Wiz Beta Of Ommpc2X 0.4.0

[Coder_TimT]

OK, tested the Beta 8:

-The volume bar is working: Turning the option "Software Vol.:" to "on" do the job. What's this option for?
-When I go to the settings menu the first time the cpu clock reads "80", what's definitely wrong. But you now can go to "580" max. and can save the value.
-Saving the settings freezes the program and you must restart the Wiz. But the settings are saved. (Edit This only seems to happen when a piece of music is currently playing in the background)
-After saving the settings the icons and album arts in the "Now playing" screen are gone. I found no way to bring them back. (Edit Found it: Album arts must be "false". Strangely the album covers are shown anyway!
-I can confirm sometimes crashes to desktop when updating the db. But the update is done.
-(Edit Changing the skin to "default" you get a crash to menu and Ommpc refuses to start. OK, editing the ommpc.conf manually and change back to "crystal_ts" brings me back to play...

Thanks for the great feedback Stephan. I've been working on this for so long I forget about some of the "issues" that need to be fixed.

• Software vol turns on mpd's internal mixer to control volume as opposed to using the hardware mixer. It was introduced on the f200 to deal with the issue of not being able to turn it down low enough. On a real system, it would be used to have application specific volume. MPD would internally adjust it's output volume while leaving the system volumes(Master and PCM) alone. So when uses the software mixer, MPD takes care of the volume itself and thus knows what it is. When using the hardware mixer, MPD expects to be controlling the PCM volume, but apparently the volume changes are happening at the Master level and the PCM volume never actually changes, so the volume bar doesn't change. In other words, I think another weird GPH quirk.
• This is caused by the fact I set the speed to 533 as an initial default, but 533 isn't an option in the list. So it just shows the first list item. Once you have a value from the list selected, it should be fine...
• This is the long time, main problem I've always had with mpd on gp2x hardware. I have 1 "good" build of mpd that I keep bringing forward on the gp2x that is somewhat well behaved. It only locks up half the time. All my new builds are worse. I will have to look into this again and see if I can figure anything out. Until then I will make some changes to try and minimize the impact on the wiz...
• Show Album Art is actually a depreciated option, I need to remove it...
• If I'm going to have that default there still, I should fix it up where it works...probably just remove it...

Again, thanks for testing.

Again, thanks for testing.

Gladly. Thank you for your work on a platform you don't own.

Tim, now I installed the GP2x version on my F-200 to better track down Wiz specific bugs. See my post in the GP2x section. But your last post explains a lot...

Regards,
Stephan

Notice: Personally I prefer the english translation, but I think there're some people who will might get use of it.
Even not using my own translaton it's a nice feature to support different languages.
I find it really difficult to translate some words, as nobody here uses a German word for "Playlist".
Bindings are not translated yet (Are they used anyway?)
The same apply to the virtual keyboard. (I think there's not enough space)
German Umlauts are not supported. Do you want me to leave them out?
Some texts are very long now. Drop me a line if you want me to shorten the words.

 

[Coder_TimT]

Awesome, a translation! The file Is being read as utf-8 so I believe special characters such as umlauts should work if saved as utf-8? I live in the land where simple ASCII still rules so I don't have much experience with doing so... But I think I remember testing that and it working...

Binding are used in the key binding lists that are displayed when you press the start and select buttons together...

Keyboard is still hardcoded, so nothing to do there yet... My bad, apparently I did include the keyboard...hmm...I guess throw what you would expect there and we can see what it ends up looking like...

I'll take a look and see what changes we might can make...for things like playlist just put what you would expect to see in the context of a music player...


Also there is a new build labeled 0.4.1.

• Turns on software vol by default
• Polls mpd more frequently in an attempt to make ui more responsive
• Removed art option
• Changed CPU clock to be 100-600 in approx. 33.3333mhz increments
• New build of mpd I'm hopeful will be a little more tolerant of CPU speed changes. Positive results on open2x test.
• Hid default skin dir in option list.

[sbock]

Short test, not much time. Tomorrow more:

Looks good. The settings menu now shows cpu 533/200 opening it the first time. This is correct.
Only problem I found: Changing a value (not the speed), saving the settings, closing Ommpc and starting it again. Now looking at the settings: cpu 65/100 (never touched them). These values are false, because touchscreen is still accurate. Now you can even see the entry "Show Album Art" which wasn't there before saving. So I think there is a bug when saving the settings...

(Edit This bug only happens once. I try to find out why...

