[FFmpeg-user] Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height

[Walid Salman]

Hello,

Any one kindly to help me ...I need to change vido files to .mp4 and I am
using this comand and I get the error as you can see :

root at ltf4633 [~]# ffmpeg -i
