It can extract RAR archive files as far as I know, but I've tried with files I know are mp4 as well. The errors you're seeing are subpack files without video in them, only subtitle files, I think... either way I've enabled debugging and repeated the process. Sorry!

This time I've tried downloading and streaming both types of files, the last two (community s05e10 (packed in a RAR file) and breaking bad s01e01 (straight mp4)) I did from the SAME machine that the server is running on, and they completed successfully. I don't know if this can tell you anything useful..

Thanks again for your help.
