  • Why does ffmpeg show a corrupted video when receiving stream in MPEG TS format ?

    20 décembre 2019, par Carlo

    I’m trying to stream a CCTV footage using RTP/MPEGTS. I can properly view it in vlc using the following command(I’m using windows 10) :

    vlc --demux ts rtp://239.194.115.71:5000

    vlc

    The problem arises when I tried to receive and play it in ffmpeg using the following command :

    ffplay -f mpegts rtp://239.194.115.71:5000

    I’m getting a semi decent video for the first 5 seconds :

    first5

    After 5 seconds the video gets droopy and corrupted
    (note that the top part of the video seems to be unaffected)

    after5

  • merging Multi-Track MP4 Files with ffmpeg show error time porgress bar

    9 juillet 2024, par EasonWaii

    I need to merge two videos into one using ffmpeg. The resulting video should have two video tracks and one audio track, with the audio track taken from the longer video.

    


    When playing the merged video in a player like PotPlayer or VLC, it should default to playing the shorter video track. However, users should be able to switch to the other video track if they want.

    


    The problem I am facing :
Everything is working fine, except when the player defaults to the shorter video track, it shows the timeline of the longer video track.
