1. Virtual Reality (VR) capture

To stay up to date with modern technologies I decided to implement a possibility to capture VR videos.
Here are some examples (watch in your VR headset):

Reveal hidden contents

Long story short: this is achieved by capturing cubemaps in the game and then passing them to ffmpeg (pipe) with v360 filter.

To capture a VR video yourself set mme_saveCubemap to 1 and mme_pipeCommand to auto.

Long story long:

Reveal hidden contents

The idea:
jaMME is a pretty complete tool and making new releases requires some big features. Also staying up to date to modern technologies is a good reason for a new release as well.
The idea visited me a year ago when I got my VR set. So here we are: I decided to add the VR capture into jaMME.

The solution:
After googling a lot I found many solutions but all of them could not be simply applied to the game.
Eventually I got the main idea: I need to capture the whole world around and the simplest way to do so it to capture cubemaps.
And then I accidentally found out that ffmpeg can convert from and to any kind of spherical projection and that I could just use cubemaps.
A year later all stars got aligned.

VR video types:
1) 180 degrees stereoscopic 3D (VR180)
2) 360 degrees monoscopic (VR360)

To capture for VR:
1) highly recommended but still optional: install ffmpeg and either put ffmpeg.exe next to jamme.exe or add it to %PATH% variable
2) set resolution to at least 720 pixels height (for example: set r_customwidth 1280; set r_customheight 720; r_mode -1)
3) set cg_draw2D 0; set con_notifytime -1; mme_saveCubemap 1
4) VR180:
set r_stereoSeparation -0.5; set r_zproj 25
set mme_pipeCommand "ffmpeg -f avi -i - -threads 0 -vf v360=c1x6:he:in_forder=frblud:in_stereo=tb:out_stereo=sbs -c:a aac -c:v libx264 -preset ultrafast -pix_fmt yuv420p -crf 19 -y -metadata:s:v stereo_mode=left_right %o.mkv 2> ffmpeglog.txt"
eyes are separated by 0.5 game units from the centre (-0.5 is the same, just for the left eye) and the focus point is 25 units forward, values can be changed
using filter v360 we set input projection as cubemap 1x6 with faces order 'forward right back left up down', output projection as half equirectangular and input stereo top-down, output stereo side-by-side
VR360:
set r_stereoSeparation 0
set mme_pipeCommand "ffmpeg -f avi -i - -threads 0 -vf v360=c1x6:e:in_forder=frblud -c:a aac -c:v libx264 -preset ultrafast -pix_fmt yuv420p -crf 19 -y %o.mkv 2> ffmpeglog.txt"
using filter v360 we set input projection as cubemap 1x6 with faces order 'forward right back left up down', output projection as equirectangular
to capture for YouTube container should be mp4, in other case set it to mkv
more info: https://ffmpeg.org/ffmpeg-filters.html#v360
5) capture pipe 60 name
That's all, the video is captured.

Editing:
You can edit your VR video in Adobe Premiere Pro: https://helpx.adobe.com/premiere-pro/using/VRSupport.html
And publish from there as well so the Publication block could be skipped.

Publication:
To make video players understand that the video is VR (uploading to YouTube requires that too) it has to have the corresponding metadata.
Unfortunately by the date of 2021.11.24 ffmpeg cannot add such kind of metadata so you have to use other tools.
You can inject additional metadata by using mkvmerge tool:
VR180 for manual sharing and YouTube:
mkvmerge --output out.mkv --projection-type 0:1 --projection-private 0:0x000000000x000000000x000000000x3fffffff0x3fffffff --stereo-mode 0:side_by_side_left_first in.mkv
VR360 for manual sharing:
mkvmerge --output out.mkv --projection-type 0:1 --projection-private 0:0x000000000x000000000x000000000x3fffffff0x3fffffff in.mkv
Or you can use Header editor from MKVToolNix GUI to add projection type, projection type private data (or leave it untouched) and stereo mode in case of VR180. Setting stereo mode is not needed if it was set though ffmpeg.
more info: https://mkvtoolnix.download/doc/mkvmerge.html
https://github.com/google/spatial-media/blob/master/docs/spherical-video-v2-rfc.md#webm-matroska
VR360 for YouTube:
You can inject additional metadata by using Spatial Media Metadata Injector:
0) convert to mp4 if previously captured in mkv:
ffmpeg -i in.mkv -c copy out.mp4
1) download: https://github.com/google/spatial-media/releases/tag/v2.1
2) run the tool and check "My video is spherical (360)"
3) click "Inject metadata" and wait a bit
The video is ready for YouTube.

Video resolution:
The least recommended resolution of the game should be WIDTHx720, so it could capture cubemaps with 6 faces of 720x720 and final video resolution will be 2880x1440.
2880x1440 is one of the most popular resolution for many VR sets.

Extra:
Technically VR360 could be stereoscopic 3D but looking behind will swap eyes position so the depth will be ******ed up. Though you can look up and down by way higher angles.
So VR180 could be monoscopic as well but it has no sense since VR360 monoscopic covers everything.
You can capture for VR without pipe, just save cubemaps directly into screenshots or AVI. But then you will need to convert the cubemaps into any spherical projection anyways. Pipe is the default way now so better use it.
YouTube compresses much so it's better to capture at high resolution like WIDTHx1080.

2. Multispec feature

Multispec feature lets you see multiple POVs simultaneously.

Reveal hidden contents

Using the feature is pretty simple. Hit = (command: multispec add) to add a new multispec window. It will appear in the centre of the screen with a cursor that you can move and edit multispec windows.
Put the cursor inside the window and click MOUSE1 or MOUSE2 to cycle through next or previous POV. Camera and Chase POVs are also options.

Holding MOUSE1 and moving mouse will move the window. Scrolling mouse wheel will change window scale. Hitting DEL will delete the window. Hitting ESC or ENTER will finish editing.

That's all, you got your multispec window. You can add as many windows as you want. More information and examples in the documentation.

3. Scripting console commands

Script is a another keypoint-based mode that lets you execute console commands in certain moments in the demo.

A few steps to use the feature:
1. Pause the demo.
2. Hit 5 to enter into script editing mode.
3. Hit V to add a keypoint.
4. Hit MOUSE3 to activate the editable demo HUD.
5. Select Run: and type some command, for example: "clientOverride player model reelo".
6. Move in time a bit. Repeat steps 2-4 but 4 with run: "clientOverride player model tusken".
7. Move back to the movement before the first keypoint.
8. Unpause the demo.
9. See how commands get executed in the exact moments they have been set to.

Additionally you can edit Init: value in step 5.
Init commands are guaranteed to be executed for all keypoints before current time when you rewind. Basically is used as a "reset" command.

4. Bookmarking demo time

Sometimes you'd like to edit some moment in the demo but later since now you are editing another part so you can save that moment with bookmarks!

Simple to use: hit 6 then hit V and it's added. Hit Q or E to jump between them.

5. Notifications

You now get notified about demo event when your game is minimized/unfocused. Notifications could be textual, flashing and console. Basically they look like this:

You can be notified about capture start, capture end and find command results.

6. Custom "bokeh" in DOF (credits: Tom Arrow)

Now you can set a DOF mask that can basically be treated as custom "camera lenses" that create custom blurring shapes in DOF. Just use any grayscale image with cvar mme_dofMask, for example: mme_dofMask gfx/2d/dlight to use dynamic light circle as a dof mask.
