 > Yup, that would work. But you would need a different bitstream filter
 for each video codec.

 For codecs, you need MP2 video, H.264 and HEVC. For the latter two, the
 bitstream also differs depending on the container, whether it's mp4 or
 mpegts (Annex B), so there's already 5 different cases to handle when
 implementing a bitstream filter for this.
