• -shortest is not working while looping audio with amovie in FFMPEG

  18 juin 2019, par Nikunj Paradva

  Here input is two video total 40 second, i am concate that and speed up 4x,then video duration is 10 second,

  audio input duration is dynamic it ll be shorter than video or bigger than video duration that’s why i am using amovie command for replace audio with looping to infinite, and add -shortest command at last.

  but it won’t be worked. it goes to infinite process.

  Here is my command

  [-y,
  
   -i, /storage/emulated/0/Received/VID-20190407-WA0001.mp4,
  
   -i, /storage/emulated/0/Received/MP4_20190220_114210.mp4,
  
   -strict, experimental,
  
   -filter_complex, [0:v]scale=iw*min(480/iw\,480/ih):ih*min(480/iw\,480/ih), pad=480:480:(480-iw*min(480/iw\,480/ih))/2:(480-ih*min(480/iw\,480/ih))/2,setsar=1:1[v0];
  
                    [1:v]scale=iw*min(480/iw\,480/ih):ih*min(480/iw\,480/ih), pad=480:480:(480-iw*min(480/iw\,480/ih))/2:(480-ih*min(480/iw\,480/ih))/2,setsar=1:1[v1];
  
                    [v0][v1] concat=n=2:v=1[vTemp];[vTemp]setpts=0.25*PTS[finalv];
  
                    amovie=/storage/emulated/0/VideoEditor/.caches/Video_editor_1560762451434.mp3:loop=0,asetpts=N/SR/TB[aaa],
  
    -map, [finalv], -map, [aaa],
  
   -shortest, -preset, ultrafast,
  
   /storage/emulated/0/Video_1560762463583.mp4]

  here is logs of the process (logs going to infinity, but i added till stackoverflow limit)

• ffmpeg avcodec_send_packet/avcodec_receive_frame memory leak

  23 janvier 2019, par G Hamlin

  I’m attempting to decode frames, but memory usage grows with every frame (more specifically, with every call to avcodec_send_packet) until finally the code crashes with a bad_alloc. Here’s the basic decode loop :

  int rfret = 0;
  
  while((rfret = av_read_frame(inctx.get(), &packet)) >= 0){
  
      if (packet.stream_index == vstrm_idx) {
  
  
  
          //std::cout << "Sending Packet" << std::endl;
  
          int ret = avcodec_send_packet(ctx.get(), &packet);
  
          if (ret < 0 || ret == AVERROR(EAGAIN) || ret == AVERROR_EOF) {
  
              std::cout << "avcodec_send_packet: " << ret << std::endl;
  
              break;
  
          }
  
  
  
          while (ret  >= 0) {
  
              //std::cout << "Receiving Frame" << std::endl;
  
              ret = avcodec_receive_frame(ctx.get(), fr);
  
              if (ret == AVERROR(EAGAIN) || ret == AVERROR_EOF) {
  
                  //std::cout << "avcodec_receive_frame: " << ret << std::endl;
  
                  av_frame_unref(fr);
  
                  // av_frame_free(&fr);
  
                  break;
  
              }
  
  
  
              std::cout << "frame: " << ctx->frame_number << std::endl;
  
  
  
              // eventually do something with the frame here...
  
  
  
              av_frame_unref(fr);
  
              // av_frame_free(&fr);
  
          }
  
      }
  
      else {
  
          //std::cout << "Not Video" << std::endl;
  
      }
  
      av_packet_unref(&packet);
  
  }

  Memory usage/leakage seems to scale with the resolution of the video I’m decoding. For example, for a 3840x2160 resolution video, the memory usage in windows task manager consistently jumps up by about 8mb (1 byte per pixel ??) for each received frame. Do I need to do something besides call av_frame_unref to release the memory ?

  Update 1 : (1/21/2019) Compiling on a different machine and running with different video files I am not seeing the memory usage growing without bound. I’ll try to narrow down where the difference lies (compiler ?, ffmpeg version ?, or video encoding ?)

  Update 2 : (1/21/2019) Ok, it looks like there is some interaction occurring between ffmpeg and Qt’s QCamera. In my application, I’m using Qt to manage the webcam, but decided to use ffmpeg libraries to handle decoding/encoding since Qt doesn’t have as comprehensive support for different codecs. If I have the camera turned on (through Qt), ffmpeg decoding memory consumption grows without bound. If the camera is off, ffmpeg behaves fine. I’ve tried this both with a physical camera (Logitech C920) and with a virtual camera using OBS-Virtualcam, with the same result. So far I’m baffled as to how the two systems are interacting...

• How to fix : Frame rate differs from source after encoding certain mp4 videos to wmv

  25 juin 2019, par hpenhp

  I’m having trouble with a usually working ffmpeg script for encoding mp4 and more to wmv. The goal is to keep it like the original, except for the resolution (smaller) and the format (wmv).

  When it usually works for a lot of videos, on some of them it doesn’t... and i would like to understand and avoid that.

  I tried several things, forcing the framerate for the output, using -vsync 2 option, -vsync 0 also.. noone of that fixed the issue.

  An other thing, worth adding, is that the fps value from media info is good (24 fps) on the output like the input, but through the M$ windows explorer, it says 30 frames per sec, and when you play the video you see that the text that was matching the input doesn’t match the output any more (because of the fps mismatching).

  Below the script i use :

  ffmpeg -threads auto -i input.mp4 -s 480*320 -b:v 1000k -vcodec msmpeg4 -acodec wmav2 -f asf output.wmv

  EDIT :
  My workaround was to encode to MPEG, doing this, i’m able to read my file and the frame rate is same as source. If someone knows why it couldn’t keep the original framerate in wmv, i’m still interested to know.
