Controlling ffmpeg at runtime with zmq
3 avril 2023, par GavinI want to dynamically change the rectilinear view (eg its yaw) of a 360 video as it plays.


basic command


To take a 360 video and show a flat/normal view at a yaw perspective of 60 degrees


ffmpeg -i input360.mp4 -vf "v360=input=e:rectilinear:yaw=60,scale=iw/4:-1" out60.mp4

This works fine.

Changing the yaw during playback


I understand ffmpeg has two methods to change filter params at runtime ; sendcmd (file based) and zmq (message based)


I got sendcmd method working, but am struggling to understand zmq syntax and use. ffmpeg's zmq docs are pretty sparse.
I am using a local Windows 10 PC


sendcmd


ffplay -i input360.mp4 -vf "sendcmd=f=cmd.txt,v360=input=e:rectilinear:reset_rot=1,scale=iw/4:-1"


with a cmd.txt file


0-5 [expr] v360 yaw 'lerp(0,90,TI)';
5-10 [expr] v360 yaw 'lerp(90,0,TI)';



result : yaw changes from 0 to 90 degrees from t=0-5s and then 90 to 0 degrees from t=5-10s. Perfect


zmq


ffplay -i input360.mp4 -vf "v360=input=e:rectilinear:reset_rot=1,zmq,scale=iw/4:-1"


I got zmqsend from ffmpeg-tools.zip and added to my ffmpeg bin directory


- 

-
execute above ffplay command from terminal window #1 - and see video playing


-
Open terminal window #2 and execute : echo v360 yaw 90 > zmqsend








result : no change to video yaw. No errors either


What am I doing wrong ? Im not sure if my ffmpeg command is wrong, or if my zmq message does not reach ffmpeg (or both). I checked my ffmpeg v2022-10-10 config has —enable-libzmq
