subtitles.
 2012-03-21 15:14:28 +01:00
Stefano Sabatini c9399538b7 lavfi/ass: use a default DAR value of 1.0

inconsistent with most implementations.

Fix trac ticket #1098.
 2012-03-21 15:14:28 +01:00
Stefano Sabatini e71e65ff1d lavfi/aspect: check for a negative code from av_parse_ratio() 
Check on < 0 rather than on != 0, this is more correct as a positive
error code from av_parse_ratio() value doesn't mean an error.
 2012-03-21 15:14:28 +01:00
Stefano Sabatini e19ccc89ef lavfi/aspect: fail with AVERROR(EINVAL) in case of invalid specified aspect

symbol reference in avcodec_open2().
 2012-02-20 17:46:18 +01:00

Stefano Sabatini 2cbe9121ac doc/filters.texi: use multiple @example blocks for distinct examples in setdar docs 2012-02-06 11:30:54 +01:00
Stefano Sabatini 23534d0c4c doc/filters.texi: prefer @example over the unsupported @math for showing equation 2012-02-06 11:30:54 +01:00
Stefano Sabatini 3fa9ace3d8 doc/filters.texi: merge setdar and setsar documentation 
Most of the documentation is common to both filters, and I'm going to add
more shared docs. Factorize.
 2012-02-06 11:30:54 +01:00
Stefano Sabatini 70ffda3217 lavu: introduce av_parse_ratio() and use it in ffmpeg and lavfi/aspect 
Factorize code and provide ratio parsing consistency.
 2012-02-06 11:30:54 +01:00
Stefano Sabatini 1ca0812d90 ffprobe: fix typo in ESCAPE_CHECK_SIZE 2012-02-06 11:30:45 +01:00
Stefano Sabatini a9117c755e lavfi: fix mp and mandelbrot descriptions to make them complete sentences 
This is consistent with the other filter descriptions.
 2012-01-21 14:40:46 +01:00
Stefano Sabatini 23934e5f41 ffprobe: increase precision for the shown float values 2012-01-20 13:27:57 +01:00
Stefano Sabatini 4601ad769d ffprobe: fix value_string() prefix printing for values with negative logarithm 
The index for the binary_unit_prefixes array is expected to be positive,
so avoid to use negative indexes for accessing it.

Second attempt at fixing ticket #921.
 2012-01-18 00:44:28 +01:00
Stefano Sabatini 2c8d37c2fb ffprobe: use safer type for index variable in value_string() 
There is no guarantee that the casted double which is assigned to the
variable will be contained in an int (also if it is almost sure for most
non-alien architectures).
 2012-01-18 00:43:55 +01:00
Stefano Sabatini 54661219c1 ffprobe: fix printing of unit values which cannot be contained in an int 
Use long long int to contain such values instead of an int, which is
required to contain at least 64 bits, so it is guaranteed to contain also
int64_t values, which are used by some fields.

In particular, should fix trac ticket #921.
 2012-01-18 00:01:07 +01:00
Stefano Sabatini 6c06868e61 doc/ffmpeg.texi: specify symbolic names for the vsync parameter 2012-01-17 23:50:47 +01:00
Stefano Sabatini 24860a913c tools: add ffeval tool 
The tool is useful for testing the internal arithmetic evaluation engine
(indeed I plan to use it in FATE), and provides a handy calculator when
you can't rely on bc ;-).
 2012-01-17 12:10:07 +01:00
Stefano Sabatini e4e291061c doc/eval.texi: add precisation about the assumption for "trueness" in conditional expressions 2012-01-17 12:03:30 +01:00
Stefano Sabatini 999495734b lavu/eval: add if() and ifnot() eval functions 
They allow to implement the if/then/else logic, which cannot be
implemented otherwise.

For example the expression:
A*B + not(A)*C

always evaluates to NaN if B is NaN, even in the case where A is 0.
 2012-01-17 12:03:30 +01:00
Stefano Sabatini a798c20a76 lavfi/testsrc: add "decimals" option to the testsrc filter 2012-01-17 12:03:30 +01:00

information in the message itself.
 2012-01-17 12:03:30 +01:00
Stefano Sabatini bb4c0abc7c ffplay: mark i variable in toggle_full_screen() as unused 
Fix gcc warning:
ffplay.c: In function ‘toggle_full_screen’:
ffplay.c:2792:9: warning: unused variable ‘i’ [-Wunused-variable]

Consistent with ffmpeg and ffplay.

