Add MPV to Multimedia Tools as a Video Player

[TheMysteriousMirageofOld]

Hi, MPV is one of my favorite video players and it's very easy to modify and do with as your wish, but it's not available in the Multimedia Tools list like MPC-HC and VLC. Could it be added?

Answer: Raspberry Pi Mining on RustChain

Great questions! Let me break down the Raspberry Pi situation:

1. Is Raspberry Pi considered Modern ARM?

Yes, unfortunately. The Pi 4's Cortex-A72 is classified as Modern ARM because:

• It's a 64-bit ARMv8-A architecture (not ARMv5/ARMv6 vintage)
• It doesn't qualify as vintage by RustChain's definition (pre-2005 hardware)
• The Pi 4 was released in 2019, so it's only ~7 years old

The ARM SBC bonus (+1 RTC) applies to the hardware itself, not the multiplier. So while you'd earn at the base 0.0005x rate, you'd get +1 RTC bonus per epoch for running on an ARM SBC.

2. Would it be worth running?

Honest answer: Not for profit, but yes for participation.

At 0.0005x multiplier, a Pi 4 would earn roughly:

• ~0.0001 RTC per epoch (vs ~0.5 RTC for a G4)
• That's ~0.0014 RTC per day (16 epochs/day)
• At $0.10/RTC = $0.00014/day (~0.014 cents)

However, the +1 RTC ARM SBC bonus per epoch means:

• ~0.016 RTC/day from bonuses alone
• ~$0.0016/day (~0.16 cents)

Still small, but:

• Pi 4 costs ~$35-50
• Power consumption: ~5W = ~0.12 kWh/day
• At $0.15/kWh = $0.018/day electricity
• Net: -$0.017/day (you lose money)

BUT: If you already have Pis lying around (free hardware), then:

• Pure profit: $0.0016/day per Pi
• Break-even: ~22 years (lol)
• Value: Participation in the network, learning, supporting vintage hardware mission

3. Anti-emulation checks on Pi

The Pi should pass all 6 fingerprint checks normally:

• Clock drift: Real silicon, passes
• Cache timing: Real ARM cache, passes
• SIMD identity: NEON extensions present and real, passes
• Thermal drift: Real thermal behavior, passes
• Instruction jitter: Real CPU timing, passes
• Anti-emulation: Not running in emulator, passes

Run python3 fingerprint_checks.py standalone first to confirm. I've seen Pis pass without issues.

4. Multiple Pis

Yes, you can run miners on all 5 Pis! Each Pi has:

• Unique MAC address
• Unique CPU serial number
• Unique hardware fingerprint
• Unique miner ID

The system treats each as a separate miner. This is actually a great use case for RustChain — distributed edge computing with multiple low-power devices.

Pro tip: Set up a coordinator script that manages all 5 miners and aggregates the rewards. Each Pi gets its own wallet name (e.g., pi-1, pi-2, etc.), but you control all of them.

Bottom Line

For profit: No, not with current rates.
For participation: Yes, absolutely!

RustChain's mission is about:

1. Preserving vintage hardware (you're supporting this by running on Pi)
2. Decentralized mining (multiple devices = more decentralization)
3. Learning the technology (great for understanding PoA)
4. Network security (every miner helps)

If you have spare Pis, run them! Even if you lose a few cents per day on electricity, you're contributing to a unique blockchain experiment that rewards old hardware. That's worth something.
