• Pushing on-fly transcoded video to embeded http results with no seekbar

  11 juillet 2017, par BigRetroMike

  I’m trying to achieve a simple home-based solution for streaming/transcoding video to low-end machine that is unable to play file properly.

  I’m trying to do it with ffmpeg (as ffserver will be discontinued)
  I found out that ffmpeg have build in http server that can be used for this.

  The application Im’ testing with (for seekbar) is vlc

  I’m probably doing something wrong here (or trying to do something that other does with other applications)

  My ffmpeg code I use is :

  d :\ffmpeg\bin\ffmpeg.exe -r 24 -i "D :\test.mkv" -threads 2 -vf
  scale=1280:720 -c:v libx264 -preset medium -crf 20 -maxrate 1000k
  -bufsize 2000k -c:a ac3 -seekable 1 -movflags faststart -listen 1 -f mpegts http://127.0.0.1:8080/test.mpegts

  This code also give me ability to start watching it when I want (as opposite to using rtmp via udp that would start video as soon as it transcode it)

  I readed about moving atoom thing at file begging which should be handled by movflags faststart

  I also checked the -re option without any luck, -r 25 is just to suppress the Past duration 0.xx too large warning which I read is normal thing.
  test file is one from many ones with different encoder setting etc.

  The setting above give me a seekbar but it doesn’t work and no overall duration (and no progress bar), when I switch from mpegts to matroska/mkv I see duration of video (and progress) but no seekbar.

  If its possible with only ffmpeg I would prefer to stick to it as standalone solution without extra rtmp/others servers.

• ffmpeg runs in terminal but returns error in subprocess.run from flatpak-installed pycharm

  19 juin 2024, par name

  I want to run this command in python :

  


  ffmpeg -ss 00:00:30 -i "/home/exl/—1—ARCHIVE—1—/video/music videos/author --- a2 - name (text).webm" -vf scale=150:-2 -vframes 1 -c:v libwebp -compression_level 6 -quality 100 /home/exl/—1—ARCHIVE—1—/—3—previews—3—/734a8a0bac3a83e0f6c69416a26ec5cd211a6d742f3df63bb72bdbe6431b57c30677bc11551ba4aaaecac15ed2c48de51340a09020b7e9d9479e1e81ff766191.webp


  


  In terminal it works fine, but in subprocess returns error. Python code :

  


  finished_process = subprocess.run(

  As suggested here (FFMPEG command runs in terminal but not by subprocess) i tried using which determine path to correct version, but this command returns /usr/bin/ffmpeg both in python and in terminal.

  


  which ffmpeg (both subprocess.run(['which', 'ffmpeg'], capture_output=True).stdout and terminal) : /usr/bin/ffmpeg

• output stream video produced by ffmpeg gets divided into sections on screen upon streaming

  22 avril 2024, par Kaustubh Sonawane

  I'm trying to combine cv2 frames with numpy audio array to produce a hls playlist. I'm giving input using pipe. The problem is that while streaming the output hls playlist produced by ffmpeg, the video screen is divided into 4 parts and the sizes of the 4 parts keep getting changed slowly.
Also the audio is extremely distorted.
  
Attaching images for reference :
at timestamp 00:00
at timestamp 00:03

  


  Here is the script I have written until now :

  


  import cv2

import numpy as np

  I noticed this packet corrupt error and after some digging on stackoverflow found a flag to drop corrupt packets. But that didn't solve the problem.

  


  If I do not drop the corrupted packets, I get this error, if it helps to give any more info :

  I tried to give bufsize flags too, but even that wouldnt help.

  


  I'm a total beginner to ffmpeg. I tried to give the correct resolution, tried all pix_fmt from the documentation, and also experimented with different values of fps. But the problem with split screen and audio distortion continues.