Stefano Sabatini 4fd1e2e432 ffprobe: fix leak in show_packets() 
Call av_free_packets() at each demuxing loop iteration, not only when
decoding.

X-ColaCount: +10l
 2012-01-12 10:39:24 +01:00
Stefano Sabatini 7328c2fc21 ffprobe: replace av_destruct_packet() with av_free_packet() 
av_destruct_packet() always frees the packet data even when the demuxer
is going to re-use it, thus causing crashes when decoding audio
frames (as implemented in a pending patch).

av_free_packet() is used instead, as it allows each demuxer to set the
right packet data releasing mechanism through the pkt->destruct callback.
 2012-01-12 10:39:24 +01:00
Stefano Sabatini a8b0ece6e5 lavfi/testsrc: add "d" alias for the duration option 2012-01-12 10:39:24 +01:00
Stefano Sabatini 0cc8864687 ffprobe: use av_toupper() in upcase_string() 2012-01-10 22:49:15 +01:00

Stefano Sabatini 5226be0dd5 ffprobe: add -show_program_version and -show_library_versions options 2012-01-10 18:24:07 +01:00
Stefano Sabatini d3e435164b ffprobe: make upcase_string() ignore non-ASCII characters 
This is required as some section names may contain non-ASCII characters
(e.g. '_').
 2012-01-10 18:19:31 +01:00
Stefano Sabatini 3b1355bb93 ffprobe: change formatting logic in the JSON writer 
Print a "\n" at the end of each section, also print the section name in
the section print function, print the chapter name only in case the
chapter contains multiple entries.

Increase textual output readability - different sections can be
distinguished more easily.
 2012-01-09 13:41:35 +01:00
Stefano Sabatini 48f37b1d21 ffprobe: implement generic reindent logic in the JSON writer 
Clarify/generalize indent logic.
 2012-01-09 13:36:10 +01:00
Stefano Sabatini 5ccdb907c1 ffprobe: use more meaningful names for writer chapter/section header/footer function 
The passed argument is supposed to be the chapter/section name, rather
than the header/footer. Less confusing.
 2012-01-08 11:20:31 +01:00
Stefano Sabatini ec624d7c5c ffprobe: use "%*" printf syntax in XML_INDENT() in place of a loop 
Possibly faster/cleaner.

 2012-01-08 11:19:27 +01:00
Stefano Sabatini 9997d41672 ffprobe: add support to video frame information printing 
Add -show_frames option to ffprobe.

Partially based on the work of Thomas Kuehnel <kuehnelth@googlemail.com>
for SOCIS 2011.

The wicked idea of creating a special "packets_and_frames" container for
structured formats (JSON and XML) comes from Clément.

Stefano Sabatini 9ecccd6e5a ffprobe: move header and trailer print from probe_file() to main() 
Simplify printing from the main() context, in case probe_file() is not
called, as required by the pending -show_version option.
 2012-01-07 11:08:00 +01:00
Stefano Sabatini fa7d1c39fd ffprobe: move writer context registration and initialization in main() 
Simplify pending changes, as the writer context will be used in the

 2012-01-01 16:16:50 +01:00
Stefano Sabatini 549b53e8cb lavfi: remove redundant definition of avfilter_copy_frame_props() in avfilter.h 
Rationale: avfilter_copy_frame_props() was already defined in
libavfilter/avcodec.h, and keeping the lavc/lavfi API glue localized in a
specific file should ease maintainance and help the ones which use
libavfilter without depending on libavcodec.

Stefano Sabatini e9af732a1a lavfi: fix avfilter_default_get_audio_buffer() after changes in av_samples_alloc() 
av_samples_alloc() behavior changed in bbb46f3ec, resulting in random
data filling the data[] and linesize[] arrays of the returned
AVFilterBufferRef, which was resulting in wrong behavior in case of code
checking on data[i] nullity.

In particular fixes crash in avfilter_filter_samples():
        for (i = 0; samplesref->data[i]; i++)
            memcpy(link->cur_buf->data[i], samplesref->data[i], samplesref->linesize[0]);

and correctly fills the linesize[] array for planar data.
