Description
I noticed that DALI (Apache license) has a custom logic for detecting keyframes in H264 and HEVC formats, when they're building the frame index. We should look into this and see whether it's worth implementing something similar.

Research direction
Review DALI's custom logic in dali/operators/video/frames_decoder_base.cc, lines 328-374, and compare it with torchcodec's frame-indexing path for H264 and HEVC. Determine whether similar keyframe detection is worthwhile; done means reaching and documenting a clear implementation decision.
