  • Ffmpeg rounds seconds instead of using the milliseconds part

    10 mai 2021, par NourElDineA

    I tried to cut a video using the following command :

    


    ffmpeg -i input.mp4 -ss 00:00:00 -to 00:00:06.600 output.mp4


    


    When I run the command ffmpeg rounds up and the output video is 7 seconds instead of 6.6 seconds.
I would like to know if there is a way to cut the video precisely where I tell it to.

  • Cannot play mp4 video with ffplay, but mpv can

    4 septembre 2021, par guapi

    I want to play a mp4 video on Debian 9.

    


    First, I try to use ffplay to play the video. I use the command ffplay test.mp4, but it cannot play, and display many same errors Receive_frame and send_packet both returned EAGAIN, which is an API violation.. There are detailed logs.

    Then, I try to use mpv to play the video. I use the command mpv test.mp4, and it successfully play the video. There are detailed logs.

    


    $mpv test.mp4

    I don’t know much about video encoding and decoding. Both mpv and ffplay use ffmpeg for video decoding, but why are the results different ?
Thanks in advance.
