[FFmpeg-user] rtp source stopped working upgrading ffmpeg from 3.0.0 to 3.1.1

Thu Jul 7 03:20:16 CEST 2016

Hi,

I'm hoping someone can shed light on an issue I'm experiencing after
upgrading ffmpeg from 3.0.0 to 3.1.1:  Reading source input from rtp no
longer works. tcp dump shows the data stream arriving (no changes other than
upgrading ffmpeg), but ffmpeg is treating the input as if it's null. I've
reproduced the same issue (post-ffmpeg upgrade) on two servers - identical
symptoms.

Checking release notes for v3.1.0, there's mention of: "protocol
blacklisting API". Looking through the diff for that change, looks like an
extension of the newer parameter -protocol_whitelist added in v3.0. Which,
for me, required the addition of -protocol_whitelist file,udp,rtp in order
to read the same rtp source stream that was working in ffmpeg v2.8.
Perhaps, the shell parameter isn't being passed internally? Is there a new
secondary parameter I need to explicitly pass to this new api?

Any thoughts?
Thanks in advance!

Relevant output follows..
