  10 janvier 2018, par Yanshof

  I also have audio file (.wav) that contain 1 minute of sound.

  I need to add the audio to the exist video but the audio need to start at after one minute of the video

  How to do it ?

  ( prefer using ffmpeg if its possible )

  try already this query ( 30 seconds deley )

• FFmpeg smearing rtp missed packet

  3 janvier 2018, par Akim Benchiha

  I’m using ffmpeg to combine streams. But during the combinaison I have some errors/Warnings. I don’t know why. I can see the frames are dropping. And the output video is poor quality

  Here the situation :
  First : Try to combine local video and a rtsp stream from data center.

  ffmpeg -i rtsp://cloudzensg.loginto.me:554/livecast -i Xmen2trailer.mov -filter_complex "[0]scale=-1:-1[b];[1]scale=128:128[w];[b][w] overlay=10:10" -vcodec libx264 -preset ultrafast -f flv out.mp4

• Creating a video using ffmpeg in a PHP script

  30 décembre 2017, par Femzy

  I have been trying to solve this problem for a while now, but i have not got it through please someone should help me..
  My main objective is to collect user’n inputs and convert it to a video with black background, then the input text will be moving from left to right while the video is playing with audio in the background. Currently i was suggested to use "drawtext" but i have not find it working
  This is the code I use just to test the drawtext but the thing is, if i try it 10 times it will create a video file ones in many times i tried and even the video file would have 0 kb in size
  The Below code is my code

  The Below is the Report i got from the not working ffmpeg cmmand

  echo shell_exec('ffmpeg -f lavfi -i testsrc=duration=5:size=800x600:rate=30 -vf drawtext="fontfile=/usr/share/fonts/truetype/dejavu/DejaVuSerif-Bold.ttf:textfile=text.txt: x=(w-tw)/2: y=h-(2*lh): fontcolor=white: box=1: boxcolor=0x00000000@1" -preset ultrafast outex.mp4');
