  • ffmpeg gives an error Option movflags not found

    12 juillet 2013, par Hemant

    In Ubuntu 12.04 LTS I have used -movflags frag_keyframe+empty_moov in my ffmpeg command :

    ffmpeg -i http://filesbe.vocativ.internal.net/03/44/SN/q1/xg/xl/0344SNq1xgxl.flv \

  • ffserver — live streaming to iOS, Android, Flash

    12 juillet 2013, par Stanislav Saranchin

    I'm creating live streaming transcoding from IPTV to Web into several formats like WebM, Flash, HLS using FFServer and FFMpeg at once.

    ffserver.conf located at http://pastebin.com/hUky5Jsh

    Translating of source-stream to FFServer :

    ffmpeg -i udp://239.192.192.1:1234 -s 560x320 http://localhost:8090/feed.ffm

    FFServer's logs showing next :

    Fri Jul 12 11:39:50 2013 127.0.0.1 - - New connection: GET /feed.ffm
    
Fri Jul 12 11:39:50 2013 127.0.0.1 - - [GET] "/feed.ffm HTTP/1.1" 200 4175
    
Fri Jul 12 11:39:50 2013 127.0.0.1 - - New connection: POST /feed.ffm
    
Fri Jul 12 11:39:50 2013 Feed '/tmp/feed.ffm' stream number does not match registered feed
    
Fri Jul 12 11:39:50 2013 127.0.0.1 - - [POST] "/feed.ffm HTTP/1.1" 200 4096

    My brain is very hot after googling solution on the Internet.
