Google Motion Photos not playing correctly

[meichthys]

Describe the bug
Google motion photos are not playing. When clicking the "Play Live Photo" button in the viewer, it appears that a few frames are played (or maybe it is just the "make animation less annoying" fix that you implemented that is making it look like it's trying to play).

To Reproduce
Steps to reproduce the behavior:

• Upload google motion photo - MP.jpg variant (Taken on Pixel 7 using Google Camera app with motion photo option turned on)
• Try to play motion photo

Sample Google Motion Photo:

Platform (please complete the following information):

• OS: Windows/Linux

• Browser Firefox/Chrome

• Version v4.13.0a1

Additional context
If i upload the photo to Google drive, the motion photo plays normally, so I know the motion portion photo is not corrupted.

can confirm, only a strange flash of frames in Firefox, it might have something to do with wrong transcoding settings

Turns out it's a bug in go-vod. It seems to select the wrong stream to encode for some reason. Should be fixed with go-vod 0.0.35
