Fields

av_class: *const AVClass

A class for @ref avoptions. Set by avformat_stream_group_create().

priv_data: *mut c_void

index: c_uint

Group index in AVFormatContext.

id: i64

Group type-specific group ID.

decoding: set by libavformat encoding: may set by the user

type_: AVStreamGroupParamsType

Group type

decoding: set by libavformat on group creation encoding: set by avformat_stream_group_create()

params: AVStreamGroup__bindgen_ty_1

metadata: *mut AVDictionary

Metadata that applies to the whole group.

• demuxing: set by libavformat on group creation
• muxing: may be set by the caller before avformat_write_header()

Freed by libavformat in avformat_free_context().

nb_streams: c_uint

Number of elements in AVStreamGroup.streams.

Set by avformat_stream_group_add_stream() must not be modified by any other code.

streams: *mut *mut AVStream

A list of streams in the group. New entries are created with avformat_stream_group_add_stream().

• demuxing: entries are created by libavformat on group creation. If AVFMTCTX_NOHEADER is set in ctx_flags, then new entries may also appear in av_read_frame().
• muxing: entries are created by the user before avformat_write_header().

Freed by libavformat in avformat_free_context().

disposition: c_int

Stream group disposition - a combination of AV_DISPOSITION_* flags. This field currently applies to all defined AVStreamGroupParamsType.

• demuxing: set by libavformat when creating the group or in avformat_find_stream_info().
• muxing: may be set by the caller before avformat_write_header().
