  • How to generate SDP file from FFMPEG

    20 novembre 2016, par MobilityLab

    So, I have been working with FFMPEG on a project that involves streaming video from one computer to another across the internet with RTP. I want to take that into ffmpeg and use ffserver to display it on a local network.

    As I understand it, you need to have a SDP information so that the receiving ffmpeg instance can interpret the RTP stream. Despite what webpages say, I can not find the SDP information in the information printed to the console.

    How can I force the transmitting ffmpeg instance to output the SDP information so that I can use it to configure my receiving end ?

    Right now, I am testing on Windows 7, but the final solution will be on linux.

    The command I’m running for testing is

    ffmpeg -fflags +genpts -i files\2005-SFSD-sample-mpeg1.mpg -threads 0 -r 10 -g 45
    -s 352x240 -deinterlace -y 2005.mp4 -an -threads 0 -r 10 -g 45 -s 352x240
    -deinterlace -f rtp rtp://192.168.200.198:9008

    My ffmpeg information is...

  • how to install "dynaudnorm" audio filter for ffmpeg

    8 janvier 2019, par FranGar

    I am running linux Mint 17 64 bits-kernel 3.13-generic, with the ffmpeg version :

    ffmpeg version 2.4.3-1ubuntu1 trusty6 Copyright (c) 2000-2014

    I need to run the ’Dynaudnorm’ audio to compress audio files in a daily basis. But launching

    ffmpeg.exe -i "in_original.wav" -af dynaudnorm "out_normalized.wav"

    gives :

    [AVFilterGraph @ 0x1efe820] No such filter : ’dynaudnorm’

    The filter developer site explains that the integration in ffmpeg it’s already done for the latest binaries, but in my version (update yesterday) doesn’t show.

    It’s only Windows available ?
