• Can not copy RTSP streamed video in android using FFMPEG [on hold]

  28 mars 2017, par user711457

  I am developing an android application. In my application I wanted to record live streamed video using ffmpeg library. I write one code for record live streamed video but it does’t work. It shows some error. If any one know this please help me.

  This is the code I am used to record video

  try {
  
  
  
          fFmpeg.execute(new String[]{"ffmpeg -i rtsp://192.168.1.1:6667/streamhd -acodec copy -vcode c copy"+String.valueOf(getCacheDir())+"/MyVideo.mp4"}, new ExecuteBinaryResponseHandler() {
  
  
  
              @Override
  
              public void onSuccess(String message) {
  
                  Log.d("fffffff", "FFmpeg cmd success");
  
              }
  
  
  
              @Override
  
              public void onFailure(String message) {
  
                  Log.d("ffffffffffff", message.toString());
  
              }
  
          });
  
      }catch (FFmpegCommandAlreadyRunningException e) {
  
          // Handle if FFmpeg is already running
  
          e.printStackTrace();
  
          Log.w(null,e.toString());}

  when I execute this block I get the following error message.

• Images to video in PHP ? [duplicate]

  24 juin 2013, par jesper

  This question already has an answer here :

  • How to create videos from images with php ?
    

    3 answers

  I have tried to make a images to video converter, and this works.

  ffmpeg  -i /home/psafari/public_html/common/images/icon3.png -vcodec mpeg4 /home/psafari/public_html/" . time().".avi

  But how can i set the duration of the movie ? So it's maybe 7 minutes long ?

  Another question :

  I have 2 pictures, now the command only make the video from image "icon3.png", but i need it to run maybe picture2.png the first 5 seconds, and the rest (6.55 seconds) it has to view icon3.png ex.

• FFMPEG x264 (fourcc=0x21) codec is not working with OpenCV

  6 mars 2020, par dkac

  I’m trying to use mp4 format coding (fourcc=0x21) on OpenCV 3.2 without success. Probably I have a problem with my Ubuntu 18.04 setup but currently I’m running out of ideas how to fix it. First, I recompiled FFMPEG with x264 support. Than, recompiled OpenCV (with contrib and OPENCV_ENABLE_NONFREE=ON, WITH_FFMPEG=ON). It is still not working.

  I cannot use fourcc different than 0x21. I mean.. I cannot use another codec.

  Example :

  >>> import cv2
  
  >>> out = cv2.VideoWriter('output.mp4', 0x21, 20.0, (640,480))
  
  OpenCV: FFMPEG: tag 0x00000021/'!???' is not found (format 'mp4 / (null)')'

  However, this is working fine (other fourcc, codec) :

  >>> out = cv2.VideoWriter('output.mp4',0x31637661 , 20.0, (640,480))

  OpenCV compiled with FFMPEG support (version 3.2), cmake config :

  Video I/O:
