Stefano Sabatini e35c0ee05c lavf/segment: fix computation of M3U8 segment target duration 
Use ceil on the max duration, rather than approximating it to the nearest
integer.
 2012-08-18 22:46:12 +02:00
Stefano Sabatini 69fc2489c4 doc/muxers: simplify segment examples 
The simplifications are due to the recent option changes.
 2012-08-18 12:32:54 +02:00
Stefano Sabatini 2d31ae2921 lavf/segment: change default value for segment_list_size option, from 5 to 0 
This is technically a major compatibility break, but seems the most
natural default and what users would expect without reading the docs.
 2012-08-18 12:32:23 +02:00
Stefano Sabatini 1c522e3868 lavf/segment: guess list type from list filename suffix 2012-08-18 12:31:49 +02:00
Stefano Sabatini dc7e4d685f lavfi/mp: remove framestep wrapped filter 
An equivalent framestep filter has been natively integrated.
 2012-08-18 12:14:46 +02:00
Stefano Sabatini 48d116400c lavfi: add framestep filter 
This filter is inspired upon libmpcodecs/vf_framestep.c, by Daniele
Forghieri.

Only-keyframe output is not supported, since that feature can be achieved
through the more versatile select filter.
 2012-08-18 12:13:34 +02:00
Stefano Sabatini 7cd5fa35fe lavfi/testsrc: set output framerate 2012-08-18 12:02:43 +02:00

Address trac ticket #1642.
 2012-08-18 11:21:47 +02:00
Stefano Sabatini 4a12d1e8e7 lavf/segment: compute max list segment duration 
This is useful for the M3U8 format incoming patch.
 2012-08-18 11:21:47 +02:00
Stefano Sabatini 769500c2a3 lavf/segment: create segment_list_open and close functions 
Allow factorization for the incoming patches, and avoid code/logic
duplication.
 2012-08-18 11:21:47 +02:00
Stefano Sabatini d3a2a614bf lavf/segment: fix bogus segment index rewrapping logic 
Decouple segment index wrapping and segment count logic. The counter
should not be reset since it detects the segment increasing timeframe.
 2012-08-18 11:21:47 +02:00
Stefano Sabatini b89e00bd1c lavf/segment: move file description to @file doxy 2012-08-18 11:21:47 +02:00
Stefano Sabatini 725213545d lavf/avio: flush internal buffer when calling avio_close() 
This seems the expected behavior.
 2012-08-18 11:21:44 +02:00
Stefano Sabatini 63f57f8530 lavf/avio.h: doxygen avio_flush() 2012-08-18 11:21:42 +02:00
Stefano Sabatini 5296d7b971 ffmpeg,ffplay: show filter options 
Address trac ticket #1599.
 2012-08-18 10:19:10 +02:00
Stefano Sabatini 42d621d131 lavfi: add priv class to filter definitions and flags to filter internal options 
This allows the iteration callbacks to discover the internal class and
options, and show them when required.
 2012-08-18 10:19:05 +02:00
Stefano Sabatini 831a999dda lavfi/movie: split class definitions for movie and amovie 
This is required for iterating through the filter class (without
incurring into a loop).
 2012-08-18 10:04:25 +02:00
Stefano Sabatini a77436abad lavfi/lut: duplicate class definitions for each lut variant filter 
This is due to the design of components iteration through AVClass
child_class_next() callback, which requires that two components cannot
share the same class.
 2012-08-18 10:04:25 +02:00
Stefano Sabatini 8e2cf68d09 doc/Makefile: add doc target, as an alias for "documentation" 
Consistent with --enable-doc, and easier to type.
 2012-08-18 10:04:25 +02:00
Stefano Sabatini 208d6e6615 lavfi/hue: add verbose debug message showing initial parameters 2012-08-16 15:02:09 +02:00
Stefano Sabatini 5b0151a474 lavfi/hue: reindent after previous commits 2012-08-16 15:02:09 +02:00
Stefano Sabatini 419e1b7463 lavfi/hue: apply misc fixes to default values setting 
In particular: signal error in case of bogus h:s values.
 2012-08-16 15:02:09 +02:00
Stefano Sabatini 6efce3a894 lavfi/mp: remove hue wrapped filter 
hue was integrated as a native libavfilter filter.
 2012-08-16 14:13:54 +02:00
Stefano Sabatini c3da2c19e4 build: extend documentation building mechanism 
Allow to select specific documentation components, and reliably check for
component dependencies.

