Define Documentation

#define DELAY_LONGTEXT

Value:

N_("Pictures coming from the picture video outputs " \
        "will be delayed according to this value (in milliseconds, should be "\
        ">= 100 ms). For high values, you will need to raise caching values." )

#define DELAY_TEXT   N_("Delay")

#define DEST_LONGTEXT

Value:

N_( \
    "Name of the destination bridge-in. If you do not need more " \
    "than one bridge-in at a time, you can discard this option." )

#define DEST_TEXT   N_( "Destination bridge-in name" )

#define ID_LONGTEXT

Value:

N_( \
    "Integer identifier for this elementary stream. This will be used to " \
    "\"find\" this stream later." )

#define ID_OFFSET_LONGTEXT

Value:

N_("Offset to add to the stream IDs specified in " \
        "bridge_out to obtain the stream IDs bridge_in will register.")

#define ID_OFFSET_TEXT   N_("ID Offset")

#define ID_TEXT   N_("ID")

#define NAME_LONGTEXT

Value:

Value:

#define PLACEHOLDER_IFRAME_LONGTEXT

Value:

N_( \
    "If enabled, switching between the placeholder and the normal stream " \
    "will only occur on I frames. This will remove artifacts on stream " \
    "switching at the expense of a slightly longer delay, depending on " \

#define PLACEHOLDER_LONGTEXT

Value:

N_( \
    "If set to true, the bridge will discard all input elementary streams " \
    "except if it doesn't receive data from another bridge-in. This can " \
    "be used to configure a place holder stream when the real source " \
    "breaks. Source and placeholder streams should have the same format. " )
