I have about 700+ mp4 videos of a friend's music. I recently learned that Audio station can be setup to play through Alexa. However, Audio station does not play MP4s unless I have it setup wrong. Is there another app from Synology that can or is there a way to mass rip the audio out of the mp4 to a format that audio station can play? TIA
 
You have to help me a bit,
MP4 is a container, it is mainly used for video, text etc and not particularly used or useful for audio, an contents and compression may vary.
As I recall video station can play most of them using the multimedia extension package.
MP4 is not supported for audiostation, as far as I can see. Makes sense as most audio is Encoded differently.
So my question: what is in your MP4? Just music ?
You can search for conversion tools MP4->MP3 online like shutterencoder.com

Audio Station plays audio.

After mucking about with ffmpeg with videos to make subtitles work better for me, what I've found is that there are a number of ways to construct commands but this one should work. You would have to work out how to use it to loop through all 700 videos.

ffmpeg -i myfile.mp4 -map 0:a -c copy myfile.m4a

This assumes there is only one audio track, since the -map command says to use all the first file's audio streams. Then the -c command is instructed to just copy all mapped streams to the output file. This just extracts the audio and puts it in a new wrapper, there's no ripping or degrading.

You can use ffprobe command to get details of a file and what streams it contains.
 
Thanks EAZ1964 and Fredbert. I found a program that is working titled Adapter which also states it can do bulk files as I have roughly 700+ mp4. Not too sure about doing all of them though!!
