Multimedia content covers the Web, and we should provide access to all people. For this reason, we must consider including accessibility requirements in a synchronized manner with the alternative resources such as caption and audio description among others. In addition, it is very important to take into account accessibility requirements in the player to avoid barriers and to ensure access to this multimedia content as well as their resources. This paper presents an overall study on standards and players with accessibility requirements. Moreover, solutions to improve the accessibility features in the YouTube player are presented. Based on this study, we have distinguished a set of guidelines to take into account for including accessibility requirements in players. Furthermore, we suggest an agile evaluation process which indicates the order of accessibility guidelines to check. Finally, the proposed evaluation method is put into practice with a case study: accessibility features are evaluated in three widely used players.
