Stefano Sabatini f0158e6f0c lavf/flvenc: fail in case the muxed packet is too big 
Avoid the creation of files which cannot be successfully decoded by
ffmpeg, for example generated with:
ffmpeg -f lavfi -i sine -af "aselect='not(between(t,100,500))',aresample=min_comp=0.001:min_hard_comp=0.100000" -acodec pcm_s16le -t 1000 -y out_audio.flv

Stefano Sabatini 7e4a4bda0e doc/filters/apad: extend documentation 2014-08-21 16:59:18 +02:00
Stefano Sabatini aade9884e9 lavfi/apad: fix logic when whole_len or pad_len options are specified 
In particular, allow pad_len and whole_len to have value set to 0, which
means that no padding will be added. Previously a value set to 0 meant
that that the filter had to pad forever.

The new semantics is clearer, also simplifies scripting since the option
value might be automatically computed, so that no checks need to be done
in case it is 0.

The old semantics was never documented and the logic was broken (the
filter was always adding samples indefinitely), so this should not break
backward compatibility.

Fix trac issue #3850.
 2014-08-13 18:14:24 +02:00
Stefano Sabatini ac1e3882cc doc/ffserver: merge paragraph starting with "What happens next?" with previous one 
The name of the paragraph sounded a bit silly, and its text is small so
it's better to merge it with the previous paragraph.
 2014-08-03 11:27:27 +02:00
Stefano Sabatini 44071b0d25 lavf/segment: sanitize segment end time in case last packet do not have a defined duration 
In particular, avoids to set segments with duration set to 0
(e.g. segment with a single reference frame for which duration is
undefined).
 2014-07-22 13:53:31 +02:00
Stefano Sabatini 713157484a lavf/segment: do not allow to create segments with no key-frames 
Fix trac ticket #3749.
 2014-07-22 13:43:06 +02:00
Stefano Sabatini 526bd7bdfa lavf/segment: set segment end time when the first packet arrives 
Avoid negative durations in case there is a single packet in the current
segment, since in that case the end time is still set to the previous
segment end time.
 2014-07-17 16:51:51 +02:00

Stefano Sabatini 5acad50056 lavf/segment: only use reference frames for computing the segment end time 
This avoids a systematic overestimate of the segments duration when there
are several streams.

Fix trac ticket #3724.

This is useful for debugging purposes.
 2014-07-05 11:48:24 +02:00
Stefano Sabatini 85eabd748b lavfi/drawtext: do not allocate FT_Glyph, but keep it in the Glyph structure 
Slightly simplify.
 2014-07-05 11:48:06 +02:00
Stefano Sabatini 462c9ee3ac lavfi/overlay: show incoming frames on debug messages 
This is especially useful to debug queue overflow issues.

Ideally we should be able to set the debug message at the
dualinput/framesync level, but they do not have the information related
to the filter context and the inlink, so cannot access much useful
information.
