[Issue]: Moonlight cannot find hardware accelerated video codecs

Describe the bug

About a month ago I stopped being able to use Moonlight on my Poco X3 Pro running crDroid 11.2 (Android 15). The issue I get is a black screen with a popup that says "This device or ROM doesn't support hardware accelerated H.264 playback.". It used to work just fine before.

I recently noticed an update for my ROM that happened around the time when I started having this issue that says "Removed deprecated OMX and replaced with c2 media codecs". Checking the Moonlight logs I notice a peculiar line that says "Examining decoder capabilities of c2.android.avc.decoder (round 1)" and then "Skipping software-only decoder: c2.android.avc.decoder", so I was wondering if it's possible that Moonlight thinks this decoder is software-only when it's actually a usable hardware codec on my device.

I've already checked the basic troubleshooting guide to no avail, and I've recently asked for help on the Discord server, but nobody was able to figure out what was going on.

Steps to reproduce

• Run Moonlight on a Poco X3 Pro running the latest crDroid 11.2 ROM
• Pair a device running Sunshine
• Try to connect to the device

Additional context

No response

Start by tracing the Android decoder capability check that emits the reported c2.android.avc.decoder and FEATURE_LowLatency log messages. Compare how the c2 and OMX codecs are classified on the affected device; done means AVC hardware acceleration is correctly recognized and the connection no longer reports that no AVC decoder was found.
