[FFmpeg-user] ffmpeg not working on server

[Waleed Afridi]

*Message By Hosting Suport Team.....*

We've uploaded the file '20051210-w50s.flv' to your images/videos folder,
and run the following command from shell directly:

/usr/bin/ffmpeg -i 20051210-w50s.flv -vcodec libx264 -ar 22050 -crf 28
20051210-w50s.mp4 -r 1 -y -vcodec mjpeg -f mjpeg 20051210-w50s.jpg

The following FFMPEG output results:

[flv @ 0x18b6670]Estimating duration from bitrate, this may be inaccurate

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