stitchem's Introduction

Vahana VR & VideoStitch Studio: software to create immersive 360° VR video, live and in post-production.

The software was originally developed by VideoStitch SAS. After the company folded in early 2018, the source code was acquired by the newly founded non-profit organization stitchEm, to publish it under a free software license.

Vahana VR

Vahana VR is a camera-rig independent real-time 360° VR video stitching software.

With Vahana VR you can capture multiple video streams, stitch them instantly into a single 360°×180° video file, preview the result in real-time and stream it to any 360° video player or compatible platform.

Vahana VR supports range of video capture and output hardware, including Decklink SDI cards from BlackMagic Design, and HDMI capture cards from Magewell, Ximea cameras and RTMP network broadcasting.

VideoStitch Studio

VideoStitch Studio is a post-production video stitching software that enables you to create immersive 360° VR videos. It takes video files and stitches them into a standard 360° video file automatically.

VideoStitch Studio supports input synchronization, automatic calibration, exposure and color correction, video stabilisation and a range of different output formats.

Orah 4i

The Orah 4i is a camera with 4 fisheye lenses designed for live 4K 360° Video streaming. Information on setting up the camera is found in a the dedicated camorah respository.

Usage & Community

The VideoStitch Studio User Guide describes the stitching workflow using the software in detail.

If you need help getting started, have an idea for improvements or want to help develop the software, come join the VideoStitch Studio Users group on Facebook.

Technical issues can be directly reported on GitHub.

Download

Builds of Vahana VR and VideoStitch Studio for Windows and macOS can be downloaded in the release section.

stitchem's Issues

igfx_s3dcontrol.h not found error.

When windows build project, It happen 'igfx_s3dcontrol.h not found error'.

I think it is Intel media SDK version issue.

Is it OK? what version to use??

Vahana and Orah 4i

how can I connect to Vahana directly by Orah 4i camera, and its four H264 streams grab directly through RJ45? it's the same ex company, isn't it in the source code?

Distinguish between no compatible GPU found and no GPU backend built

The device detection defaults to FrameworkStatus::NoCompatibleDevice if the backend is not built, both for CUDA and OpenCL.

As both Framework Statuses are now the same, Vahana VR will default to CUDA and then print an error that no CUDA compatible device was found.

This doesn't make any sense in cases where only OpenCL support was built, and no CUDA support was built. The framework status of not-having-the-backend should have a higher error code than no-device, and the app should finally show a message about no OpenCL device being found.

cropInputTest fails on Travis/Linux

Not sure if the X display error is related - all the Qt tests are passing. It's passing on Travis/Mac as well.

Failed to initialize NVML: Unknown Error is also expected with no GPU present I think, without being the reason to fail the test.

Vahana VR cancel button is a broom

Cancel button should be a cross instead. See log window. You've got the broom in the bottom right to clean the output. And you got the broom again on the top right to close the window.

DirUtilsTest tests the cache directory infra for OpenCL kernel caching. Needs an update to the dockerfile to be allowed to write to /root/.local/share/VideoStitch?

Speed up homebrew install on Travis/Mac

Travis Mac builder spends ~13 of 19 minutes build time (see e.g. https://travis-ci.org/stitchEm/stitchEm/builds/526026548) on downloading homebrew, updating homebrew and installing the deps.

I tried adding the HomeBrew cache directory to the osx matrix: https://github.com/stitchEm/stitchEm/tree/w-m/brew-cache

Output in the build:

adding /Users/travis/Library/Caches/Homebrew to cache
Homebrew is not yet cached
...
==> `brew cleanup` has not been run in 30 days, running now...

Doesn't seem to work - shouldn't brew cleanup have been run before_cache?

Is it legal to put the cache line inside the matrix/include in Travis, does it get added to the global cache: ccache?

sample videos dataset

can anyone provide some sample videos datasets？I don't have the equipment to get videos that can stitch together。

Crash when importing files with mono audio

When creating a new project or dragging video files and dropping them into the drop pane causes the app to crash. I'm using 2 video files in an attempt to create a 180 equilatriangular video. If I select only 1 of the 2 videos in the New Project flow it imports than I can use the File -> Open Media to add the other video.

However I have a 2nd set of videos that I have tried this same workaround but it doesn't work, I have to import the same video from my first set and then I can Open Media to add the videos from the 2nd set. The issue with this is now I have 3 videos and there doesn't appear to be a way to remove the video from the 1st set.

I've attached a screenshot to show what I mean, the 1st video is from the 1st set and the only way I'm able to import is the other 2 is if I 1st import the 1st one when a new project is created and then I use the Open Media menu to add the other 2 but I don't see a way to remove the 1st one.

Building from source on macOS

Hi all,
Sorry in advance for this but I can't build this.
I was a VideoStitch studio customer and I'm just trying to pick up where I left off as a stitcher not a coder. I've installed the GUI version of CMAKE and tried to compile there but get errors building.

