  Below works but I do get some warnings:

  Great site for info and I have learned quite a bit so far in my quest to learn programming. There are a bunch of us who live stream to youtube and use ffmpeg. All we want to do is with the least amount of flags in our command line and make it simple to send a live rtsp connection from our cameras to youtube. I know we have some command line interpretations that we have wrong or need to be taken out or added. Could any of you assist with what we would need to resolve our yellow warnings and when it appears the rtsp stream crashes. I apologize with the learning curve for entering code into the post.

  


• Why console reports a lot of frame drops on my conversion ?

  24 juin 2020, par Sososlik

  I'm trying to convert a mp4 video file to another H265 mp4 video file. During conversion I'm applying crop, trim and a drawbox.

  
The result file looks good to the eye. But the question is why I see a lot of dropped frames on the console during conversion process ? (last line on the log, parameter "drop=").

  
I searched google, but it says that normal if you do framerate conversion, but I'm not doing that and don't want any framerate change, just apply my filters and convert to H265. What I'm doing wrong ?

• How to deinterlace and encode with hevc_nvenc(10bit) using ffmpeg

  25 juin 2020, par acklack

  I am trying to deinterlace a mpeg2ts video and encode it with hevc_nvenc(10bit) by ffmpeg, but it does not work.

  


  Please tell me how to solve it.
