  • Live stream the screen and microphone to azure media services with ffmpeg

    16 octobre 2020, par Panzer Ihnen

    I'm able to stream a video of my screen to Azure Media Services with ffmpeg, but when I add the audio input, the stream stops with this error :

  • ffmpeg - trying to add a reversed section of original video to the back (boomerang effect)

    23 janvier 2020, par sn0ep

    I have a ffmpeg command as follows which basically scales the video down to 720p. Now i want to add a section to my command which will make a concatination of the video but in reverse. So that the video will also be in a loop like this :

    0s -> 10s -> 0s

    original command :

    ffmpeg -ss 0.0 -to 10.0 -i in.mp4 -filter_complex "fps=15,scale=720:-1" -y out.mp4

    Command after my edits :

    ffmpeg -ss 0.0 -to 10.0 -i in.mp4 -filter_complex "[0:v]fps=15,scale=720:-1,reverse,fifo[r];[0:v][r] concat=n=2:v=1 [v]" -map "[v]" -y out.mp4

    When executing im getting following erorrs :

    Parsed_concat_4 @ 0x7feb89d01d40] Input link in1:v0 parameters (size 720x1280, SAR 1:1) do not match the corresponding output link in0:v0 parameters (1080x1920, SAR 1:1)
    
[Parsed_concat_4 @ 0x7feb89d01d40] Failed to configure output pad on Parsed_concat_4
    
Error reinitializing filters!
    
Failed to inject frame into filter network: Invalid argument
    
Error while processing the decoded data for stream #0:1

    I’m very new into coding advanced ffmpeg commands.

    avutil/imgutils : fix half-float representation of 0.0625

    We don't have a 16-bit float Y format, so no fate changes.
