Andreas Rheinhardt 78169f397d avformat/wtvdec: Fix signed integer overflow Happens when length > INT_MAX / 2; use unsigned for the computation, but restrict the value to INT_MAX, because avio_get_str16le() accepts an int as buf_len argument. Notice that it can happen that the string read by avio_get_str16le() is truncated in this case.

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.
