assign audio files to mp4 files automatically

Q1: I have a folder have song filename formate like Video: song1.mp4 Audio left channel: song1.mp4.mv1 Audio right channelsong1.mp4.mv2 Is there any ways can allow bsplayer to preload all audio in the video so I dont need to play each video and assign both left and right audio manually? Q2: thinking to use php to write a system to control the bsplayer(such as add song to playlist, stop and play video, switch audio channel or play next video, any hints or php is impossible? Thanks.

Options -> preferences -> audio -> auto load external audio files ?

But this auto load only support one audio file(i have 2 audios files) and i need to modified the audio same name as video. All my audio file name is name.mp4.mv1 and name.mp4.mv2

As far as I can see, BSPlayer can be aware of only 1 audio file. Maybe it will be a good ideea for a Feature request, smth like audiofile-left.mv1 audiofile-rigth.mv1 to be used as syntax. Close to using 2 subtitles with different language.

Any command live method to start a song and load a specific external audio ? Also any cmd method to add song to playlist ?

ini help? 

i have read from BSplayerPro/doc/ini_files.html and create a .ini or even .bsl file with below content but it not working. Directory=. FName=name.mp4 AudioFile1=fileA.wav AudioFile2=fileB.wav or even below not working too Directory=. FName=name.mp4
