[Libav-user] Encoder / muxer timings

[Charles]

Do frames going into the encoder need to be time stamped? With a real clock timestamp?
I was under the impression setting the pts to current frame count was enough, the encoder already has the time scale.
   I adjust the packets TS after avcodec_receive_packet via av_packet_rescale_ts
I am definitely getting studder in my encoding and occasional step-back.
Any pointers would be appreciated.
Thanks
