Most of it has been posted earlier actually, but let me summarize it. By default, your script will run in single-threaded mode, just like with SEt's build. Also, just like in SEt's build, you'll have to make sure that filters use the correct MT mode, or else they might wreak havoc.

There are three basic MT modes 1,2,3 and an experimental workaround mode 4 since r, and modes are the same modes as in yeah you guessed correctly SEt's build.

Which means you can use the same modes that you have used with AviSynth-MT. This meant if you needed to use multiple MT modes, you had to insert all those calls in the middle of your script, littered over many places. This means you can specify all the MT modes at the beginning without polluting your script.

You can even make a SetMTMode. This is much cleaner, and it allows you to maintain all your MT-modes centrally at a single place. Enabling MT The other difference is how you actually enable multithreading. Uhm, onto the point: You enable MT by placing a single call to Prefetch X at the end of your script, where X is the number of threads to use.

If there is a return statement in your script it must be placed after Prefetch.

Example This line causes all filters that don't have an MT mode explicitly use mode 2 by default. Mode 2 is a relatively safe choice until you don't know most of your calls to be either mode 1 or 3.

Compared with mode 1, mode 2 trades memory for MT-safety, but only a select few filters will work with mode 1. If it sees a source filter which has no MT-mode specified at all, it will automatically use mode 3 instead of the default MT mode.

The script is a work-in-progess, there's still lots of plugins that need to be tested and validated.

When the script is finalized, the only thing the user will have to write in his script is the Prefetch call, all SetFilterMtMode calls will be hidden in a single. You can find the latest revision here: Report any issues here.

Choosing the correct MT mode Please do check if the actual output is correct. Fast but corrupted output is useless. Easy way of checking would be using something like ColorBars, "YV12". It doesn't always work right but will do for most stuff. Some filters like nnedi3 use some buffers to do their dirty work and with mode 1 you get multiple threads writing data from different frames to the same buffer.

This causes corruption when later someone tries to read from this buffer and gets not what was expected. Most of the "more complicated" filters use some kind of temporary storage thus won't work well with this mode.

Mode 2 doesn't have this issue because multiple threads will get their own buffers and no data will be shared. Hence mode 2 is the "default" mode which should work with most filters, but it wastes memory like crazy take SangNom2 for example - for p YV12 frame, size of temporary buffers is about 10MB, so with 4 threads you get 40MBs on single filter invocation.

Now add some usual supersampling to this and multiple invocations in most aa scripts and If the filter requires sequential access or uses some global storage, then mode 3 is the only way to go.

If "width" is not given either, then SR will just double the resolution. Loads so-called AviSynth C-plugins. C-plugins are created in pure C (unlike most Avisynth plugins, which are created with MS C++), use a special C API, and must be loaded with LoadCPlugin.

LoadCPlugin(string filename). All external plugins should #include it. External plugins do not link with metin2sell.com, so they can't directly access functions that are defined in the main Avisynth source code.

Therefore, every important function in avisynth.h is either defined inline or declared as virtual. The virtual functions act as callbacks for external DLLs.
