Improve HEVC codec parsing by writing profile compatibility flag in reverse bit order.
Why is this Pull Request needed?
The codec string parsed from hvcC boxes in mp4 init segments contained extra zeros (noticed in #7114). This change fixes the issue:
before
"hvc1.1.60000000.L150"and after"hvc1.1.6.L150"Are there any points in the code the reviewer needs to double check?
This does not appear to have impacted support checks or SourceBuffer creation on most platforms. Of the issues where these media parsed codecs were noted, none of the failures were a result of the codec string parsing as far as I know.
