v4l2Camera – Open Source Project updated

Building on the code base and functionality already in place in the open source package v4l2Camera (git hub repository here) we are pleased to announce a new release (1.4.80) containing a good deal of new features!

New features :

• full support for frame rate selection for each supported video mode
• multi-buffer support for low level data fetches improves latency and maximized frame rate
• improved display and log message display
• image output format options (save as JPG, PNG or BMP) across all image formats supported by UVC cameras (MJPEG, YUV, YUV, Grayscale)
• video capture to AVI/JPG with no encoding overhead
• camera bench marking function (-T) to verify maximum frame rate supported by UVC cameras
• full camera control support (exposure, brightness etc)
• better, folder based makefile

We have added a few MP4 utilities to increase access to H264 frame formats supported by newer cameras :

• added header support (-H) to append a size and content header to each H264 frame to facilitate encoding into other video formats
• wrapMP4 utility added to take H264 frame and create a minimal, compatible MP4 wrapper for the H264 frames. Displays correctly in VLC.
• walkMP4, a dictionary based utility to display MP4 headers to verify MP4/MOV/QT file format compliance