 

[sbock]

OK, made some extensive tests now: Good work, Tim! The new version is now a lot more stable and useable. The crash when updating the db is there, but it's now very seldom. The crash when saving the settings is gone. I found this strange bug mentioned in my last post. But only one time. Will examine further...

Now recapitulate what we have:

-Good touchscreen support at default speed. Even the virtual keyboard is very good to use this way. Rest of the controls works.
-Hold modus works with underclocking. After hold ended touchscreen is accurate again.
-Very good volume range.
-OGG, MP3, MOD, ID3 display, library functions, repeat the music at the same place when exiting all work great.
-Album art works (There is a little bug that the album art is sometimes not shown at the first music you play. Skipping forth and back and it's there. This bug is also on the F-200 0.4.2 version)
-Detach client ends in crash (black screen), when music plays at the background.
-Nasty screen flickering at: the settings menu, the virtual keyboard.
-Response of the player is OK. I think the F-200 reacts a little faster, but I hardly would call it a problem of Ommpc. I think it's a Wiz problem.

Hey Stephan, if you get the chance, could you try the attached build and see if compiling with the SWSURFACE flag makes any difference with the UI repsonse. Thanks.

Also, is the flickering only on the setting screen with the keyboard(you can also get the keyboard saving a playlist/bookmark)? And is it only at the top of the screen where the title is? And does it happen while there is actually a title being displayed?

 

[sbock]

I would call it slightly better but it's really hard to tell.

I tracked the flickering problem: It's only flickering when you choose a character via touchscreen or the buttons for a few seconds. It's pretty good when you don't do anything. Could it be the little picture on the left top displaying the chosen key? And yes this problem occurs with all virtual keyboards.

It's this screen I mean where you can also see some flicker. This flicker is steady even if you do nothing.

The most flicker is on the highlighted bar. In this case "Install Path".

Any difference in flicker on the settings page with the SWSURFACE build?

I believe you see the flicker on the keyboard and the settings page because the screen is actually redrawn often at those times. Most of the time, we don't actually re-draw anything unless something has changed and needs refreshed. I think the main culprit is going to be the slow 20fps I refresh at so as not to use alot of cpu with the UI. I'll research some of the other wiz flicker threads and then probably put together a couple of builds that refresh at a different rate, just to see if it makes any difference...

 

[sbock]

Any difference in flicker on the settings page with the SWSURFACE build?

Nope.


I tried to fiddle a little bit with notaz display timing tool but no success..

Another test build, defaults to 10fps. Accepts a new config file item "fps=??" to be manually added to the ommpc.conf file. So sometime you're feeling bored, you can try different values to see if it helps/hurts the flicker any...

 

[sbock]

Fiddled around with this, but no change at all. The performance isn't affected either. No matter if a choose 1 or 120fps.
I load the batteries of my camera and try to upload a little movie so you can get a better idea of the problem...

 

[sbock]

I updated the German language file. Tested it with utf-8 and now the umlauts work fine.

I'm going to attach another file that outputs the target fps because there should have been a definite noticable difference in the fps. 1fps should have been unusable with massive delay between button presses. You probably wouldn't notice much at the higher fps, but some things like the display current key in the top corner on the keyboard screen should disappear quickly as that isn't framerate limited in any way...

Also, found issues in my handling of the utf-8 file. The non-ASCII characters aren't showing up correctly...which kind of defeats the purpose of it being a utf-8 file.

One more thing, in regard to "Detach Client", can you check the output and see if it exits cleanly. I'm thinking it does, but something funny is going on when it tries to reload the menu while music is playing...

 

[sbock]

Detach client without muic playing:

Keyboard=32768state=1, keysym->sym=0End status polling thread
End art-loading thread

Detach client with music playing:

You're right: The Wiz don't crash, it's the menu. I can still control the Wiz via RS232. I call the menu. I hear some music and the menu crashes again.


Here's a complete log successfully starting and closing Ommpc:

So the fps parameter is loaded. Can't see any change with flickering/performance yet, but will do some more testing.
My German translation can now be seen in the main menu at the bottom of the icons. But you're right utf-8 is messed up.

[Edit:] The fps parameter work! I tried values from 1- 120 and you now see a change in performance and flicker.
Testing now...

I can that the player supports covers. Do those have to be embedded or do just have to the cover in the directory where the mp3 file is?

It doesn't do embedded, so it needs to be a file in the directory...Looks for AlbumArt.jpg, AlbumArtSmall.jpg, Folder.jpg, then just tries to grab the first jpg it comes to in the folder... Probably need to reexamine that list, but that is the current behavior.

Doesn't only look for jpg or can it display png?
