[FFmpeg-user] Unable to transcode yuv420p file

[Atish Kathpal]

Hello

I am unable to transcode any yuv420p file using ffmpeg. I am also unable to
extract any information about the file using ffmpeg -i <file> command. VLC
is showing random color lines on playing the yuv file. Any pointers on how
I could make this work?

ffmpeg -i T2V0041102_Big_Ben_160x600p.yuv -vcodec mpeg4 out.mp4
