Short answer: to reverse polar coordinates back to cartesian space, you need to use the HUE correlate as well. Otherwise you won't know the direction the vector is in.

To convert ab to hue:

It means you have dependency conflicts. So try running the following options one by one.

1. Remove node_modules and package-lock.json and then run

I got the code corrected..

As I suggested in a comment

cvlc --sub-source logo --logo-x 10 --logo-y 10 --logo-file ./logo-stackoverflow.png --logo-opacity 100 your.mp4

should display the logo

To activate the crop one pixel from the bottom of the video, for cvlc
either:

set global-key-crop-bottom=Alt+c in the vlc vlcrc configuration file

or:

set it on the command line

cvlc --sub-source logo --logo-x 10 --logo-y 10 --logo-file ./logo-stackoverow.png --logo-opacity 100 --global-key-crop-bottom=Alt+c --global-key-uncrop-bottom=Alt+Shift+c your.mp4

For some weird reason it seems you must set the --global-key rather than just --key

Solved setting maximum bit rate of v4l2 with:

We may draw the text on black background, and use alphamerge for creating transparent background with colored gradient text.
Then we can overlay the gradient (with the transparent background) on the input video.

I don't know if my suggested solution is the most elegant, but it is not lower the brightness of the gradient picture.

The suggested solution applies the following stages:

• Define synthetic black video source (1 frame).
• Draw white text on the black video frame.
• Add the "white text on black background" as alpha channel of the gradient image.
  Only the white text is opaque, and the black background is fully transparent.
• Overlay the above frame over the video.

Start by creating synthetic yellow video file (with sine audio) for testing:

I was able to extract the codec_data by passing the x264enc output into h264parse.

The useParams hook can only access the route match params of a Route within the context of the Routes component rendering it. App is outside the Routes component that renders a route rendering path='/palette/:id'.

You can create a wrapper component to "sip" the id route match param and do the filtering.

Your problem is that decodebin selects nvv4l2decoder that outputs into NVMM memory. videoconvert cannot read from NVMM memory. You would use nvvidconv instead that can read from NVMM and output into system memory.

However, it is not mandatory to decode h264 for reencoding into h264. This simple pipeline should do the job:
