I know I need to convert to an RGB or YUV image and then pass to nvvidconv but the following pipeline gives me negotiation errors: gst-launch-1.0 -v v4l2src device='/dev/video0' ! video/x-raw,format=GRAY16_LE, width=848, height=480 ! videoconvert ! video/x-raw,format=RGBA, width=848, height=480 ! nvvidconv ! 'video/x-raw(memory:NVMM),format=NV12' ! nvv4l2h264enc maxperf-enable=1 insert-sps-pps=1 idrinterval=1 ! h264parse ! queue ! rtph264pay ! udpsink port=5000 host=192.168.12.187 sync=false

Working in a 16-bit color space right up to when you save a JPG minimizes the chance of banding in the final image.How do I convert the following pipeline: gst-launch-1.0 -v v4l2src device='/dev/video2' ! queue ! nvvidconv ! 'video/x-raw(memory:NVMM),format=NV12' ! nvv4l2h264enc maxperf-enable=1 insert-sps-pps=1 idrinterval=1 ! h264parse ! queue ! rtph264pay ! udpsink port=5000 host=192.168.12.187 sync=false Use the File/Save for Web command to save the image as a JPG since it automatically converts the image into an 8-bit sRGB JPEG image and saves the file with the correct color space information embedded in it.

If you don't do this then working color space (ProPhoto in my case but this also applies if you use aRGB) information is embedded in the file and the image colors will not be correct.Ģ. Use the Edit/Convert Profile/sRGB before using the File/Save As/JPEG command so that sRGB color space information is embedded in the 8-bit JPEG file. If saving from Photoshop as a JPEG then I do one of two things.:ġ. I normally save 8-bit sRGB JPGs directly from Lightroom since it automatically converts the file format and embeds the correct sRGB color space information in the image file. Saving JPGs is a separate process from saving TIFFs. If I want to do further edits to a TIFF I can open it from Lightroom with all layers intact by opening the original file or I can start with a flattened version by opening a new copy. I save all TIFF images with all layers intact and all TIFFs are returned to Lightroom to make keeping track of them easy. I never modify the background layer and do non-destructive editing as much as possible.ī&H - Tim Grey - Photoshop CS6 for the Photographer - YouTube In Photoshop work in 16-bit TIFF since ACR and Lightroom export images to Photoshop in that format.

Work in 16-bit ProPhoto so that the color spaces in Lightroom (almost ProPhoto), Adobe Camera Raw, and Photoshop all match.
