[FFmpeg-user] Saving h264 RTP stream into an mp4 container

I'm trying to save incoming RTP stream into an MP4 container -- without
transcoding it. For the most part, it works well, except two problems.
First problem is mostly cosmetic: at the start of every file there's a
"Timestamps are unset in a packet for stream ...".
I don't see how it is possible to set both PTS and DTS, given only RTP
The second problem is related, but is functional rather than cosmetic:
if the RTP stream contains B-frames, whenever timestamp order decreases
-- which is normal for that stream -- the packet fails to be written,
with an error of "Application provided invalid, non monotonically
increasing dts to muxer ..."
So, the question is -- what is the correct way to assign timestamps when
muxing raw h264 frames?
