• Trying to download Fragmented MP4 video [closed]

  26 janvier 2021, par Aryan Agarwal

  i want to download a course that I have purchased for my personal use because my access will be removed by 28th Jan.

  


  I was trying to download the video from the dev tools network tab and encountered that the video is fragmented in multiple MP4 files and not TS or M4s.

  


  The most peculiar thing is that it is the exact same link for the download but I am not able to download the video.

  


  This is the network tab feed

  


  This is the link if somebody wants to check it out https://d1z78r8i505acl.cloudfront.net/media/Ubr3VhTyJD5NW/7c71af39/video_1630_1080_1372.mp4

  


• Some modifications for ffmpeg scripts

  21 mars 2021, par FoxFr

  I wish to modify the following script to put some options, obviously if you can explain ... is better my learning

  


  ffmpeg \
-i /dev/video0 \
-r 1 -stream_loop -1 -f image2 -i "/home/pi/videopi/map/map.jpg" \
-stream_loop -1 -re -i "/home/pi/videopi/bed.mp3" \
-filter_complex "[0][1]overlay=enable='lt(mod(t,20),10)'[v];[v]drawtext=textfile=/home/pi/videopi/gps.txt:reload=1:x=30:y=350:fontfile=/usr/share/fonts/truetype/lato/Lato-Black.ttf:fontsize=30:fontcolor=white[v]" \
-map "[v]" \
-map 2:a \
-c:v libx264 -b:v 4000k -maxrate 4000k -bufsize 8000k -g 50 -c:a aac \
-s 640x480 \
-f flv rtmp://a.rtmp.youtube.com/live2/[google_key_stream]


  


  My desired customization :

  


  

  • Add an another webcam (-i /dev/video1) : 30" video0 -> 30" video1 -> 10" image2 -> 30" video0 ... (a loop)

  


  • Add a png overlay on the final comp

  


  • how add a transparent png behind the text

  


  • plug an audio input (by jack) to add over the bed.mp3

  


  • save the file in same time of live (-f flv live.mp4 ??)

  


  


  The part -filter_complex is the most difficult for me to understand

  


  Thanks you very much for you help, it's for finish my personal and important project

  


• Stream microphone from client browser to remote server and pass audio in real time to ffmpeg to combine with a second video source

  4 mai 2021, par fakeguybrushthreepwood

  As a beginner at working with these kinds of real-time streaming services, I've spent hours trying to work out how this is possible, but can't seem to work out I'd precisely go about it.

  


  I'm prototyping a personal basic web app that does the following :

  


  


  1. In a web browser, the web application has a button that says 'Stream Microphone' - when pressed it streams the audio from the user's microphone (the user obviously has to consent to give permission to send their microphone audio) through to the server which I was presuming would be running node.js (no specific reason at this point, just thought this is how I'd go about doing it).

     


  


  2. The server receives the audio close enough to real-time somehow (not sure how I'd do this).

     


  


  3. I can then run ffmpeg on the command line and take the real-time audio coming in real-time and add it as the sound to a video file (let's just say I'm going to play testmovie.mp4) that I want to play.

     


  


  


  I've looked at various solutions - such as maybe using WebRTC, RTP/RTSP, Piping audio into ffmpeg, Gstreamer, Kurento, Flashphoner and/or Wowza - but somehow they look overly complicated and usually seem to focus on video along with audio. I just need to work with audio.
