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 6300062774 lavfi/transpose: add support to named options and shortands 
Allow extensibility.
 2012-10-02 09:20:10 +02:00
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.
 2012-09-29 10:25:11 +02:00
Stefano Sabatini 01e4537f66 ffprobe: rework/fix flat writer 
Do not build from scratch the section header for each section, but build
using the previous level buffer, thus improving efficiency and fix some
few corner cases which are exposed by the pending disposition patch.
 2012-09-29 10:25:04 +02:00
Stefano Sabatini 06fd4c2dfa ffprobe: generalize nesting model for the compact writer 
Regular section fields nested in a regular section are now prefixed by
the nested section name.

This is required by the pending change related to disposition.
 2012-09-29 10:24:53 +02:00
Stefano Sabatini 44c1cc3f8e ffprobe: generalize nesting model for the default writer 
Regular section fields nested in a regular section are now prefixed by
the nested section name.

This is required by the pending change related to disposition.
 2012-09-29 10:24:45 +02:00
Stefano Sabatini b6ea9c8765 ffprobe: drop SECTION_ENTRY macro 
The use of the macro makes to add new optional fields somewhat harder.
 2012-09-29 10:24:36 +02:00
Stefano Sabatini 23564a4a4a ffprobe: add support to library ident printing 2012-09-29 10:24:28 +02:00
Stefano Sabatini ed2b69a4c3 ffprobe: remove unused "args" argument in writer init callback 
The parameter is no longer used, since the arguments are parsed at the
framework level.
 2012-09-28 16:37:27 +02:00
Stefano Sabatini 163f7afbe6 ffprobe: fix indentation of the first line of packets_and_frames sections in the json output 2012-09-27 01:10:46 +02:00
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.
 2012-09-26 11:07:09 +02:00
Stefano Sabatini 2089f93300 ffprobe: drop pointless opaque parameter in writer init callback 
The parameter was never used.
 2012-09-25 11:02:52 +02:00
Stefano Sabatini 58e9025993 ffprobe: reindent after previous commit 2012-09-25 09:22:00 +02:00
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.
 2012-09-25 09:20:57 +02:00
Stefano Sabatini bbe9fe469a lavf/utils: remove loop on AVERROR(EAGAIN) in av_read_frame() 
The loop was introduced in 64d340c62a, and
was likely breaking non blocking reads as it busy loops.
 2012-09-24 21:16:48 +02:00
Stefano Sabatini f3bd6fa7a8 lavc/mmvideo: forward reget_buffer return value in mm_decode_frame() 2012-09-24 14:57:49 +02:00
Stefano Sabatini efa3d5af1e lavc/roqvideodec: fix error message

log header.
 2012-09-24 12:02:38 +02:00
Stefano Sabatini b1fee1be61 lavc/roqvideodec: propagate reget_buffer() error code 2012-09-24 12:02:31 +02:00
Stefano Sabatini d2c70ec07f lavc/roqvideodec: remove useless headers 2012-09-24 12:02:23 +02:00
Stefano Sabatini d40b197ca8 tests/fate-ffprobe: fix typo in metadata comment 2012-09-24 10:32:52 +02:00
Stefano Sabatini 10c00f7a04 tests/fate-ffprobe: use an ffmetadata file for the injected metadata 
Workaround commandline msys issues, also allow more flexibility.
Should fix ffprobe tests on mingw+MSVC.
 2012-09-24 10:04:44 +02:00
Stefano Sabatini 64d340c62a lavf/utils: add error check in av_read_frame() 
In particular, fix crash when the input file contains no packets (e.g. an
ffmeta input).
 2012-09-24 00:41:13 +02:00
Stefano Sabatini 740c995288 lavfi: add asendcmd and sendcmd filters 2012-09-23 00:50:06 +02:00
Stefano Sabatini 7fe1ecefe1 lavfi/hue: simplify/fix setting logic in set_options() 
Parse expression only when a new value is explicitly specified.

