Carbon Coder – Windows Media installation unable execute tasks
Crew,
I have a WIndows Server 2003 installation with Carbon Coder (3.12.0.12960). It is running various tasks including converting voice recordings to MPG, DV to MPG etc. Those are running fine. One of the conversion tasks is creating WMV files but fails every job due to:
Your Windows Media installation is unable to execute the required tasks.
Please check your file and/or encoding parameters, or reinstall the Application.This is what I tried so far:
A restart of the service
A re-install of the application
A re-install of both the OS and the application
An installation a new version (3.12.0.12960)Any suggestions are welcome.

What settings are you using? What source are you using?

1. Never use FLV as source.
2. When you say ‘8kf/s’ do you mean 8 keyframes per second or…..?

Daniel,
If one does have FLV as a source are you recommending some form of transcode prior to feeding it into Carbon Coder … or is the “never use” rule meant more as a general avoid at all costs thing?
Cheers

I mean avoid at all costs. VP6 and Sorenson spark are delivery only codecs. Of course if that’s all you’ve got then you don’t have a choice, the quality will usually be rubbish.

thanks for that . yeah, sometimes you just get what you get … CC handles it pretty well but as always Garbage In Garbage Out

Crew,
Thank you for sharing your thoughts. SInce this system is serving a newsroom I don’t have control over the source codecs being fed to the Carbon Coder. Besides that the “to use or not to use FLV” is an entire different discussion. Interesting, but not very valuable to the problem at hand.
Any suggestions on the phrase:

You didn’t answer my second question relating to your settings:
2. When you say ‘8kf/s’ do you mean 8 keyframes per second or…..?

Sorry, yes you guessed right. keyframes a second.

8 keyframes per second is way way to many – you should be inserting a keyframe every 10 seconds, or once every 250 frames if you work in PAL. As you have it, the encoder is trying to set a keyframe every 3 frames.
It’s quite likely that this is what is causing the problem.
