Adding watermark on video while recording

Question

I am trying to add watermark on video at recording time only. But I am not getting any proper solution for it. I have tried this library to add watermark to a video which is already recorded. But this approach takes a long time to add watermark to pre-recorded video. So I changed my approach to adding watermark on video while recording only. Please tell me how can I achieve this.

Answer 1

Look into the ffmpeg library overlay filter to achieve this. Here is the documentation for the above solution.
