MPlayer FAQ and Setup

(i) Sound and video are not synchronized
MPlayer in order to better interpret the image, the default is not to drop the frame. However, if your hardware (graphics card) is not strong enough, the image processing can not catch up, and do not let drop frames, it will cause the image behind the sound, that is, sound and image are not synchronized.
There are three modes of mplayer drop frames, no frames dropped, frames dropped, forced drop frames. The default is not to drop the frame, we set to drop the frame on it, forced to drop the frame is generally not recommended.

To resolve this issue, add the following line to the configuration file
FRAMEDRP = yes to modify the global configuration file (/etc/mplayer/mplayer.conf) or to modify the user profile (~/.mplayer/mplayer.conf).


(b) The graphical interface does not open the video
After updating the MPlayer, double-clicking on the video file (under the graphical interface) and right-clicking the video will not open it, and the error content is similar to the following:
Failed to open file:///path ... But it can be opened in the terminal.

The workaround is as follows:
Edit File/usr/share/applications/mplayer.desktop
Find the sentence Exec=gmplayer%u, remove the final%u or modify it to%F.

(iii) Unable to open RVMB video
AVI, DVD and so on format can put, just can't put RMVB, RM and other formats, reported similar to the error:
Cannot find codecs matching SELECTED-VO and video format 0x30345652
First of all, it is possible that there is no binary decoding file such as RMVB, go to MPlayer's home page next on it.
After the completion of the step, if there is this problem, it is possible that you can not complete the decoding file, in the terminal run MPlayer, get detailed error output, to see exactly what the missing file, and then to find this file. (Many of the Internet is missing drv43260.dll files, will be placed in the corresponding directory of decoded files, the default is the/usr/lib/codecs directory)

In fact, through this problem, can be summed up a problem-solving method:
First, get as much detailed error output as possible, such as go to the terminal to run the program.
Second, the analysis of errors, if they can understand, according to their own understanding to deal with, see whether the problem can be solved.
Again, look at the help and instructions provided by the program, understand the software, and then understand the error message.
Finally, Google online.
