Can you please let me know what might be the issue?

Hi Karthik,

From the log you sent, it's attempting to run

ffmpeg, -nostdin, -nostats, -ss, 282.94600, -i, /data/opencast/workspace/mediapackage/4f492334-446b-4271-8975-cc35e758b905/9c1692cf-7412-4bec-a758-66adaeb057c4/extremevaluetheorem_example1-a2a8cc59-4a38-432b-8ec4-64b77f1aebdc.mp4, -r, 1, -frames:v, 1, -filter:v, yadif,scale=320:-1, /data/opencast/workspace/mediapackage/4f492334-446b-4271-8975-cc35e758b905/9c1692cf-7412-4bec-a758-66adaeb057c4/extremevaluetheorem_example1-a2a8cc59-4a38-432b-8ec4-64b77f1aebdc_e685066f-32f5-421e-bc64-c228c6e120a5-preview.jpg

but...

Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)

resulting in 

Extracted image /data/opencast/workspace/mediapackage/4f492334-446b-4271-8975-cc35e758b905/9c1692cf-7412-4bec-a758-66adaeb057c4/extremevaluetheorem_example1-a2a8cc59-4a38-432b-8ec4-64b77f1aebdc_e685066f-32f5-421e-bc64-c228c6e120a5-preview.jpg is empty!

So Opencast is running an operation, which incorrectly generates an empty file, then attempts to do things with said file and fails.  If I had to guess, I would say you've either modified your encoding settings and have an issue, or the version of ffmpeg installed on your worker(s) does not match what Opencast is expecting.
