Rockbox for iBasso DX90 dual boot with Mango (Stock Firmware) - Page 14

post #196 of 1288

Rockbox has very slow responsiveness when browsing through the folders. It's really hard to scroll to the end of the list. Is it a way to make it better in settings?

Now that you mention it... I noticed that as well today. Never had problems with the other Rockbox firmwares...

For the aceleration if you press the buttons to scroll (physical or touchscreen,if the theme has this) there is "scroll speed acceleration" in the settings, but it is already set to speed up every "1s" which is the maximum.

Just tested it again after resetting the rockbox settings. Everything is fine now. Something was wrong with my settings...

Ok, it wasn't the settings...

 

@headwhacker : With your latest Rockbox version the screen gets slow and a bit unresponsive when playing back a song and browsing through the database at the same time. As soon as I stop the song, navigation is smooth again. Is this a new bug or has it always been like that?

Is it slow while music is playing? Or slow even if not?

It's slow only while music is playing.

Anyways it's all up to you, it's your baby. I'm only making suggestions... smily_headphones1.gif

Actually, my intention was to point you to sduck's collection of themes he shared in a zip file. I included the 2 themes just to give the default build few options other than cabbie2 (which I'm already sick of).

Since theming is a very personal thing, it should be up for the individual to maintain his own collection in a zip file. The rockbox folder in DX50/90 is still the best way to add themes.

Anyway both centreArt and ipodwidgets are downloaded from rockbox themes page under iPods, you can easily include both in your personal zip file.

Aren't too many buts to call it bit perfect? :tongue_smile:

I think this is a much clearer picture

 

From tinyalsa source in Rockbox

 

static const snd_pcm_format_t format = PCM_FORMAT_S16_LE;    /* sample format */
static const int channels = 2;                                /* count of channels */
static unsigned int rate = 44100;                       /* stream rate */

 

But then you can programmatically set the sample rate by reading the file and assign the rate.


I didn't know that, because before I only read Android port source code.

 

But if it is as such, why not to update the format from the file as well? I understand that 24-bit values may create problems for DSP calculations (EQ etc.), but it could be converted to 32-bit to avoid problems...

Meanwhile...

 

Another Russian here, medmitry, who is active in DX50 thread, has developed a boot launcher to switch some options for his firmware mods. The good of his launcher is that it starts not every power on, but only if lock switch is turned on. The launcher should be compatible with DX90. I think, it would be good to implement RB-Mango selection using his software.

Funny thing is iBasso use  Andoid as their base for the FW. But stripped it down to the point that it's just a Linux with native audio drivers/codec and their own player (Mango).

 

Ironically Ilia (the author who ported rockbox to DX50), did the same thing. Used the Android target from Rockbox's git repository and strip it down some as well and use tinyalsa instead of alsa. From the looks of it is a straightforward pcm data being read from a file and written/sent directly to the DAC without extra sauce in between.

 

The more I look at the source the more it becomes interesting. Like you mentioned, I also think enabling 24-bit is just as easy as changing the format variable. Or not.

 

I will give it a try and see what happens.

It would be everything I need. And solving crackling issue.

I think it's similar to what cholero has been doing on the rockbox side on DX50.

I get a panic when I start playback with Automatic Resume option enabled. Any ideas?
