I am using react native and connected to PI camera. It's sending me h.264 encoded string in notification which is direct binary data. and I am trying to display this to video format. So, I am trying to find out how to display this stream as a video. and that string will update in every notification. and I found broadway (https://github.com/mbebenita/Broadway) player. which is for web view only and working perfect with my hardware. So, is there anything like this? which I can use to display h.264 encoded binary data to video using react native.

I am creating an a React Native application which streams video. However, the video source is actually images as it is live and these are sent through STOMP sockets. The image sent are base64 encoded uri. I tried to use Image component but the flickering is bad and there is a lot of delay subsequently in rendering (image uri comes in way faster than the application is rendering). I tried to use libraries such as FastImage and NoFlickerImage but all failed to do the trick. Read up abit about the problem and found out that all of them uses Image component as a base. The problem is probably due to React Native Image component. Any way to get around this issue?
Tried NoFlickerImage, FastImage. Same outcome as Image, flickers and renders too slowly.
I'm working on a traffic detection project, where I get video stream from Youtube livestream using CamGear and then process each frame with OpenCV. I want to display final video with detections in Streamlit app. I tried passing processed frames to st.frame, but for some reason only first few frames are shown and then the video freezes. Now I am looking at using webrtc component, but I can’t figure out, how to change video source from webcam. Thanks.
I am very new to React. I'm trying to build an android application with React Native (Expo) which requires reading a video input from an HDMI to USB converter + an OTG cable.
Video Capture Card or HDMI to USB 2.0 Converter – Live Streaming
I need to :
a) read the input video stream
b) reduce the frame rate of the video to 1fps
c) convert it to grayscale
d) display it.
Can anyone please suggest to me an idea on how to accomplish the above steps?
What is the standard method/process for this job?
Is there any tutorial that I can follow?
react-native-video component
a) can read video stream
b) can change playrate
c) can convert it to grayscale/FilterType.MONOCHROME (only available on
ios devices)
d) can display it.
Here is a brief article about Video Live Streaming with React Native and youtube videos about react-native-video
If possible, recording video directly at 1 fps with grayscale effect can be quite efficient. If this isn't possible, it may be nice to send the final version of the video to the application by performing the operations on the video on the server side. (reducing fps rate and adding grayscale effect on server) Server side operation can cause some delay.
I'm using React Native Camera to record video. I would also like to transcribe the voice at the same time (speech-to-text). I'm looking at React Native Voice but I don't think I can use both libraries at once (sharing the Mic input).
Wondering if anyone has ideas besides uploading the final video file somewhere to get transcribed.
Yes, you can.
You can record video with React Native Camera, and using speech-to-text in Voice Library.
For voice library you can see this or this guides.
I am working on a react-native project which uses Agora.io for video calling.
In a video call it shows my camera feed as fullscreen and the reciever's feed as thumbnail which is the opposite of the correct way.
I want to know, Is this the way agora works or is it possible to fix this..?
Because even in their website they have put the images in that way.

I appreciate any help regarding to fix this.
So it seems like you are presenting the local video stream to the larger view. You would need to switch this. Render the remote video stream on the larger view and the local video stream on the thumbnail view.
