◆ demux_meta_t

typedef struct demux_meta_t demux_meta_t

Enumeration Type Documentation

◆ demux_query_e

enum demux_query_e

Control query identifiers for use with demux_t.pf_control.

In the individual identifier description, the input stream refers to demux_t.s if non-NULL, and the output refers to demux_t.out.

A demuxer is synchronous if it only accesses its input stream and the output from within its demux_t callbacks, i.e. demux.pf_demux and demux_t.pf_control.

A demuxer is threaded if it accesses either or both input and output asynchronously.

An access-demuxer is a demuxer without input, i.e. demux_t.s == NULL).

Enumerator
DEMUX_CAN_SEEK	Checks whether the stream supports seeking. Can fail if seeking is not supported (same as returning false). Bug: Failing should not be allowed. arg1 = bool *
DEMUX_CAN_PAUSE	Checks whether (long) pause then stream resumption is supported. Can fail only if synchronous and not an access-demuxer. The underlying input stream then determines if pause is supported. Bug: Failing should not be allowed. arg1= bool *
DEMUX_CAN_CONTROL_PACE	Whether the stream can be read at an arbitrary pace. Cannot fail. arg1= bool *
DEMUX_GET_PTS_DELAY	Retrieves the PTS delay (roughly the default buffer duration). Can fail only if synchronous and not an access-demuxer. The underlying input stream then determines the PTS delay. arg1= int64_t *
DEMUX_GET_META	Retrieves stream meta-data. Should fail if no meta-data were retrieved. arg1= vlc_meta_t *
DEMUX_GET_SIGNAL	Retrieves an estimate of signal quality and strength. Can fail. arg1=double quality, arg2=double strength
DEMUX_SET_PAUSE_STATE	Sets the paused or playing/resumed state. Streams are initially in playing state. The control always specifies a change from paused to playing (false) or from playing to paused (true) and streams are initially playing; a no-op cannot be requested. The control is never used if DEMUX_CAN_PAUSE fails. Can fail. arg1= bool
DEMUX_SET_TITLE	Seeks to the beginning of a title. The control is never used if DEMUX_GET_TITLE_INFO fails. Can fail. arg1= int
DEMUX_SET_SEEKPOINT	Seeks to the beginning of a chapter of the current title. The control is never used if DEMUX_GET_TITLE_INFO fails. Can fail. arg1= int
DEMUX_TEST_AND_CLEAR_FLAGS	Check which INPUT_UPDATE_XXX flag is set and reset the ones set. The unsigned* argument is set with the flags needed to be checked, on return it contains the values that were reset during the call This can can fail, in which case flags from demux_t.info.i_update are read/reset arg1= unsigned *
DEMUX_GET_TITLE	Read the title number currently playing. Can fail, in which case demux_t.info.i_title is used arg1= int *
DEMUX_GET_SEEKPOINT
DEMUX_GET_POSITION
DEMUX_SET_POSITION
DEMUX_GET_LENGTH
DEMUX_GET_TIME
DEMUX_SET_TIME
DEMUX_GET_TITLE_INFO	Todo: Document Warning The prototype is different from STREAM_GET_TITLE_INFO Can fail, meaning there is only one title and one chapter. arg1= input_title_t **, arg2=int , arg3=int pi_title_offset(0), arg4= int pi_seekpoint_offset(0)
DEMUX_SET_GROUP
DEMUX_SET_ES
DEMUX_SET_NEXT_DEMUX_TIME
DEMUX_GET_FPS
DEMUX_HAS_UNSUPPORTED_META
DEMUX_GET_ATTACHMENTS
DEMUX_CAN_RECORD
DEMUX_SET_RECORD_STATE	Todo: Document Warning The prototype is different from STREAM_SET_RECORD_STATE The control is never used if DEMUX_CAN_RECORD fails or returns false. Can fail. arg1= bool
DEMUX_CAN_CONTROL_RATE
DEMUX_SET_RATE
DEMUX_IS_PLAYLIST	Checks whether the stream is actually a playlist, rather than a real stream. Warning The prototype is different from STREAM_IS_DIRECTORY. Can fail if the stream is not a playlist (same as returning false). arg1= bool *
DEMUX_NAV_ACTIVATE	Activate the navigation item selected. Can fail
DEMUX_NAV_UP	Use the up arrow to select a navigation item above. Can fail
DEMUX_NAV_DOWN	Use the down arrow to select a navigation item under. Can fail
DEMUX_NAV_LEFT	Use the left arrow to select a navigation item on the left. Can fail
DEMUX_NAV_RIGHT	Use the right arrow to select a navigation item on the right. Can fail
DEMUX_NAV_POPUP	Activate the popup Menu (for BD). Can fail
DEMUX_NAV_MENU	Activate disc Root Menu. Can fail
DEMUX_FILTER_ENABLE	Enable/Disable a demux filter. Warning This has limited support, and is likely to break if more than a single demux_filter is present in the chain. This is not guaranteed to work in future VLC versions, nor with all demux filters
DEMUX_FILTER_DISABLE