In particular, avoid double free in case an old expression value is
cached, it is set in the context, it is freed as the old value, and
finally the pointer stored in the context is freed again when the filter
is released.
 2012-09-23 00:46:33 +02:00
Stefano Sabatini ab4ee9fd5e tests: update fate-ffprobe test to make use of -bitexact flag 
Should fix tests with --enable-small.
 2012-09-22 09:34:56 +02:00
Stefano Sabatini 42047c3e86 ffprobe: reindent after the previous commit 2012-09-22 09:34:56 +02:00
Stefano Sabatini 4cd1addcc4 ffprobe: add -bitexact boolean option 
The option is mostly useful to make ffprobe output independent from the
build, and in particular to fix FATE --enable-small failures.
 2012-09-22 09:34:56 +02:00
Stefano Sabatini 9543cd593e ffprobe: print format long_name only if non-NULL 
Fix possible crash when long_name is not defined (for example if
--enable-small).
 2012-09-21 13:59:18 +02:00
Stefano Sabatini 3aa1b53256 lavfi/hue: set to NULL freed pointers 
Possibly safer.
 2012-09-21 12:44:44 +02:00
Stefano Sabatini 31aa5b1a78 lavfi/hue: fix crash when resetting the saturation expression 
Previously when saturation was reinited, the old value was freed when
setting options, and freed again in PARSE_EXPRESSION().
 2012-09-21 12:43:52 +02:00
Stefano Sabatini 0f40105aaa ffprobe: print codec_long_name only when available 
Avoid possible segmentation fault if codec_long_name is defined as
NULL (for example if --enable-small).
 2012-09-21 09:27:06 +02:00
Stefano Sabatini 5bd6a4800d tests: add fate-ffprobe test 2012-09-20 12:13:18 +02:00
Stefano Sabatini 53d71335cb lavd/lavfi: push frames until the last sink is EOF 
Previously the device was returning EOF when the first sink was ending,
with the current change the device will continue to return frames until
all the sinks are EOF, which seems the most expected behavior.
 2012-09-20 12:13:17 +02:00
Stefano Sabatini 98f753ec51 lavfi/testsrc: increase precision of the duration parameter 
Compute duration in microseconds, rather than in timebase units. Decrease
approximation errors.
 2012-09-20 12:13:17 +02:00
Stefano Sabatini f398617b19 ffprobe: fix CSV writer output 
Fix regression introduced in 749ddc14fc.
 2012-09-19 11:50:05 +02:00
Stefano Sabatini 1ad63ff14a fate: add av_small_strptime() test to fate-parseutils 2012-09-17 12:46:55 +02:00
Stefano Sabatini 85c93d90df lavu/parseutils: fix av_small_strptime() whitespace directive parsing 
According to POSIX, strptime() should consume whitespaces in the date
string everytime a whitespace conversion specification is found in the
date format specification. Make av_small_strptime() conform with this
behavior.

In particular, should fix trac ticket #1739.
 2012-09-17 12:45:56 +02:00
Stefano SabatiniandAnton Khirnov 5d1203f063 avio: flush the internal buffer in avio_close() 
This is consistent with stdio, and thus what people would naturally
expect.
 2012-09-15 18:24:49 +02:00
Stefano Sabatini 8bdba0b3e9 tools: move raw-test program to tools, with the name fourcc2pixfmt 2012-09-14 23:04:38 +02:00
Stefano Sabatini 363307813e tools/graphdot: unbreak syntax 
Fix regression introduced in f054dbee6c.
+10.23l.
 2012-09-14 11:29:25 +02:00
Stefano Sabatini dead4580e2 lavfi/avcodec: apply cosmetics style fixes 2012-09-14 11:06:40 +02:00
Stefano Sabatini 8d0e871f25 ffprobe: kill initializers with nested union field definition 
The c99-to-c89 converter (for MSVC support) doesn't currently handle
designated initializers or compound literals with nested unions or
structs.

