[FFmpeg-user] Ffmpeg webm problem

[red red]

Good morning i have a problem that i would like to have answer on.

Please confirm if there is a possibility:



   -

   to conver from webm format to flv or any other format
   -

   to create a image (thumbnail) from webm format


 I couldn't find any anser on the web that there is this possibility.
Converting to webm format is

possible but from it only creates errors.


 This error occurs when trying to create a jpeg from webm movie:

Unknown format is not supported as input pixel format.


 Please take seriously this email ant I thank i advance for any help.
