Stefano Sabatini 7bac6e5cf8 ffprobe: fix uninitialized variable warning 
Fix warning:
ffprobe.c:1684:21: warning: ‘start’ may be used uninitialized in this function [-Wmaybe-uninitialized] end = start + interval->end;

The warning is a false positive, since the variable is accessed only if
has_start is set, and in that case start has been already set.

Stefano Sabatini 838bd73139 lavfi: create Libav-API compatibility layer for avfilter_graph_parse() at the next bump 
Add function avfilter_graph_parse_ptr() and favor it in place of
avfilter_graph_parse(), which will be restored with the old/Libav
signature at the next bump.

If HAVE_INCOMPATIBLE_LIBAV_API is enabled it will use the
Libav-compatible signature for avfilter_graph_parse().

At the next major bump the current implementation of
avfilter_graph_parse() should be dropped in favor of the Libav/old
implementation.

Should address trac ticket #2672.
 2013-07-03 13:21:42 +02:00
Stefano Sabatini 5efbeae38c configure: rename have_incompatible_fork_abi -> have_incompatible_libav_abi 
"Fork" is an ambiguous term, since there may be more than one fork, also
"fork" could be confused with the corresponding function. Also it seems
important to point the name of the referenced fork in the symbol.

Note: the old --enable-incompatible-fork-abi command is retained for
compatibility, although it should be considered deprecated.

Stefano Sabatini 759dfd5684 examples/muxing: make more compact audio/video_time computation 2013-07-03 11:31:34 +02:00
Stefano Sabatini 628ceac652 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.
