VLC player for iPhone 5 only plays sound?

So I was download Spongebob season one the other day as I'm in love with the series. Anyway. I figured that it would be easier to download VLC player app for iPhone than converting the.avi files to.mp4 files. As I was going to bed, ready to enjoy some spongebob I realized that the video didn't play, only the sound. So my question is: How do I fix this?

Added (1). I downloaded it as torrents from www.thepiratebay.sx, not from youtube or some other place.

If you download it from youtube. Download it with interner download manager. You can choose to download as mp4.

  • Why is no sound coming out my iPhone. The only sound that comes out is the ringer or when I have headphones hooked up? I have a iPhone 6s. And I recently noticed that no sound is coming out my iPhone. The only sound that works is my ringer and when I have headphones hooked up. My phone is updated to the IOS 12. I tried cleaning out my headphone jack and speakers and it's still doing it.
  • Static when sound plays on laptop? 8 hours ago my computer was fine. I closed it for the night and didn't turn it on until 9 this morning. There's suddenly this mild but annoying static noise occuring when sound plays through the laptop speakers and through my headphones that I plugged in, so I'm pretty sure it is not a hardware issue. My laptop is an MSI gs70 laptop. I tried the headphones in my iphone and they worked fine, so I know the headphones aren't messed up.
  • Quicktime lags and VLC plays iphone movie sideways. What can be done in either case? So I had my son take a short vid with his iPhone and transferred it to my HD. When I played it with VLC (or others) it plays sideways. Speed is normal though. Then I played it with QuickTime and the vid played normally (Portrait) but the speed was too slow. QT is lagging. Any help with both issues would be appreciated. Thanks to all. BTW would I need to upgrade codecs?
  • Only one speaker on my iPhone 4s plays music? I'm new to iPhone's, and I just got this phone 3 days ago. I have never dropped it, but it sounds like only the right speaker on the bottom of the phone plays music. Is this normal? Should I get it checked?
