for_headernon-zero value tells function to work until it gets notification from the server that playing has been started, otherwise function will work until some media data is received (or an error happens)
Returns
0 for successful operation, negative value in case of error

static int inject_fake_duration_metadata ( RTMPContext rt)
static

Insert a fake onMetadata packet into the FLV stream to notify the FLV demuxer about the duration of the stream.

This should only be done if there was no real onMetadata packet sent by the server at the start of the stream and if we were able to retrieve a valid duration via a getStreamLength call.

Returns
0 for successful operation, negative value in case of error

static int rtmp_open ( URLContext s,
const char *  uri,

)
static

Open RTMP connection and verify that the stream can be played.

URL syntax: rtmp://server[:port][/app][/playpath] where 'app' is first one or two directories in the path (e.g. /ondemand/, /flash/live/, etc.) and 'playpath' is a file name (the rest of the path, may be prefixed with "mp4:")
