Andreas Rheinhardt ea1b71e82f avcodec/hevc_mp4toannexb_bsf: Check NAL size against available input The hevc_mp4toannexb bsf does not explicitly check whether a NAL unit is so big that it extends beyond the end of the input packet; it does so only implicitly by using the checked version of the bytestream2 API. But this has downsides compared to real checks: It can lead to huge allocations (up to 2GiB) even when the input packet is just a few bytes. And furthermore it leads to uninitialized data being output. So add a check to error out early if it happens. Also check directly whether there is enough data for the length field.

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.
