It can split the mplayer status line into lines.
|
|
It also provides some Qt 3 like functions like addArgument().
|
|
|
|
There are two working modes, controlled by the USE_TEMP_FILE define.
|
|
If USE_TEMP_FILE is 1 it will send the output of mplayer to a temporary
|
|
file, and then it will be read from it. Otherwise it will read from
|
|
standard ouput as usual.
