ffmpeg : single input file contains multiple streams, how to save each discreetly ?
9 octobre 2017, par pinheadI have been given a
.dvsfile which was recovered from some proprietary multi-camera security surveillance system.ffprobereturned errors at first but when I switched the extension to.avcI was able to extract video metadata (output below).ffmpegwas able to read this file and export a long video file that essentially jump-cuts between the different cameras in an erratic pattern, like a crazy music video ! Is it possible to useffmpegto identify the different parallel video streams and output each camera source as its own file ?ffprobe -probesize 1000000000output :ffprobe version 3.2.4 Copyright (c) 2007-2017 the FFmpeg developers

nginx RTMP to HLS : FFMPG error when trying multiple bitrate output [on hold]
28 mai 2014, par user3685074I’m currently trying to convert my RTMP Livestream into a HLS with 3 quality-settings.
I followed this guide
I’ve compiled my own FFMPEG and it’s working if I just convert 1 file.
It seems libx264 isn’t able to do multiple encodings at the same time ?I’m using these command :
exec /usr/local/bin/ffmpeg -i rtmp://localhost/src/$name
-c:a libfdk_aac -b:a 32k -c:v libx264 -b:v 128K -f flv rtmp://localhost/hls/$name_low
-c:a libfdk_aac -b:a 64k -c:v libx264 -b:v 256K -f flv rtmp://localhost/hls/$name_mid
-c:a libfdk_aac -b:a 128k -c:v libx264 -b:v 512K -f flv rtmp://localhost/hls/$name_hi 2>>/tmp/ffmpeg.log;this is the output :
