HandBrake

-C2 etc don't do what you seem to think they do. You don't need to do anything to maximize CPU usage. HB will run all the threads it can, and your CPU will respond appropriately. More used cores is almost always better since the increased cycles per core are so small. I think -C2 tells Hanbrake to ...

I've got a new-ish AMD 1055T. It's got six core, but also have the AMD Turbo Core feature. As I understand it, this feature will overclock three cores, and underclock the other three cores if all six cores aren't "active". How well does handbrake scale across multiple cores? Where's the po...

As a followup, this was overheating. I replaced the heatsink/fan combo with something that blows down and creates some airflow over the components right around the CPU socket. I've run the exact same encode and several others without any trouble.

FWIW, there is no code in the CLI or libhb that can trigger a reboot directly. The GUIs have some code that can attempt to shut down the computer at the end of the queue (but that code will never be reached mid-encode anyway). Right, "reboot" was the wrong term. Sudden crash is more accur...

Yea, overheating was it. Something has changed since I first ran CPU burn when installing the new CPU, I'll have to debug that. It's clearly not Handbrake, sorry for the false alarm. So, does anyone know what "temp3" might be? It's off the chart: temp1: +35.0 C (low = +127.0 C, high = +127...

No, I'm not completely sure. That was my first thought when this first happened eight months ago. I thought running CPU Burn on all six cores would have eliminated overheating as a possibility, but I'm open to other tests. How should I go about determining this? I guess I could just run "sensor...

I run HandBrakeCLI on a headless home server (Ubuntu 10.10 64-bit on a 6-core AMD 1055T with 8GB of RAM). Over the past couple of days I noticed that Handbrake 0.9.5 transcoding a Blu-Ray source will cause the machine to reboot suddenly. There is nothing obvious in syslog, just regular logging then ...

I'd vote for this as well.

I'm increasingly using handbrake for m2ts files.
