  • FFmpeg Video is not shown, after encoding audio and video

    19 mars 2019, par Ashutosh Singla

    I’m using FFMPEG to encode my video which also has audio in it

    ffmpeg -i .\A0002780.kava23_Fin.avi -c:v libx265 -preset ultrafast -crf 20 -c:a aac output.mp4

    This command is working OK with no errors. But when I play the video, I can hear only audio and can’t see the video.

    Here are the logs of the command :

    Any idea ?
