Implemented commands and description
43
------------------------------------
44
- command="quit", arg=ignored, returns=NULL
45
Quits the program, just like if the user had pressed the delete
48
- command="switch_mode", arg=GINT_TO_POINTER(enum tveng_capture_mode
49
new_mode), returns=GINT_TO_POINTER(-1 on error, 0 on success)
50
Switchs between different running modes. See tveng.h for valid
54
Not implemented, use the current_mode field in
55
your copy of the tveng_device_info * struct.
57
- command="get_cur_channel", arg=ignored,
58
returns=GINT_TO_POINTER(current_channel).
59
Returns the currently selected station in Zapping.
61
- command="get_channel_info", arg=index
62
returns=tveng_tuned_channel* channel, or NULL if not found.
63
Info about the given channel. Use tveng_clear_tuned_channel(result)
64
when not longer needed.
66
- command="get_num_channels", arg=ignored,
67
returns=GINT_TO_POINTER(number_of_channels).
68
Number of channels in the channel list.
70
- command="set_channel", arg=GINT_TO_POINTER(channel_index),
72
Sets a given channel in the Channel list. The given value is clipped
73
to the nearest valid values.
75
- commmand="channel_up", command="channel_down", arg=ignored,
77
Go to the previous/next channel in the channel list.
79
- command="set_vbi_mode", arg=GINT_TO_POINTER(gboolean init_vbi),
81
Starts/stops Teletext, depending on the value of arg. If arg is
82
TRUE, then teletext is started. Please note that if you stop
83
Teletext, it doesn't restore the previous capture mode, you need to
86
- command="load_page", arg=GINT_TO_POINTER((page<<16)+subpage)
87
Loads the given page in the main window, tries to start TTX if it
88
isn't already on (i.e., if info->current_mode != TVENG_CAPTURE_NONE).
89
Loading all subpages of a page is done by giving the value
90
ANY_SUB to subpage. Example: load_page((100<<16)+ANY_SUB)
