Setting trim start

[nicksam112]

So poking around the code it seems as though it's only possible to trim starting from the very start of the video and setting an end point via duration.

Is there going to be any support for setting a starting trim time, or have I missed it somewhere? Thank you!

When it gets cold here and I'm not buried in my day job I'll add this feature if it hasn't already been. It would be nice to have.

Thanks.

So looking into it, ffmpeg android supports a start time so it should be almost trivial. I'll try to submit a PR this weekend.

I achieved this by doing:

VideoEditor.java
line 192

final String videoStartTime = options.getString("startTime");
final String videoEndTime = options.getString("endTime");

line 224

Clip clip2 = new Clip();
clip2.path = new File(inFile2.getAbsolutePath()).getCanonicalPath();
clip2.startTime = videoStartTime;
clip2.endTime = videoEndTime;
ffmpegController.getInfo(clip2);
listVideos.add(clip2);

FfmpegController.java
line 226

public static final String STARTTIME = "-ss";
public static final String DURATION = "-t";

line 658

public Clip convertToMP4Stream (Clip mediaIn, String startTime, String endTime, String outPath, ShellCallback sc) throws Exception
{

line 671

if (startTime != null) {
    cmd.add(Argument.STARTTIME);
    cmd.add(startTime);
}

if (endTime != null) {
    cmd.add(Argument.DURATION);
    cmd.add(endTime);
}

line 1182

mdOut = convertToMP4Stream(vdesc,vdesc.startTime,vdesc.endTime,fileOut.getCanonicalPath(), sc);

You can now trim a video in the latest version (0.0.6) of the plugin -

@rossmartin Thanks for all your hard work on this plugin.

Just a note, I had issues with the duration logic (FfmpegController.java line 672)

if (duration != -1)
    {
        cmd.add(Argument.DURATION);
        double dValue = mediaIn.duration;
        int hours = (int)(dValue/3600f);
        dValue -= (hours*3600);
        cmd.add("0");
        cmd.add(String.format(Locale.US,"%s",hours));
        cmd.add(":");
        int min = (int)(dValue/60f);
        dValue -= (min*60);
        cmd.add("0");
        cmd.add(String.format(Locale.US,"%s",min));
        cmd.add(":");
        cmd.add(String.format(Locale.US,"%f",dValue));
        //cmd.add("00:00:" + String.format(Locale.US,"%f",mediaIn.duration));
    }

It would output invalid commands for ffmpeg and create errors. I replaced it with:

if (startTime != null) {
    cmd.add(Argument.STARTTIME);
    cmd.add(startTime);
}

if (endTime != null) {
    cmd.add(Argument.DURATION);
    cmd.add(endTime);
}

And then javascript has to pass through the exact start time and end time strings (rather than integer durations):

startTime = '00:00:05.2'
endTime = '00:00:08.1'
