Both example 1 and example 2 show how to use ExtraArgs. Perhaps show me what you tried, and what it outputted.

We don't have a -filter:v flag support right now. We do have [setComplexVideoFilter()](https://bramp.github.io/ffmpeg-cli-wrapper/net/bramp/ffmpeg/builder/FFmpegOutputBuilder.html#setComplexVideoFilter-java.lang.String-), which would most likely do what you want. However, you could also use `addExtraArgs("-filter:v", "pad=width=:height=:x=:y=")`.

The `setInput(in).setFormat("mp3")` line is forcing the input to be read as MP3. Move the setFormat after the addOutput. Also you must likely don't need the setAudioCodec("aac") line, that would be...

`-payload_type 8` is encoded as a single argument. Split that into two, and it should work: ``` addExtraArgs("-payload_type").addExtraArgs("8") ```

What have you tried? and how would you do it with just the pure ffmpeg command?

Ok, I see two errors: ``` [concat @ 000000000030a4e0] Impossible to open 'lqCfwIbG1EU.mp4' d:\11111\list.txt: No such file or directory ``` I'm assuming its opening list.txt, and then failing to find...

I'm sorry I can only help in English

This library just wraps the command line tool. So if you construct similar command line flags as [shown here](https://trac.ffmpeg.org/wiki/ExtractSubtitles), you should be able to extract the subtitles to say a...

This seems a little spammy. Has this project been reviewed by hound? Perhaps the badge should link to that review.

For this, I need to refactor the project to support a FFmpegInputBuilder, so we can attach arguments to particular input streams. Right now, arguments are only attached to output streams.
