New project opportunity: Media player?

[millim]

Dear community,

OuGeeNucleo 1.0 now ready for download.
It uses still the basic engine, but a fully reworked graphic layer, equalizer, Bluetooth Remote Control (Volume, Play, Pause, Next and Previous Song).

You will find the download link in the head post above.
Hopefully it works for you. In case you face sever issues, please drop me a PM. I do not plan further developments or bug-fixes.

Hello, millim.
You did oustanding work!
Yet I need to test it with my bluetooth headset, but all in all (interface and number of features you implemented) makes me want to buy another odroid go just for music playback in the car.
Thank you!
BTW In help inside the app it is told that A+Left will change play order, but actualy it is A+Right.

[kelbot]

Working quite well here. Excellent work and thank you so much. I'm loving it!

[mad_ady]

Noob here! Can it play internet radio streams as well?

[ddrsoul]

only mp3 from sdcard, it is mentioned somewhere

HI mad_ady

yes, indeed no internet radio at the moment. I am working on this currently, it is really a nice feature. I do not want to go the route of adding the access-point feature. With that one needs always a second device to get local WIFI access on the OG and I see no point for searching and posting IP addresses. It shall be handy with built in SSID discovery and password input feature. Therefore I need virtual keyboard and edit-box support. The radio itself (44.1kHz mp3) is straightforward.

I am targeting to share a firmware around Christmas time.

Regards
millim

[mad_ady]

That's great to hear! Thanks!

I don't think there's a need for that. I think having wifi credentials in a txt files on sd is acceptable.

[millim]

I don't think there's a need for that. I think having wifi credentials in a txt files on sd is acceptable.

Well, sure this is an option. Still I feel uncomfortable having the wifi credentials in the SD card(s) for several reasons. Much more in favour of keeping it somewhat secret in the NVS storage. But this is just a minor point. The main purpose, I have use-cases in mind with ad-hoc usage on different networks. Here preparing the txt-file and storing it on the SD card still requires an additional device like a mobile phone or PC. And when I do have a PC or phone available, why should I use the OG?

That's a good point. If you're at a friend's house or whatever it would be nice to just find and enter credentials on device and start streaming rather than having to fiddle with a phone or computer to get it connected. The credentials on sd card makes sense for something you would only ues at home but this is a different use case.

thank you very much for the link. Really a nice project..

Ever since my last post, I have worked a bit on the radio integration. Network scan/access and credentials input work with virtual keyboard already. So no need of using access point + additional network device (phone, tablet, pc). So far so good.
On the radio itself, I was not able to find a light-weight repository simply supporting Shoutcast/ICYcast + metadata support + http and https + server redirection + PSRAM memory allocation + ESP_IDF (no ARDUINO!). So I have written my own radio client from scratch.It is functional already. I also want to make use of radio-browser.info to browse worldwide radio-stations on the OG directly, which is currently under development. Need to work on memory optimization.

Overall, there are still two/three tricky things to solve. But I am confident to get it done in the next two month.

Please, if possible, allow playback on the integrated soundcard too. Even if it will sound funny, I expect it will be good enough for voice only.

Agree that would be nice as an option. I listen to podcasts and even music over the internal speaker sometimes. It's not too terrible for low volume background music sometime IMO.

[dtrieb]

Yes that's would be a nice option!

[millim]

Yes that's would be a nice option!

Sure, the internal speaker is always the primary sound output device. When the radio player is ready, you will experience no difference, it is the same thing as you would play mp3 from the sd-card. Still, for the first release, I plan to support mp3 only, but this time with different sampling rates (48k, 32k, 22k, 16k, 8k, 44.1k). This set is supported by the SBC, want to go without resampling DSP.

Plan is to use -
A.) .m3u file format for the URLs, what can be selected with the file browser (one single URL per file)
B.) radiobrowser.info browser API with search function using the new virtual keyboard.

The overall concept and the individual modules are ready. Need to glue everting together and hopefully WiFi, Bluetooth, and Display can co-exist without sound glitches.

Hello!
Finally, I gathered myself up and finished my I2S DAC project. I found out that if you switch to EXT DAC in settings then start playing music and press "pause" you stard to hear loud noise that stops only when you continue to play music. Not sure if you are willing to check it, I use bluetooth most of the time anyway.

[millim]

Hi, very nice project

btw. I do have some SMD DACs laying around (from Analog Devices), and I thought also to make such an adapter. Do not have the tools to make it reeeeaaaally small to fit into a small plug. Indeed, I need to order an DAC shield to test I2S output. I try to fix it in the radio update coming soon..

millim

[kelbot]

I have a similar i2s dac board I use sometimes but I don't remember experiencing any popping when paused. I'll test it later and see if it happens with mine too.

[kelbot]

Ok, yes I get the loud noise on pause as well. It happens when paused and also briefly in between tracks when shuffling a large playlist. When listening to a short playlist it doesn't happen.

[millim]

UPDATE: OuGeeNucleo 1.1 (+ WEB RADIO SUPPORT)

Had some time during Christmas break to complete the web radio version. You will find the details in the head post.

millim

[mad_ady]

Thanks for the web radio support! I hope to put my go to good use!

