Stefano Sabatini 7f08bfae6e lavf/segment: add segment_list_type option, extend format for the segment list file 
Add list extended format which specifies in the list file the start and
ending time for each segment. This is required to make it available this
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 
Better rather than silently exit.
 2012-07-03 23:26:07 +02:00

Option help message tell what the option *does*, not what the set field
represents.
 2012-07-03 21:48:50 +02:00
Stefano Sabatini a5af29336a lavf/segment: slightly simplify fail logic in seg_write_packet() 2012-07-03 21:48:50 +02:00
Stefano Sabatini 4ad17bc76b lavf/segment: move list filename printing logic from segment_end() to segment_start() 
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() 
Check on an implicit assumption done on the number of coded bits for
paletted rawvideo with coded bits == 2.
 2012-07-03 01:25:02 +02:00
Stefano Sabatini 17a54f5de8 lavc/rawdec: prefer constant AVPALETTE_SIZE over 256*4 
Improve readability.
 2012-07-03 01:24:56 +02:00
Stefano Sabatini aa1cceb5eb lavf/segment: rename variable "size" to "list_size" 
The new name is more meaningful/less confusing.
 2012-07-01 18:35:15 +02:00
Stefano Sabatini 3bee286ad2 lavf/segment: pass the top level chained muxer format context to segment_end() 
Consistent with segment_start() and less confusing.
 2012-07-01 18:35:06 +02:00
Stefano Sabatini b12e61ac7f ffplay: factorize expression in audio_decode_frame() 
Possibly improve readability.
 2012-06-30 15:01:51 +02:00
Stefano Sabatini 94a00ec8af ffplay: group together and vertically align correlated parameters in log function 
Possibly improve readability.
 2012-06-29 23:15:45 +02:00
Stefano Sabatini 8179660222 ffplay: vertially align complex if condition in audio_decode_frame()

Consistent with the rest of the file, less confusing.
 2012-06-29 17:04:19 +02:00
Stefano Sabatini a9a7e215e5 lavf/segment: add stream_segment variant of the segment muxer 
This simplifies usage for segment streaming formats with no global
headers, tipically MPEG 2 transport stream "ts" files.

The seg class duplication is required in order to avoid an infinite loop
in libavformat/utils.c:format_child_next_class().
 2012-06-29 17:03:25 +02:00
Stefano Sabatini 3cd4f9fd76 lavf: allow multiple names in output devices selected by av_guess_format() 
Consistent with av_find_input_format().
 2012-06-29 16:54:18 +02:00
Stefano Sabatini 0692d4c890 lavf/segment: add some debugging logs 2012-06-29 14:50:27 +02:00
Stefano Sabatini 567eb9d344 lavf/segment: fix command with missing -list option 
Replace -list with the correct option -segment_list.
 2012-06-29 14:50:27 +02:00
Stefano Sabatini d9355a03f2 lavf/applehttp: add log message in case of applehttp_read_header() failure 
Improve error reporting.
 2012-06-29 14:50:27 +02:00
Stefano Sabatini 4fd07b9366 ffplay: avoid useless NULL checks in swr_free() 
swr_free() already checks for nullness, no need to add the check in
calling code.
 2012-06-29 13:24:57 +02:00
Stefano Sabatini 4674718203 ffplay: fix wrong reference to function in audio_decode_frame() comment 
The comment now references swr_convert(), rather than audio_convert(),
which was deprecated and/or dropped.
 2012-06-29 13:24:43 +02:00
Stefano Sabatini 7877b50d18 ffplay: simplify code by using avfilter_unref_bufferp() 2012-06-28 22:27:05 +02:00
Stefano Sabatini b0fdd3489a lavfi: deprecate av_buffersrc_buffer() function 
Favor av_buffersrc_add_ref() instead, which is more powerful.
 2012-06-28 22:27:05 +02:00
Stefano Sabatini e6674e46ec lavu/imgutils: create misc functions for dealing with buffers 
Move the lavc/imgconvert functions and rename them as follows:
avpicture_get_size -> av_image_get_buffer_size()
avpicture_fill     -> av_image_fill_arrays()
avpicture_layout   -> av_image_copy_to_buffer()

The new functions have an align parameter, which allows to define the
linesize alignment assumed in the buffer (which is set or read).

