I know that HTML5 and also Flash provide a method to show the user a preview thumbnail image of a video prior to the user pressing the Play button. This is done by referencing an external image file that is distinct from the video itself.
But I want to know if there's a technique for encoding a video in FFMpeg so that the thumbnail image is embedded into the video from the start. Audio files embed a thumbnail image, so why can't video? I have read a suggestion somewhere that as part of encoding a video, you can insert a thumbnail image into the first frame of a video and this will cause that thumbnail image to appear automatically.
Can anyone explain to me whether this is possible, and if so, how would I issue a command to FFMpeg in order to achieve it?
