• loading DLL (ffmpeg) as a new thread

  29 septembre 2023, par johnmeck

  i would like to improve some existing project (VICE, a c64 emulator).

  


  within this emulator, we can record the emulator screen using the ffmpeg dll's.
the problem here is, these dll's are running in the same thread as the emulator itself. this obviously is unfortunate, the recording should happen in realtime, while the emulator keeps running at 100% speed.

  


  the current code simply loads all dll's using a simple

  


  LoadLibrary(name);


  


  so my question is : is it possible to load the needed ffmpeg dll's (5 of them) into a new thread ?

  


  i searched a lot, but failed to find something that really helped me.
although i found GetProcAddress, CreateThread and the likes, which at first sight looked promising...

  


• Live streaming and simultaneous local/server video saving with Insta360/Theta 360 camera [closed]

  13 août 2023, par Fornow

  I'm currently working on a project that involves live streaming video from a 360 camera, specifically the Insta360 and Theta models, while also saving the streamed video either locally or on a remote server. I'm relatively new to both live streaming and working with 360 cameras, so I'm seeking guidance on the best approach to achieve this.

  


  My primary goals are as follows :

  


  


  1. Live Streaming : I want to be able to stream the real-time video captured by the 360 camera to a web platform or application, allowing users to experience the immersive 360 content as it happens.

     


  


  2. Simultaneous Video Saving : In addition to live streaming, I also need to save the streamed video. This can either be saved locally on the device running the streaming process or on a remote server. The saved video should ideally retain its 360 nature and high-quality resolution.

     


  


  


  I've been researching various technologies and frameworks like WebRTC for live streaming, but I'm unsure about the compatibility and best practices when dealing specifically with 360 cameras like Insta360 and Theta. Additionally, I'm uncertain about the most efficient way to save the streamed video while maintaining its immersive properties.

  


  If anyone has experience with live streaming from 360 cameras and simultaneously saving the content, could you please provide insights into the following :

  


  

  • Recommended libraries, SDKs, or frameworks for live streaming 360 video from Insta360 or Theta cameras.

  


  • Tips for ensuring the streamed video retains its 360 attributes and high quality.

  


  • Best practices for saving the streamed video either locally or on a remote server while the live stream is ongoing.

  


  


  Any code examples, tutorials, or step-by-step guides would be greatly appreciated. Thank you in advance for your help !

  


• How to permanently make ffmpeg recognizable from bin/bash in macOS

  10 avril 2022, par Anonymous

  I downloaded a zip for ffmpeg, because brew installation was not compatible with macOS High Sierra 10.13.6. After unzipping, the only file contained was ffmpeg, its icon is similar to the icon of the terminal. I want to get the terminal(which runs bin/bash $SHELL) to permanently recognise ffmpeg command.

  


  If I type :

  


  

  1. echo export PATH="/Users/imac/Documents/ffmpeg:$PATH" > ~/.bashrc

  


  2. source ~/.bashrc

  


  3. ffmpeg
then the command ffmpeg is recognized, so everything is ok.

  


  


  However if I exit the terminal and re-open it, or just restart the computer
ffmpeg gives as output -bash: ffmpeg: command not found. So I have to do every time steps 1 and 2 that were describe above.

  


  


  4. Output of cat .bashrc :
export PATH=/Users/imac/Documents/ffmpeg:/Library/Frameworks/Python.framework/Versions/3.9/bin:/Library/Frameworks/Python.framework/Versions/3.10/bin:/opt/anaconda3/condabin:/Library/Frameworks/Python.framework/Versions/3.9/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin

     


  


  5. Output of echo $PATH :
/Library/Frameworks/Python.framework/Versions/3.9/bin:/Library/Frameworks/Python.framework/Versions/3.10/bin:/opt/anaconda3/condabin:/Library/Frameworks/Python.framework/Versions/3.9/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin

     


  


  


  Note that in step 4 ffmpeg appears(in the location I have it stored) whereas in step 5 ffmpeg is absent. Also I have little knowledge of bash and terminal, so if you can, please be explanatory in answers and/or comments. Thank you very much !
