Maxim could you please, post a small example such a joining script?
Here is the sample script.
<timeline>
<group name="C:\Joined.mp3" mode="joining">
<track out_type="mpa" video="-1" audio="-1" >
<clip src="D:\Music\01.mp3" start="00:00:00:00" stop="00:04:11:22" />
<clip src="D:\Music\02.mp3" start="00:00:00:00" stop="00:04:45:28" />
<clip src="D:\Music\03.mp3" start="00:00:00:00" stop="00:05:56:26" />
<clip src="D:\Music\04.mp3" start="00:00:00:00" stop="00:05:06:65" />
</track>
</group>
</timeline>
"group name" should contain the output file name.
"clip src" should contain names of files to be joined.
"track out_type" should be identifier of the output file type. The following types are available:
mpa - for MPEG 1-2 audio files;
avi - for AVI files;
asf - for ASF, WMV, WMA files;
mpg1_sys - for MPEG 1 files.
However this method is still unsafe, because files should be verified for compatibility first. You should use it only when sure the files are compatible.