The names of the functions are consistent with the lavu/samples API
(av_samples_get_buffer_size(), av_samples_fill_arrays()).
 2012-06-26 13:12:12 +02:00
Stefano Sabatini 79a7451d06 ffplay: add configure_filtergraph() helper 
Will help factorization with the pending -af patch, and add some checks
missing in the original code.
 2012-06-26 11:42:51 +02:00
Stefano Sabatini 720ec62012 lavfi: drop deprecated and disabled packing API 
It was deprecated and removed after the recent 2->3 major bump.
 2012-06-26 11:40:21 +02:00
Stefano Sabatini 8dd0e87d7b lavfi: remove old video sink API 
It was deprecated since a long time and removed after the 2->3 major
bump.
 2012-06-26 11:40:08 +02:00
Stefano Sabatini f054dbee6c tools/graph2dot: make dot graph representation a bit more compact 2012-06-26 11:34:38 +02:00
Stefano Sabatini 9b41ec4b9e lavfi/drawtext: use av_opt_free() to free private context 
Simplify code.
 2012-06-25 22:49:16 +02:00
Stefano Sabatini 6be8cfa034 lavfi/abuffer: increase logging level of the log showing initial parameters 
Also show them in a more parsable/consistent fashion.
 2012-06-25 22:49:16 +02:00
Stefano Sabatini 8a3544149f lavfi/avfilter.h: reorganize headers disposition 
Group lavfi headers together, slightly improve readability.
 2012-06-25 22:49:09 +02:00
Stefano Sabatini fec512a52c ffplay: give more meaningful names to the buffersink instances 2012-06-25 13:42:53 +02:00
Stefano Sabatini 43583fb85c lavfi/avcodec: deprecate avfilter_fill_frame_from_*_buffer_ref API 
Deprecate functions:
avfilter_fill_frame_from_buffer_ref
avfilter_fill_frame_from_audio_buffer_ref
avfilter_fill_frame_from_video_buffer_ref

and schedule to drop them at the next API major bump.

The function avfilter_copy_buf_props() should be used instead.
 2012-06-25 13:42:47 +02:00
Stefano Sabatini 972cad77fa lavfi: remove unnecessary inclusion of libavcodec/avcodec.h in avfilter.h 
libavfilter API was designed in order to be clarly distinguished from the
libavcodec API, including avcodec.h in avfilter.h is not going to help to
stick to this principle.

The inclusion of libavutil/audioconvert.h in many files was required
because avcodec.h includes audioconvert.h.

libavfilter/avcodec.h is where the lavc/lavfi interface should be
entirely placed.
 2012-06-25 13:42:37 +02:00
Stefano Sabatini a31ab50712 lavfi: move some FF_API_ definitions from avfilter.h to version.h 
version.h seems the right place for FF_API_ definitions.
 2012-06-25 13:42:29 +02:00
Stefano Sabatini c0ca840837 lavfi/buffer: remove unused function av_vsrc_buffer_add_frame_alt() 2012-06-23 00:42:51 +02:00
Stefano Sabatini 39e019e8c1 ffplay: add cast to fix warning in configure_video_filters() 
Fix warning:
ffplay.c:1578:40: warning: passing argument 5 of ‘avfilter_graph_create_filter’ discards ‘const’ qualifier from pointer target type [enabled by default]
libavfilter/avfiltergraph.h:84:5: note: expected ‘void *’ but argument is of type ‘const enum PixelFormat *’
 2012-06-23 00:42:51 +02:00
Stefano Sabatini 1dce2368bb lavfi/buffer: apply misc consistency nits 2012-06-23 00:42:51 +02:00
Stefano Sabatini 201b409da0 lavc/pcm: clarify error message from pcm_decode_frame() 
Extend/clarify an error message in case of invalid packet size, and
return a proper error message instead of -1.
Improve debuggability.
 2012-06-23 00:42:51 +02:00
Stefano Sabatini c17808cebd lavfi: define macro AVFILTER_DEFINE_CLASS 
The macro can be used to define consistently the internal class of a
filter, save some typing and factorize.
 2012-06-22 23:11:43 +02:00
Stefano Sabatini 012aa12a6b lavfi/drawtext: remove unnecessary parentheses in init() 2012-06-22 23:11:43 +02:00
Stefano Sabatini 1bb30d0295 lavfi/deshake: fix crash in uninit() 
Add NULL check on avctx before calling avcodec_close() on it.

