I don't think there is a "drift". The timestamps are just increasing too fast. This is reproducible with old versions of FFmpeg (back to 0.9) and I cannot play the stream at all with vlc. In addition, we have a file output from another Hikvision server here that has broken timestamps so I am tending to a server issue. As a work-around, you can record the stream with something else than ogg (for example avi) and then re-encode that file, the result should contain sane timestamps. If you use the option "-rtsp_transport tcp" you should not see the errors that are in your console output, "-qscale 2" ensures maximum quality, you can reduce the bitrate when encoding to ogg. Not necessarily related: Encoding to mkv-vpx-opus should produce smaller and not less compatible files.
