Re: [Mvpmc-devel] Video in a thumbnail

RIchard, I had very, very similar troubles when I was trying to play
video through http.

The basic snippet I added to move to full screen was

mvpw_set_timer(playlist_widget, NULL, 0);
mvpw_hide(playlist_widget);
mvpw_hide(fb_progress);
video_set_root();
mvpw_focus(root);
screensaver_disable();
mvpw_set_timer(root, video_play, 50);

(You can check out what I did in the audio.c function by searching for
video_play.)

If all things go well you should be back in the playlist after the
video(s) have played since that is where video.c will leave you
assuming you are using similar playlist logic as used for  audio.

I am still planning on looking into why all of this is necessary,
since playing files directly doesn't require it.  I coded this quickly
by trial and error rather then fully understanding the code, and Jon
even had to fix where I killed the audio thread, so I am definitely
not an expert.

[Mvpmc-devel] Programming questions...

[stuart <stuart@xn...>]

Hi Jon...

As I try to unwind MVPMC for the "startup" feature - I am wondering about:

Trying to integrate this feature in your grand scheme of storing all 
this config data in EEPROM.

I would like to emulate the IEE menu because it uses a sort of "radio 
button" approach of selecting options.  It would appear the approach is 
simple and only needs some code added to gui.c around lines 2900 to 3000 
in the settings_select_callback function.

However, the IEE menu in the settings directory does not have a 
"CONFIG_--" define in the config.h file.  So, I am thinking the IEE menu 
does not fit into your grand scheme for later EEPROM storage.

So, following other examples, I have been trying to add code to gui.c, 
config.h and config.c.  But, there are few comments here to hint of what 
to try.

So, question 1: Is the IEE menu short of what you eventually want to 
do? Am I going down the right path modifying config.c to support the 
config structure?:

[Mvpmc-devel] Video in a thumbnail

[Richard Hodson <richard@ho...>]

Hi,

I have made a patch to show a directory full of video
files as part of the file browser. It currently has two
problems.

1/    You hit "play all" or "shuffle play" and you get a thumbnail
      of the video in the bottom right.

In playlist_change() it currently has the lines:

  } else if (is_video(current)) {
    mvpw_set_timer(root, video_play, 50);
  } else if (is_audio(current)) {

and I guess I need something in there to tell either the
video to go full or the filebrowser to go away. Frankly
I can't make head nor tail of controlling the display so far!

2/    When all the videos are finished, I can't see how you detect
      that to go back to the filebrowser screen. Right now it just
      all stops.

I think this is related to my lack of understanding above :-)

 - Richard

I found the issue, I had been using a dongle.bin.config file with

-f /etc/helvB18.fnt

as an option.  I removed that option and every this worked correctly.  I 
don't remember why I inserted that option but it has been like it since 
October.

It is kind of bizarre that that would cause an issue but the tcpdump 
does show that no trafic occurs after the pause.
