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 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

ticket #1243.
 2012-07-15 15:57:11 +02:00
Stefano Sabatini fda968aa8f lavfi: decrease logging level of message showing initial parameters 
Reduce log clutter, consistent with 1a49a169eb.
 2012-07-15 15:07:03 +02:00
Stefano Sabatini 160df9797e lavc/tiffenc: apply misc doxy fixes 2012-07-14 13:02:51 +02:00

Stefano Sabatini fb57180698 lavc/avcodec.h: keep avframe_* field setter and getter close 
Slightly more readable, now that the list is getting longer.
 2012-07-14 13:02:25 +02:00
Stefano Sabatini bd58f00ec1 doc/filters: prefer "special" over "magic" for special input/output labels 2012-07-14 11:40:08 +02:00
Stefano Sabatini b65ccce866 doc/filters: update documentation 
In particular, assume existence of audio and sink filters.
 2012-07-14 11:39:31 +02:00
Stefano Sabatini 5a6c7a218c doc: merge libavfilter.texi into filters.texi 
There is no much point into splitting documentation for filters. Also
having a separate document for a library is inconsistent.
 2012-07-14 11:38:53 +02:00
Stefano Sabatini a5382b50f2 lavfi/buffersink: restore possibility to pass opaque data 
Use the init_opaque callback for the purpose.

Fix regression introduced in a5e8c41c28. In particular, fix lavfi
device in case a conversion to the supported (packed) formats is needed.
 2012-07-10 01:29:47 +02:00
Stefano Sabatini 21d5609826 lavfi: add init_opaque callback 
This will be used by filters which require an opaque field to be passed
in input. Should be required only for filters which imply a programmatic
use.

This is possibly a temporary solution, to be removed when we'll have a
clearer and better agreememnt of how/if to pass binary data for
initializing a filter.

See thread:

information to external tools, avoiding the need to perform file analysis
in the output segments.

reword the examples section.
 2012-07-04 01:17:58 +02:00
Stefano Sabatini af392efe51 lavf/segment: rename SegmentContext.pb to list_pb 
The new name is more auto-explicative, as the pb is used for the segment
list file.
 2012-07-04 00:02:56 +02:00
Stefano Sabatini d8013f38ab lavf/segment: add error log in case of invalid filename template

Allow to deal with the list file printing only in a single point, thus
simplifying logic, and allow a bit of factorization (no special case
needed when printing the first file name of the list).
 2012-07-03 21:48:50 +02:00
Stefano Sabatini bb6effe059 lavfi: remove vsrc_buffer.h API 
The vsrc_buffer.h is not installed since commit 0b3b958135, so there is
no point into keeping it around.

The buffersrc.h API, which is more powerful, should be used instead.
 2012-07-03 01:32:16 +02:00
Stefano Sabatini ab7dbdc92c lavc/rawdec: add assertion check in raw_decode()
