Golang : ffmpeg with os/exec.Command() returns non-zero status
Problem:
You want to use ffmpeg
with os/exec.Command() and Run() to create your video files.
However, it keeps bombing out with the error message:
exit status 1
You are able to execute the command with the supplied parameters and flags just fine on your terminal.
What's going on? How to fix this?
Solution:
Golang's os/exec.Command()
function does not have the shell=true
feature like Python did. ffmpeg is very sensitive to white spaces when running from another program. To fix the problem, simply remove whitespaces by using ,
instead of +
to assemble the flags and parameters to ffmpeg.
For example,
cmd := exec.Command("ffmpeg", "-r "+recordedFPSstring+" -i "+videoFileName+" -r 6 temp_"+videoFileName)
to
cmd := exec.Command("ffmpeg", "-r", recordedFPSstring, "-i", videoFileName, "-r", "6", "temp_"+videoFileName)
