Error of ffmpeg when output movies using bview on HPC

[HUI WANG]

Dear all,

When I include the view.h and outpout some movies of the simulation on a super computer, I received the following error. I have loaded the yasm, x264, fdk-acc, lame, ffmpeg modules from the HPC's system

I also tried to install ffmpeg myself on the home foder myself using the following compiling command, but I got the same error

 ./configure --enable-shared --enable-gpl --enable-libx264 --prefix=/home/hui/path/ffmpeg/

Does anyone encountered this problem before?

I have encountered this problem before. 

I usually try to increase the fov parameter in view().

Hello Pranav,

Thanks for the reply. I have tried to increase the fov, but it did not work. Have you changed other parameters for fixing this problem? Could you tell me which exact fov number you are using for outputting movies on HPC? 

By the way, I think the problem is not about view.h or fov. For example, this problem exists too when i use output_ppm to generate movies.

   event movie(i++)
   {
   static FILE * fp = popen ("ppm2mp4 f.mp4","w");
   output_ppm (f, fp, n = 1024,  min = 0, max = 1, linear = true);
   }

 Then i got the messages below

Hello Hui, 

Could you please try checking how much space you have available? You might have run out of space.

Thanks, 

Pranav

Hi Pranav,

You mean the storage space of my account on HPC ? I still have plentty of storage memory

It works fine on my desktop. For outputting movies, I use the code below, then load the ffmpeg module from HPC and  then run the simulation. Am I missing something ? 

event movie(i++)
   {
   static FILE * fp = popen ("ppm2mp4 f.mp4","w");
   output_ppm (f, fp, n = 1024,  min = 0, max = 1, linear = true);
   }

Thanks 

Hui

May be you can try these two things.

Change n=256 or smaller.
Also I believe it is "ppm2mpeg > f.mp4". You might be missing >

Hi Pranav,

Thanks for your help. This problem has been solved. 

It's beacuse of the version of ffmpeg on HPC is too.

Dear Hui,

I update basilisk in my PC, still I am getting same errors. How you solved it??

Hello Yashika, 

My problem was outputting pics/movies on a supercomputer. The problem disappeared after updating the version of ffmpeg in supercomputer's system

Cheers

Dear Hui,

I apologies for late reply, (My problem was outputting pics/movies on a supercomputer.) I also had similar problem, I did update 'ffmpeg' in my PC but I am getting similar errors. I was trying to figure out if I could do something else to solve it. Whereas I could successfully generate .ppm on supercomputer system, it worked there. It serve my purpose for now.

Thank you for your kind help.