In particular, check for perl presence on the system.
 2012-08-13 12:22:02 +02:00
Stefano Sabatini 5c0d8bc4ce lavfi: add avfilter_get_class() and iteration callbacks 
Allow iteration over filter options.
 2012-08-13 00:04:06 +02:00
Stefano Sabatini a25346e65c lavu/opt.h: add AV_OPT_FLAG_FILTERING_PARAM macro 2012-08-12 23:52:55 +02:00
Stefano Sabatini 3239382aef doc/texi2pod: add "use warnings" directive 
The script was previously run with perl -w through the shebang
command. Now that the script is executed through direct perl invocation
the -w in the shebang command is ignored. This patch re-enables "use
warnings" whatever way the script is invoked.

Idea-By: jamal <jamrial@gmail.com>
 2012-08-12 23:52:55 +02:00
Stefano Sabatini e874b29296 doc/Makefile: invoke perl to interpret texi2pod.pl 
Do not rely on shebang directive in the script, whose exact behavior is
system dependent.
 2012-08-10 23:14:57 +02:00
Stefano Sabatini ad5043e285 cmdutils: show options in show_help_children only if the context has options 
Avoid to print a pointless name of the context followed by an empty list.
 2012-08-10 23:14:44 +02:00
Stefano Sabatini a6d6b8a200 lavu/opt: fix crash in av_opt_next() in case the class has no options 2012-08-10 23:14:37 +02:00
Stefano Sabatini f6580b50ed lavfi: add asetpts audio filter 
Based on an idea by Andrey Utkin <andrey.krieger.utkin@gmail.com>.
 2012-08-09 01:03:05 +02:00
Stefano Sabatini 4270d8c04d lavd/x11grab: deprecate "nomouse" specification in filename 
Favor draw_mouse option. Should simplify parsing, and make it more
robust.
 2012-08-08 23:43:37 +02:00
Stefano Sabatini be2b885738 doc/indevs: document missing options in x11grab section 
Add documentation for options draw_mouse, framerate, and video_size.

In particular, fix trac ticket #1314.
 2012-08-08 23:43:37 +02:00
Stefano Sabatini c93b796c3e lavd/x11grab: apply misc consistency fixes to options definition 
In particular, do not upcase first word, do not use final dot, use a verb
to specify what the option does, sort entries by name, apply random
vertical align.
 2012-08-08 23:43:37 +02:00
Stefano Sabatini f09a06908e doc/indevs: use separate @example blocks for separate examples 
Improve rendering.
 2012-08-08 23:43:37 +02:00
Stefano Sabatini 083754f2be doc/indevs: rework options description in the x11 grab section 
Create a dedicated options subchapter, rather than a subchapter for each
option.

This is more consistent with the rest of the docs. Also apply misc minor
fixes for improving rendering.
 2012-08-08 23:43:36 +02:00
Stefano Sabatini 7794ddeae3 doc/ffmpeg: do not show examples making use of the deprecated glob_sequence pattern type 
The syntax of the 'glob_sequence' pattern type is explained in the image2
manual section, so there is no need to replicate it here.

Also discourage the use of such deprecated pattern type by not showing
examples employing it.

Replace the syntax explanation with an use example of the 'glob' pattern
type.
 2012-08-08 23:43:36 +02:00
Stefano Sabatini 3a06ea8436 lavf/img2dec: add and document pattern_type option 
Allow to override the default 'glob_sequence' value, which is deprecated
in favor of the new 'glob' and 'sequence' options.

The new pattern types should be easier on the user since they are more
predictable than 'glob_sequence', and do not require awkward escaping.
 2012-08-08 23:43:36 +02:00
Stefano Sabatini 0325e01fe7 doc/demuxers: itemize image2 examples and put them in a dedicated subsection 2012-08-08 23:43:31 +02:00
Stefano Sabatini dbf25b70ea lavfi/testsrc: set default value for option "color" to NULL and rework color setting logic 
Fix bogus warnings of the kind:
option 'color' is ignored with source 'testsrc'

when the color value is not explicitely set and the filter is different
from "color".
 2012-08-08 16:49:53 +02:00
Stefano Sabatini 13bbc464ed examples/muxing: set codec in the codec context 
Make add_{audio,video}_stream return the found codec, and pass it to
avcodec_open2() through open_{audio,video} functions.

Fix failure:
No codec provided to avcodec_open2().
could not open codec

This is also consistent with the use of the avcodec_open2() API in the
codebase.
 2012-08-07 20:04:19 +02:00
Stefano Sabatini 8331d56e0d doc/filters: fix typo in "@end table." 
Remove erroneously added trailing dot.
 2012-08-05 17:50:59 +02:00
Stefano Sabatini 8d6f46ab2c doc/filters: add mandelbrot source documentation 
Address trac ticket #1492.
 2012-08-05 15:45:55 +02:00
Stefano Sabatini 9bece76009 lavf/img2dec: add start_number_range option 2012-08-05 15:45:48 +02:00

