• cronjob to play files in a folder with ffmpeg causes delay between songs. how to avoid ?

  21 juillet 2014, par Andy

  I have a cron set up to check for a specific stream and if its not playing(usually means that file is over) it will randomly select other file.

  The command :
  /root/bin/ffmpeg -re -i $(ls /usr/btv/btvconcerts/*.mp4 | shuf -n 1) -vcodec copy -preset superfast -acodec copy -ar 44100 -ab 32k -f flv OUTPUT

  The problem I have is that the cron is running every 1 minute and so there could be a delay between the streaming files for up to 1 min + the time it launches etc

  Is there a command i could use just to constantly loop through the files without crontab ?

• drawbox don't work on remote server and works on local

  5 décembre 2015, par efpies

  I’ve got a completely weird problem.

  I need to draw the text over the filled rectangle. The problem is that the command line command that work on my local machine don’t work on the server ! To be precise, only drawbox command don’t work.

  Here’s the command.

  ffmpeg -i shake.mp4 -vf "scale=300:150,setsar=1/1,drawbox=w=300: h=16: x=0: y=134: color=0x1a5757: t=1000000,drawtext=x=5: y=136: fontfile=Arial.ttf: text='fdsf': fontcolor=0xd44e4e"  -c:v h264 -preset medium -b:v 256k  -f mp4 shake_conv.mp4

  Clarification

  It seems, that my question is unclear. Ok, here’s clarification.

  I need to draw the text over the filled rectangle.

  It means, that, at first, I have a video. Then I would like to draw a bar at the [0 ; 134] with width 300px and height 16px, painted with #1A5757 color. And over that bar should be placed a text.

  The problem is that the command line command that work on my local machine don’t work on the server !

  It means that I have 2 environments : local machine (my Mac OS X 10.9.2 with ffmpeg 2.0.2 installed) and the server (Debian 7 with ffmpeg 1.0.8 installed. Quite old, dunno, but no errors were in this case ; can’t find any info about version dependency).

  The last part,

  the command line command that work on my local machine don’t work on the server

  To be precise, only drawbox command don’t work.

  means that the same command above draws the bar I need in my local environment but don’t draw it on the server side. The text is drawed correctly in both cases. One more time : the text is drawed, the bar isn’t drawed. That’s my problem. I need a bar over the video. And there aren’t any bars when I execute this command on server.

  Now, I hope, this is quite clear.

  Here’s the output.

• System command error code of 126

  15 octobre 2012, par mike O.

  Please, I am trying to convert an mpg file to flv with ffmpeg. I am using the php system() command to execute it. However, I get an error code of 126. Any idea of what that means ? Here is my code :
  system($ffmpegPath. " -i ". $srcFile. " -b 4000k -maxrate 4000k -bufsize 1835k ". $destFile, $cmd_status)

  Thanks. I discovered I was referring to the wrong ffmpeg binary. However, now that I am pointing to the right binary, I get an error of 127. Any help ?
