DVD Player
/usr/photon/bin/dvdplayer
The DVD player plugin, dvdplayer, is based on the Xing DVD Player. It plays DVDs and supports:
While playing a DVD, the plugin behaves like a multitrack program. Individual chapters of the DVD represent the tracks.
Calling MvInit() sets the value of MvPluginCtrl_t.MvPluginFlags_t pflags to MV_HASDFLTURL, but this is for the DVD operation. You can still play files using the CMD_PLUGIN_OPEN_URLS command. The URL can be set to dvd on an CMD_PLUGIN_OPEN_URLS to tell the plugin to use DVD mode.
See the Resource Profile Estimates and Library Dependencies appendix.
Valid commands for the DVD player plugin are:
CMD_PLUGIN_ANGLE
CMD_PLUGIN_BOOKMARK_SET
CMD_PLUGIN_CLOSE
CMD_PLUGIN_DIRECT_AUDIO
CMD_PLUGIN_GET_STATUS
CMD_PLUGIN_KARAOKE_MIX
CMD_PLUGIN_KARAOKE_RECORD
CMD_PLUGIN_MENU
CMD_PLUGIN_MUTE
CMD_PLUGIN_OPEN_URLS
CMD_PLUGIN_PAUSE
CMD_PLUGIN_REVERSE_PLAY
CMD_PLUGIN_SCAN_BACK
CMD_PLUGIN_SCAN_FORWARD
CMD_PLUGIN_SEEK_RELATIVE
CMD_PLUGIN_SEEK_TO
CMD_PLUGIN_SELECT
CMD_PLUGIN_SELECT_AUDIO
CMD_PLUGIN_SELECT_DOWN
CMD_PLUGIN_SELECT_LEFT
CMD_PLUGIN_SELECT_RIGHT
CMD_PLUGIN_SELECT_SUBTITLE
CMD_PLUGIN_SELECT_UP
CMD_PLUGIN_SEND_MESSAGE
CMD_PLUGIN_SET_PARAMETER
CMD_PLUGIN_SET_WINDOW
CMD_PLUGIN_SLOW_MOTION
CMD_PLUGIN_START
CMD_PLUGIN_STEP
CMD_PLUGIN_STOP
This sample callback handler is used by phplay to analyze state changes and status information. After verifying that the plugin handle is still valid, the value of the MvEventFlags_t change variable is examined to determine which field of the MvPluginStatus_t const *pst structure is valid.
Values that may be used for MvEventFlags_t change include:
MVS_AUDIO_LIST
MVS_DISPLAY_INFO
MVS_DURATION
MVS_ERRORMSG
MVS_FLAGS
MVS_MEDIA
MVS_PLUGIN_STATE
MVS_POSITION
MVS_SUBTITLE_LIST
MVS_VPSIZE
