  • 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.

  • Trouble installing ffmpegthumbnailer on Amazon Linux AMI

    30 août 2014, par jnbankston

    I am trying to install ffmpegthumbnailer on a Ec2 instance using Amazon linux. Ffmpeg has been compiled successfully and is working.

    This is my configuration when compiling from source
    ./configure —prefix=/tmp/ffmpegthumbnailer_dir/ —enable-shared —enable-png —enable-jpeg —enable-static —with-pic PKG_CONFIG_PATH=/root/ffmpeg_build/lib/pkgconfig/

    This is the error when I try to make the binary.

    /usr/bin/ld : /root/ffmpeg_build/lib/libavformat.a(allformats.o) : relocation R_X86_64_32 against

    ff_a64_muxer' can not be used when making a shared object; recompile with -fPIC
