FFMPEG convert webm to mp4 not working

I have upgrade to the latest ffmpeg which supports webm, but I can't seem to convert webm to mp4

ffmpeg -i filea.webM -sameq filea.flv

I am getting this error

swScaler: Unknown format is not supported as input pixel format
Cannot get resampling context

I am not sure what to do.

You are asking to convert to mp4 but have added .flv output format in your command, try:

ffmpeg -i your_input_filename.webm -qscale 0 your_outfile_name.mp4

In newer ffmpeg versions, "-sameq" option has been removed, you have to use "-qscale" instead.

ffmpeg -i your_input_filename.webm -qscale 0 your_outfile_name.mp4

ffmpeg -i file.webm -strict -2 file.mp4

seems to be OK.

I use ffmpeg version 0.10.9-7:0.10.9-1~lucid1.
