javacv 'Packet mismatch' when receiving stream

Basically I set up a video conference tool. Sometimes the receiving part of the streams throws a series of errors as shown below:

[flv @ 0x7fce98b6d400] Packet mismatch -1057119111 7279 2435819 [flv @ 0x7fce98b6d400] Packet mismatch -228249567 1901323 4337142 [flv @ 0x7fce98b6d400] Packet mismatch -236187797 78347 4415489 [flv @ 0x7fce98b6d400] Packet mismatch -1133241869 2064651 6480140

Does anyone have any idea what could be the issue? Video codec used: H264, format FLV. Audio codec used: AAC

Sounds like network issues?

Tried also with an ethernet cable, same error and crash, but rarely...:(

What do you mean by "crash"? If the connection breaks, simply reconnect.

This error is very frequent and don't know which causes it... I am implementing a video conference software, so it is not really easy to 'simple reconnect'

If I remember correctly, I fixed it by stay connected with a cable instead over wifi. But the root cause of the problem, remains a mystery to me.

in my situation, this is caused by the **rw_timeout** is too small. the problem disappeared when i set the value grabber.setOption("rw_timeout", "1000000"); or bigger .