[ddrsoul]

Latest version is not working for me. Bluetooth is not connecting to my JBL GO (it hangs on 1/4 then just returns back to device list). On 1.0 it was working great.
Also, when I try to go into "wifi settings" everything just hangs (i don't get into settings at all). Only reboot helps.

[kelbot]

I've had the hanging issue as well but it seems random. Restarting and trying again a couple times and eventually it worked.

Might be this is related to number of access points? I mean, now I tried to set wifi at the office and it works every time I open this setting. I can play radio via internal speaker.
At home I have HUGE AMOUNT of access points in near surrounding. Will try again this evening.

Also, I can not connect to my TWS bluetooth headset D:

I understand, sorry that it does not functioning out of the box for you. I think it is related to the number of access points. I think if it exceeds a certain number, the app crashes. I can have a look into it you send me the crash log in a private email. On the BT connection issue, I have an option to debug and can work on an update.

Please try the updated version (V1.2) from the head post. The BT should work now. WIFI, I cannot test, should list at least up to 25 proximity networks.

millim

[alektronic]

This is working pretty well, thanks millim!

I also experience the wifi crash, but getting very close to my router and retrying a few times makes it work.

Radio Browser and opening m3u files work.

I was able to link my BT headphones, although the playback is choppy (whereas it is ok through the speaker) - perhaps this is to be expected due to the device limitations.

I'm experiencing hanging in the latest 1.2 version when I select I2S DAC from the Audio Device menu. This happens whether my DAC is plugged in (and working in other apps) or not.

[kelbot]

Yes, this is very impressive and thank you. One small (well hopefully small) request. When scrolling through long lists of songs or radio stations it can take forever and a ton of button presses. Repeating up/down keypresses when holding the button down would be nice.

Holding up/down buttons pressed for ~500ms should work for scrolling. I will try to implement page up/down scrolling when pressing left/right.

Hello millim, thank you for help.
I tried new version. With new install I tried to set WIFI and it always failed as before. Then I changed audio device to "bluetooth" (and bt finally works! thank you!) and this time wifi seting worked! But it was the last time I managed to run it properly. Anyway my ssid and password is already set and I can experiment more. An here what i found:
Speaker output is broken. I mean it can play music (mp3) but: radio with speaker don't play (it fades black than returning back to radio list). Choosing |speaker" in audio devices causes odroid to hang. "Change App" button also causes odroid to hang.
But I don't have any problems when audio device is bluetooth! (except wifi list)
I though I can provide you crash log about wifi list but it is not generating any of it (because app is not crashing). If I can help you somehow to fix it just let me know how!
Also I noticed that equalizer now works properly with bluetooth. Nice!

I thought , if the issue with wi-fi is unclear, maybe you can add an option to input ssid and password by hand in other menu?

I should send you a debug version with WIFI debug enabled. I will try next days to send it in a private mail. Maybe you have some SSIDs, the sorting can't deal with?

An here what i found:
Speaker output is broken. I mean it can play music (mp3) but: radio with speaker don't play (it fades black than returning back to radio list).

Just to clarify: When it fades back, could be that the radio station can't be found or the WIFI is still not ready. Has nothing to do with the audio output device.

Choosing |speaker" in audio devices causes odroid to hang.

This is a known problem, I could not find any solution. In case Speaker is selected again after DAC-OUT or BT, it hangs. DMA does not work, can't be reinitialized a second time.

"Change App" button also causes odroid to hang.

Yes, will fix it soon.

I thought , if the issue with wi-fi is unclear, maybe you can add an option to input ssid and password by hand in other menu?

Yes, good idea as preferred Wifi setting overriding smart scan. I will think about.

[kelbot]

Ah, thanks for the tip about holding the scroll buttons for 500ms. I just wasn't holding it long enough .

[millim]

Update Version 1.3 available (from the head post).

- Fixed WIFI Setup crash on dense WIFI coverage
- Fixed "Change APP" return to firmware.

In general, after installing the APP from SD-CARD I recommend to force a cold boot (switch off/on), so that the NV memory gets correctly initialized.

[ddrsoul]

Hi millimm
now bluetooth+wifi works perfect! I have used it for a week with no big issues. Thanks for fixing everything! Even my own playlists (somafm) are working good.

[dtrieb]

@millimm

Wohuuu!!!

Great your Media Play is soooo great. THANK YOU!!!

One wish, if possible:

Could you add the possibly to add Radio station to a favorite list.
So we could find them faster.

THANK YOU again!

[millim]

Thank you! (More Likes/Downloads will push me motivation in general)

What I normally do is to create a .m3u file with the favourite radio station. Thus, no need to go across the RadioBrowser App once again.
The RadioBrowser URL is printed in the terminal window, when connected to PC/Laptop and chosen listening, anytime.

[millim]

Short update!

GO still alive yeah!

I found some electronic spare parts at one of our local shops. Couldn't withstand to build a docking station for the GO!
Here the results.

during development ...


... and final result


GO-FOREVER

[mad_ady]

That's one pumped-up Go!
