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

 2012-10-31 15:46:46 +01:00
Stefano Sabatini be0b37c649 lavf/avienc: fix/extend error message, in case of too large number of skipped frames 2012-10-31 14:46:40 +01:00
Stefano Sabatini f35d5f966f lavf/avienc: enable debug log 2012-10-31 14:46:24 +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

 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 ce875a613a doc/texi2pod.pl: drop unnecessary rule, which was converting "\," to ","

escaped filtergraph snippets.

Fix trac ticket #1610.

 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

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 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.

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.

Stefano Sabatini 301f6da039 ffprobe: extend disposition printing support 
This generalizes the previous work on disposition printing.

Disposition flags are shown in a dedicated section, which should improve
output intellegibility, extensibility and filtering operations.

This breaks output syntax with the recently introduced disposition
printing.
 2012-09-30 12:22:19 +02:00
Stefano Sabatini 50efde6bcb ffprobe: generalize nesting model for the XML writer 
Do not make use of ad-hoc "tags" code, introduce a new section flag
SECTION_FLAG_HAS_VARIABLE_FIELDS to deal with the tags in a
content-agnostic way.

This is required by the pending disposition change.
 2012-09-30 12:07:47 +02:00
Stefano Sabatini 74bd0cf49c ffprobe: rework/fix ini writer 
Do not build from scratch the section header for each section, but build
it using the previous level buffer, thus improving efficiency.

Also fix some few corner cases related to numbering which are exposed by
the pending disposition patch.

Stefano Sabatini 06fd4c2dfa ffprobe: generalize nesting model for the compact writer 
Regular section fields nested in a regular section are now prefixed by

Stefano Sabatini 44c1cc3f8e ffprobe: generalize nesting model for the default writer

Stefano Sabatini b6ea9c8765 ffprobe: drop SECTION_ENTRY macro

Stefano Sabatini 4552e9b56c ffprobe: generalize writer subsection nesting model 
Discard unflexible structure based on the root/chapter/section layout in
favor of a generalized concept of section.

This should allow to represent sections at a generic level of nesting,
and allow subsection fields selection.

Also, simplify the code.

Stefano Sabatini 4b370d6126 ffprobe: rework checking logic in writer_print_time() and writer_print_rational() 
Make writer_print_time() and writer_print_rational() always call
writer_print_int() or writer_print_string(). This way the checks for
determining if the value should be printed or not are consistently
performed in the low level functions.

writer_print_rational() is moved downward in order to avoid a forward
reference.

Simplify/amend the overall logic.

Stefano Sabatini bbe9fe469a lavf/utils: remove loop on AVERROR(EAGAIN) in av_read_frame()
