That's just an example, the same mistake with the number of HD videos I uploaded yesterday.
Let's continue with the same video: decoding was successfully finished for Ogg 160p, 360p, 480p only, all other decoding finished with errors. When I press "Play" for video, I have no sound (and only Ogg 160-480p), but when I press "Source file" I see HD file with sound and everything. Something seems to be broken in the internal decoder...
It's not a very large file. One of them I clicked on just showed an error of "timeout"
The error in comment 0 is due to libav being too old (doesnt support opus). Whenever we update ubuntu on the transcode job servers this will be fixed. (Soon i really hope)
