[FFmpeg-user] getting error while encoding yuv raw video

[Hardik Sharma]

Hi guys,

I am getting error while doing encoding of yuv video to h264 format. Please suggest any changes for the following command but I was using the same command previously and it was working fine. I updated ffmpeg recently I am not sure if that affected it. Command and error is as following-
