FFMPEG consumer audio n video output is fast-forward (normal than 1x speed)


We are using Caspar v2.3.0 and hitting a weird issue where sometimes when we play back the output of ffmpeg consumer, it plays back in a fast-forward mode. Both audio and video are affected in this. Sometimes output video is getting played faster than 1x speed. Attaching the video file for reference (trimmed the video from the original video).

Whenever this happens video and audio is remain in Fast-Forward for sometime.

I’m not sure how to address this problem and was wondering if anybody could help me approach this. Anyhelp would be appreciated.

We also recorded output of ffmpeg consumer which has same behaviour. Here is the metadata information :
