I'm a beginner trying to understand GStreamer yet, but a little boilerplate on using GStreamer for rtspsrc to aiortc python module for WebRTC would be quite helpful as I couldn't find any good example.

Greetings!! I am developing an app with React Native. Which uses chroma key functionality for live streaming or video recording. I failed to find any ready library or plugin. As well as could not find any ready code to help me.
If you have any suggestion for it then do let me know. It would be a great help
Regards
If you want to use the live streaming function, you can use WebRTC technology.
The appropriate react-native library address is as follows.
react-native-webrtc
I am working on an action-camera like device. I need to implement the functionality to play recorded videos. Namely, the playback ui should be able to play/pause, seek, 2x speed playback and display time/duration of the AVI file. SDL 1 is used for the graphics and Buildroot for building.
I like libvlc, but for some reason it is really slow on the target system.
To write my own video playback ffplay as a foundation is the viable alternative. I find it to be low-level compared to libvlc though.
Could you please suggest me libraries like libvlc that are promising for video playback implementation in embedded Linux?
I'd look at the gstreamer framework, if it has support for hardware acceleration on the target.
I am making an Android app in Unreal Engine4.
I want to apply Agora to the Android app.
https://docs.agora.io/en/Interactive%20Broadcast/start_live_android?platform=Android
I applied Agora in the way it is here.
However, if you use createAgoraRtcEngine, it will not build.
I don't know why the compiler can't find the implementation of the function.
Agora's Unreal plugin is currently only supporting PC and Mac development/builds.
There are plans in the future to support Android/iOS, however the Agora Unreal plugin beta was recently launched 04/06/2020.
Here are some links to the repos if you would like to try and get started on PC or Mac!
Otherwise, you are totally able to use Agora SDK on Android, just not with Unreal - yet.
Blueprints Quickstart Repo
C++ Quickstart Repo
If you - and anyone reading this - would like to get started with Agora in the Unreal Engine, we have a community program called Agora Allstars that recognizes creativity, and includes a rewards program for completing the Unreal beta!
FYI - this project says it supports Android now.

I, personally, have not tried it yet though.
There is also a C++ equivalent but the documentation does not say it supports Android.

I successfully built and ran the test application from https://github.com/tensorflow/tensorflow/tree/master/tensorflow/contrib/hvx. I'd now like to benchmark HVX against the CPU implementation of https://github.com/tensorflow/tensorflow/tree/master/tensorflow/tools/benchmark, and if possible, the Android camera demo, to see how much it would help, but I wasn't able to find any documentation describing how to build said apps with HVX support (my builds run on the CPU). I'm testing on the Open-Q 820 development board with Android 7.0.
Is utilizing HVX acceleration outside the HVX test application, preferably with the benchmark and maybe the Android camera demos supported yet? If so, could someone please point me in the right direction? Thanks!
Currently, the Android demo app does not support the HVX runtime. But I'm sure that you can use the runtime with Android demo app by replacing .so file with HVX version. If you can wait for the official support, that would be happening soon, but no promise. Let me know if you have any questions :)
I need to convert a video in format ".mov" to ".3gp". I searched on Google and I found some people saying to use ffmpeg.
I search a lot but I don't found any tutorial to how compile ffmpeg for iPhone then convert the video.
Has anyone what have done this or know any tutorial?
Thanks a lot.
ffmpeg has already been ported to the iOS platform:

Alternative: ffmpeg4iphone - Google Code
