I have tried transcoding plugin with two CUDA card (GeForce GTX 580) on server
Source: FMLE and osprey 230 card
When I run two transcoding sessions at the same time, everything worked fine.
When there were three concurrent sessions, wowza crashed after few seconds after its start.
There was no error in errorlog, except for
LiveStreamPacketizerSmoothStreaming.handlePacket[CT24/_definst_/ct24live1.sdp_144p2]: Timecode out of order [video]: 790000:810000
But it sometimes occured even without three concurrent transcoders
Unfortunetely I do not have the server anymore, so I cannot do any another test...
My question is: Are multiple CUDA cards supported with wowza? Do you use "a standard CUDA framework for Java"? May be I could find some informations there...
