• What codec do I need to convert .wav to .mp3 with ffmpeg ?

  19 septembre 2011, par LedZeppelin

  I am able to convert from .mp3 files to .wav files.

  I've already tried installing unstripped-51 per a suggestion from a previous question but I am still unable to convert from .wav to .mp3

• Why does FFMPEG reports the wrong duration ?

  20 octobre 2011, par Adrian Lynch

  I have an oldish build of FFMPEG that I can't easily change.

  We use FFMPEG to find the duration of video and sound files. So far it has been working wonderfully.

  Recently on an uploaded file, FFMPEG has reported a 30 second file as being 5 minutes 30 seconds in length.

  Could it be something wrong with the file rather than FFMPEG ?

  If I use FFMPEG to convert to another file, the duration is restored.

  In case it matters, ffmpeg -i 'path to the file' produces :

      Must supply at least one output file
  

  It's that very command I use to then extract the duration with RegEx.

  Does anyone have a nice application that can do what I'm trying above but get it right 100% of the time ?

• 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.
