ffmpeg screen recording file can't be played with video with windows media player [duplicate]
7 septembre 2021, par The Mr. TotardoI'm new to ffmpeg. Recently I have recorded my screen using commmand
C :\Users\Totzfreelance\ffmpeg.exe -f dshow -i video="UScreenCapture":audio="Microphone (Realtek High Definition Audio)" output1.mp4


But the result (the output1.mp4) can't be played with video (only sound) with Windows media player but I can play it both sound and video using VLC. What's the problem ?


Can you show me the minimalist command how to fix it ?
