  • Streaming video segments uploaded in real time

    3 avril 2013, par HaneTV

    I have an application that send quicktime video segments (5s) to a nodejs server that convert them into mpeg-ts in order to stream them to a wowza server in real time :

    ffmpeg -i tempPath -c copy -bsf:v h264_mp4toannexb -f mpegts uploadDir/file.ts

    I want to know if there is a way to stream those segments in real time as they come on my nodejs server to a wowza server without interruption (assuming I can get the segments in time).
    I tried an Http live streaming style by making a playlist like this (updated when segments are uploaded)

    #EXTM3U
    
#EXT-X-PLAYLIST-TYPE:EVENT
    
#EXT-X-TARGETDURATION:5
    
#EXT-X-VERSION:3
    
#EXT-X-MEDIA-SEQUENCE:0
    
#EXTINF:5,
    
movie0.ts
    
#EXTINF:5,
    
movie1.ts
    
#EXTINF:5,
    
movie2.ts

    And calling ffmpeg to send it to wowza :

    ffmpeg -re -i hls+file://mypath/uploadDir/playlist.m3u8 -c copy -f flv rtmp://127.0.0.1/live/stream

    but without any success : ffmpeg doesn't want to stream without #EXT-X-ENDLIST tag and removing the 'hls+' produces lots of errors st:0 PTS: 0 DTS: 0 < 4997 invalid, clipping

    Is there a way to accomplish that ?

  • how to reduce ffmpeg compression time

    19 mars 2019, par Virendra Varma

    Hi I am new with FFmpeg and I am trying to compress the video file by using this command

    "-y", "-i", source_file_path, "-s", "480x640", "-r", "24", "-c:v", "libx264", "-pix_fmt", "yuv420p", "-preset", "ultrafast", "-b:v", "512k", "-bufsize",
    
      "3968k", "-crf", "26", "-c:a", "copy", destination_file_path

    currently, it’s taking 3 minutes to compress a 1-minute long file how I can reduce the compressing process time. I am using FFmpeg 4.0. thanks

    EDITED

    I am using an android phone to compress the video and I am using this FFmpeg git library