CMake Error at /Applications/CMake.app/Contents/share/cmake-3.15/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  Could NOT find PNG (missing: PNG_LIBRARY) (found version "1.4.12")

I appreciate there are numerous external dependencies but is there any prospect of this being packaged up for folk like me?

Many thanks and sorry for the low level skills issues!

Vahana VR HDD output setting broken

Open Vahana VR 2.4.0, create a new project, add 4 test inputs (default), add HDD output with default settings (hdd_export.vah.zip).

Enable HDD output and watch the log, these lines are continuously repeated:

[2020/05/03 13:04:33] [libavoutput] failed to re-instanciate LibavWriter implementation.
[2020/05/03 13:04:33] [libavoutput] LibavWriter : no implementation is instanciated

No output file is created.

Streaming capture video display error

Did you Khow why this error happend?
( I use two magwell pro capture board & 6 gopro cameras )

Create Mac Studio app package

adapt make_dmg_functions.sh to work with MacPorts binaries (rpath?)
adapt make_dmg_functions.sh to work with HomeBrew binaries (rpath?)
disable codesign (stitchEm is not eligible for to get the membership fees of the Apple Developer Program waived)
create library license page
create menu / help entry linking to license page
create release on GitHub, upload .dmg
automatically push .dmg to GitHub from Travis?

VR180 stereo

Hi, first of all. Great project! Thanks so much for making it open source.
I want to use vahana for live previewing VR180 3D videos.
I have two cameras facing the same direction. get a pair of circular fisheye images. Instead of stitching them I want to make stereo 180° x 180° video and live preview it in oculus rift. Is vahana ok for this?

Support OpenCV 4 on macOS with MacPorts

The OpenCV 4.1.1 that comes pre-installed on the Jetson Nano does not have the old CV_XYZ constants anymore, see #59. Checking with findContours, they were used in OpenCV 2.4, but from OpenCV 3.0 they changed to the namespaced cv::XYZ.

TODO:

have a builder with OpenCV 4
change constants to namespaced versions
require minimum OpenCV 3 in CMake
support with the macOS MacPorts build

Version string in about window shows additional dash

Studio 2.4.0 on Mac:

WIN10 installation?

Hi! I found the link to stitchEm in FB group of 360° videographers, but no one know how to compile it and make running on WIN10. Any hint? Thank you in advance

CUDA API Error

I try to show input Sources in Vahana VR.
Error occur and screen is black.

Here is error code. I had already install CUDA10.0.

stitchingWindowTest is failing on Travis

The problem is probably that the VMs used don't have a stitching compatible GPU. It's a situation in which any of the apps would refuse to launch anyways. But this UI test shouldn't depend on the build hardware.

Original VideoStitch Software

Hello! I know this is a long shot, but thought I'd ask since it seems the Windows version of this isn't ready yet.
A few years back I purchased a license for VideoStitch Studio V2. Earlier this year I had to reformat my harddrive, and when I went to reinstall the software the license no longer validated and that's when I learned the company had gone under.
Does anyone know of a way to get my validation code working again? (I still have the original purchase email if needed for verification purposes)
I just shot a 360 interview a few days ago, and if I can get this working again, it will save me a TON of time.

Mac cmake errors

I bypassed the openAl in the install script and have everything else installed. However, when I attempt to do the cmake command I'm getting an error.

Automatically build & install Windows deps

Windows doesn't have a system-wide package manager for the installation of the library/build dependencies. At VideoStitch, the required packages were manually built and distributed as binaries, a process which we can't replicate for the open source project.

This ticket tracks the progress of automatically installing the required deps on a Windows 10 environment.

The ultimate goal is to have an automatic Windows build. Perhaps on AppVeyor?

ccache cache caching

Title says it all?

Travis CI could be sped up by keeping the ccache around between builds: https://docs.travis-ci.com/user/caching/#ccache-cache

Probably needs a little work than this single line to pass it through to the Docker container, but that seems straightforward as well: https://stackoverflow.com/a/39652117/463796

opanAL on MacOS

I'm running into an issue which appears to be installing openAL on MacOS 10.14.6 (Mojave). When I go through the stitchEm install scripts it's failing on openAL.

sudo port install opencv glew gsed jpeg libpng openal tiff faac faad2 ceres-solver glfw ffmpeg glm OpenEXR

Error: Follow https://guide.macports.org/#project.tickets to report a bug.
Error: Processing of port openal failed
Which of course causes issues when I try to cmake.