Stefano Sabatini 74c6db0505 doc/demuxers.texi: avoid comma splice in image2 documentation 
Add "and" proposition for connecting two sentences.
 2012-08-05 00:47:55 +02:00
Stefano Sabatini b0d23ae208 lavf/img2doc: document options 2012-08-05 00:47:48 +02:00
Stefano Sabatini b5c7318bd7 lavf/img2dec: improve error logging in case of find_image_range() failure 2012-08-05 00:38:17 +02:00

Stefano Sabatini 48c1d1d3fa lavf/img2dec: introduce and use FIRST_INDEX_SEARCH_RANGE macro in find_image_range 2012-08-05 00:38:16 +02:00
Stefano Sabatini 07ef7b1a30 lavf/img2dec: fix out-of-range check in find_image_range() 
Take the new parameter start_index into account.
 2012-08-05 00:38:05 +02:00
Stefano Sabatini 59e4e40673 lavf/img2dec: doxygen find_image_range() function 2012-08-05 00:38:05 +02:00
Stefano Sabatini e408e329d2 lavf/img2dec: rename find_image_range() "max_start" parameter to "start_index" 
The new name seems more consistent with the assumed logic.

"start_index" represents the minimum accepted value as first index, and
not the maximum value as implicitely assumed by the previous name.
 2012-08-05 00:37:39 +02:00
Stefano Sabatini a30e776ff1 lavf/img2dec: fix weird start_number count logic 
This seems consistent with the assumed meaning of the option.
 2012-08-05 00:26:48 +02:00
Stefano Sabatini 66747a6160 examples/muxing: simplify alloc_picture() 
Use avpicture_alloc() high level function.
 2012-08-05 00:26:39 +02:00
Stefano Sabatini 44bd69e9b9 lavc/utils: rename ff_init_buffer_info() pic parameter to frame 
The new name is more expressive, given that the frame is not necessarily
a picture but may be an audio frame.
 2012-08-03 16:28:18 +02:00
Stefano Sabatini b99381e8b5 lavc/utils: generalize ff_init_buffer_info() and use it when seems feasible 
Extend ff_init_buffer_info() to init audio frames as well as video
frames.

Avoid code duplication.
 2012-08-03 16:28:12 +02:00
Stefano Sabatini 39a8275fdf lavfi: move color filter to testsrc, factorize 2012-08-03 16:26:58 +02:00
Stefano Sabatini aa5b93fbd8 lavfi/rgbtestsrc: use ff_fill_rgba_map() rather than a local copy 
Also convert int rgba_map[4] to uint8_t rgba_map[4], as required by
ff_fill_rgba_map().

Simplify.
 2012-08-02 12:32:48 +02:00
Stefano Sabatini 3bcde3f06c lavfi/drawutils: make ff_draw_color() accept a const rgba map 2012-08-02 12:32:48 +02:00
Stefano Sabatini 65520f5933 lavfi/video: remove duplicated function ff_null_start_frame_keep_ref() 
Semantic for the function ff_null_start_frame() was changed in
07bad27810, and it has now the same behavior of
ff_null_start_frame_keep_ref(), thus it makes no sense to keep both of
them.
 2012-08-02 12:32:48 +02:00
Stefano Sabatini 4c8fc6a2a4 lavfi/testsrc: use AVFILTER_DEFINE_CLASS for defining the filter classes 
Factorize.
 2012-08-01 22:47:23 +02:00
Stefano Sabatini 33474eb1c6 lavfi/testsrc: extend logic in request_frame, support static image output 2012-08-01 22:47:04 +02:00
Stefano Sabatini 20e940e768 lavfi/testsrc: free the context in uninit 
Keeping stuff in the context can be useful for debugging purposes.
 2012-08-01 22:46:08 +02:00
Stefano Sabatini 7ddf082f04 lavfi/testsrc: drop pointless parentheses 2012-08-01 11:05:47 +02:00
Stefano Sabatini 2702e38477 lavfi: remove unused defaults.c file 2012-08-01 11:05:41 +02:00
Stefano Sabatini 52bd9cb4d2 lavfi/movie: force channel layout if not set by the decoder 
This ensures that the output buffers will have the channel layout set,
which is required by filters.

Also consistent with ffmpeg.c behavior.
 2012-07-31 13:25:14 +02:00
Stefano Sabatini c809b89a12 ffprobe: show audio frame channels and channel_layout 2012-07-31 13:21:29 +02:00
Stefano Sabatini 23fc4dd6e7 lavc: add channels field to AVFrame 
This is required otherwise it is not always possible to guess the number
of channels from the layout, for example if the channel layout is
unknown.
 2012-07-31 13:21:10 +02:00
Stefano Sabatini b4c3359828 lavfi/asettb: do not create a new reference in filter_samples() 
There is no need to duplicate the input reference, since a filter should
not pass along a reference which is later modified. If this happens the
filter passing the reference should be fixed.

