  • Quick stream from file which exists

    4 mai 2017, par parsa

    I implement live streaming from mp4 video file which exists on the path with ffmpeg under hls format.
    When my video file have the quality greater than hd720 , in encoding there are so many delays for creating .ts fragments.
    I mean the .ts fragments slowly produced on my path,and because of it I have so many delays in showing the stream.
    Here is my ffmpeg code for streaming :

    ffmpeg -re -i 123.mp4 -s cga -f hls -hls_list_size 0 -c:v libx264 -c:a aac 200p/out.m3u8 
    
              -s nhd -f hls -hls_list_size 0 -c:v libx264 -c:a aac 360p/out.m3u8 
    
              -s hd480 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 480p/out.m3u8 
    
              -s hd720 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 720p/out.m3u8
    
              -s hd1080 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 1080p/out.m3u8

    And here is the console output :

        ffmpeg -re -i ../files/412-887123464/video/412-887123464.mp4 -s cga -f hls -hls_list_size 0 -c:v libx264 -c:a aac ../fil
    
        es/412-887123464/video/200p/out.m3u8  -s nhd -f hls -hls_list_size 0 -c:v libx264 -c:a aac ../files/412-887123464/video/360p/out.m3u8 -s hd480 -f hls -

    But I don’t have any problem for streaming files with creating resolutions from a file which have lower orginal quality than hd1080
    What I can to do ?

  • ffmpeg : simple RTMP streaming

    2 avril 2013, par sajad

    I am trying to launch up a rtmp transcoder server using ffmpeg ; that receives udp MPEG-TS streams as input, transcodes it ; and generates an rtmp output to a URL, that can be accessed by users to receive and play the rtmp stream. All these are expected to be performed in a LAN and the output be accessed by all users.

    1) First I don't know where the URL should point to. Is it enought to specify the IP of the system and some optional port ? Is it neccessary that a program should be listening on that port ?

    2) How I can play the stream on the URL ?

    I use a linux ubuntu machine whith IP=10.1.1.229 and I want to transcode multicast stream on this URL : udp://@224.10.1.1:2001.

    here is the command used to transcode input stream and generate rtmp url "rtmp ://10.1.1.229:2020".

    ffmpeg -y -f mpegts -i "udp://@224.10.1.1:2001" -re -vcodec libx264 -maxrate 700k -r 25 -s 640x360 -deinterlace -acodec libfaac -ab 64k -ac 1 -ar 44100 -f flv "rtmp://10.1.1.229:2020"

    and here is the command by which I am trying to play rtmp stream :

    ffplay rtmp://10.1.1.229:2020

    Any guidance would be helpfull. Thank you.
