Changelog for VideoStitch Vahana VR v1.1.0
Monday, August 1, 2016
In this new Vahana VR release, the external audio pipeline and RTMP output features have been re-written from scratch. Moreover, you will have several new ways of capturing input videos (Magewell Pro acquisition cards and network streams) as well as more output options. After YouTube live streaming announcement, Vahana VR now provides a simplified workflow.
Features ======= I can stream to YouTube using Vahana VR UI I can use an external microphone with Vahana VR Improved RTMP output with authentication and server reconnection Support Magewell Pro acquisition cards Support HTC Vive as a preview device Support network stream inputs Support Decklink interlaced inputs Support Decklink card input audio (in SDI and with XLR adapter) Support Akamai CDN Use time-stamps to synchronize audio and video ProRes video compression format support in the HDD output (available with mov container)
Improvements ======= Fit the preview to the screen to improve performances I can use an external microphone named with Unicode characters I want to choose which GPU Vahana VR is using Set accurate default output values (resolution, fps, bitrate mode, key frame, audio configuration...) Displayed time, target fps and stitching fps now based on the same clock (the stitcher's target fps) "Save to HDD" and "RTMP" UIs redesign Acquisition cards in/out UI redesign Add the RTMP connection status to the log Vahana VR stream user agent is now recognizable Vahana VR stability on project open/close Crash reporter comments are analyzed Support Oculus CV1
Bug Fixes ======= Crash when clicking on Snapshot in output tab when audio is enabled and RTMP activated Decklink capture doesn't work when the same card model is used twice Edit the panorama during a live streaming will break the interface and stop the stream The user can change the parameters of an output that is currently used Output settings are not updated when you change the input settings Using inputs of unusual image dimensions leads to a crash Can't reconnect to the RTMP output after a disconnection Vahana VR crash when I close a project with an activated output Interface is broken when you restart one of your two screens Vahana VR crash when you import twice the same template When saving to HDD the output is cut at the end The user can't record 2 videos consecutively with a different video format Downsample/Upsample the RTMP streams breaks it The user can delete an output that is currently used Vahana VR crash when the user choose the pixel format "BGRU" on an output Decklink Crash when you change panorama size Unsupported pixel format (like RGB for Magewell Quad inputs) make Vahana VR crash Time display is cut when project is open for more than 10h Don't create by default RTMP log file as it can fill up the disk (1GB after 16h) Changing RTMP output configuration leads to crash Changing the output file then saving to disk without reloading the project leads to a crash Setting a custom vah.fps results in erroneous framerate Changing display mode in Magewell does not update the stitcher's FPS Masked pixels shouldn't be used Import a PTGui project with crop produces an erroneous FOV Opening videos from HDD as inputs doesn't work just after installing Vahana VR Inputs used in calibration contains the watermark when no license is activated Crash after SDI was disabled or when changing SDI settings Vahana VR will crash when you don't update the Oculus Runtime If I remove my external microphone, I cannot open my configuration Lens type resets to fullframe fisheye after calibration Vahana VR crashes if the input SDI signal doesn't match the one specified in the vah file The Field of View value set in the crop window is not used "Control points" feature is misleading and doesn't bring value GOP parameter is not working as expected
Known issues: =======
NVidia GTX1080 is not supported-> fixed in v1.1.1 Decklink Duo2 and Quad2 are not supported-> fixed in v1.1.2 Memory leak when streaming in CBR mode if the bandwidth is not wide enough-> fixed in v1.1.3 HDD output files have compression issues when using SDI inputs Oculus Rift output instability on disable/close Continuous exposure compensation accumulates ev correction errors Calibration crashes when the Field of View value is set to 0 Stitching time negative on stream inputs Crash when you close Vahana VR during a calibration or the loading of the inputs Cancel update leads to a crash If you unplug the screen on which Vahana VR is running, the app layout is broken
