Summary of the bug:
Trying to re-encode a video to play on an older TV and the video isn't
being decoded with the high default, which is why I'm reaching back to
more constrained profiles.
H.264 Video Encoding Guide states that:
"The -profile:v option limits the output to a specific H.264 profile. You
usually do not need to use this option and the recommendation is to omit
setting the profile which will allow x264 to automatically select the
appropriate profile"
yet this profile option does not appear to be limiting it, and x264 is
nevertheless automatically selecting an inappropriate bit depth.
What am I missing?
x264 [error]: main profile doesn't support a bit depth of 10
