I cannot run this command:
ffmpeg.exe -vf scale='min(250,iw)':-1 ...
When there are '
or "
in an argument, the solution is to wrap the argument with shellArgument
as it will properly format the parameter:
import 'package:process_run/shell.dart';
void main(List<String> arguments) async {
// Incorrect
await run("echo scale='min(250,iw)':-1");
// Correct
await run('echo ${shellArgument("scale='min(250,iw)':-1")}');
}
should give:
$ echo scale=min(250,iw):-1
scale=min(250,iw):-1
$ echo "scale='min(250,iw)':-1"
scale='min(250,iw)':-1
Thanks.
