Thank you very much for all the information. <br />I should have checked all the information of your project and I would have found that the decoder only supports the baseline profile. Sorry for the incovenience caused. Nevertheless, I have tested other high profile sequences and, for example, the SVCHICS-1 sequence seems to go well.<br /><br />Thanks again and congratulations for yor project!<br />Ana<br /><div style="font-family: 'Times New Roman';

I use MinGW to execute Mplayer. <br />Furthermore, it is not only the problem that I can not see the video. If I try to convert it to y4m by the following:<br /> <br />mplayer video.mp4 -fps 30 -vo yuv4mpeg:file='video.y4m'<br /><br />it doesn't create any file y4m.