Also improve consistency with start_frame() of settb, allowing a pending
factorization.
 2012-07-31 13:15:51 +02:00
Stefano Sabatini a7c3720e87 lavu/bprint: readd documentation for 0 and 1 av_bprint_init() special values 
The documentation was erroneously removed in 7cf9aadd.
 2012-07-31 13:15:43 +02:00
Stefano Sabatini 316f6df9cc lavfi/avcodec: rename picref->samplesref variable in avfilter_get_audio_buffer_ref_from_frame() 
The new name is more meaningful in that context.
 2012-07-30 00:33:13 +02:00
Stefano Sabatini 9cf9214d0a lavfi/color: free internal context options in uninit() 
Keeping the set options in the context when the component is still used
can be useful for debugging purposes.
 2012-07-30 00:33:13 +02:00
Stefano Sabatini a74dcb7dc0 lavfi/color: cache and reuse colored picture in context 
Avoid to fill the same picture again and again with the same content.

Optimize computation, and provides an example for the use of the
AV_PERM_REUSE permission flag.
 2012-07-30 00:33:13 +02:00
Stefano Sabatini 47b6b7a2b9 lavfi/color: reindent after the previous commit 2012-07-30 00:33:13 +02:00

Stefano Sabatini fd2b6c1e4b doc/filters: itemize movie examples 2012-07-28 10:50:19 +02:00
Stefano Sabatini 32390d6767 lavfi: move movie and amovie to a "multimedia sources" section 
Since the recent changes, movie and amovie are able to deal with more
than one type of stream, so they should be categorized as "multimedia
sources" rather than audio/video sources.
 2012-07-28 10:50:11 +02:00
Stefano Sabatini 7cf9aaddcd lavu/bprint: extend/clarify documentation for av_bprint_init() size_max value 
Also define AV_BPRINT_SIZE_* macros before av_bprint_init() declaration,
and mention them in the av_bprint_init() doxy.
 2012-07-28 10:49:08 +02:00
Stefano Sabatini 10b44f4932 ffprobe: use av_guess_sample_aspect_ratio() for guessing the aspect ratio 
This is consistent with what av_dump_format() does.

In particular, fix trac ticket #1568.
 2012-07-25 10:05:02 +02:00
Stefano Sabatini 9b42d6ed1f lavf/avformat.h: fix verb person for av_guess_sample_aspect_ratio() 
Prefer impersonal form over third person, consistent with the rest of
docs.
 2012-07-25 10:04:57 +02:00
Stefano Sabatini e564de26b3 lavfi/avfilter.h: add doxy for AVFilterLink.out_buf 2012-07-25 10:03:34 +02:00
Stefano Sabatini b73be80d48 lavfi/avfilter.h: add doxy for AVFilterLink.cur_buf 2012-07-25 10:01:29 +02:00
Stefano Sabatini 7afd42d9f2 lavfi/showwaves: do not set on outlink->out_buf the sent video frame 
The video frame reference is passed along the filterchain, and is not
possessed anymore by the filter. If out_buf is not set to NULL, it will
be freed by ff_end_frame() causing a crash.
 2012-07-23 15:10:19 +02:00
Stefano Sabatini 8c2ce16f93 doc/filter_design: fix a few typos 2012-07-22 12:16:18 +02:00
Stefano Sabatini c0b91348fe lavd/caca: create display *after* checking dither options 
Avoid fastidious creation and immediate destroy of the display in case
one of the dither options fails to be set.

Also add NULL checks in write_trailer(), which are now necessary since
the function can be called when not all the components have been
initialized.
 2012-07-22 10:32:21 +02:00
Stefano Sabatini 9ce0e19ab6 lavd/caca: provide more meaningful feedback if fails to set a dither option 2012-07-22 10:32:15 +02:00
Stefano Sabatini fa71471cef lavd/caca: rename "colors" option to "color" 
More consistent with libcaca function names. Should not harm since the
device was added less than one day ago.
 2012-07-22 10:31:33 +02:00
Stefano Sabatini d510527885 lavd/caca: sort arguments for -list_dither 2012-07-22 10:28:23 +02:00

Stefano Sabatini 3bd3e46c91 doc/avtools-common-opts: fix a few typos in the "Stream specifiers" section 2012-07-20 12:56:28 +02:00
Stefano Sabatini 7e17389c1e lavd/sdl: use verb in options help message 
An help message tells what an option does, not what its argument is.
 2012-07-19 23:56:59 +02:00
Stefano Sabatini a8d8e868c6 lavf/udp: warn in case the circular_buffer_size or overrun_nonfatal options are not supported 
They are only supported if pthread is available.
 2012-07-19 22:48:09 +02:00
Stefano Sabatini e1422940f2 doc/protocols: add a note regarding the circular RX UDP buffer 2012-07-19 22:31:41 +02:00