Looking at main.log as indicated in the terminal error the bit that seems the most relevant is the 404 error:
:debug:archivefetch Fetching archive failed: The requested URL returned error: 404 Not Found
:msg:archivefetch ---> Attempting to fetch openal-1.3_0.darwin_18.x86_64.tbz2 from http://aus.us.packages.macports.org/macports/packages/openal

I'm not familiar enough with where I should be going to get openAL when it fails with macports. I've seen some mention that it's already installed on macOS and I can't find the developer section at creative that appeared to have downloads and openAL.org the SDK download is an .exe

I think Steve in issue #27 ran into the same exact thing I've been facing but I'm not sure how he got openAL installed to finish the cmake.

Any suggestions?

Compilation in macos with backend OPENCL asks for CUDA

Hello, I want to compile the project for mac using backend OPENCL.
I used macports to install the dependencies and compiled it with GPU_BACKEND_CUDA=OFF, GPU_BACKEND_OPENCL=ON, and GPU_BACKEND_DEFAULT=OPENCL using cmake-gui.
It compiles with no errors but when I try to run videostitch-gui I get the message "Your CUDA driver appears to be outdated" and then it closes, the same happens with vahana vr.

Windows 10 CUDA illegal address

When building a release build in Windows 10 with Visual Studio 2017, there are CUDA illegal address errors at runtime.

The errors have been reproduced on @jeremad's machine (GPU: ?) and on @w-m's machine (GTX 980 Ti). Latest graphics drivers are used.

The errors appear when building with CUDA 10.0 and with 10.2.

CUDA 9.2 can't be used, as it is not compatible with the latest Visual Studio 2017 compiler.

Stitching is fine when running a debug build with the same configuration, on the same machine.

The first error that is thrown (uncomment https://github.com/stitchEm/stitchEm/blob/master/lib/src/cuda/error.cpp#L20 and look at the log, not the first error dialog) seems to always be cudaEventSynchronize:

deviceEvent.cpp (24)
deviceStream.cpp (90)

The following CUDA error locations are somewhat random and can be disregarded I think, as the illegal address thing seems to be unrecoverable and is not purged after it's thrown.

Error is thrown both in Studio and Vahana VR.

Has anyone 'GoPro Hero4 6 Rig preset data'?

Is it diffrent gopro hero3 preset data(360Heroes - H3Pro6L v2.preset)??

Provide automatic builds

It would be great to provide automatic build, for example using GitHub actions.

How to fix code in libvideostitch-gui library?

Studio shouldn't allow export of resolution > 4K with h264 codec

When exporting a project with h264 and a horizontal resolution > 4096px, the output silently fails (there are errors of libav in the log). See discussion in #27 and #53.

The UI should warn about this combination of configurations, and suggest a different codec.

Jetson Nano cmake Error

I'm attempting to get StitchEm Studio running on a Nvidia Jetson Nano. I'm running into it complaining that several variables are used in the project but they are not set:

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
FFMPEG_avcodec
linked by target "avPlugin" in directory /home/aspen/Documents/Development/stitchEm/IO/src/av
FFMPEG_avformat
linked by target "avPlugin" in directory /home/aspen/Documents/Development/stitchEm/IO/src/av
FFMPEG_avutil
linked by target "avPlugin" in directory /home/aspen/Documents/Development/stitchEm/IO/src/av
TIFF
linked by target "tiffPlugin" in directory /home/aspen/Documents/Development/stitchEm/IO/src/tiff

I've tried a couple different cmake with -DISABLE_AV=ON and with -DISABLE_TIFF=ON
cmake -DGPU_BACKEND_CUDA=ON -DGPU_BACKEND_OPENCL=OFF -DISABLE_AV=ON -DDISABLE_RTMP=ON DISABLE_TIFF=ON -G Ninja stitchEm

cmake -DGPU_BACKEND_CUDA=ON -DGPU_BACKEND_OPENCL=OFF -DDISABLE_RTMP=ON -G Ninja stitchEm

Any suggestions on how to get past this?

Support Homebrew env for macOS build

Travis CI is using Homebrew in their macOS environments: https://docs.travis-ci.com/user/reference/osx/

Our CMake files currently only deal with a MacPorts environment. Shouldn't be too much work to also support homebrew, but I need to figure out how to test both on the same dev machine.

OpenCL as default GPU backend on Mac

Since Mac is dropping support for Nvidia by default it should be set to compile for OpenCL.

I have 2 cameras one pointing to the left and another over the top of the nodal point pointing right. I stitch them together but the resulting video there is a lot of black around it. I then take it into Premiere to crop it down. Ideally I'd like to know how to set up my panorama so I don't have to take this step.

My source footage is 3840 × 2160. The stitchEm output is 4096 × 2048. Here's an example of what a frame looks like, I'd like to make it so there is no black.

Thanks,

Mike

Disabling SPIR fixes these compiler errors.

--> Disable SPIR by default when creating apps?

Remove readdir_r

readdir_r is deprecated, let's use the thread-unsafe readdir.
