• How to stream webcam video over RTSP using ffmpeg on Windows 10 ? [closed]

  15 mai 2024, par let me down slowly

  I am trying to stream my laptop's webcam using RTSP protocol using ffmpeg. I am trying to simulate an actual IP Camera. I have already tried different tools already including using VidGear python package, and gstreamer but could not get it working. Note : I am on Windows 10. I have tried this command :

  


  ffmpeg -f dshow -s 320x240 -rtbufsize 2147.48M -r 30 -vcodec mjpeg -i video="HD Camera" -f rtsp -rtsp_transport tcp rtsp://localhost:8554/mystream


  


  It turns on the webcam with but prints these logs to the console :

• D3D11 hardware screen recording with ffmpeg using Intel H264 QSV hardware encoding

  13 mai 2024, par Cactus

  I'm trying to screen record using ffmpeg and having it all done via hardware on my Intel integrated graphics.

  


  Specs

  


  For reference, here are my specs :

  


  

  • Windows 11 Pro Version 10.0.22631 Build 22631

  


  • Model : Dell Inc. OptiPlex 3090

  


  • Processor : 11th Gen Intel(R) Core(TM) i3-1115G4 @ 3.00GHz, 2995 Mhz, 2 Core(s), 4 Logical Processor(s)

  


  • Terminal : Windows Terminal using Windows Powershell

  


  


  In this wiki, it looked like I could use the "Windows 8+ Desktop Duplication API" to be "directly encoded by a compatible hardware encoder" — so I thought that I could use h264_qsv to encode, allowing me to record without much performance overhead costs.

  


  Attempt 1

  


  I've tried copying one of the command examples, but it didn't work :

  


  ffmpeg -init_hw_device d3d11va -filter_complex ddagrab=0 


  


  Output :

  My main problem is that I don't know how to use really any of these encoders and the examples I've found above don't work with me. What command should I use to screen record all with hardware acceleration on my Intel system ? I don't care about any presets or other options at the moment.

  


  Is there also a way to record audio ? When I tried to use -f dshow -i audio="Stereo Mix (Realtek(R) Audio)" by itself, which I made sure was turned on in Windows' settings and named correctly, it didn't work (is it because I'm using Bluetooth headphones that isn't connected to Realtek's system ?). Should this question be made separately than this one ?

  font's unicode module :

  


  Unicode Module 
 
The Research and Development Unit in the Computer Department at King Fahd Glorious Qur’an Printing Complex relied on the unicode system unicode to create (Hafs) font in the Uthmanic Script, because this system is followed globally among computer and systems manufacturing companies in the world.

Unicode organization is a global code group that is used to define all codes and letters used in most of the world's languages and gathered in one code to facilitate the presentation and delivery on information despite of the language used. This global coding uses 1 to 4 bytes (byte = 8 bits) to encode letters, and so far only a third of the number available in Unicode organization to encode the letters of these languages.

Taking into account Hafs font with the Uthmanic Script, which was built entirely on the unicode system. We can explore the basic letters that were formed according to the following figure:

Whereas the font was developed starting from code (0600 ) to code (066FF ) Taking into account there are several encoded letters that haven't been used at all so it was replaces with the code []. The displayed copy above is the one that is been developed from the basic Arabic coding (0600-06FF) which was updated by Unicode organization in 2009.


  


  expected result :
exported video with correctly rendered text using the given font.

  


  actual result :
the text rendered contains only the diacritical marks ( which are the accents on top of the letters ) without the actual letters.


  


  what i tried :
this is my test command which exports just an image for faster results :

  


  Ffmpeg -loop 1  -i "image-2.jpg" -vf "drawtext=text='بِسْمِ ٱللَّهِ ٱلرَّحْمَـٰنِ ٱلرَّحِيمِ':fontsize=124:fontcolor=white:fontfile='UthmanicHafsV22.ttf':x=(w-text_w)/2:y=(h-text_h)/2" -frames:v 1  "output.png"


  


  

  • tried adding ft_load_flags , almost tried all of them

  


  • tried text_shaping=1 , with no success

  


  • tried textfile instead of text

  


  • tried changing the font, any font i try with it always have different problems, either some squares instead of the diacritical mark

  


  


  p.s im having same results on both latest ffmpeg compiled by myself on macos terminal with all required libraries enabled , and also on flutter ffmpeg kit full gpl
