nice project but it would be good if you can make other codecs like h.264 etc. optional it will increase its adoption and help in battle testing entire framework.

Thanks for the suggestion. H.264 Baseline/High profile patents are largely expiring between 2027–2028, with a few stragglers potentially lasting until 2030. We're tracking this closely — once the patent landscape is clear, we plan to offer H.264/H.265 as an optional feature. In the meantime, AV1 matches or exceeds H.265 in compression efficiency, so for greenfield projects there's little reason to reach for the legacy codecs.

problem is users will still have files in mp4+h264 combo we cannot dictate that but i think i can workaround that by using system default codecs via other library.
