A class for logging and AVOptions.

Set by avformat_alloc_context(). Exports (de)muxer private options if they exist.

Definition at line 946 of file avformat.h.

Referenced by avformat_get_context_defaults(), and avformat_open_input().

Can only be iformat or oformat, not both at the same time.

decoding: set by avformat_open_input(). encoding: set by the user.

I/O context.

decoding: either set by the user before avformat_open_input() (then the user must close it manually) or set by avformat_open_input(). encoding: set by the user.

Do NOT set this field if AVFMT_NOFILE flag is set in iformat/oformat.flags. In such a case, the (de)muxer will handle I/O in some other way and this field will be NULL.

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().
