Video timestamps in the first second (about 25fps) are something like this:

dts:36,diff:36,
dts:76,diff:40,
dts:70,diff:-6,
dts:110,diff:40,
dts:190,diff:80,
dts:214,diff:24,
dts:252,diff:38,
dts:372,diff:120,
dts:412,diff:40,
dts:324,diff:-88,
dts:412,diff:88,
dts:532,diff:120,
dts:508,diff:-24,
dts:550,diff:42,
dts:574,diff:24,
dts:566,diff:-8,
dts:606,diff:40,
dts:758,diff:152,
dts:734,diff:-24,
dts:726,diff:-8,
dts:830,diff:104,
dts:852,diff:22,
dts:828,diff:-24,
dts:948,diff:120,
dts:990,diff:42,

Agree,  I'll take a deeper look into this issue and share with you later.
Thanks~
