static int rtmp_parse_result ( URLContext *  s, RTMPContext *  rt, RTMPPacket *  pkt  )

static

Parse received packet and possibly perform some action depending on the packet contents.

Returns

0 for no errors, negative values for serious errors which prevent further communications, positive values for uncritical errors

static int get_packet ( URLContext *  s, int  for_header  )

static

Interact with the server by receiving and sending RTMP packets until there is some significant data (media data or expected status notification).

Parameters

s	reading context
for_header	non-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, int  flags  )

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:")
