Longer answer: screenshot and merge methods are just helper "recipes" to help achieve common actions as such they have a limited scope and limited possible options. Do it manually with custom options/filters. How can I add filters/options when taking screenshots or using mergeToFile? One of those should be called and give you more information about what happened.
Please ensure that you added handlers for both the end and error handlers. Beware though this is not the most appropriate place to talk about ffmpeg usage (try their mailing list or irc channels instead). If you can't find how to do what you want, feel free to create an issue. If you find some command line switch that has no matching fluent-ffmpeg method, you can use the inputOptions() and outputOptions() method instead. When you know how to achieve your goal on command line and don't know how to translate it to fluent-ffmpeg calls, please ensure that you've read the documentation first. If you don't, have a look at the ffmpeg documentation and ask the ffmpeg community first, as you're far more likely to get an appropriate answer there. Please ensure first that you know how to achieve what you want on command line.
