Topic: BASS for ARM Linux

[Jan Rzepiszczak]

Hey,
I need help again. Some time ago Youtube changed something on their servers and now I have some issues with some of the tracks. The biggest mistake is that if I ran my program on PC it runs perfectly but when I ran this same program but on Raspberry Pi v4 some links cause that thread stop on creating Stream from URL:

Code: [Select]

...
 _currentStream = Bass.BASS_StreamCreateURL(track.Url, 0, BASSFlag.BASS_DEFAULT, null, IntPtr.Zero);
...
When I'm copying stream URL and pasting it into the browser, the browser has no problems with playings such files. And of course, when I'm trying to play these tracks on my PC everything goes smoothly and easy. Because the problem is always with some specific files I downloaded it and tried to compare it but they are identical.
Then I remembered that I have a debug version of libbass for raspberry so I tried to collect some logs.
There are logs from trying opening an invalid file:

In this case, it is the end of the file. If I'm trying to load other songs I'm getting output:

And songs can be played.
Unfortunately, links have got expiration dates and are filtered for specific IP addresses so I can't give just paste in because they will respond with 403 error code. But I downloaded two files which I had a problem and one working perfectly.  Link: https://1drv.ms/u/s!AhZzYQaFDepLgrV7gKEsL0g1knJ15g?e=gC6Jl5
Summarizing, links works on PC but this same link freezes the bass library on BASS_StreamCreateURL() method when run on Raspberry Pi 4. Most of the links run perfectly but some of them cause the problem.  And in the end, from time to time "broken" link will run easily without causing the problem, but if I try to play it next time by creating a new stream from this same URL it freezes.

P.S. I'm using radio42 Bass.Net wrapper.

Coincidentally, there was an HTTPS-related ARM Linux bugfix posted yesterday:

   www.un4seen.com/forum/?topic=19073

Please give that update a try and see whether it helps in your case too.

[Jan Rzepiszczak]

I tried to update library but nothing changed at all, the song is played properly in 1 of 30-40 cases. Most of the time it just stuck in creating stream from url for this specifics songs. I'm using webm and opus plugins too, it is changing situation?

[Ian @ un4seen]

OK. I will send you a debug version to get more information on what's happening.

[Ian @ un4seen]

The ARM Linux version of the BASSMIDI 2.4.13 release is up now in the 1st post.

[Harry May]

I want to publish an open source project containing some bass libraries for ARM platform.
For the ease of use I would like to include the libbass...so libraries into my project.
Is this allowed? Or does each user need to search for them on your web site ?

[Ian @ un4seen]

It will be fine to include the BASS libraries with your project, so long as you make it clear (eg. in the documentation) that BASS is not free and the user will need to get a licence if they decide to use it commercially.

[Harry May]

thanks for your answer. That makes it easier for the user. I will put a link to your licensing in the source code and in the GUI.
The project is on github: https://github.com/dj0abr/SSB_HighSpeed_Modem
