ffmpeg - Stream media file with alpha channel
What I would like to achieve is to stream a PNG image (containing alpha background) to localhost in order to use it as input to watermark the main video stream. For example I have a ffmpeg process that would stream the png:
ffmpeg -loop 1 -i image_with_alpha_backgroung.png -options options protocol://localhost:3000
Main ffmpeg process:
ffmpeg -i main_video -i protocol://localhost:3000 -filter_complex overlay -f flv rtmp://streaming_server
The main ffmpeg process would listen for that png watermark stream and would insert it only when streamed from the png ffmpeg stream process. How is it achievable? What I have tried is to stream the png with image2pipe format but it transforms the images in mjpeg and also tried to stream .webm files since the vp9 codec supports alpha but when receiving the webm stream the main process doesn't like the input format. Thank you for your attention
