  I run the funtion indianull and expected it to convert a video , in my desired format + add logo + add subtitles ! Takes the original Video from on folder , Subtitles from another folder , and converts the video , and saves it in another folder ..

  


  the issue i see only is :
"\[af#0:1 @ 0x600001ad9cb0\] Error sending frames to consumers: No space left on device \[af#0:1 @ 0x600001ad9cb0\] Task finished with error code: -28 (No space left on device) \[af#0:1 @ 0x600001ad9cb0\] Terminating thread with return code -28 (No space left on device) \[out#0/mp4 @ 0x600001dd8540\] video:0KiB audio:0KiB subtitle:0KiB other streams:0KiB global headers:0KiB muxing overhead: unknown"

  


  I do defenitly have over 400GB free on My SSD !
Is an an speciffic folder that is full ? and can not hold any files ?

  


  Any idea how to solve this ? or any suggestion how to try to solve ?

  


• 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 :

  Attempt 2

  


  I then tried copying one of the command examples in the linked ddagrab wiki page, but also no luck.

  


  ffmpeg -f lavfi -i ddagrab -c:v h264_qsv output.mkv

  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 ?
