Gideros Player (2015.04.08) Not Functioning

antix · April 2015

I have 2 devices, a Nexus4 phone (android 5.0.1), and a Nexus7 tablet (android 5.1)

I have only been testing device playback on my Nexus7. Until today things were going fine and then when I added music I noticed that the music would play once, but not repeat. I thought this was odd because in the local player the music does repeat.

So I updated (dunno what I was using) to Gideros 2015.04.08 and now things have turned to total custard!

When the player starts on the Nexus7 the screen is white, there is no information on the ip, version, or anything else. When the app plays the display turns black and there are no graphics. I know the app is running because the music plays, but of course it does not repeat!

So, I installed the player on my Nexus4 and tested with that. The graphic issues are exactly the same, no damn grahics. However the music does repeat on the Nexus4.

I am totally confused and mildly annoyed because now I cannot test my app on either device. I am more annoyed because the app requires multi-touch which I can't do in the local simulator.

Can anyone assist me in getting the player to again work on my devices? And also I need some help with getting the music to repeat on the Nexus7.

are there some specific settings I need to change somewhere?

No, it's a bug.

@ar2rsawseen has the fix and should (hopefully) be making a new version tomorrow (Sunday).

The simulator does multi-touch btw, I've tested it on two Windows multitouch screens.

Use something like this type of routine to play the music with repeat (on some tablet/tune combinations the repeat flag doesn't work).

music=Sound.new("themetune.mp3")
function restartMusic()
playingMusic:removeEventListener(Event.COMPLETE,restartMusic)
playingMusic=music:play()
if playingMusic then
playingMusic:addEventListener(Event.COMPLETE,restartMusic)
end
end
playingMusic=music:play()
if playingMusic then
playingMusic:addEventListener(Event.COMPLETE,restartMusic)
end

@SinisterSoft, nice, thanks. I'll look forward to that fix,

I still have the issue where there are no graphics on my devices

SinisterSoft · April 2015

That was the fix i'm referring to.

antix · April 2015

@Sinistersoft, Ahh heheh

Damn, now I'll have to kludge in that music code for now I suppose. Will that be resolved in an upcomming patch too?

antix · April 2015

Oh my. I just exported from Gideros Studio, compiled my app in Android Studio, and that doesn't work on either device too. I thought the issue was just with Gideros Player but it seems universal

Oh well I suppose I can do some gardening today instead of programming

hgy29 · April 2015

@antix, if you really need to, version 2015.04.04 should still work, bug was introduced in 04.08. Sorry for that the bug is mine

BTW, gardening is better I think

SinisterSoft · April 2015

@antix - the music bug - I think has something to do with the 'built-in' check for the end of the song being missed. Maybe the routine is looking for something like:

if position==endOfSongPosition then
position=startPosition
end

But in C of course!

When maybe the position pointer sometimes stops just after or just before the end of the song, so maybe that code could be changed to:

if position>=endOfSongPosition-1 then
position=startPosition
end

You see?

Something is odd or different somewhere though because the COMPLETE event fires!

Maybe you should joing GitHub and mark it as a bug ?

antix · April 2015

@SinisterSoff I should join github soon. I have many suggestions for Gideros too. I see what you mean re the music playback, I will experiment once everything is working again in my devices.

@hgy29 Heheh, no worries. I will downgrade tomorrow and see what happens. The weather was not good for gardening today so I spent a lot of time optimizing my texture atlas and writing down ideas for future games

antix · April 2015

Gideros Update 2015.04.12 has resolved my issues with device playback

SinisterSoft · April 2015

The audio was fixed? I'd still use the routine if I was you...

antix · April 2015

@SinisterSoft -oops, no the audio issue is not solved. I meant to say that my apps are now visible on my devices, both through the player and compiled with Android Studio.

SinisterSoft · April 2015

@antix you should try the LuaJIT patch, it gives a nice speed improvement.

antix · April 2015

@SinisterSoft - What is that and how exactly does it work? Does it replace the Gideros Player or something?

SinisterSoft · April 2015

No, it replaced the Lua engine in the player (and 'runtime' if exported).

Here is some benchmarks for standard Lua vs LuaJIT

Ahh, yep I found your other post so will try it soo n ☺

Can anyone help me with the music? I have used your code in my class SinisterSoft but whenever it gets to restarting the music I get an error "attempting to access playingMusic a nil value.. I don't get what is happening. Here is my code..

