  • How to install sharedhostffmpeg on a host running redhat linux while not being root ?

    30 avril 2013, par user2251342

    The shared host is running on Red Hat 4.4.7-3.

    All these packages have successfully installed :
    - presetup.sh, autoconf.sh, automake.sh, libtool.sh, libiconv.sh, libpng.sh, libjpeg.sh, zlib.sh, libwmf.sh, freetype.sh, gettext.sh, gd.sh, ruby.sh, flvtool2.sh, lame.sh, codecs.sh, libogg.sh, libvorbis.sh, vorbis-tools.sh, libtheora.sh, amrnb.sh, amrwb.sh, liba52.sh, facc.sh, faad2.sh.

    That's exactly all the files just before ffmpeg itself !

    I know the error has to do with a library. However, I'm not familiar with libraries. The error message says :

    /usr/bin/ld : /home/xxxxx/lib/libz.a(compress.o) : relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object ; recompile with -fPIC
    /home/xxxxx/lib/libz.a : could not read symbols : Bad value

    BUT, when I look at my zlib log file(sharedhostffmpeg.1.0.2.log.15939), no errors show up.

    Does anyone know how to recompile with fPIC ?

  • What's difference between using ffmpeg vs Native Hls to download M3U8 file ?

    11 octobre 2017, par Mike Ross

    I use youtube-dl to download M3U8 video (Not live streaming )
    But when I download video using Ffmpeg, if i interrupt download it’s not possible to resume downloads
    When i use --hls-prefer-native tag I’m able to resume downloads.
    My question is what’s difference between the both ? And which is best between these two ?
    Only difference I can find is that the video created using Native Hls has no thumbnail in Ubuntu File Manager !!
