typedef struct demux_meta_t demux_meta_t |
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).
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.
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= vlc_tick_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_GET_TYPE | Retrieves the demuxed content type Can fail if the control is not implemented. arg1= int* |
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 arg1= unsigned * |
DEMUX_GET_TITLE | Read the title number currently playing. Can fail. arg1= int * |
DEMUX_GET_SEEKPOINT | |
DEMUX_GET_POSITION | |
DEMUX_SET_POSITION | |
DEMUX_GET_LENGTH | |
DEMUX_GET_TIME | |
DEMUX_SET_TIME | |
DEMUX_GET_NORMAL_TIME | |
DEMUX_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_DEFAULT | |
DEMUX_SET_GROUP_ALL | |
DEMUX_SET_GROUP_LIST | |
DEMUX_SET_ES | |
DEMUX_SET_ES_LIST | |
DEMUX_SET_NEXT_DEMUX_TIME | |
DEMUX_GET_FPS | |
DEMUX_HAS_UNSUPPORTED_META | |
DEMUX_GET_ATTACHMENTS | |
DEMUX_CAN_RECORD | |
DEMUX_SET_RECORD_STATE |
The control is never used if DEMUX_CAN_RECORD fails or returns false. Can fail. arg1= bool arg2= string |
DEMUX_CAN_CONTROL_RATE | |
DEMUX_SET_RATE | |
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.
