(strl): list of IP to exclude for source-specific multicast

UDP/TCP input

Register name used to load filter: sockin
This filter may be automatically loaded during graph resolution.

This filter handles generic TCP and UDP input sockets. It can also probe for MPEG-2 TS over RTP input. Probing of MPEG-2 TS over UDP/RTP is enabled by default but can be turned off.

Data format can be specified by setting either ext or mime options. If not set, the format will be guessed by probing the first data packet

• UDP sockets are used for source URLs formatted as udp://NAME
• TCP sockets are used for source URLs formatted as tcp://NAME
• UDP unix domain sockets are used for source URLs formatted as udpu://NAME
• TCP unix domain sockets are used for source URLs formatted as tcpu://NAME

When ports are specified in the URL and the default option separators are used (see gpac -h doc), the URL must either:

• have a trailing '/', e.g. udp://localhost:1234/[:opts]
• use gpac separator, e.g. udp://localhost:1234[:gpac:opts]

When the socket is listening in keep-alive ka mode:

• a single connection is allowed and a single output PID will be produced
• each connection close event will triger a pipeline flush

Time Regulation

The filter uses the time between the last two received packets to estimates how often it should check for inputs. The maximum and minimum times to wait between two calls is given by the mwait option. The maximum time may need to be reduced for very high bitrates sources.
