• FFmpeg Quicksync Encoding Increasingly Consuming Memory

  14 août 2015, par Hfcnat Hfcnet

  [h264_qsv @ 006c7c80] Timeout, device is so busy
  frame=98544 fps= 21 q=-1.0 size= 934528kB time=00:54:47.40 bitrate=2328.8kbits/
  s dup=1838 drop=0

  when there’s no memory left on the system, the encoding process starts to go slow and eventually stops, any advice ?

  command :

  ffmpeg -i "udp ://239.101.1.4:10114 ?fifo_size=120000000" -c:a libvo_aacenc -ac 2 -c:v h264_qsv -g 24 -b:v 5000k -minrate:v 4500k -maxrate:v 5000k -bufsize:v 4000k -filter:v yadif -f mpegts "udp ://239.101.1.15:11115 ?pkt_size=1316&ttl=64&buffer=1000000" -loglevel debug

• Piping ppm files to ffmpeg to create movie in c++

  15 août 2015, par chasep255

  I want to create a movie of a zoom on the Mandelbrot set. To do this I want to create image data in the ppm format and then pipe it into ffmpeg using popen. The following command works if I first save the ppm to my disc and then run ffmpeg through the terminal.

  ffmpeg -i out.ppm -r 1/5 out.mp4

  Here is what I am trying to do in code.

  FILE* p = popen("ffmpeg -i /dev/stdin -r 1/5 out.mp4", "w");
  
  ppm_pipe(p, pix_buffers[0], w, h);
  
  fclose(p);
  
  ...
  
  void ppm_pipe(FILE* f, unsigned char* pix, int w, int h)
  
  {
  
      assert(fprintf(f, "P6 %d %d 255\n", w, h) > 0);
  
      size_t sz = 3 * (size_t)w * (size_t)h;
  
      assert(fwrite(pix, 1, sz, f) == sz);
  
  }

  I get the following error message.

• Uploading video with Rails/Paperclip to Heroku/S3

  17 octobre 2015, par Corey Tegeler

  I’ve been failing at uploading a video in production mode on Heroku for way too long, testing local works great with resizing and thumbnail creation. Images also work fine going to my S3 bucket, so the credentials are all okay.

  Here are the logs I usually get from the code used below. Incidentally, the attempt right before I got these logs (without changing any code and using the same test video), the video made it to AWS, just without the resizing or thumbnail creation. But that was the only time I have even made it that far, and this failed upload and 500 error immediately happened after.
