Description

#curl http://127.0.0.1:80/test.mp4?start=10

if start=10 is not the site of keyframe, the mp4 may have abnormal such as no picture before N second,or screen blurred.

I think the solution is to add the following step:
(1)stts:forcast the nearest sample on the basis of start=X
(2)stss:find the nearest keyframe sample on the basis of step (1)
(3)stts:find the nearest start arg on the basis of step (2)

Resolution: wontfix
Status: newclosed

This is expected behaviour. The mp4 module do not try to search for and/or introduce additional key frames, it expects a player to do requests to appropriate key frames instead.