Fix trac ticket #1472.
 2012-06-21 17:01:44 +02:00
Stefano Sabatini cb08b6efc9 lavfi/scale: remove unused variable out_link 
Fix warning:
libavfilter/vf_scale.c: In function ‘start_frame’:
libavfilter/vf_scale.c:284:23: warning: unused variable ‘out_link’ [-Wunused-variable]
 2012-06-21 12:47:48 +02:00
Stefano Sabatini c0b3c0ffb7 lavfi/audio: remove unused variable in ff_filter_samples() 
Fix warning:
libavfilter/audio.c: In function ‘ff_filter_samples’:
libavfilter/audio.c:193:13: warning: unused variable ‘size’ [-Wunused-variable]
 2012-06-21 12:47:48 +02:00
Stefano Sabatini 065851ffac lswr/rematrix: specify explicitly the name of the unsupported channel layouts 
Help debugging.
 2012-06-21 12:47:47 +02:00
Stefano Sabatini 98701be356 lavfi/ass: update use of deprecated functions, fix warnings 2012-06-21 11:11:56 +02:00
Stefano Sabatini eda4500866 lavfi/blackdetect: add logic for handling stream termination 
Add request_frame() which checks the black duration when the end of the
stream is signalled. Allow to detect black video segments at the end of
the stream.

Note that the reported last black video segment duration is not very
accurate, since we still miss the duration information in the video
buffer.

Address trac ticket #1470.
 2012-06-21 11:11:50 +02:00
Stefano Sabatini 5bc87f1cd6 lavfi/blackdetect: fix pts time debug printing 2012-06-21 11:00:20 +02:00
Stefano Sabatini 3ea3e32e03 lavfi: add showwaves filter 2012-06-20 12:37:57 +02:00
Stefano Sabatini 93bbe53c44 lavfi/asplit: fix memleak 
The input samples buffer must be unreferenced after it is propagated to
the output links.
 2012-06-20 12:37:50 +02:00
Stefano Sabatini db142a8395 lavfi/avcodec: make avfilter_fill_frame_from*() functions use avfilter_copy_buf_props() 
The code in avfilter_copy_buf_props() is more generic, allow code
factorization.
 2012-06-19 16:44:36 +02:00
Stefano Sabatini 8f8d8b9538 lavfi/avcodec: always use av_frame* accessors in avfilter_copy_buf_props() 
Use av_frame_* accessors for the newly added fields in AVFrame (for which
we are supposed to use such accessors), and group the istructions
accordingly.
 2012-06-19 16:44:35 +02:00
Stefano Sabatini d5761fe47d lavfi/avcodec: copy pos field from AVFilterBuffer to AVFrame pkt_pos 2012-06-19 16:44:35 +02:00
Stefano Sabatini 208c5a08da lavc/qtrlenc: return proper error codes from qtrle_encode_init() 2012-06-19 16:44:35 +02:00
Stefano Sabatini 5793a6d9f9 lavc/libschroedinger: add missing failure checks in ff_create_schro_frame() 2012-06-19 16:44:34 +02:00
Stefano Sabatini c90e8054af lavc/avcodec.h: fix reference to nonexistent function in av_picture_copy() doxy 
Mention av_image_copy() instead.
 2012-06-19 01:36:39 +02:00
Stefano Sabatini 18b4404dc3 lavc/imgconvert: fix check on av_image_check_size() return code in avpicture_get_size() 
The documentation states that av_image_check_size() will return a
negative value in case of error, while the check is done on ret != 0.

Also return a proper error code rather than -1 in case the check fails.
 2012-06-19 01:36:30 +02:00
Stefano Sabatini 0b2ecf8224 lavc/imgconvert: remove pointless switch block from avpicture_fill() 2012-06-19 01:36:23 +02:00
Stefano Sabatini b583ccc3db lavc/rawdec: propagate duration from packet to frame 2012-06-19 01:36:17 +02:00
Stefano Sabatini 8f45c3141c ffplay: rename buffer source instance from "src" to "ffplay_buffer" 
The new name is more descriptive.

 2012-06-17 20:32:24 +02:00
Stefano Sabatini 251f398798 ffplay: use key=val syntax for the buffersrc args 
Fix warning:

Stefano Sabatini d70a1a507d MAINTAINERS: reorganize entries in the libavfilter section 2012-06-17 22:17:44 +02:00
Stefano Sabatini 2b1fc5621d lavfi: add asetnsamples audio filter 
This filter changes the number of samples on single output operation.

Based on a patch by Andrey Utkin <andrey.krieger.utkin@gmail.com>.
 2012-06-16 00:54:20 +02:00
Stefano Sabatini e20530add7 lavfi/split: give a more accurate description to split 
The filter now supports a configurable number of outputs.
 2012-06-16 00:46:58 +02:00
Stefano Sabatini a1411eec21 ffprobe: add writer_print_rational() 
Improve overall consistency, allow some factorization.
 2012-06-16 00:42:54 +02:00
Stefano Sabatini b6131ac5d3 doc/filters: prefer @itemize environment for frei0r examples 2012-06-16 00:31:03 +02:00
Stefano Sabatini eb732b2ade doc/filters: update Frei0r website link 
Frei0r recently changed website host.
 2012-06-16 00:30:54 +02:00
Stefano Sabatini b2bcbcd999 lavfi/super2xsai: simplify code updating the color matrix at each y iteration 
Remove duplicated out-of-loop init code, and do color matrix
initialization at the beginning of each y iteration.

