question about k-lite ; " options > playback > open settings "

[Mohammad48]

can anyone tell me what does " use worker thread to construct the filter graph" do?
thanks

Playing a video in Windows involves constructing a chain (graph) of components (filters). You need a Source Filter that understands the container (AVI, WMV, MP4, MKV, etc.). Then a Splitter to separate the audio and video into individual streams for further processing (often the source filter and the splitter are the same filter) Then decoders to decompress the audio and video streams. Maybe a Colorspace Converter to convert the video from the decompression colorspace to a something the graphics card understands. And finally audio and video Renderers to put send the audio to the sound card and the video to the graphics card.

Using a worker thread to build the graph prevents the player from locking up if the process of building the thread locks up for some reason.

and what is the "worker thread"?

and what is the "worker thread"?

A separate thread just for creating the graph, separate from the main program thread.

(This OT is absolutely necessary)

"worker" thread? Yes, the commies are everywhere

computer "science" <= yet another misnomer Actually it's just an «art» —
and a bad art, which still has many idiocies from the 7-bit era

Indeed!

Even computing science, e.g the science of computing things, is not really a science, just like math is not a science. After all the term "empirical science" is just a pleonasm.

However there may be a compelling question whether quantum computing could be considered science.

Hmm...
