ffmpeg

[sn4fu]

Hi I have a stack (MacOS X 10.9) that sends shell commands to the terminal app. However I need to send a ffmpeg concat shell from the stack and nothing happens. no errors.
Other shells have worked for me but anything to do with ffmpeg seems to fail.
I have pasted this script directly into the terminal and it works fine. I'm a bit lost on this as the ffmpeg route is perfect for my ends.

this is the shell script. .

<ffmpeg -i "concat:/Volumes/terra/images/movie1.mpg|/Volumes/terra/movie2.mpg|/Volumes/terra/movie3.mpg" -c copy /Volumes/terra/xxx.mpg>

Hope there is a way round this . . .


I am using livecode community 7.04

Try something like

Code: Select all

on mouseUp pMouseBtnNo
   local cmd = "/usr/local/bin/ffmpeg"
   local tInput = "-i concat:/Volumes/terra/images/movie1.mpg|/Volumes/terra/movie2.mpg|/Volumes/terra/movie3.mpg"
   local tOutput = "-c copy /Volumes/terra/xxx.mpg"
   local tResponse
   
   put shell(cmd && tInput && tOutput) into tResponse
   put tResponse
end mouseUp

Thanks for the answer mwieder, but this gave a few permission errors and did not recognise output . . .

however I did add the path to ffmpeg and hey presto it works.

Did not understand why I needed to include the path from LC app when runs fine in terminal without path?

The "problem" is with the path in the type of shell that's being launched and the config files that come into play.

There are a few ways to deal with this. One is to state the path explicitly, another is to set the shellcmd before invoking shell, a third would be to fiddle with various config files. There aren't any solutions that are best, just depends on how you want to deal with things.

But yeah, it's a pain and it would be so much nicer if osx just behaved like linux.
