Hello. I'm having trouble using avconv. My problem - is recording video with IP-cameras (used j2000-ip).
Record directly from the camera impossible, because it is restriction on 3 RTSP session (first to relay live video, second for administrative staff, the third - reserve). Software is used to relay live video - erlyvideo http://erlyvideo.org. Recording is performed as follows: ======== recorder@cctv:~/records/records$ avconv -i rtmp://cctv.lo.ufanet.ru/live/demo2 -vcodec copy -an -sn -map 0 -f segment -segment_format mp4 -segment_time 60 -y 'stream-%03d.mp4' avconv version 0.8.1-5:0.8.1-4, Copyright (c) 2000-2011 the Libav developers built on Mar 30 2012 14:37:42 with gcc 4.6.3 HandShake: client signature does not match!

But unfortunately the record does not work as expected. The first segment able to play successfully in Flash (PC, Linux, Mac) and QuickTime (iOS), but subsequent segments are played back only in Flash, QuickTime simply displays a black screen. An example of RTMP input stream: rtmp://cctv.lo.ufanet.ru/live/demo2 Sample entries: http://cctv.lo.ufanet.ru/cctv/ Tell me, what could be the reason why that is received by the segments (except first) do not play QuickTime (both iOS, and on Mac OS X)?
