    Le lecteur ne fonctionne pas sur Internet Explorer

  • compile the ffmpeg3.3 for Mac OS show ERROR : libmp3lame >= 3.98.3 not found

    4 mars 2018, par MR.PJ

    I use my mac to compile the ffmpeg3.3 for Mac OS according to https://trac.ffmpeg.org/wiki/CompilationGuide/macOS.I tried the first(which through Homebrew) and third(which builds it yourself) method,the first method is ok.

    But the third, compiling FFmpeg myself and Installing dependencies with Homebrew.I don’t know the meaning of this sentence enter image description here

    after this step :

    ./configure  --prefix=/usr/local --enable-gpl --enable-nonfree --enable-libass \
    --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame \
    --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-libopus --enable-libxvid \
    --samples=fate-suite/

    terminal show :

    RROR: libmp3lame >= 3.98.3 not found

    when I use locate libmp3lame.a,it is at ’/usr/local/Cellar/lame/3.99.5/lib/libmp3lame.a’.

    I also try --enable-libmp3lame --extra-ldflags=-L/usr/local/lib to solve,but it is no effect.

    How to solve thisERROR: libmp3lame >= 3.98.3 not found

  • Why does iftop show no bandwidth from a multicast IP but tcpdump does ? ffmpeg also cannot capture from the multicast

    22 mars 2018, par Lenny

    I ran into a puzzling problem when trying to receive a multicast IP (of a video from 239.193.140.11:1234).

    When $tcpdump dst 239.193.140.11 -w capturedData.pcap, the packets are captured correctly.

    eg, 11:05:25.357138 IP 192.168.34.34.46192 > 239.193.140.11.1234 : UDP, length 1328

    This means that my machine is receiving the multicast IP packets.

    However, when $iftop -i any is run, iftop doesn’t show any bandwidth from 239.193.140.11. Furthermore, when I try to capture the multicast packets with ffmpeg : $ffmpeg -i udp://239.193.140.11:1234?localaddr=192.168.34.34, no packets are captured.

    Why is there a discrepancy between what tcpdump and iftop shows, and how to resolve it so that ffmpeg can capture correctly ?

    lavfi/deinterlace_vaapi : fix can't show full option information.

    use ffmpeg -h filter=deinterlace_vaapi can't get full help information,
    
the root cause is not setting the flags fileld in options.
