progress bar with other infolabels

[nico1080]

Currently the progress bars use VideoPlayer.Time and VideoPlayer.Duration for the video section

However for live TV these infolabel does not work. (at least in my setup with tvheadend and kodi 18.9)
The infolabel PVR.EpgEventElapsedTime and PVR.EpgEventDuration send back the correct infomation.

How can I use theses infolabel for progress bar only in my live TV layout, and keep the previous infolabels for my other layout?
Maybe with the ELEMENT_CB it will work? But I am not sur how it work.
Or maybe override the prog function ? similary to what I have done with the calc_progress function

With the callback framework that's in place, this should already be possible.

The progress_bar() function is used by both audio and video screens. It is the calling functions that are responsible for invoking calc_progress(), passing it either the MusicPlayer or VideoPlayer time and duration InfoLabels.

So, mimicking the structure of that code, you can get progress_bar() invoked with whatever calculated progress is appropriate. The setup would be roughly as follows...

First, ensure the PVR.EpgEventElapseTime and PVR.EpgEventDuration have been added to the VIDEO_LABELS list in the setup.toml file.

In your script, define a new element_* callback function:

def element_livetv_progbar(image, draw, info, field, screen_mode, layout_name):
    # Calculate progress in media, using InfoLabels appropriate for LiveTV
    prog = kodi_panel_display.calc_progress(
        info["PVR.EpgEventElapsedTime"],
        info["PVR.EpgEventDuration"],
        kodi_panel_display.video_dmode.name
    )    

   show_prog = True

   # If the field has a display conditional
   # defined, let's test that to decide if we should proceed.
   if ("display_if" in field or
       "display_ifnot" in field):
       show_prog = kodi_panel_display.check_display_expr(field,
                                      info,
                                      kodi_panel_display.ScreenMode.AUDIO,
                                      kodi_panel_display.video_dmode.name)

   if show_prog:
       kodi_panel_display.progress_bar(
           draw, field, prog,
           use_long_len = (info['PVR.EpgEventDuration'].count(":") == 2)
       )

The above function takes excerpts from video_screens() and video_screen_dynamic().

Add the above callback to the ELEMENT_CB dictionary in the now-usual fashion, naming it whatever you would like (e.g., livetv_prog).

In LiveTV layouts, do not have a prog element within the top-level of that layout's dictionary. Instead, take all of the key/value pairs that you would have used for the progress bar and use them for a new entry within the layouts fields array. It must be named such that a callback occurs to the above function. All of the key/value pairs should end up getting passed through the callback, down to the existing progress_bar() function, which will then draw the bar as usual, using whatever mechanism you specified to calculate the fractional media progress.

I typed the above into github's discussion widget directly, so I'm not sure all of the spaces are entirely consistent, etc. Hopefully, though, you get the main direction I am trying to convey.

Cheers,
Matt
