Software Dev / Chronos V0.3.1 Beta - Updated Oct 15 2018 with beta-9
« on: September 27, 2018, 11:39:38 AM »
Update: 0.3.1 has been moved to release candidate, please see this thread for the latest software update.

Hey guys,
EDITED. Please note the changes to Features, Minutiae, and Fixed Bugs.

Here is the V0.3.1 beta-9. Remember, do not use this software version if you are capturing something that is not easily replicated. Here are the notes on the update:
  ++                                          ++
    |   Chronos V0.3.1.9 Changelog   |
  ++                                          ++

Notable Changes:
 - New Demosaic algorithm based on AHD, which should improve color reproduction and reduce edge noise.
 - Standalone daemon to operate the video system, with DBus API.
 - External HDMI displays are supported at 1080p and 720p resolutions.
 - Recording speed improvements.
 - Add CinemaDNG and TIFF as save file formats.
 - Deprecate Raw 16-bit right-justified save format in favor of CinemaDNG.
 - Add a demo mode to replay a section of recorded video in a loop.
 - Add option to overlay frame statistics onto processed video formats (H.264 and TIFF).
 - Jog wheel can be used to adjust the exposure, and navigate the settings menus.
 - New video memory recovery tool to download video (slowly) in the event of a software crash.
- Redesign of the white balance window, including a new dialog to edit the color matrix.

 - Add whitebalance preset for 3200K/Tungsten lighting.
 - Adjust highlighting of text when selecting text boxes.
 - Auto-record and auto-save modes independant of one another.
 - Improved algorithm to estimate framerate during file save.
 - Date format in the Utility window changed to shorten the Month string.
 - Display separate version strings for both the Application and Filesystem/Release.

Fixed Bugs:
 - Crash causing the video to freeze after approximately 45 recording attempts.
 - Trigger delays would scale incorrectly when using segmented recording mode.
 - Abort recordings when the free space drops below 20MB to avoid crashing when the disk is full.
 - UI bug causing the selected save location to always select the first mounted disk.
 - First frame of a raw recording would contain corrupted NV12 image data.
 - First pixel of a Raw 12-bit packed frame was sometimes being dropped.
 - Corrupted pixels at the end of a Raw 12-bit packed frame.
  - Add crosshairs to the white balance window.
  - Add Qt stylesheet to improve focus visibility.
  - Main window exposure now shown in microseconds and shutter angle.
  - Jog wheel now adjusts exposure logarithmically, or by degrees when pressed.
  - The 'close' button on the soft keyboard now applies the entered text.
  - Reorganization of the soft keyboard to include a negative key.
 - Black ares of the UI become transparent after an HDMI hotplug.
  - HDMI hotplug while on the playback window would revert to live display.
  - Add missing ColorMatrix1 and CalibrationIlluminant1 tags to CinemaDNG files.
  - Fix possible crash of the video system when aborting a file save.
  - Fix possible carsh of the UI when rapidly aborting and re-starting a file save.
  - Fix color correction math so that saturating the image sensor tends towards white.
Also, some bugs that were introduced in beta-4 but now fixed:
  - Monochrome TIFF now pads the pixel values with least-significant zeroes.
  - H.264 bitrate setting was being ignored and defaulting to 0.25 bpp.

Compatibility Issues:
 - The pixel packing order in Raw 12-bit mode has been changed for the v0.3.1 release.
   Given a pair of two 12-bit pixels in hexidecmal as (0x123, 0xabc), the bytes produced
   by the Raw 12-bit packing mode changes as follows:
     v0.3.0 and earlier: (0xab, 0xc1, 0x23)
     v0.3.1 and later: (0x23, 0x1c, 0xab)

Known Bugs:
 - The first frame of an H.264 recording is erroneously copied from the display buffer before the recording starts.

Chronos User Discussion / Re: Connect to Chronos 1.4 via Ethernet

Hey there,
If you check out the Software Dev section, there is a post about our software road-map that has details about the progression of the software for the Chronos. Ethernet is on the way as well as the API in the fall.
I know that scp has been used with some of the dev cameras here at Kron Tech. But I am not sure if the software guys were using it on the Debian testing software or if they did get it working with Arago (0.3.0).

Hiya there,
We have had NTP working with Debian, not the current Arago. So in the next few months it could be possible. For now, I will see if our software engineers have a work around.

If you guys have noticed, DDR has posted in the Software Dev section a road-map for the next three months for the Chronos 1.4. I suggest taking a peek.
It looks like HDMI is getting really close and we could see it by the end of August as part of the 0.3.1 release. It should be going into alpha soon (closed with experienced users) and then, beta (usually posted in Software Dev) will be released in the week or two prior to release. Keep your eyes peeled on the Software Dev discussion area for more updates.

I believe our software team is working on making one available. I can ask at our next stand up meeting if that is something that is in the works.

Hey guys,
HDMI is on the way. We have it in the road map for the next update. For more information check out the News Blog on the website.
