ffmpeg HLS transcoding and chunks upload to remote server
25 mai 2020, par Georgе StoyanovI am trying to create a so called origin server for storing the hls chunks and the manifest file on a remote server. The sending machine running ffmpeg is with IP :
192.168.178.50
and the web server which has to store both the HLS chunks and the manifest file is with IP :192.168.178.100
. My ffmpeg transcoding command line is :


$ ffmpeg -i 01_llama_drama_1080p.mp4 -profile:v high -level 5.2 -s 1920x1080 -strict -2 -start_number 0 -hls_time 6 -hls_list_size 0 -f hls http://192.168.178.100/hls/test.m3u8

But no matter what method I am using I got in the access log of my apache web server the following errors :



$ tail -f /var/log/apache2/access.log

These are the supported methods on my web server :



$ nmap -Pn -p 80 --script http-methods 192.168.178.100

Starting Nmap 7.01 ( https://nmap.org ) at 2017-06-27 10:47 UTC

Nmap done: 1 IP address (1 host up) scanned in 0.34 seconds




My web server is running apache2 on
Ubuntu 16.04
:


$ apache2 -v

Server version: Apache/2.4.18 (Ubuntu)
Server built: 2017-06-26T11:58:04




So according to the access.log file no matter what method I define in the ffmpeg command line it is always trying to upload the chunks using HTTP POST, but the latter is already supported and the directory I am directing the chunks has even 777 rights. Am I missing something here ?

ffmpeg change the fps value of the MKV container
29 juin 2017, par Marios StaikopoulosI’ve been using the SVP video plugin, and we have come across an issue where an incorrect container fps value is causing audio desync.
It seems a set of videos that are actually encoded at 23.976 fps are showing as 23.81.
How can I remux the file using ffmpeg to make it show 23.976, since the file doesn’t actually need re-encoding ?
I have tried the -r and -framerate options to no avail.
What the file shows with ffprobe, 23.81 fps, when it is actually 23.976 fps
