Andreas Rheinhardt 4a6aece703 fate/ffmpeg: Fix shortest tests The mpeg4 encoder is slice-threaded and its output depends upon the number of threads used. Therefore all tests of this encoder use a hardcoded number of threads (ENC_OPTS in fate-run.sh contains "-threads 1"; only the vsynth%-mpeg4-thread tests override this for the mpeg4 encoder, but they also use a hardcoded value to be consistent across different systems); only the new shortest and copy-shortest[12] (implicitly due to the sample used) tests don't and this leads to FATE-failures. Fix this by explicitly setting the thread count. Also switch the shortest test to framecrc, because hashing side data is itchy even though the side data used here (AV_PKT_DATA_QUALITY_STATS) has a defined endianness.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

libavcodec provides implementation of a wider range of codecs.
libavformat implements streaming protocols, container formats and basic I/O access.
libavutil includes hashers, decompressors and miscellaneous utility functions.
libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
libavdevice provides an abstraction to access capture and playback devices.
libswresample implements audio mixing and resampling routines.
libswscale implements color conversion and scaling routines.

Tools

ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
ffplay is a minimalistic multimedia player.
ffprobe is a simple analysis tool to inspect multimedia content.
Additional small tools such as aviocat, ismindex and qt-faststart.

Documentation

The offline documentation is available in the doc/ directory.

The online documentation is available in the main website and in the wiki.

Examples

Coding examples are available in the doc/examples directory.
