I’m trying to output mp4 clips via Blackmagic i/o card
everything works perfectly for a while, after a few hours (possibly a day) - the audio stops playing,
video still playing, but all outputs of the blackmagic have no audio.
I restart the casparcg server, reload the clips and the audio works again for a while till it happens again,
what would be the right way to start debugging that?
it’s different clips everytime, all 3 outputs I use stop providing audio at once
I couldn’t find any errors in the log prior to the audio stopping,
When I noticed the issue I shut down the casparcg server,
in the log it says:
[2023-07-31 13:27:25.647] [error] DeckLink Duo 2 [3-3|1080i5000] Failed to schedule audio.
[2023-07-31 13:27:25.647] [info] DeckLink Duo 2 [3-3|1080i5000] Scheduled playback has stopped.
but I don’t know if it’s normal, might be a normal shutdown behavior (?)
there’s another warning a few hours earlier but I’m almost sure the audio worked after that:
[2023-07-31 06:52:43.122] [warning] DeckLink Duo 2 [4|1080i5000] in-sync changed: -0.556896
[2023-07-31 06:52:43.170] [warning] DeckLink Duo 2 [4|1080i5000] out-sync changed: 0.02
[2023-07-31 06:52:43.205] [warning] DeckLink Duo 2 [4|1080i5000] out-sync changed: 0.04
[2023-07-31 06:52:43.644] [warning] DeckLink Duo 2 [4|1080i5000] out-sync changed: -0.158021
do you think that those messages contain any valuable information?
We have 2 machines, one with genlock, the other without
it happens on both, I’m not sure it’s genlock related…
I can tell you that the switcher that the SDIs are connecting to is shutting down every day,
Not sure if this could cause such a behavior
yeah, I guess you’re right,
I have no explanation for that,
after a few days of work I can say that we still lose audio after 15-20 hours since startup,
restarting caspar server solves the issue for an hour or two,
Rebooting the whole machine fixes it for the next 15-20 hours
