title: How to limit output filesize of ffmpeg input stream to 10 megabytes
body: <p>I am subscribing to an input stream from tvheadend using ffmpeg and I am writing that stream to disk continuously . I'd like to limit this output stream so that there are 10 megabytes of data stored at maximum at any time. </p>
  
  <p>I already looked into sponge from moreutils and the linux buffer command to build some kind of a pipe . Though, I could not find a working solution yet. Who can point me into the right direction?</p>
