* Edits a video file, saving the contents to a new file. This involves decoding and
* re-encoding, not to mention conversions between YUV and RGB, and so may be lossy.
* <p>
* If we recognize the decoded format we can do this in Java code using the ByteBuffer[]
* output, but it's not practical to support all OEM formats. By using a SurfaceTexture
* for output and a Surface for input, we can avoid issues with obscure formats and can
* use a fragment shader to do transformations.
