  • 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 ?

  • Powerpoint can't show a video with headers. I see green screen

    28 novembre 2017, par zinon

    I’ve created a video using ffmpeg that contains headers.

    My script for creating it is :

    ffmpeg.exe -f rawvideo -vcodec rawvideo -s 560x448 -r 40 -pix_fmt yuv420p -i C_L_560x448_40_static_maxSSIM_QP23_B2.yuv -vcodec rawvideo -qscale 0 -filter_complex "drawtext=fontsize=32: fontfile=FreeSerif.ttf: text='SSIM=0.961': x=(w-tw)/2: y=(lh/2): fontcolor=orange, drawtext=fontsize=22: fontfile=FreeSerif.ttf: text='Bitrate≤1800 [1873 kbps], Frame rate≥40 [43.98 fps]': x=(w-tw)/2: y=(lh/2+30): fontcolor=orange : box=1: boxcolor=0x00000099, drawbox=x=80:y=160:w=220:h=135:color=red@0.5" C_L_560x448_40_static_maxSSIM_QP23_B2_new.avi

    Firstly, media player showed it as green screen. I downloaded

    Media Player Codec Pack

    and now show its correclty.

    However, when I insert it in powerpoint 2016 I have the same problem of green screen. Do you know how to fix this ?

    vlc player can play it correctly. Is there any way to change the player of excel and use vlc player instead ?
