Andreas Rheinhardt ec5663d0a7 avformat/dashdec: Ensure strings are zero-terminated strncpy only ensures that one does not write beyond the end of the destination buffer; in case of truncation it does not zero-terminate the destination buffer. This makes using it the way it is now in the DASH demuxer dangerous. So use av_strlcpy instead. Also don't write anything if there is no id: The buffer has already been zeroed initially. The DASH testset from the Universität Klagenfurt contains samples with ids that are too long.

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.

libavutil includes hashers, decompressors and miscellaneous utility functions.
libavfilter provides a mean to alter decoded Audio and Video through chain of 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.
