> Jean-Yves - Do you have a vague ballpark memory number for this?

In regards to how much memory this could use or how much memory it would save in each content process?

Memory use will be dependent on how many decoding tasks are active at any given time and how big the video frames are going to be.

I also expect a hit on performance at first as we would need an extra copy that we need know.

Currently, the ffmpeg video decoder for example, directly upload the YUV image straight from the ffmpeg decoder into a D3D11 surface.

Would need to implement similar tricks with the RDD (RemoteDataDecoder) process.

How much it would save in each content process.

Do you have an estimate for one decoder, or examples of a few? It would help prioritize this from a content memshrink point of view.

Each content process create several SharedThreadPool made each of 8 threads with a set stack size of 256kB.
This big stack size is needed as we call external framework.

We would only need those type of threadpool in the decoding process.

It really depends on use, having said that a fair amount of content are using animated videos....

The best answer will be that we can do some measurement once we have the prototype running.

Comment 5

[Eric Rahm [:erahm]]

Okay, so a low end estimate would be something like 2MB just for the threadpool. This probably won't show up in our baseline tests as I assume the threadpool is lazily instantiated.

[Anthony Jones (:ajones, :kentuckyfriedtakahe, :k17e)]

Sinewave tables and the ffmpeg library relocations also use memory.

Hey all, this should emulate GMP settings vs. GPU, with modifications as needed depending on what breaks. GMP hosts drm media plugins and is heavily locked down. We should start with those settings and see how much we can keep. GPU isn't locked down much at all due to various issues with 3rd party 'stuff' that loads there (drivers, vr, fonts, etc.).

Comment 21

[Michael Froman [:mjf]]

Jim - we're opening a follow on bug for all the proper sandboxing.  This is here specifically because it matches the GPU process that all of this was based on and without any sandboxing Shmem failed to allocate in our new process.  Is this an accepted very short term solution?

> and without any sandboxing Shmem failed to allocate in our new process.

FYI, shared memory allocation in the child process is potentially a problem, at least on Linux: it's implemented by opening files, so the process would need limited filesystem access instead of none.  GMP has the plugin process request that the parent do the creation[1][2] in order to deal with this (using sync IPC, which we generally try to avoid if possible, because it was kind of glued in after the fact), and then it has a cache on top of that (which if I recall correctly was also to help with the performance of creating/destroying 3 shms every frame).

On Linux we can use the same file brokering we use for content processes if needed, but it increases attack surface; I don't know what if any issues there might be on other platforms if we want at least as much sandboxing as GMP.

(To make this more confusing, bug 1440203 will allow sandbox-friendly shared memory allocation on Linux kernels since 3.17, released October 2014… but that's only 85% of our Linux userbase, so we'll still need a fallback for the foreseeable future.)

Well, currently this code runs in content so essentially we're downgrading the security construct this code runs within. Should we try to match content at least? It's pretty easy to flip these switches and push to try to find issues. We know the code works under the content process restrictions which are weaker than the GPU settings.

Jim, we're not planning to pref on until the full sandboxing bug (Bug 1498624) has landed.  Does that change anything for you?
