FFMPEG: Outputting multiple videos with watermark

0

Thank you for checking out my post, I'm new to ffmpeg but I'm interested in seeing what I can do with it but I'm facing the following problem:

ffmpeg -f gdigrab -s 1360x768 -i desktop 
       -f dshow -i audio="audio-input-device" 
       -i watermark.png 
       -filter_complex "overlay=main_w-overlay_w-10/2:main_h-overlay_h-10/2;[0:v]yadif,split=2[out0][out1]" 
       -map "[out0]" -c:a aac -c:v libx264 -b:v 2M  -preset ultrafast -s 1280x720 -f mp4 output0.mp4 
       -map "[out1]" -c:a aac -c:v libx264 -b:v 2M -preset ultrafast -s 1280x720 -f mp4 output1.flv

Expected output: Two videos with watermark on the bottom right with audio.

Actual output: Two videos, one of them doesn't have watermark and the other does and both don't have an audio.

Hi Sano, that sounds like an interesting question. However, your code has plenty of options that would take quite some time to get through. Could you create a Minimal, Complete and Verifieble example? That would greatly help us isolate the problem and possible provide a solution.

You're deinterlacing and splitting the original video, not the overlaid one.

It should be,

-filter_complex "overlay=main_w-overlay_w-10/2:main_h-overlay_h-10/2,yadif,split=2[out0][out1]"

Also, it is recommended to deinterlace beforehand, so

-filter_complex "yadif[v];[v][2]overlay=main_w-overlay_w-10/2:main_h-overlay_h-10/2,split=2[out0][out1]"

Thank you so much, It worked but if I may ask, how can I add audio to both of them? – Sano – 2018-12-10T10:17:02.103

Add -map 1:a to each of the output options. – Gyan – 2018-12-10T10:41:52.187
