Every requested read will eventually be completed, writing the result to `read_result`, either `S_OK` or an error. If a stream was selected and a read requested to it, then later becomes deselected, we will consider it a valid thread wrt sample delivery until it completes its read and writes to `read_result`. It may complete it with a sample if the deselection happened late, or with an error if its read was interrupted. `read_requested` is a one way flag to tell reader to start reading. It needs to be reset before the `GetNextSample` call, and checked again on return to correctly synchronize flush and read requests from the callback thread, for instance when seeking. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1311#note_15905

I believe I did and it still applies (with the same offset as without threads, when samples are decoded), and there's another setting named `DeliverOnReceive` that is the one which changes that behavior (though I don't think we need it). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1311#note_15901

Because this is a blocking call, which can call application callbacks, or otherwise also blocking until there's a sample ready. We want to be able to deliver samples from the callback thread, on other streams, without being blocked and without blocking the reader. There's no point in making all this asynchronous otherwise. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1311#note_15902

The most common case where this happens is on EOS, I don't think we want to print error. When streams are deselected this would happen as well if it interrupts the wait on buffer. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1311#note_15903

No, it's checked outside of the loop to see if all streams have received EOS (in which case `hr == NS_E_NO_MORE_SAMPLES`), or if there's still some streams with pending requests or pending samples to deliver (`hr == E_PENDING`). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1311#note_15904
