  • Wrong video duration when recording with ffmpeg

    4 octobre 2018, par lulas

    I am trying to record a H264 video using ffmpeg.

    In order to do this, I am grabbing frames from a video source and pushing them into a pipe that FFmpeg reads from and afterwards writes to a file.

    My problem is that when I record a 10 second video, the file contains the full video sped up, being the final duration 3 seconds...

    I believe the problem I am having might be related with the frame rate, since I am saying to record with 30 FPS, but I can only provide 10 FPS.

    These are the options I use with FFmpeg :

    -thread_queue_size 512 -framerate 30 -f rawvideo -pix_fmt rgb32 -video_size 1920x1080 -i \.\pipe\pipe_name -vcodec libx264 -crf 23 -pix_fmt yuv420p -preset ultrafast -r 30 "output.mp4"

    And these are the FFmpeg logs :

    So, through the logs I can see that I provided around 100 frames in 10 seconds, but FFmpeg wrote all those 100 frames in 3 seconds...

    What can I do to write the 100 frames spread in the 10 seconds ?

    I looked into a FFmpeg option called -vsync, but haven’t had any success with it.
