Frames Recorded out of Sequence?

Question

I'm having a problem with frames being recorded out of sequence in both the ffmpeg-generated video files and the jpeg snapshots. Timestamps go in order, but things jump backwards and then forward again.

I'm using a Toshiba network camera -- I suppose it is possible (though it seems very unlikely) that it's caching images somehow and spitting them out out of order.

I can send examples if you like.

Environment

Motion version:	3.2.1
ffmpeg version:	0.4.9pre1
Libraries:	ffmpeg, mysql, postgresql
Server OS:	Fedora, CentOS (happens on both)

Answer

The problem is most likely in the Motion netcam code.

Someone will start looking at this again now.

I do not think you can do anything in your setup but any observations you can add that triggers the event is very welcome.

A bug was just filed with same problem and also with a Network camera.

It is interesting to see that it is always a single frame that is inserted wrong. Never two and then two. That confirms to me that it is the buffer in the netcam thread that does not communicate correctly with the camera thread.
