<div class="moz-cite-prefix">Hi all,<br>
I will respond to myself to because i forgot to mention. The
camera produces good and working H264 stream.<br>
Proof: <a class="moz-txt-link-freetext" href="http://www.speed666.info/testok.h264">http://www.speed666.info/testok.h264</a><br>
I can record it via openRTSP command from different host without
problems so it looks like compiler or linux limitation - but where
to search?<br>

<br>
I wanted to ask You because i have no idea where the problem may
sit.
<br>
I have compiled openRTSP which i use to dump H264 streams from
RTSP server over localhost
<br>
This approach works fine in many IP Cameras that i use for my
purpose. Suddenly i found a device that producest wierd files.
<br>
<br>
Incomming buffer size by default is 100000 - and everything works
great as soon as I frame is not larger that that.
<br>
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.
<br>
<br>
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.
<br>
<br>
Produced files:
<br>
<a class="moz-txt-link-freetext" href="http://www.speed666.info/good.h264">http://www.speed666.info/good.h264</a> - this is below 100000
limit
<br>
<a class="moz-txt-link-freetext" href="http://www.speed666.info/bad.h264">http://www.speed666.info/bad.h264</a> - this is bitrate where
buffer is too small
<br>
<br>
I tried to increase buffer size but this only produces bad files -
nothing more.
<br>
<br>
Where i should search the problem. Same binary running on
different camera with same CPU works well. Any clues?
<br>
