Hi, I have mencoder installed on a linux box in a hosted environment. We provide a service where schools can broadcast their sports games over the net using ustream.tv. We are getting post notifications from ustream.tv when new recordings are completed. They post us a URL to a FLV file that I download to our server. I am using mencoder to merge each new FLV together as we want our web site to show one long file. /home4/yoursch1/mplayer/mencoder /home4/yoursch1/public_html/recordings/events/final/264.flv.orig /home4/yoursch1/public_html/recordings/events/raw/18.flv -o /home4/yoursch1/public_html/recordings/events/final/264.flv -of lavf -oac copy -ovc lavc -lavcopts vcodec=flv I start with File A. When File B comes in, I merge it with A. The merge takes place and my file size is around 3.8MB. The flv plays great. When File C comes in, I merge it with A (which is now really A + B). The merge takes place and my file size is around 5.4MB. The flv plays great. When file D comes in, I merge it with A (which is really now A + B + C) but the file size drops to around 2.5MB and when viewed in a flash play is plays at like double time which to me implies something went awry in the merge. However, the log output of mencoder looks perfect, just like the other merge's. 1 duplicate frame(s)! Pos: 341.4s 13466f (100%) 84.06fps Trem: 0min 23mb A-V:-0.019 [532:47] 1 duplicate frame(s)!
