1. When using framerate conversion (increasing framerate), I found that the idx1 chunk has somethings wrong.
For drop frame, normally is
"00dc", 0, start location of the chunk, length of the chunk
But in the drop frames just after a keyframe, wrong field appear:
"00dc", 16, start location of the chunk, length of the chunk
This causes errors for opening the movie in some program like VirtualDub 1.4.13 (the error drop frames are stated as keyframes and decode wrongly when passing left key at second keyframe)
2. Framerate conversion calculation bug:
I try to convert a 29.97 fps video to 119.88 fps (delta/key : drop = 1:3)
The first 10 output frames are:
0 key
1 key (drop)
2 key (drop)
3 key (drop)
4 drop // I don't know why insert drop frame here.
5 delta
6 drop
7 drop
8 drop
9 delta
