Comment (by dseeker):

 @jkqxz yes changing the sample_aspect_ratio did correct all the frame
 encoding, even thou the aspect ratio got distorted. I'll try to get the
 value somewhere else and enforce it.

 I noted this message when trying to re-encode the file for testing, may
 have something to do with it?

 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x5598d1728000] sample aspect ratio already set
 to 93207:65536, ignoring 'pasp' atom (118:81)

 I will try to update the build, but since I'm using the hosted docker
 container I haven't a clue how to update the branch there.
