full exposure of miniaudio-functions!
native QOA and QOI-implementations (may be easy, as infratec already posted the appropriate code...)

thanks, I took a quick look at the sources on github and they appear as one line.
but It copies and pastes into ide fine.


Thanks for pointing that out, idle!

Yeah, nice. Of course, the files were fine on my machine. But Github Desktop managed to make them a one-liner. That would be great to ...

Hi there,

I’m doing a bit of Christmas cleanup by open-sourcing code I wrote over the years. So, for starters, here’s my ServQLite (which I wrote in the 2010s). It’s an (academic) implementation of an SQLite server. I’m sure you’ll find interesting possibilities for using it :-)

Hi there,

maybe I didn't use the right search terms. However, I hope you can help me!

I am building a small Audio / Video-player based on a Raspberry PI 4, the official 5" Touch-Display and HDMI-output. I will have a 32gb micro-sd and a 4tb usb-attached ssd.

I found the install-hints by mk-soft ...

Hi Idle,

great news!

My take on this is here: https://www.purebasic.fr/english/viewtopic.php?t=86166 , but I never figured out how to play audio.

I tried your Code on MacOS, but "Line 118: Structure not found: WAVEHDR.". Hope you get it to work with MiniAudio :-)


I have a fix in mind ...

native MP3 decoder command would still be much nicer

But the Movie lib is native. Why add another library that does the same thing?


MP3-decoding is already a part of Miniaudio. I think, Purebasic should have separate libs for movies and audio. Playing mp3 with the movie library is more like ...

+1

Would be great to have this one. @infratec: A few years ago I coded my own music player. With the movie library you have to check for MP3, FLAC or OGG for every file and use the appropriate command. UseMP3SoundDecoder() would have some advantages in this field

Hi there,

tried your code with MacOS 15.4.1 with an M2 Max.
It crashed after debug-output "Main: Resume Task1" in line 35 of PBCoroutines.pb

Hi there,

please have a look at this as well: We started discussing the audio-topic
Would be great to join forces in audio-related topics to improve PureBasic further!

And how sounds your CreateSound :?:

What should be inside of the sound?
How you want to specify the sound curve?

At the moment your CreateSound() can create an empty sound which returns silence.

To make something lke that universal, you need a lot of stuff around.
This would result in a ...

Hi there,

I'd like to propose new options for working with sound. Since PB switched to the miniaudio-lib, it might be possible :-)

What, if we could edit audio like images? I mean, do something like (with a better named command than StartSounding():


define mySound = CreateSound(#pb_any, 2000 ...

Maybe someone has information on how to access the raw audio-data from a wav-file "loadsound-ed" or "catchsound-ed" with Purebasics Miniaudio?

I figured out how to apply a ring buffer (or circular buffer). But, I would most certainly need access to the raw sound-data.

Hi all!

I almost made it! Have a look at the repo under https://github.com/foodsnacker/pb_play_mpeg .
The source can decode an mpeg1 and play the video-part - unelegantly using an ImageGadget, but it proves the point.
You can export the single frames as images as well and export the audio as raw ...

Shouldn't the loop look like this:

Debug "Video-Resolution: " + Str(width) + "x" + Str(height)

*frame = plm_decode_video(plm)
While *frame
i + 1
Debug "Frame " + Str(i) + " decoded"
*frame = plm_decode_video(plm)
Wend

Without plm_decode(mpeg)


Oh, no!!! You are (partly) right. My bad
