Jukebox Plugin

[brturn]

Sub,

I've tracked two bugs down to the core music playlist, if you could add these to your list:

- Pressing Stop clears the playlist. Should leave playlist alone and instead just move to the beginning of the current track and pause.

- Appending a track causes the currentIndex to reset to 0 and the first song to begin playing again. Should leave the current song playing and not affect the current index. Only append a song to the end of the playlist.

Still no MVP here, so testing will be delayed a bit.

Thanks!

I've adjusted AddAudioFileToQueue(string file) so that it doesn't reset the queue pointer. PlayAudioFiles(Queue files) will still reset the queue and pointer.

On the stop thing, I'll need to think about that. Its currently operating as designed, which is also the way I like to use it.

Sub,

Thanks! Didn't realize Stop was working as designed. The current behavior is acceptable to me, assuming there is a pause button present on the remote (or I can take over stop and call pause instead).

Hi Bryan,

If you need anyone to do any testing on the MVP side whilst you wait for yours to arrive, just let me know.

jeffcora,

Help with testing would be great. Are you a developer or a user? Specifically, I need to know what does/does not work between the two versions so I can track down what is causing that difference.

- Does the database auto-load?
- Does the first random song get selected & begin playing?
- Does the screen-wipe animate (albiet slowly)?
- Does the currently playing track display correctly the first time?
- .. the next time?
- Can you use the remote to navigate the UI? Is it usable, or is there a design issue which needs to be worked out?
- Can you pause, next-track, and prev-track easily?
- Can you find and select tracks easily?

If you are a developer, I've been told that there is a .NET error message on the PC when the Jukebox stops working. If you could copy me the message and locate where the .NET framework is throwing the exception from (class/method).

Anyone is encouraged to help out! That's why I release the source code along with the plugin.

Thanks,
--Bryan

Hi Bryan,

I’m just a user, last bit of code I did was years ago so afraid it doesn’t mean much to me. Feedback from using the MVP, which hopefully might help you see what’s going on at the MVP end

Quote[/b] ]Does the database auto-load?

I believe it does but just doesn’t show it. When you start the Jukebox it looks like it just freezes with “Building Music Database, please wait…”, and directly below it “Now playing”. underneath all this you can just see the directory number. Database Build shot. However, after about 30 secs it starts to play a random track. You can then press a key and start to navigate through the directories and files. During the DB build it is possible to press the vol keys, and that seems to update the screen to speed the build and get to the File Selection screen, so it looks like a display issue.

A similar type of thing happens on the PC end for me but it's displayed correctly though. If left alone the database build takes 30 secs and the directory count jumps up 20 at a time till it hits about 620 for me. However, if during the database build I press the vol up I can get the build done in about 6 secs, like the button pressing is updating the screen? (BTW I have an AMD3000 so not a particularly slow machine)

Quote[/b] ]Does the first random song get selected & begin playing?

It does. However it doesn't display the current track, it just continues to show “None”. Pressing the stop key stops the current track, and a new one is started.

Quote[/b] ]Does the screen-wipe animate (albiet slowly)?

As I don’t believe that the screen is being updated properly it hard to say. Basically I don’t think that the screen ever changes from file selection mode so there is no animation to be seen.

Quote[/b] ]Does the currently playing track display correctly the first time?

No, the current playing track is never updated, None is displayed all the time

Quote[/b] ].. the next time?

Same as above

Quote[/b] ]Can you use the remote to navigate the UI?  Is it usable, or is there a design issue which needs to be worked out?

Yes, you can use the remote fine, navigate through directories and tracks, select tracks and do filters. However, selecting a track shows it being selected, but it never gets played, it just continues with random track playing and the playlist is never built.

Quote[/b] ]Can you pause, next-track, and prev-track easily?

You can pause the random track, press play to continue, pressing next-track sometimes selects a new random track, pressing previous will go back to the last random track played. Pressing stop, stops the current track and a new one is selected.

Quote[/b] ]Can you find and select tracks easily?

Yes, all like at the PC end, but the playlist isn’t actually built.

.NET:

.NET errors seem to appear all the time, but hard to track down exactly what action causes it and it doesn't necessarily stop the MVP. A very common one is “The object is currently in use elsewhere”, details of which I’ll email direct to save pages of postings.

Hope this help a bit.

Quote[/b] ]there is no animation to be seen.

I've had a similar problem with animations on the MVP when writing a slideshow plugin.

The problem is that on the MVP, when the GBPVR screen bitmap changes, if it is not directly caused by a button press on the MVP remote, it will not get pushed to the MVP.  (which is why jeffcora reports pressing the volume buttons on the remote in order to make the interface move on.)

I don't know whether this is Hauppauge or Sub's problem.

Fixed up the Jukebox (now v4) for GB-PVR v18.  Change log is below.

http://www.fractalscape.org/jukebox/index.html

I'm working on testing with the MVP, I have fixed the major crash bug but the interface still does not respond well.  I'll post more as I learn them.

Here's the v4 change log:
15-Jun-2004 : MVP should not crash anymore (but may not work well).
15-Jun-2004 : Folder image is displayed more prominently.
15-Jun-2004 : Random selection will not play an already selected song.
15-Jun-2004 : Modified playlist display to show track lineup, including previous two tracks.
15-Jun-2004 : Added support for folder.jpg (in addition to default.jpg).
15-Jun-2004 : Selection dots are cleared when playlist is cleared.
15-Jun-2004 : Add multi-directory support with GB-PVR v18

Found some MVP issues and corrected them. Still not working like the PC.

Current Issues:
- Not given a redraw if I don't accept a key (such as the skip forward/back key).
- Currently playing song info appears to be empty (trackDuration and playbackPosition are always zero).
- No way to force a redraw to update currently playing songs, etc.

Added a config flag for continuous updates, turn this off if you are using the MVP, this is what was causing abysmal GUI response.

Oh.. I added a feature that I forgot to put on the readme: Press the Green button to switch to Now Playing mode.

Version 5
15-Jun-2004 : Added "Continuous Update" config flag.
15-Jun-2004 : Fixed several bugs on MVP.

With GBpvr 0.18i and Jukebox v5 I can only get one of my two music dir's I have set in the config app. I only get the first one, and I can't "go back" out of that dir.

In random mode it playes songs from both dir's.
