Hi all,
I will respond to myself to because i forgot to mention. The camera produces good and working H264 stream.
Proof: http://www.speed666.info/testok.h264
I can record it via openRTSP command from different host without problems so it looks like compiler or linux limitation - but where to search?

Hello,
I wanted to ask You because i have no idea where the problem may sit.
I have compiled openRTSP which i use to dump H264 streams from RTSP server over localhost This approach works fine in many IP Cameras that i use for my purpose. Suddenly i found a device that producest wierd files.

Incomming buffer size by default is 100000 - and everything works great as soon as I frame is not larger that that. Normally if i put bitrate like 4-6 Mbits, IFrames are bigger and then i increase buffer size to 300000 in example and everything works fine.

But this time - the exported file is broken. Not playable and its structure looks broken. In meantime live view can be perfectly playable via VLC over RTSP.

Produced files:
    http://www.speed666.info/good.h264  - this is below 100000 limit
http://www.speed666.info/bad.h264 - this is bitrate where buffer is too small

I tried to increase buffer size but this only produces bad files - nothing more.

Where i should search the problem. Same binary running on different camera with same CPU works well. Any clues?
