• FFMPEG || NGINX RTMP server not naming MPEG DASH chunks

  12 avril 2020, par Mathew Knight

  Feel like i'm smashing my head against a brick wall here, i've been tryin to figure thisout for so long....

  



  Basically i'm trying to send an RTMP stream to my NGINX server running on Ubuntu 18.04, then transcode it to a custom MPEG DASH stream that muxes the stream into 2 streams for audio and video.

  



  as i need to have the chunks in the same destination folder i need to rename them.

  



  when i try the following FFMPEG script it just keeps giving me chunks named for example :

  



  chunk-stream-audio-%05d.webm

  



  the %05d should be the chunk number running consecutively.

  



  Running a similar script on my Macbook the chunks generate correctly... is this an error of have i done something wrong here ?

  



  Here's my FFMPEG script

  



  exec_push ffmpeg -re -an -i 'rtmp://localhost:1935/live/stream' -map 0:v:0 -c:v libvpx-vp9 -s 1920x1080 -bufsize 15000k -b:v 15000k -keyint_min 150 -g 150 -tile-columns 4 -frame-parallel 1 -an -f dash -init_seg_name 'init-stream$RepresentationID$_video.webm' -chunk_start_index 1 -media_seg_name 'chunk-stream$RepresentationID$-video-$Number$.webm' '/home/mathewknight/Desktop/test/video.mpd' -map 0:a:0 -c:a libopus -mapping_family 255 -b:a 1024k -vn -f dash -init_seg_name 'init-stream$RepresentationID$_audio.webm' -chunk_start_index 1 -media_seg_name 'chunk-stream$RepresentationID$-audio-$Number%05d$.webm' '/home/mathewknight/Desktop/test/audio.mpd'  2>>/var/log/nginx/ffmpeg.log;

  


• FFMPEG syntax clarification question for the "between" function [closed]

  31 octobre 2024, par user2571504

  I've been using a crop filter script to hold the crop in one place for the first 750 frames, then automate a moving crop to follow some action in the clip. It's working great for chunky moves (5 pixel jumps as shown below) :

  


  -filter_script:v:0 crop-filter-script.txt

crop='1500:1000:100:
if(between(n,0,750),100,
if(between(n,751,756),105,
if(between(n,757,762),110,
if(between(n,763,768),115,
if(between(n,769,774),120,
if(between(n,775,780),125,
if(between(n,781,786),130,etc


  


  My question is about how "between" is interpreted. Does "between(n,751,756)" mean "frames 751, 752, 753, 754, 755 & 756" ? or does it exclude the start and ending frames, so that it's "between" those two numbers ? Like : 752, 753, 754 & 755 only ?

  


  Thanks !
