Experimental in-progress code to render a raw NTSC video capture to MP4, meaning a capture of 8-bit samples at 28MHz using the CXADC driver to capture video.

-i input capture file, or - to pipe something into STDIN. In my case raw captures are compressed with FLAC and I pipe the output of FFMPEG into STDIN.
-o output MP4 file, I use test.mp4

ok, but you have a sample capture for test myself?

I do not. Any sample would be either too short for useful testing, or too large to add to the repo. It's raw 8-bit samples at 28MHz, which is 28MB per second, after all.

ok, and you can make an encoder for generate it and use the steps?
