Detecting Type of Video Stream

I have 2 video streams

(1) VLC Generated Compressed MP4 UDP stream

(2) DV Uncompressed UDP Stream

Both are destined to a host. At this Unix receiving host, I would like to de开发者_高级运维tect type of stream coming using Bash or Python Scripting (without tcpdump, I do not have root priv.)

ANY idea guys how to implement ?

Thank you.

what about trying pyffmpeg out. you should be able to get the container info from that.
