[Feature Request] Trim time

[aweck]

Is there a good way to trim the time of a video while transcoding? Similar to this: ypresto/android-transcoder#14

It's not supported at the moment, sorry! If you want to implement on your own, I would use a custom DataSource subclass.

@natario1 Thanks! Would you be open to a pull request adding this feature? It's required for my use case, but I'd prefer if I could check it in here as having a custom lib would make maintenance and updates more painful.

Sure! I can give you advices if you need.

The key part that is important to me, is that we should implement this as an isolated component, like a TrimDataSource class, without touching the other components in the pipeline.

This way the usage would be:

// Wrap source
DataSource source = ...;
DataSource wrapper = new TrimDataSource(source, trimStart, trimEnd);

// Then pass to transcoder as a regular source
Transcoder.into(file)
    .addSource(wrapper)
    .transcode()

And you could trim separately each segment in case of concatenation.
