Hey folks!

Netflix has published a sample IMF package with lots of neat gee-whiz
features like lossless 10 bit 4kp60 J2K video graded for HDR!

The video actually seems to pass through ffmpeg just fine - I was able to
step it down into 1080p ProRes no problem. However, the audio files don't
seem to be compatible with ffmpeg just yet.

mxf @ 0000000000d369a0] OPAtom misinterpreted as OP1a? KLV for edit unit 0
extending into next edit unit is not implemented. Update your FFmpeg
version to the newest one from Git. If the problem still occurs, it means
that your file has a feature which has not been implemented.
[mxf @ 0000000000d369a0] If you want to help, upload a sample of this file
to ftp://upload.ffmpeg.org/incoming/ and contact the ffmpeg-devel mailing
list. (ffmpeg-devel at ffmpeg.org)
Guessed Channel Layout for Input Stream #0.0 : stereo

I'm on the latest zeranoe build from today.

Here's the IMF package:
