player

player example

This example provides an application that reads from stdin for an RGBA stream.

Usage

1. Query for size

ffprobe /path/to/video.mkv

Note the video stream line:

Stream #0:0: Video: h264 (High 10), yuv420p10le(progressive), 640x360 [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc (default)

This line tells us the resolution (640x360) and the frame-per-second (23.98).

2. Running

This command runs player to read from the command ffmpeg for frames that are 640x360 large, quantize them to 16 colors, 1x scale, with dithering, at 23.98fps.

The ffmpeg command re-encodes the given video through -i in RGBA format, which is the only format that player accepts.

go run . -w 640 -h 360 -c 16 -s 1 -d -fps 23.98 -- \
	ffmpeg -hide_banner -loglevel error -i /tmp/apocrypha-op.mkv -f rawvideo -pix_fmt rgba -
