Please paste the full output of the FFMPEG test output area from the bottom of the FFMPEG Settings tab of the plugin settings page. Make sure you put the code between backticks so it’s formatted properly.
If there aren’t any errors in the test output, post a link to a video you’re having a problem with. Does it happen with every video? Have you ever been able to encode videos and did something change?
Hi, thanks for the quick response. It happens to all videos but only since we changed server. FFMPEG is installed. Am I missing something?

Codec AVOption rc_lookahead (Number of frames to look ahead for alternate reference frame selection) specified for output file #0 (/home/dingvideo/public_html/wp-content/uploads/sample-video-h264-480.mp4) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.

You have a new version of FFMPEG so you should disable the legacy FFMPEG options in the FFFMPEG settings tab.
