• ffmpeg -i desktop Output file does not contain any stream [closed]

  29 novembre 2024, par Antonio

  I'm trying to screen record a remote Windows VM machine which I'm accessing through ssh. I'm executing this command ffmpeg -f gdigrab -framerate 30 -i desktop -t 00:00:10 output.mp4 which is returning the following error :

  If I take a remote desktop connection and use the same command, then it works perfectly.

  


  I've also tried running ffmpeg.exe -f lavfi -i color=c=black:s=800x600:r=30:d=60 out.mp4 which records something but it's just a black screen.

  


  Does anyone have any idea what could be happening ? I'm clueless at this point as I haven't been able to find more info online.

  


• Different container duration between ffmpeg versions which causes audio gaps

  4 septembre 2024, par blits

  I'm trying to make a looped RTMP stream from a single video (in this
example - YouTube), but starting with version 6.0 it introduces a gap in-between loops in the audio which is quite audible. Version before 6.0 (I
tried 5.1.6 and 4.4.2) work as expected and don't introduce any gaps.

  


  The difference I spotted is that the master version (7.0.2) and the 5.1.6, for
example, report a different duration time. Is there any reason why that might happen ?

  


  v5.1.6 :

  


   Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'demo-video.mp4':
   Metadata:
     major_brand     : isom
     minor_version   : 512

     encoder         : Blackmagic Design DaVinci Resolve Studio
   Duration: 00:00:05.00, start: 0.000000, bitrate: 35440 kb/s


  


  v7.0.2 :

  Metadata:
    major_brand     : isom

  As you can see, v5.1.6 report duration of 00:00:05.00 (which is correct) and v7.0.2 is 00:00:05.01 (1ms longer), which is what I think is causing the issue (but I'm not so sure about that). The original file is 5 seconds long which is what can be checked by ffprobe as well, but some streams report a 00:05.01 duration time.

  


  I tried to remedy this issue in many different ways by trimming the video/audio, using different flags, like -shortest, but that didn't help in any way - there's still a gap in the audio which is noticeable when looping the video. And like I said versions such as v5.1.6 work fine and there's no such gap.

  


  I guess what changed between versions is how ffmpeg interprets these streams but in the end I spent 2 days trying to avoid gaps in audio when streaming and nothing helped.

  


  How to reproduce :

  


  You can just stream the video in any RTMP destination of your liking, like YouTube and observe that there would be gaps (audio break-ups) in between every 5 seconds (once video ends). Video is accessible through the link from the curl command

  


  curl -o stream-audio-gap-issue.mp4 https://r2v.streamloop.app/obj_01j6y0pk83fy8vp06a9mmkkqah.mp4
ffmpeg -re -stream_loop -1 -i stream-audio-gap-issue.mp4 -c copy -f flv rtmp://a.rtmp.youtube.com/live2/[your-key]


  


  Expected : there are no gaps every 5 seconds, like in old versions of ffmpeg

  


  Instead : there are tiny audio gaps which are quite noticable

  


  ffprobe outputs is available on gist : https://gist.github.com/blitss/1e221b4fa8885b1df8ac2096746239cf

  


  I'm looking for literally any workarounds that will help avoid audio gaps whilst still preserving the latest version of ffmpeg.