Allow factorization and avoid an useless matrix update in the last
iteration.
 2012-06-16 00:30:48 +02:00
Stefano Sabatini 4ebb46eb14 lavfi/super2xsai: fix table used to update color matrix at the end of each y loop 
The previous table appears to be wrong (it was copied from the original
MPlayer super2xsai filter in order to keep binary compatibility).

The new table is consistent with the init code and apparently fixes a
combing artifact on the left edge of the generated image.
 2012-06-16 00:30:42 +02:00
Stefano Sabatini ef255642d5 fate/lavfi: add lavfi-pixfmts_super2xsai test 2012-06-16 00:30:33 +02:00
Stefano Sabatini 635a25954e lavfi/video: set output frame w/h properties in default_start_frame() 
Use the same values of the video output link.

Avoid the need to override the default_start_frame() with an ad-hoc
start_frame() callback.

In particular, fix the super2xsai filter which was setting the
input w/h values in the output.
 2012-06-16 00:30:27 +02:00
Stefano Sabatini f0394f28c3 lavfi/avcodec: add consistency checks in avfilter_copy_buf_props() 
The function will abort through an assert if the source is not defined,
or if the internal state of the source is inconsistent (e.g. type = AUDIO
&& !src->audio).
 2012-06-16 00:30:13 +02:00
Stefano Sabatini 6808759a58 lavc/rawdec: fix various bogus error codes and add some logs 
Help debugging.
 2012-06-16 00:30:05 +02:00
Stefano Sabatini 3cc1a89881 lavc/utils: in avcodec_decode_video2() return proper error code instead of -1 
Return AVERROR(EINVAL) in case of invalid coded size.
 2012-06-16 00:29:59 +02:00
Stefano Sabatini 465a72b4b4 lavfi: move definition of avfilter_copy_buf_props() from buffer.c to avcodec.c 
avcodec.c is where it is defined the lavc/lavfi interface code, so seems
a more adequate location (and doesn't force the inclusion of
libavcodec/avcodec.h where it is not required).
 2012-06-13 10:51:33 +02:00
Stefano Sabatini 134815a030 lavfi: change name of tracing functions and of the macro which enables them 
The enabling symbol is renamed FF_AVFILTER_TRACE. Avoid conflicts with
the DEBUG macro, which may be defined for different purposes.
 2012-06-13 10:51:15 +02:00
Stefano Sabatini 359abb18cf lavu/error: add av_make_error_string() and av_err2str() convenience utilities 
These functions are modeled after the corresponding utilities in
libavutil/timestamp.h.
 2012-06-11 23:57:01 +02:00
Stefano Sabatini 5683de00e9 lavu/error: fix sign error in av_sterror() error code 
The value returned by strerror_r may be positive depending on the system,
so it is necessary to use AVERROR() in order to get a negative
number. This way the successive negative check will not fail, and the
function will print a meaningful error message on the buffer.
 2012-06-11 23:56:31 +02:00
Stefano Sabatini 4299fd23d3 lavu/error: use a table to store error codes and strings, add test 
The table is mostly useful to enumerate the available AVERROR* in the
test output.
 2012-06-11 23:35:32 +02:00
Stefano Sabatini 3ecaba677e tests/parseutils: change test to make it platform independent 
Make the test independent from the actual error string used to describe a
certain error code.
 2012-06-11 23:35:31 +02:00
Stefano Sabatini ee1748ab53 lavfi: fix signature for default_filter_name()

Stefano Sabatini 8d1de449f0 ffprobe: show packet duration in frame 2012-06-06 23:26:04 +02:00
Stefano Sabatini 9083d09ebb ffprobe: honour special value for duration 
A duration value is undefined when is 0, take into consideration this
fact when printing optional fields.
 2012-06-06 23:26:04 +02:00
Stefano Sabatini ad347bf459 lavfi: remove avfilter_default_item_name() from public API 
The function was introduced in 4d6a8a2bdb and is not used anymore
outside avfilter.c.

This avoids to pollute the public API with an apparently unnecessary
function. The function was introduced a few days ago, so removing it from
