Comment (by sinkers):

 Original report failed to provide file info and returned an error only:
 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7fa82c005200] Could not find codec parameters
 for stream 0 (Video: h264 (avc1 / 0x31637661), 512x288): unspecified pixel
 format

 Comment:1 shows the metadata correctly

 I am assuming the change in comment one is as commented which is removing
 the check for pixel format in the mp4. I haven't checked the mp4 spec but
 as this is a valid DASH init.mp4 file I am assuming it is correct and as
 such that pixel format is not a required field in an mp4.
