• FFMPEG Audio Issues Youtube Live

  2 March 2018, by Geige V

  This issue may have more to do with youtube than ffmpeg, but hopefully someone can help anyway.

  I am having the exact issue described in this post https://productforums.google.com/forum/#!topic/youtube/nHTb7ilKvrw. I would have added to it, but it is locked for some reason.

  I create a stream from a local webm file on my computer using ffmpeg. This file sounds perfectly fine, and still sounds fine when it is sent to platforms other than youtube live (twitch/facebook). On youtube live, however, the audio has static and crackles during the live feed, but the archive of the video on youtube (after processing) sounds perfectly fine. The ffmpeg command is

  ffmpeg -re -i test.webm -acodec aac -vcodec libx264 -ar 44100 -f flv rtmp://a.rtmp.youtube.com/live2/${your_key}

  Webm files from this fiddle (https://jsfiddle.net/2rgv7pgj/) will have the issue.

  If someone could offer advice it would be greatly appreciated.

• Can this be a TC burn-in; 993[1001(1001)1100]1108 - start frame 1001 end 1100 ; (1001) is current frame;993 &1108 are head and tail 8 frame handles

  21 November 2022, by Abraham Thomas

  Need to create a Timecode overlay on videos in frames as "993[1001(1001)1100]1108"
Here -start frame is 1001 and last frame is 1100;
the (1001) is the current frame counter
and 993 and 1108 are head and tail handles (1001-8 and 1100+8)

  


  This is currently done in Davinci Resolve by using below text script (was helped in another forum):
comp.RenderStart+1001-8 .. " [".. comp.RenderStart+1001 .. " (" .. time+1001 ..") " .. comp.RenderEnd +1001 .. "] " ..comp.RenderEnd +1001+8

  


  At times there are 200 + video clips requiring this; if same can be achieved in ffmpeg this will speed up our workflow. Is this possible using a single ffmpeg command; please help

  


  In this forum someone had posted a Timecode overlay command, which gives the current frame number;
I've used this and this below single command works for me:

  


  ffmpeg -i inputvid.mp4 -vf "drawtext=fontfile=Arial.ttf: text='%frame_num': start_number=1001: x=(w-tw)/2: y=h-(2*lh): fontcolor=white: fontsize=55: box=1: boxcolor=black: boxborderw=5" -c:a copy D:\Test\outputvid.mp4

  


  Is there a way to add to this command; the first frame and last frame of the video automatically detected by ffmpeg (I'm on windows);
