Hi,
just curious, I'd love to see how veejay is running on rpi.
I don't even know if it's possible and not sure at all how I would proceed.

From my non-existent knowledge into this, I understand I need to install gcc-10-arm-linux-gnueabihf or something similar, install all dependencies on the rpi4 and that's all I know.
I'm running debian on an x86_64 host and my rpi4 runs diet-pi, a nice debian derivative.

Many thanks if you have ideas !

Did you try this on rpi4 ?

Hi,
no, didn't try, because I can't figure out clearly the steps to achieve this.
Still open to suggestions : )

The same as usual. If there is any error that stops the configure or build process, just let me know.

$ sh autogen.sh
$ ./configure
$ make
$ make install

I tried several months ago, can't remember clearly the error.
It was something architecture related, some -MARCH parameter maybe...

Currently backing up the rpi and I get back to you.

There it is, at the ./configure step and I don't know what to do here :

Okay, I added the definitions for aarch64 architecture. You can try again ( and we take the next problem )

Sorry for so much French
Won't touch anything now, let me know if you need any file(s) related to this output.

Yes, the first error that happens will be the most useful. You can redirect stderr to a file, this leaves just the errors. However, most likely your platform can't support the assembly included by new_arm.S and it needs to be excluded from the build when your platform is targeted.

Can you run the following C program ?

#include <arm_neon.h>
      int main() {
        uint8x8_t v = vdup_n_u8(1);
        return 0
     } 

$ gcc -march=armv8-a+crc -mfpu=neon -o test test.c && ./test

$ gcc -march=native -o test test.c && ./test

$ gcc -march=armv8-a+crc -o test test.c && ./test

This will test for a SIMD NEON instruction. One of the gcc commands should compile and run with exit code 0

So, my rpi has burnt in flames while building veejay...

Sorry, this is my Friday's poorest joke ! Everything went fine - core, server, client, utils. \o/

Currently watching veejay running loaded with a bunch of avi/mjpeg 640x480 25fps samples + mixing FX, veejay eats roughly 120% of CPU, reloaded about 40%, temperature raising but fine. I need a better cooling system anyway.

About the FX, yes, some of them produce unexpected result :
all overlay type, effectv type produce vertical green lines.
magic tracer produces big horizontal snow lines.
luma based run fine.

chroma based, LVD, produces vertical green lines.

Frei0r plugins from source produce vertical green lines and basically run between 10 and 15 fps.

I'll see how it behaves with v4l2, http/mp4 streams and midi controller but I guess these features will be fine.
No crash observed so far.

I have an HDMI touchscreen plugged to the rpi, but it's only left-click capable so not really useful with reloaded.

Anyway, this is really great, holidays well deserved !
Your pleasure to close this issue : )

Hi Niels,

just rebuilt with latest fixes.

About this ssh trick, you should be able to connect a local reloaded to the remote veejay.
Once connected with -L and 3490:remotehost:3490, your local port 3490 and the remote 3490 will be linked, then connect reloaded to your 3490 port on localhost. The cmdline still needs the -p argument.
Wireguard will be easier to setup if you're not inspired with ssh.

I left a server running in case you're around.

Can you try Normal Overlay and Soft Blur at your next opportunity ?

Both work well.

Not an expert at video processing here, and not familiar with lzo. From my knowledge, lzo is used in many cases but never knew that could be used with live video processing.

EDIT :
Sorry if it feels like a dumb question but could you explain a bit more about these formats you're recommending ?

Question is more like : how do I create video samples in a more veejay-compliant format ?
I know veejay can export to required formats, I guess I should play more with this features but I find it less easy when it's about cutting videos into samples.

And did you have enough of the wonderful 'Comté' and the pretty unique 'Vin Jaune' ?