Music = Core.class()

function Music:restartMusic()
self.playingMusic:removeEventListener(Event.COMPLETE,self.restartMusic)
self.playingMusic = self.optionsTheme:play()
if self.playingMusic then
self.playingMusic:addEventListener(Event.COMPLETE,self.restartMusic)
end
end

function Music:init()
self.startTheme = Sound.new("sounds/start.mp3")
self.optionsTheme = Sound.new("sounds/options.mp3")
self.highscoreTheme = Sound.new("sounds/highscore.mp3")
self.gameTheme = Sound.new("sounds/game.mp3")
end

function Music:on(theme)
if not self.playingMusic then
if theme == "start" then
self.playingMusic = self.startTheme:play(0)
self.playingMusic:setVolume(0.5)
elseif theme == "options" then
self.playingMusic = optionsTheme:play(0)
self.playingMusic:setVolume(0.5)
elseif theme == "game" then
self.playingMusic = self.gameTheme:play(0)
self.playingMusic:setVolume(0.10)
elseif theme == "highscore" then
self.playingMusic = self.highscoreTheme:play(0)
self.playingMusic:setVolume(0.5)
end
self.playingMusic:addEventListener(Event.COMPLETE,self.restartMusic)
end
end

function Music:off()
if self.playingMusic then
self.playingMusic:stop()
self.playingMusic = nil
end
end

Hello, you get playingMusic a nil value, because your device ran out of channels to play simultaneous music files.

Maybe that is why it is also not looping the standard way.

What type of file are you using?
How many files are you playing?

SinisterSoft · April 2015

@ar2rsawseen - how many sound channels should be available - I remember (a long time ago) running out of channels pretty early.

Once a sound has completed playing or stopped - isn't it's sound channel automatically free?

@antix maybe when you call Music:off() and set self.playingMusic to nil then completed event still fires afterwards? If it does then self.playingMusic would be nil at that point?

ar2rsawseen · April 2015

I think 16 or 32, depending on device and yes they should be freed, but there could always be a bug

SinisterSoft · April 2015

32 would be best (if it's not set to that already)....

Also the latency is pretty big. Was there talk once of moving to another lib on Android with a lot less latency?

ar2rsawseen · April 2015

@SinisterSoft yes but it was a paid license software, and the agreement was a revenue share, so now it is not an option.

SinisterSoft · April 2015

ahh, I see.

SinisterSoft · April 2015

Does SoundPool not provide the lowest latency?

SinisterSoft · April 2015

Does the Android version use OpenAL - would OpenSL ES be a better fit?

antix · April 2015

@ar2rsawseen - Thanks. I have only the 4 listed in my code, and one sound effect that is used during the game. My code is based on your music code from your book (which I enjoyed a lot, thanks). So as far as I know, I am only using one channel at any time because when Music:off is called, the channel is released right?

@SinisterSoft - Yep maybe that could happen but I am not calling Music:off at all with my tests. The app loads, and starts the options music, then it tries to restart the options music once it ends and gets the nil error.

Since (I think) I'm only ever using one channel I can't see how it becomes nil

Unless.. whenever Sound.new is called it is allocating a channel?

SinisterSoft · April 2015

Sound.new shouldn't be allocating a channel - it should just load the sound.

loadedDound:play() -- that should be allocating the channel

antix · April 2015

@SinisterSoft - Okay thanks for clearing that up. It still doesn't explain why the error with the nil value is happening, especially since I hsave only one channel allocated.

ar2rsawseen · April 2015

Funny that I did not seem to experience that the built in looping does not work

If you check the same game from the book - Mashballs

Does it happen on your device that the music looping stops?

antix · April 2015

Right now I'm thinking that this must be some issue with the Google Nexus 7. On my Nexus 4 the code works just fine, but on the Nexus 7, it crashes with the "a nil value" error.

antix · April 2015

@ar2rsawseen - Good idea. I tested the MashBalls Clone and on the Nexus 7 the mp3 plays only once then stops. It does not crash with any "nil value" error however.

On the Nexus 4 it works without any issues.

I am feeling more and more that this is an issue with the Nexus 7?
