foobar".
 2012-10-29 17:39:26 +01:00
Stefano Sabatini adf0cd1456 doc/filters: itemize scale examples, and create a dedicated subsection for them 2012-10-29 17:39:26 +01:00
Stefano Sabatini c2428ada71 lavfi/scale: return error code in case of failed reconfiguration in start_frame() 
Avoid an assert, since now the function supports error code return.
 2012-10-29 17:39:26 +01:00
Stefano Sabatini 83938c3d4c lavfi/scale: accept named options, make parsing more robust 
Also update documentation accordingly.
 2012-10-29 17:39:26 +01:00
Stefano Sabatini 7d1e003abd doc/syntax: add a "Quoting and escaping" section 2012-10-29 11:56:15 +01:00
Stefano Sabatini 74e81b4de1 tests: do not set bogus scale sws_flags option in the scalenorm test 
sws_flags is not a valid scale option, and thus is ignored.
 2012-10-28 17:20:50 +01:00
Stefano Sabatini 15f52e50fe tools: add ffescape utility 2012-10-25 23:56:16 +02:00

which use it. Simplify.

Stefano Sabatini a161def1e4 Doxyfile: update examples path and patterns 2012-10-24 23:40:15 +02:00
Stefano Sabatini ce875a613a doc/texi2pod.pl: drop unnecessary rule, which was converting "\," to "," 
I cannot find a reason for such a rule, which was resulting in badly
escaped filtergraph snippets.

Fix trac ticket #1610.
 2012-10-24 23:33:47 +02:00
Stefano Sabatini 55c77a0ca3 doc/filters: escape special Texinfo character @ in overlay example 2012-10-24 17:22:00 +02:00

 2012-10-24 00:29:37 +02:00
Stefano Sabatini 4a227a706d lavc/utils: fix a few grammar/style nits in log messages

the beginning of a sentence, in the messages issued in case of
experimental codec usage.
 2012-10-24 00:29:37 +02:00
Stefano Sabatini 5ffadec30a lavc/utils: propagate or return meaningful error codes in avcodec_open2() 2012-10-24 00:29:37 +02:00
Stefano Sabatini 8b03cd3cd7 lavd/lavfi: add graph_file option 
Allow to specify a filename where to put the filtergraph description.

This is useful to override limitations or glitches of particular shell
environments, and allows a level of indirection for specifying
filtergraphs.
 2012-10-23 22:08:55 +02:00
Stefano Sabatini bd6240e7e9 lavfi/sendcmd: move buf init() variable to internal scope where it is used 2012-10-23 22:08:55 +02:00
Stefano Sabatini c7065f1f89 lavfi/sendcmd: release file in case of failed allocation 
Avoid hanging file.

Add support for named options, and deprecate old "num:den" ambiguous
syntax.
 2012-10-22 10:46:34 +02:00
Stefano Sabatini b6e36a4244 lavu/parseutils: remove unused gcd variable in av_parse_ratio() 
Fix warning.
 2012-10-22 10:41:51 +02:00
Stefano Sabatini 8f37a1e8dc lavfi/avfiltergraph: avoid to print "(null)" in the scale args 
Fix parsing.
 2012-10-21 21:44:53 +02:00
Stefano Sabatini 2969abd908 lavfi/graphparser: fix parsing error in case of NULL sws_opts addition 
If sws_opts was NULL it was resulting in the args being set to
"W:H:(null)", which with the new parsing code was generating a syntax
failure.
 2012-10-21 21:44:45 +02:00
Stefano Sabatini 8c2dbc3805 lavc/utils: provide more feedback in case of experimental codec 2012-10-21 21:11:02 +02:00
Stefano Sabatini d3b8d56e06 examples/decoding_encoding: prefer 'frame' over 'picture' for an AVFrame 
Decrease confusion.
 2012-10-20 19:42:55 +02:00
Stefano Sabatini cdea54b4c8 lavu/parseutils: rework rational reduction logic in av_parse_ratio() 
Avoid to divide num and den by gcd in case of a parsed expression, since
that is already done in av_d2q(), and force reduction in case of "a:b"
form, allowing to honour the max parameter.

The latter change is consistent with the a/b case, and with the
documentation.
 2012-10-20 12:19:53 +02:00

Based on libcompface code by James Ashton <James.Ashton@anu.edu.au>, and
relicensed to LGPL with the author's consent.

Stefano Sabatini c4aaff8c02 Revert "configure: link flite against libasound" 
This reverts commit 396648cc6a.

The commit made impossible to build against libflite if libasound is not
available (e.g. on Windows). Thus remove the -lasound flag. In case of
libflite static linking the workaround is to enable
--extra-ldflags=-lasound (or disable the ALSA output device in libflite).
 2012-10-11 11:19:18 +02:00
Stefano Sabatini 396648cc6a configure: link flite against libasound 
libflite depends on libasound. Fix a linking failure when linking against
a static version of libflite.
