Transcoding always fail with this particular video from snapchat (don't have another sample)? File is 418KB. I've tried on 4 different devices and the problem is the same. Using v0.8.0 Maybe linked to #15 ?
This is my config:

val mTranscodeVideoStrategy = DefaultVideoStrategy.Builder()
    .bitRate(3000000.toLong())
    .addResizer(AtMostResizer(720, 1280))
    //.addResizer(ExactResizer(Size(720, 1280)))
    .build()

Transcoder
    .into(compressedFilePath)
    .setValidator(WriteVideoValidator())
    .setVideoTrackStrategy(mTranscodeVideoStrategy)
    .addDataSource(content.contentURL!!)
    .setListener(this@CompressFileWorker).transcode()
    .get()

I've tried without .bitRate() and the result is the same. Somehow I'm using the validator the wrong way since the file is already compressed and below my threshold.
Here is the errorlog:

I think somehow it seems no tracks are set but tbh couldn't figure out the exact problem by myself. You can download the file here: https://drive.google.com/open?id=1Jcwu2ryTyEwv5eWgUzZGA_kdHJ_KUhjD

Any idea why it crashes?

v0.9.0 fixed the issue, so it was indeed linked to #14, thanks for the release!