This is apparently the only place where this construct is used in the
FFmpeg codebase.
 2012-09-14 10:47:08 +02:00
Stefano Sabatini 5e99a23b2d ffprobe: avoid potentially lossy long long int -> double cast in value_string() 
Previously the cast long long int -> double was always performed (and
then the double was converted back to long long int) even when it was
avoidable.
 2012-09-14 10:42:54 +02:00
Stefano Sabatini 51fa653829 examples/decoding_encoding: clarify operations in the usage message 2012-09-13 22:19:45 +02:00
Stefano Sabatini bcf93f78a5 examples/decoding_encoding: replace "picture" with "frame" in encode_example()

Stefano Sabatini 1d0048cfe3 examples/muxing: rename img_convert_ctx to sws_ctx 
The new name is more consistent with the codebase, and more
self-consistent with the libswscale API.
 2012-09-11 21:43:18 +02:00
Stefano Sabatini 976bb42aca examples/muxing: merge some declarations and definitions 2012-09-11 21:41:56 +02:00
Stefano Sabatini bdd9bfbbab examples/muxing: prefer AVPicture to AVFrame, when feasible 
Favor the use of plain AVPicture over AVFrame, especially when the use of
AVFrame is not required like in the case of tmp_picture.

Also adopt more straightforward names, to avoid frame/picture confusion.
 2012-09-11 21:41:56 +02:00
Stefano Sabatini e592fd0ed1 lavf/flvenc: convert commented debug log to an av_dlog call 
Also add some additional info (DTS and DTS time).
 2012-09-11 18:58:19 +02:00
Stefano Sabatini 3015194448 lavfi/amerge: clarify the error message in case of input overlap 2012-09-11 18:58:19 +02:00

output.
 2012-09-11 01:14:57 +02:00
Stefano Sabatini f740c1a9c2 ffprobe: add and use DEFINE_WRITER_CLASS macro 
Factorize writer class definition.
 2012-09-11 01:02:20 +02:00
Stefano Sabatini 206c34e17d lavfi/setpts: set SAMPLE_RATE to NAN when input is no audio 
Should be more robust/consistent.
 2012-09-10 18:52:28 +02:00
Stefano Sabatini 722762f7e1 lavfi/setpts: add FRAME_RATE constant 
Useful for dealing with constant frame-rate video.
 2012-09-10 18:52:28 +02:00
Stefano Sabatini e4fe4d01fc ffprobe: simplify default printer 
Remove pointless default_print_footer() and
default_print_chapter_header() callbacks, also avoid to print an
empty line when noprint_wrappers is selected.
 2012-09-10 10:22:36 +02:00
Stefano Sabatini eab438eabb lavu/samplefmt: fix/clarify documentation for av_samples_fill_arrays() 
In particular, avoid improper use of the term "channels" in place of
"planes", and fix erroneous documentation for the linesize parameter.
 2012-09-09 11:41:17 +02:00
Stefano Sabatini 3634441452 lavu/samplefmt: add note regarding buf validity in av_samples_fill_arrays() doxy 2012-09-09 11:21:45 +02:00
Stefano Sabatini a4cb0af945 lavfi: drop deprecated and pointless avfilter_default_end_frame() function 
Fix warning when compiling boxblur.

While this is technically a major API break, practically there will be no
one using that function since the filtering API is mostly private, so
that function alone is not usable.
 2012-09-09 10:57:28 +02:00
Stefano Sabatini 09cc23e0f7 lavd/sdl: decrease debug info notice log level from AV_LOG_INFO to VERBOSE 
Decrease log spam.
 2012-09-07 14:31:38 +02:00
Stefano Sabatini a7c7b34d29 lavd/sdl: remove trailing dot in messages 
This is consistent with the apparently prevailing convention.
 2012-09-07 14:31:37 +02:00
