frame.

Fix crash when a following filter (e.g. settb) will unref the reference
passed by start_frame(), and then the reference is accessed in
end_frame() through inlink->cur_buf.
 2012-04-27 21:38:13 +02:00

 2012-04-07 13:57:40 +02:00
Stefano Sabatini 60e4e430db doc/muxers: clarify documentation for the framecrc muxer 
Makes more explicit that framecrc works at the packet level, also prefers
the term "packet" over "frame" when it makes sense.
 2012-04-07 13:57:39 +02:00
Stefano Sabatini fd00662d5a doc/muxers: update documentation for the framecrc muxer

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 
Previously it was returning 0 in case the aspect was parsable but
invalid.

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

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 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.

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.
