Describe the Bug

During the development of #4931 I've noted a segfault when trying to switch between displays very quickly (by button mashing the switching shortcut to the same display, e.g. CTRL+ALT+SHIFT+F1).

This can be reproduced consistently with not only portalgrab but other capture methods (tested KMS) as well (at least on linux). It is also occurring regardless of encoder (tested vulkan and vaapi).

Expected Behavior

Sunshine should not crash when switching screens too quickly.

Additional Context

In video.cpp the switch_display_event is popped before the reset_display call has even started. Which would allow the display reset to be stacked onto another potentially leading to this issue if I'm understanding this correctly:

Sunshine/src/video.cpp

Lines 1478 to 1484 in b172a98

	// Process any pending display switch with the new list of displays
	if (switch_display_event->peek()) {
	display_p = std::clamp(*switch_display_event->pop(), 0, (int) display_names.size() - 1);
	}
	// reset_display() will sleep between retries
	reset_display(disp, encoder.platform_formats->dev_type, display_names[display_p], capture_ctxs.front().config);

Changing this to finish the switch_display_event after reset_display has concluded might fix the issue. Also not sure if it is desirable to do a reset_display when the same display is selected (identified by display_name, not display_index) as that will just force a re-init of the existing capture.

I've had some time to test this again (NOTE: it's easily reproducible by spamming CTRL+ALT+SHIFT+F1 hard on the client) and with an attached debugger it hints to a SIGSEGV in the videoThread due to an unmapped address in https://github.com/FFmpeg/FFmpeg/blob/15504610b0dc12c56e5e9f94ff06c873382368f5/libavcodec/hw_base_encode.c#L508

The last Sunshine related call in the call-stack is

Sunshine/src/video.cpp

Lines 321 to 322 in 5364b00

	// Flush any remaining frames in the encoder
	if (avcodec_send_frame(avcodec_ctx.get(), nullptr) == 0) {

It's likely a race-condition but I have no clue if it can be/has to be mitigated in Sunshine or needs to be handled on the ffmpeg side. Maybe someone with a deeper understanding can make use of this somehow.

We could probably add a mechanism to queue the display switching and a small delay before doing it. Then if the user tries to switch 4 times before the delay is over, drop the first 3.

[Kishi85]

That would likely work around most of the possible triggers. I'm unsure if it fixes fully. There's a remark (Line 327) just below above code reference about what actually might to be happening and that it's important to do things in the right order for the hwdevice to be valid (the segfaulting argument causing the crash seemingly being exactly that hwdevice ctx):

Sunshine/src/video.cpp

Lines 321 to 330 in 5364b00

	// Flush any remaining frames in the encoder
	if (avcodec_send_frame(avcodec_ctx.get(), nullptr) == 0) {
	packet_raw_avcodec pkt;
	while (avcodec_receive_packet(avcodec_ctx.get(), pkt.av_packet) == 0);
	}
	// Order matters here because the context relies on the hwdevice still being valid
	avcodec_ctx.reset();
	device.reset();
	}

I'm just guessing but maybe it's just a thread synchronization on device destruction that is missing here.

On a side note: I also think I've managed to hit that specific race condition by accident once or twice during a normal display switch as well but I'm not really sure as that one happens totally random. After that Sunshine crashes cleanly and restarts.
