  • PSNR on live stream

    13 juillet 2018, par Jocheinfa

    I need to measure quality of a live stream, and I was thinking of measuring PSNR. So I was wondering how can I run this test since it is a live stream, I do not have a refence stream or video. Should I look for a reference video of the same resolution and bitrate, like for example a Big buck bunny, and compare against It ?

    Thanks

  • YouTube Live not working with FFMPEG

    29 septembre 2020, par Benedikt Neumayr

    EDIT : It already works. My new router seems to block rtmp traffic. I edited the firewall config and now it works !
    
I'm trying to stream to YouTube with ffmpeg with the following command :

    



    ffmpeg -f alsa -ac 2 -i hw:0,0 -f v4l2 -s 1280x720 -r 10 -i /dev/video0 -vcodec libx264 -pix_fmt yuv420p -preset ultrafast -strict experimental -r 25 -g 20 -b:v 2500k -codec:a libmp3lame -ar 44100 -b:a 11025 -bufsize 512k -f flv rtmp://a.rtmp.youtube.com/live2/45ee-qka9-0djm-796z   


    



    My ffmpeg version 2.8.11 on Linux Mint 18.2 then says :

    



    Input #0, alsa, from 'hw:0,0':
  Duration: N/A, start: 1511081240.166016, bitrate: 1536 kb/s
    Stream #0:0: Audio: pcm_s16le, 48000 Hz, 2 channels, s16, 1536 kb/s 
[video4linux2,v4l2 @ 0xacba60] The driver changed the time per frame from 1/10 to 2/15
Input #1, video4linux2,v4l2, from '/dev/video0':
  Duration: N/A, start: 5907.755626, bitrate: 110592 kb/s
    Stream #1:0: Video: rawvideo (YUY2 / 0x32595559), yuyv422, 1280x720, 110592 kb/s, 7.50 fps, 7.50 tbr, 1000k tbn, 1000k tbc


    



    After that it does nothing for about 3 minutes,then it finally returns the following error :

    



    RTMP_Connect0, failed to connect socket. 110 (Connection timed out)
rtmp://a.rtmp.youtube.com/live2: Unknown error occurred


    



    I used these instructions :

    



    


  • FFMPEG Encryption of Live Streams

    19 juillet 2016, par trueblue

    I am working on ffmpeg live streaming, where in i need to encrypt Live Streams. I am trying to figure out the same. I worked with AES, but it works only on a stored file. Can I use https or rtmpe etc by using private keys, SSL certificates etc ? Anybody who is working on the same, kindly share your thoughts.

    Eg : I am streaming my live cam feed using

    ffmpeg -f video4linux2 -i /dev/video0 http://localhost:8090/feed1.ffm

    I want to take stream1 as Input and Encrypt it continuously. And at the other end I want to decrypt and Play.
