[FFmpeg-user] set timestamps to system clock for rtmp streams (and issue with decklink video_pts new option)

hello,

*Issue:*

I need to synchronize several live rtmp streams on different pcs; the 
pcs are synchronized by ntp.

Instead of starting with 0, I'd like the timestamps to start with the 
system time.

This can be done with flash media live encoder, but ffmpeg is required 
for this project.

I use decklink capture cards (studio 4K).

=============================================

I am using the latest static build on windows by zeranoe

*what I tried:*

I tried several parameters on the output:

(1) -timestamp now -f flv rtmp://IP

(2) Also on the input:

e.g

ffmpeg -use_wallclock_as_timestamps 1 -f input device

which fails also (errors in red bold below); the timestamps still start

(3) I am using a decklink capture card so I tried the brand new option 
-video_pts wallclock and -audio_pts wallclock

The timestamps still start with zero. No error thrown.
