The VideoLAN Forums

Hello,

Thanks for all the help. In the end, I was not able to include VLC in the experiments. Executing it in a real-time Linux process (scheduled with the kernel module RESCH) generated a lot of errors from the VLC app., even the computer froze sometimes.

Thx for the support...

Regards

One more thing also...

I tried it now and it works, but when I run (a 91 frame long video), the display callback is called more than 91 times... Does VLC repeat the video or?

Regards

Hey thank you so much! But one thing though, is it tricky to render a video? Do you think you could show me a simple example of that... (I will put your name on the article if you want;) ) I want the experiments to be as realistic as possible, so there should at least be some movie being played... B...

I'm writing a scientific article for a journal that will be published in a few months, BUT, deadline for submitting the article is in a few days and the experimental data with VLC would really improve it... Basically we are scheduling applications in multiple levels (like a tree) where the VLC app. ...

Hi,

How did you solve it?

Regards

Thank you,

So it should be something like this:

libvlc_video_set_format(mp, "RV32", 240, 240, 4);

...and what about the 'lock' function?

static void *lock(void *data, void **p_pixels) {
p_pixels = ?
return NULL;
}

Exactly what could I allocate/set to 'p_pixels'?

Regards

Thx for the reply, So I should use something like: libvlc_video_set_format( mp, "RV32", unsigned width, unsigned height, unsigned pitch ); 'width' and 'height' should be the same I guess, what about 'pitch'? Should 'lock' return dummy buffers? Which data-structures should I use? I reused c...

Hi, I'm conducting research in advanced scheduling of video applications, and I have chosen to use VLC for my experiments. I want to collect timestamps of frames (when they were displayed). I see that 'libvlc_video_set_callbacks' could be useful, but I have a problem. I just want to use the 'display...
