Msp Osd Versions Save

• Fixed 2nd font page being blank for Betaflight 4.5 and generic FC configurations, now falls back to page 1.

This version fixes rebooting issues related to thread safety issues with dji_duml_hal by changing framebuffer usage.

This release is mainly to help new users:

• compress_osd as well as the goggles-side recording options are now enabled by default for new installations only. For existing installations which are upgraded, you will still need to adjust your settings using the CLI.
• A small fix to goggles-side OSD overlay playback when using FakeHD which will prevent FakeHD from being applied twice (thanks, Knifa!)

Fix the playback feature from https://github.com/fpv-wtf/msp-osd/releases/tag/v0.9.0 so it works on V1 goggles.

No air unit changes, so you don't need to install the new Air Unit version if you don't want. Also no changes for V2 users.

Adds rec_pb_enabled configuration option.

If this option is set to TRUE, then recorded OSD data (from rec_enabled) will be played back in the goggles using the builtin playback functionality.

No air unit upgrade is required, just along for the ride.

Thanks @Knifa

This enables "True HD" mode in Betaflight, without the use of FakeHD.

Note that True HD mode in Betaflight requires a Betaflight 4.4 and Configurator build from after December 4, 2022.

True HD will be enabled by default in Betaflight 4.4. Simply connect your AU/Vista to the FC and pick MSP VTx + DisplayPort as the Ports type. You may also need to manually use set osd_displayport_device = MSP in the Betaflight CLI still.

You should see your Configurator switch into "HD" mode where you can drag elements wherever you would wish on a full 60x22 canvas, going all the way out to every edge of the display.

FakeHD will automatically disable.

If you don't want to use True HD mode in Betaflight 4.4, because you want FakeHD still for some reason or you prefer the larger, old font, set disable_betaflight_hd on the wtfos VTx side.

While there is a new Goggles version included, it's only for consistency and contains only code efficiency / formatting changes. Everything should be fully cross compatible and you only need to upgrade the Vista/AUs which you wish to use with Betaflight 4.4 HD mode.

Goggles only.

Fixes fakehd when used with the new compressed transmission.

Fixes an issue with recording the OSD to SD while the new compressed mode is enabled.

No new airside, 0.7.0 remains the latest airside.

LZ4 Compression (#79)

Add a new configuration option, "compress_osd", to the air side process.

If this is set to "true", then the entire "character buffer" will be sent using LZ4 compression at the rate defined in osd_update_rate_hz, instead of sending raw MSP messages over the air.

When enabled, this should fix INAV delta update related issues as well as provide better link stability.

To enable:

Use the CLI button in the configurator on your VTx side after updating to 0.7.0.

package-config set msp-osd compress_osd true
package-config apply msp-osd

If the apply hangs, just reboot your VTx.

Note that INAV HD mode sync issues may still be present, use the usual workarounds (enter menu or switch screens) to fix these.

Compressed mode may also be valuable for other FCs, as it should make the overall link much more reliable and stable.

The goggles side is backwards compatible, so you can continue to use un-updated VTx, they just won't get the new feature.
