• ffmpeg RTSP MPEG4 to h.264 RTSP not streaming

  25 août 2017, par martyn

  I’m trying to re stream a RTSP feed and convert to h264.

  I’m using the following command line :

  C:\Users\Martyn>ffmpeg -re -i rtsp://192.168.2.207/VideoInput/1/mpeg4/ -preset ultrafast -vcodec libx264 -tune zerolatency -b:v 900k -f rtsp udp://192.168.0.2:1234

  The output I get is :

  C:\Users\Martyn>ffmpeg -re -i rtsp://192.168.2.207/VideoInput/1/mpeg4/ -preset u
  
  ltrafast -vcodec libx264 -tune zerolatency -b:v 900k -f rtsp udp://192.168.0.2:1

• Convert mp3 -> Video with static image ( ffmpeg/libav & BASH )

  19 août 2014, par Max

  Some years ago I used the following bash script to get a video out of mp3’s and one image (so the image in the video was freezed over the length of the mp3), which worked out fine.

  i=0;
  
  for file in *.mp3; 
  
  do 
  
  i=$((i+1));
  
  ffmpeg -loop 1 -shortest -y -i image.jpg -i $file -acodec copy -vcodec libx264 $file.flv;
  
  done

  Now I wanted to use this again for doing the same.

  Problem :

  It does not stop converting at the end of the mp3. Means the current mp3 file eg. has a length of 3 minutes and the script converts until forever or I stop it, so the length of the flv is much bigger than 3 minutes.

  (ffmpeg is installed, but with libav the same happens)

• Convert images into video

  24 septembre 2017, par Disha Shukla

  I have some images in the folder. I want to convert all images into videos. But the problem is that when the resolution is different it shows the error. I don’t want to stretch the images in the video. I just want to keep image size as it is. But it shows this error.

  My Command :

  ffmpeg -framerate 1/3 -pattern_type glob -i "images/*.jpg" -i trinity.MP3 -shortest -c:v libx264 -r 30 -vf "scale=iw*sar:ih , pad=max(iw\,ih*(16/9)):ow/(16/9):(ow-iw)/2:(oh-ih)/2" -aspect 16:9 -pix_fmt yuv420p out.mp4 -y

  Is there any way to keep resolution as it is and make a video of all images ?
