It can be used in combination with AV_OPT_SEARCH_FAKE_OBJ for examining options.

| int avformat_network_init | ( | void | ) |
Do global initialization of network components.
This is optional, but recommended, since it avoids the overhead of implicitly doing the setup for each session.
Calling this function will become mandatory if using network protocols at some major version bump.

| AVStream* avformat_new_stream | ( | AVFormatContext * | s, | |
| AVCodec * | c | |||
| ) |
Add a new stream to a media file.
When demuxing, it is called by the demuxer in read_header(). If the flag AVFMTCTX_NOHEADER is set in s.ctx_flags, then it may also be called in read_packet().
When muxing, should be called by the user before avformat_write_header().
| c | If non-NULL, the AVCodecContext corresponding to the new stream will be initialized to use this codec. This is needed for e.g. codec-specific defaults to be set, so codec should be provided if it is known. |
