Data stream encoding not supported yet (only streamcopy)

I'm having an issue with some videos from my plugin not playing.

This is the plugin I'm using, http://forum.serviio.org/viewtopic.php?f=20&t=11457, configured as a web resource with this URL, http://science.discovery.com/tv-shows/how-its-made.
Any of the newest 20 videos or so contain those data streams and give this error.

Here is the ffmpeg output for the video.

  Code:

Here is what I see in the log. I tried this, http://forum.serviio.org/viewtopic.php?f=5&t=7, to get the ffmpeg cmmand, but I still don't see it in the log.

  Code:

It seems like maybe ffmpeg is failing while trying to transcode the data streams?
