Nowadays computer systems are playing a vital role in almost every aspect of human life with the help of complex and user-friendly software systems. Multimedia players are one of the application of computers system used to watch videos and listen audios. In this paper, we conduct a comparative analysis of four media players i.e. VLC, QQ player, Windows media player class and Pot Player. We conduct a survey from exerts of different organizations on usability of media players, containing parameters i.e. learnability, efficiency, memorability, error, satisfaction. According the mention parameters we compare the given media players with each other.

Literature Review
Usability is an important quality attribute to be considered during software architecture design. Many usability benefits link directly to a variety of architectural tactics in addition to separation of the user interface and these benefits can be discovered early in the life cycle [1]. There are several techniques to evaluate software usability, these evaluations being quantitative and qualitative. The main way to quantitatively evaluate a software product is by using software usability metrics [2]. The success of any software or product depends on many factors and the usability is one of the most important factors. Usability is considered as the quality of software [3]. for assuring and improving quality, it is necessary to ensure quality attributes such as usability, efficiency, learnability and many more. Among of them, usability is the key quality attribute of any kind of software. With the same time, evaluation of usability is also necessary for improving the quality of the software [4]. Usability is one of the most important aspects of software quality, several methods have been developed in order to establish techniques capable of evaluating this attribute from early phases of the software development process [5].
Methodology
In this paper, we conduct our survey on usability of four media players i.e. VLC, QQ player, Windows media classic and Pot player on the basis of five parameters: learnability, efficiency, memorability, error and satisfaction.
Each media player is assigned its own matrix table. In this table rows present parameters of usability and columns represents the feedback of experts. Each column is assigned a value starting from 1-5. Media players have values near to 5 will be considered the best media player and the values near to 1 will be considered the less reliable media player. If the user is strongly satisfied means the value is five or closer to five and if the user is not satisfied means the value is one or near to one.
The media player will be considered the best if it scores 5 out of 5. Our evaluation technique is for a media player is adding up all the values of parameters and divide it by five e.g. 5+5+5+5+5/5=5 means strongly satisfied.
In this survey, experts provide scores to media players according to their experience mentioned in the example. For example, if a media player A scores 4.3 and another media player B scoring 3.9, the media player A will be said better than media player B.
Results and Discussions
After conducting our survey, we collect the scores of media player mentioned in section III. After collecting these values, we calculate the mean of these values by dividing the total score of media player by total number of users. We get the values of all the media players by using this method.
According to the opinion of our experts and our calculation. VLC media player has highest scores i.e. 3.66, Windows media classic placed second position scoring 3.44, third QQ player 3.18 and last Pot player with 3.1 scores. According to this survey VLC media player is more usable and a best solution for the users.
Conclusion
In this paper, the authors conduct a survey from the experts on the usability of four different media players i.e. VLC, QQ player, Windows media classic and Pot Player. Our survey parameters are learnability, efficiency, memorability, error and satisfaction. Our evaluation method was taking the mean of the score of each media player. After calculating the scores, we found that the VLC media player has the highest value and we proposed VLC media player as the best choice and solution the users.
