How to solve ffmpeg and ACTi camera ip problem?

Question

fmpeg

I have a problem with broadcasting from an IP camera stream.
Initial data:
There are cameras ACTi E13, E32, E53.
There is an Ubuntu 13.04 server (ffmpeg on board).
When starting the broadcast, ffmpeg gives an incomprehensible error about which the Internet actually knows nothing. Here is
the full code:

ffmpeg -i "rtsp://user:[email protected]:7070/track1" -i "rtsp://user:[email protected]:7070/track3" -s 1280x720 -trellis 2 -vcodec copy -acodec copy -f flv "rtmp://127.0.0.1/live/cam2"

As I understand it, the problem is still in the cameras, because. other models work (not ACTi)
Everything happens at the 30th second (before that, the broadcast is flawless)

[flv @ 0xff5000] Failed to update header with correct duration.
[flv @ 0xff5000] Failed to update header with correct filesize.

And on this error falls down. Tried all sorts of interpretations of using keys. Nothing helps. AVCONV even refuses to start.
FFMPEG today updated from GITa, before that it was 0.9.
Question: Is it possible, at least with crutches, to make ffmpeg ignore the error.
