• how to install ffmpeg in microsoft fabric [closed]

  15 juillet 2024, par Mango

  I am running a python script on Microsoft fabric notebook using the pydub library, which relies on external audio handling utilities like ffmpeg, to split MP3 files. The ffmpeg utility is not a Python package and must be installed separately in my environment. I use following code

  


  import os

# Set the path to the ffmpeg binaries
ffmpeg_path = "/lakehouse/default/Files/Bronze/Model/test/ffmpeg"
os.environ["PATH"] += os.pathsep + ffmpeg_path

# Verify the PATH environment variable
print(os.environ["PATH"])

# Verify that the binaries are accessible
!ffmpeg -version


  


  but I get error as

  


  /usr/bin/sh: line 1: ffmpeg: command not found


  


  How should I install ffmpeg in microsoft fabric ?

  


• Run Command/Process in Background but return the return code

  14 juin 2019, par techsavy

  I am Looking to run ffmpeg via subprocess, start the command in the background but return a return code so that further steps can be taken based on that return code. (stdout, stderr) = metadata.communicate is throwing all sorts of errors perhaps due to the process still being run.

  metadata = Popen(['/home/linuxbrew/.linuxbrew/bin/ffmpeg', '-i', '/mnt/sniops-ffmpeg/' + str(content.get('asset')), '-i', '/mnt/sniops-ffmpeg/' + str(content.get('asset')), '-lavfi', 'libvmaf=model_path=/opt/vmaf/model/vmaf_4k_v0.6.1.pkl:psnr=1:ssim=1:log_fmt=json:log_path=/mnt/sniops-ffmpeg/vmaf_scores/blackmonday_test1.json', '-t', '00:00:20.00', '-f', 'null', '-', '&'], stdout=PIPE, stderr=PIPE)

• Integrate necessary ffmpeg libraries in own project for MCU (microcontrolers) [closed]

  16 septembre 2023, par Borel Kamnang

  I use two ffmpeg commands here :

  


  ffmpeg -i BigBuckBunny_320x180.mp4 -vf scale=192:96,setsar=1:1 outputBBB.mp4
ffmpeg -i outputBBB.mp4 -vf "fps=12,scale=-1:96:flags=lanczos,crop=192:in_h:(in_w-192)/2:0" -c:v rawvideo -pix_fmt rgb565be BigBuckBunny_192x96_12fps.rgb


  


  The first is to downscale an original video and the second is to convert the scaled video to a .rgb format.

  


  As anew user of ffmpeg, I would like to know what are libraries used for that two command to just integrate them in my Arduino IDE C++ project an just call the necessary functions to do the downscale and the conversion.

  


  And another of my concerns is knowing how I can run any ffmpeg in an Raspberry Pi Pico W (RP2040) or ESP32 microcontroller ?

  


  I tried to include the ffmpeg libraries folder in a created Arduino IDE project for Raspberry pico w and the link for files doesn't work. In addition to having the config.h and config components.h files missing in the folder downloaded from the ffmpeg site, there are too many dependencies between .h and .c files.

  


  extern "C" {
  #include "src/ffmpeg/libavcodec/avcodec.h"       
  #include "src/ffmpeg/libavutil/mathematics.h"
}
void setup() {
   Serial.begin(115200);
   delay(10000);
 }
 loop(){
 }


  


  It's been three days today that I've been trying to compile from Arduino IDE, and correct the links in the files.
The problem is also that I don't even have the certainty of what it will work in the Raspberry Pi PicoW or ESP32 afterwards.
