Andreas Rheinhardt b93ed5c28e avformat/fitsdec: Don't use AVBPrint for temporary storage Most of the data in the temporary storage ends up being returned to the user as AVPacket.data, so it makes sense to avoid using the AVBPrint for temporary storage altogether (in particular in light of the fact that the blocks read here are too big for the small-string optimization anyway) and read the data directly into AVPacket.data. This also avoids another memcpy() from a stack buffer to the AVBPrint in ts_image() (that could always have been avoided with av_bprint_get_buffer()). These changes also allow to use av_append_packet(), which greatly simplifies the code; furthermore, one can avoid cleanup code on error as the packet is already unreferenced generically on error. There are two user-visible changes from this patch: 1. Truncated packets are now marked as corrupt. 2. AVPacket.pos is set (it corresponds to the discarded header line, 80 bytes before the position corresponding to the actual packet data). Furthermore, this patch also removes code that triggered a -Wtautological-constant-out-of-range-compare warning from Clang (namely a comparison of an unsigned and INT64_MAX in an assert).

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.
