It crashes when multi-stream opened with buffer callback occasionally.

This is something that's been fixed recently. Please give it a try with the snapshots: http://bytedeco.org/builds/

This case is different with #683.

Some codecs are also known to have issues with threads: bytedeco/javacv#1139
You'll need to provide synchronization in Java to work around those issues.

The stream is only wraped rtp with h264 codec

If synchronization at the Java level is unacceptable, make sure to report this issue upstream!
