Hi, all:
I am currently encoding a raw video to avi format with the example
encoding.c. It looks that example uses a constant bitrate for video
encoding but that is not what I need. Is it possible to use adaptive bit
rate with a constant quality instead? If yes, how can I do that with
FFMPEG

No, only for encoders that produce broken pts/dts.

Do you mean add 1 directly onto original PTS?
So
pts = 0, dts =

Add max_bframes (1 in your case) to pts.

Hi Guys,
I'm using Window Media Foundation H.264 encoder to encode video frames and
use ffmpeg as a muxer.
The frames returned by the encoder has following timestamps
pts = 0, dts = 0
pts = 2, dts = 1
pts = 1, dts = 2
pts = 4, dts = 3
pts = 3, dts = 4
pts = 6, dts = 5
pts = 5, dts = 6
pts = 8, d
