FFmpegBuilder params order cause error

[uzengo]

Describe the bug FFmpegBuilder some params order must add in -i option back

To Reproduce

        File file = new File("cut1.png");
        file.createNewFile();

        FFmpegBuilder builder = new FFmpegBuilder()
                .overrideOutputFiles(true)
                .addOutput(file.getAbsolutePath()).done()
                .addInput(probeResult).addExtraArgs("-vframes", "1");
        FFmpegExecutor executor = new FFmpegExecutor(ffmpeg);

        executor.createJob(builder).run();

Expected behavior ffmpeg -y -v error -vframes 1 -i /Users/xx/ffmpeg/cut.mp4 /Users/xxx/ffmpeg/cut1.png Option vframes (set the number of video frames to output) cannot be applied to input url /Users/xxxx/ffmpeg/cut.mp4 -- you are trying to apply an input option to an output file or vice versa. Move this option before the file it belongs to. Error parsing options for input file /Users/xxx/ffmpeg/cut.mp4. Error opening input files: Invalid argument

right command order

ffmpeg -y -v error -i /Users/xx/ffmpeg/cut.mp4 -vframes 1 /Users/xxx/ffmpeg/cut1.png

Version (if applicable):

• OS: [e.g. Linux]
• Java Version [e.g. 8]

Additional context Add any other context about the problem here.

@dirklu @bramp Hi, If requirement is just need to add vframe then don't use add extra arg method. Below code produce the required command.

File file = new File("/home/hariom/Downloads/download.jpeg"); file.createNewFile(); FFprobe ffprobe = new FFprobe(); FFmpegProbeResult probeResult = ffprobe.probe("/home/hariom/Downloads/video.mp4"); FFmpegBuilder builder = new FFmpegBuilder() .overrideOutputFiles(true) .addOutput(file.getAbsolutePath()) .setFrames(1) .done() .addInput(probeResult);

actual : ffmpeg -y -v error -i /home/hariom/Downloads/video.mp4 -vframes 1 /home/hariom/Downloads/download.jpeg expected :ffmpeg -y -v error -i /home/hariom/Downloads/video.mp4 -vframes 1 /home/hariom/Downloads/download.jpeg
