  • 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 ?

    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.

  • 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 ?
