Merge remote-tracking branch 'newdev/master'
* newdev/master: mov: set audio service type for AC-3 from bitstream mode in the 'dac3' atom. Get audio_service_type for AC-3 based on bitstream mode in the AC-3 parser and decoder, and vice-versa for the AC-3 encoder. Use audio_service_type to set stream disposition. Add APIchanges entry for audio_service_type. Add audio_service_type field to AVCodecContext for encoding and reporting of the service type in the audio bitstream. configure: in check_ld, place new -l flags before existing ones support @heading, @subheading, @subsubheading, and @subsubsection in texi2pod.pl doc: update build system documentation aacenc: indentation aacenc: fix the side calculation in search_for_ms vp8.c: rename EDGE_* to VP8_EDGE_*. Conflicts: doc/APIchanges libavcodec/avcodec.h libavcodec/version.h libavcodec/vp8.c Merged-by: Michael Niedermayer <michaelni@gmx.at>

FATE Automated Testing Environment
|
||||||
|
|
||||||
|
FATE provides a regression testsuite that can be run locally or configured
|
||||||
|
to send reports to fate.ffmpeg.org.
|
||||||
|
In order to run, it needs a large amount of data (samples and references)
|
||||||
|
that is provided separately from the actual source distribution.
|
||||||
|
|
||||||
|
Use the following command to get the fate test samples
|
||||||
|
|
||||||
|
# rsync -aL rsync://rsync.mplayerhq.hu:/samples/fate-suite/ fate/fate-suite
|
||||||
|
|
||||||
|
To inform the build system about the testsuite location, pass
|
||||||
|
`--samples=<path to the samples>` to configure or set the SAMPLES Make
|
||||||
|
variable or the FATE_SAMPLES environment variable to a suitable value.
|
||||||
|
|
||||||
|
For information on how to set up FATE to send results to the official FFmpeg
|
||||||
|
testing framework, please refer to the following wiki page:
|
||||||
|
http://wiki.multimedia.cx/index.php?title=FATE
|
||||||
|
|
||||||
|
FATE Makefile targets:
|
||||||
|
|
||||||
|
fate-list
|
||||||
|
Will list all fate/regression test targets.
|
||||||
|
|
||||||
|
fate
|
||||||
|
Run the FATE test suite (requires the fate-suite dataset).
|
||||||
|
|
||||||
|
Fate Makefile variables:
|
||||||
|
|
||||||
|
V
|
||||||
|
Verbosity level, can be set to 0, 1 or 2.
|
||||||
|
* 0: show just the test arguments
|
||||||
|
* 1: show just the command used in the test
|
||||||
|
* 2: show everything
|
||||||
|
|
||||||
|
SAMPLES
|
||||||
|
Specify or override the path to the FATE samples at make time, it has a
|
||||||
|
meaning only while running the regression tests.
|
||||||
|
|
||||||
|
THREADS
|
||||||
|
Specify how many threads to use while running regression tests, it is
|
||||||
|
quite useful to detect thread-related regressions.
|
||||||
|
|
||||||
|
Example:
|
||||||
