FAQ

Where’s the magic? How does it work?
After booting up, it will run the mp4museum.py script from the pi home directory. Feel free to hack! Take a look into the main script on GitHub.

How do I login?
Connected to a Network providing DHCP, you can use SSH, User pi, Password mp4museum (see HowTo: Hack)

Would it play video files from SD Card?
You could use just the master for mp4museum-sync, but it will support only one loop. See above to login and make changes to mp4museum.

How do i connect those switches?
Add a regular (closing) switch between +5V and pin 11 or 13 for pause or skip. See it here.

Can it play an seamless loop?
You could try the master for mp4museum-sync. 

I have analog out problems
Get an Hifiberry or PiAudio Board to get proper analog audio. These can be installed in mp4museum by adding just one line to “config.txt” on “boot”.

It is possible to use USB audio interfaces, as long as they don’t need special drivers. You would need to change your alsa.conf default interface number.

Problems & possible solutions

USB Stick Format: Use a Flash Drive, and not a Harddisc. FAT32, HFS, NTFS supported.

Check the LED’s: Red steady = Power Good, Green flickering = Booting / Working, Green steady = Boot Issue / SD Card Problem

No sound or image on hdmi? Check this out to learn about setting up config.txt.

AV Check (V3 and later) During logo playback you should hear a film projector sound. Also, there are thin orange lines in all four corners- if you cannot see them, check your overscan settings.

Hardware Problems: Needs good power: Original Raspi, maybe Apple iPad Charger. HDMI output is not very capable, stick to one cable between Pi and Screen/Projector, also, keep it short.

White/Green Screen at the end of Video – This could happen if the omxplayer app has problems with reading your file. Try to encode your .mp4 using a hight-quality preset in handbrake.
