[Libav-user] Can I skip some packets when decoding

I have a question about read frame,

Suppose I've just opened a file, so the readpointer is at the beginning of
the file.

Compare these two methods:

1. call av_read_frame + avcode_decode_video2 to decode 100 video packets(
suppose each packet can decode into a frame)
2. call av_read_frame, but only decode the 100th packet (all previous 99
packets are just discarded)

Will the 100th frame from method 1 and the frame from method 2 have same
content, timestamp, etc?
