ffmpeg (libx264) skip frames

Description

I use ffmpeg with nginx-rtmp-module.
ffmpeg (libx264) skip frames when transcode video from rtsp to (h.264) flv. In VLC rtsp plays coorrect. Tried a lot of parameters. With this -use_wallclock_as_timestamps 1 works better. But a lot of skips stayed.

How to reproduce:
