Xiujun Wang 0f3d20ebf6 avformat/cavsvideodec: reduce probe score for prefixed streams

cavsvideo_probe() returns a high score whenever it finds a valid
sequence and picture start code, even when the sequence header appears
only after unrelated leading data. This can make valid JPEG files probe
as CAVS.

Keep the high score when the sequence header is at the start of the
probed stream. Otherwise return AVPROBE_SCORE_EXTENSION / 2 so stronger
probes can win.

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
