speed about video_stream_opencv HOT 5 CLOSED

I understand you are publishing from a video file.

Use the latest version of the package from the master branch and change your set_camera_fps parameter in the launchfile to be the fps you want.

The default set_camera_fps is 30. And the previous released version had no control on how fast you read from a video file, that was added last week (will re-release soon).

(If you don't want to lose any frames, if you don't mind, change your fps parameter and it will drop frames to publish at the rate you want).

I find another problem, if I modify the "camera_name", this set will not work

@sunrentao That was a real mistake, I just pushed the changes to fix it. Let me know if it works for you (I just tried it myself and it worked).
