I'm recording from a D-Link DCS-2230 IP Camera with this command:
{{{
ffmpeg -use_wallclock_as_timestamps 1 -rtsp_transport tcp -i
'rtsp://admin:@192.168.1.83/live1.sdp' -dn -map 0 -codec:a libfdk_aac
-flags +qscale -global_quality 1 -afterburner 1 -ar 44100 -codec:v copy -f
segment -segment_time 60 -segment_wrap 10 -segment_list_flags live
-segment_list_size 10 -reset_timestamps 1 -segment_list test.csv -y
test_%02d.mkv
}}}
With Trunk from 2014/04/09 all works correctly and each output video is
exactly 1 minute long. With Trunk from 2014/07/18 the audio duration
slowly grows in size and the duration of each video gets 10 seconds
longer:
With 2014/04/09 trunk:
{{{
deployer at XanBox:~/test$ mediainfo *.mkv | grep -i duration
Duration : 1mn 0s
Duration : 1mn 0s
Duration : 1mn 0s
Duration : 1mn 0s
Duration : 1mn 0s
Duration : 1mn 0s
Duration : 1mn 0s
Duration : 1mn 0s
}}}
With 2014/07/18 trunk:
{{{
deployer at XanBox:~/test$ mediainfo *.mkv | grep -i duration
Duration : 1mn 1s
Duration : 1mn 1s
Duration : 1mn 1s
Duration : 1mn 1s
Duration : 1mn 1s
Duration : 1mn 11s
Duration : 1mn 11s
Duration : 1mn 21s
Duration : 1mn 21s
}}}
Any ideas what could have been changed/broken to cause this to happen?
