Hi, gstreamer-devel:     This is interesting. AFAIK, the OS schedules the thread/process to cpu/core in it's own logic. Is there a way to specify a cpu(core) to run a specific thread(process)? This is a OS feature or just use some special cpu instructions to achieve this?

For eg:in the HP ProLiant DL785 G5  machine(with 32 cores), only some cores are designed to have direct connection to PCI Express.  Hence a camera capture source plugin might prefer to be run in one of such cores. > > Wouldn't it be nice to have plugins to be able to specify the affinity to a certain core as a property, thereby bypassing kernel's allocation? > In other words, the thread that runs the work doing function of all the plugins that belong to the same thread, should be able to be started in the core that is specified by one of the plugins in that thread. > > Is this an item of interest in the gstreamer community? </div>Yes, I think it relates to controlling the scheduling priority of certain streaming threads, which is something we're going to try to implement in the next months.
