  • 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 ?

  • assign date and time to output file

    3 avril 2014, par Maged E William

    i am working on ffmpeg screen capture and i wan't it to start recording on start up, so i need to give the output video file a name that is different every time i start recording i did find this question very close to what i need, so i ended up with this commands in a batch file :

    @echo off
    
For /f "tokens=2-4 delims=/ " %%a in ('date /t') do (set mydate=%%c-%%a-%%b)
    
For /f "tokens=1-2 delims=/" %%a in ('time /t') do (set mytime=%%a%%b)
    

    
cd /d E:\ffmpeg\bin
    

    
ffmpeg -f dshow -i video="screen-capture-recorder"
    
-c:v libx264 -r 10 -crf 37 -pix_fmt yuv420p E:\%mydate%_%mytime%.flv

    now i get an error in ffmpeg cmd : [NULL @ 0270d2c01] Unable to find a suitable output format for 'E :-04-2014_02:35'

    E :-04-2014_02:35 Invalid argument

    i know it because the special characters in mytime : but i don't know how to change it.
