Format I/O context.
New fields can be added to the end with minor version bumps. Removal, reordering and changes to existing fields require a major version bump. sizeof(AVFormatContext) must not be used outside libav*, use avformat_alloc_context() to create an AVFormatContext.

I/O context.

| unsigned int AVFormatContext::nb_streams |
A list of all streams in the file.
New streams are created with avformat_new_stream().
decoding: streams are created by libavformat in avformat_open_input(). If AVFMTCTX_NOHEADER is set in ctx_flags, then new streams may also appear in av_read_frame(). encoding: streams are created by the user before avformat_write_header().
