I'm saving mythtv streams to my pogoplug. Ideally it would be able to handle 4 simultaneous streams being saved to the disk as well as a single file read back out.

I'm seeing high load of up to about 80% cpu utilized by ffmpeg during the save of a single file. Anyone know why ffmpeg is involved in the save of the mpeg file?

hi there, the pogoplug uses ffmpeg to extract a thumbnail from your video stream for display in the web application.

hmm, so it seems I'm putting myself in a hole here then. Mythtv, or HDHomerun streams the TVShow onto the pogoplug live, so over the course of an hour the show will continually stream. Does that then mean that during the whole show ffmpeg will be trying to build a single thumbnail and sucking up 80% of the CPU?

Is there a way to make it only build the thumbnail on a file that isn't growing? Like say stat the file and only when the size is constant build a thumbnail? Or alternatively if that isn't an option can I disable thumbnail generation and just do it once a day via cron or something?
