Comment on Using Java to get detailed DNS information by Jeff Gonzales

I figured out my issue. It was a permissions setting I needed to change. I can do some lookups but now I get a null pointer exception when trying to do a reverse lookup. Any ideas?

@Peter There may be but I haven't noticed any problems after an fsck so it is hard to tell. Either way you would probably be OK.

Thanks, Carson. This post was very useful to me.

Is there a one-off error in the count parameter to your dd command (because the end sector number is inclusive)?

Hi,

thanks for the article. I'd be very interested to hear any thoughts on solving a problem I'm seeing with my segments. (I've built with ffmpeg version 24035)

When I play back the segments, the video track starts playing ahead of the audio. In other words, the first couple of seconds of the video stream are not playing back, so the video stream is ahead of the audio stream. The audio and video are in sync when I play back the input file. (tested on multiple videos/formats)

Any thoughts on what could be wrong, or how to resolve?

Thanks for any suggestions.

Any way to build segmenter with static libs embedded like ffmpeg "./configure … –extra-libs=/tmp/segmenter/lib/libfaac.a –extra-libs=/tmp/segmenter/lib/libx264.a –extra-libs=/tmp/segmenter/lib/libxvidcore.a –extra-libs=/tmp/segmenter/lib/libmp3lame.a

I haven't had a reason to try but I can imagine that there might be some restriction. You may try to force the DNS lookups to using TCP if you can.

Comment on Installing Cent OS 5.5 on EC2 with the Cent OS 5.5 Kernel by carson

1) There are probably multiple ways of doing it but I didn't have time to verify them all so I went with the way I know will work. Downloading the modules from Amazon would not work however.
2) My build script may not work but if you have a running instance you should be able to do yum update and have the new kernel install without a problem. You would need to modify the menu.lst file to point to the new kernel and initrd file as well. A reboot would then get you on the new kernel.
3) I haven't been able to do anything with virt-manager yet but I bet it would work and probably make things simpler.

Not sure what the problem might be with Safari but Firefox won't play this type of video. Firefox doesn't support the codec for one and they don't support Apple's streaming either. If it plays in VLC then it is probably a matter of getting the correct video tag working for Safari to work.
