poster = vide.path;
if (typeof vide.path === 'object') {
  if (vide.path.poster) {
    poster = vide.path.poster;

//------------////////////////////////////////////////////////////////// var extpos = poster.lastIndexOf('.'); if (extpos > 0){ var ext = poster.substring(extpos+1); if ((ext === 'jpeg')||(ext === 'jpg')||(ext === 'png')||(ext === 'gif')){ vide.settings.posterType = ext; } } //------------///////////////////////////////////////////////////////// } else { if (vide.path.mp4) { poster = vide.path.mp4; } else if (vide.path.webm) { poster = vide.path.webm; } else if (vide.path.ogv) { poster = vide.path.ogv; } } }
