Fails.

Seeking sequentially should work for strictly P frame based codecs, but
IIRC it failed due to the PTS code in some instances.

It fails immediately for B frames as it obviously doesn't have the future I
frame to decode.

Both cases are extremely common, given that a majority of DSLR vendors use
P frame compression by default.

With respect,
