Stefano Sabatini e34ad128a3 examples/muxing: reduce duration, remove wrong and misleading comment 
Set duration to 10 seconds, after it was increased from 5 to 200 seconds
in 8d80f3cb87.

200 seconds will generate too much data which is annoying especially when
testing.

Fix PTS set on the frame when encoding, which must be specified in the
encoder timebase or this will confuse the encoder.

When muxing the packet, the PTS/DTS generated by the encoder is then
rescaled to the stream timebase.

Stefano Sabatini 0aa325457d doc/muxers/segment: clarify ambiguos reference 
Replace "The segmenter muxer" with "This muxer". The "segmenter muxer"
was never defined before, and thus it is a slightly ambiguous term.

Simplify/extend syntax.
 2013-12-26 11:35:27 +01:00
Stefano Sabatini 334e2e2363 lavu,lavc,lswr: do not hardcode AV_SAMPLE_FMT_NB value when setting sample format max value 
The constant may change in libavutil but the library may be compiled
against an older version, thus rejecting a value which is otherwise
supported by the new libavutil.

INT_MAX is used here to denote the max allowed value for a sample format.

The opt-test code is changed to provide a valid reference example.

Stefano Sabatini 3b8c7da7a3 lavu,lavfi,lavd: do not hardcode AV_PIX_FMT_NB value when setting pixel format max value 
The constant may change in libavutil but the library may be compiled
against an older version, thus rejecting a value which is otherwise
supported by the new libavutil.

INT_MAX is used here to denote the max allowed value for a pixel format.

Stefano Sabatini 55f046be11 lavu/opt: apply range checks also when setting format string value

Stefano Sabatini 5b073da7a1 doc: add script to compute texi files dependencies 
Replace the inline awk script with a Perl script which tracks the
dependencies recursively.

This allows to correctly track dependencies for files including files
with a second level include (for example: ffmpeg-devices.texi ->
devices.texi -> outdevs.texi).

This also adds a dependency on perl for computing the dependencies, which
should not be a problem since perl is already required all the way for
building documentation.

This is a variant of commit 628ceac652
which was reverted due to out-of-tree build failure.
