Because it isn't something that should be marked as a keyframe as coded
bitstream in any kind of container, like it's the case of mp4 sync samples.
MPEG-TS Random Access Indicator expects keyframes to be signalled like this.
With intra-refresh and this code removed, there will be no random access
points at all.
If MPEG-TS wants to tag packets containing things other than IDR access
units as RAPs, then it should analyze the bitstream itself in order to
tag them itself as such in the output.
This parser as is is generating invalid output for other containers that
are strict about key frames, and signal recovery points (like those
indicated by the use of this SEI) by other means.
