It's the impedance you need to consider, not the physical cable itself.
Video signals, and digital as well, work best if passed through cablews with a 75 ohm impedance. If a cable is designed for these functions, you can pretty much assume that they are interchangable. The fact that they ar terminated in with RCA connectors is an industry standard.
Audio, OTOH, works quite well with virtually any coaxial cable and are fairly non dcritical of the impedance. These can range from anywhere from 50 to 110 ohms. Audio doesn't care. If you notice, that 75 ohm cable used for video falls right smack in the middle here.
Back in the day, audio cables were pretty much anything. Since audio didn't care, most manufacturers were pretty easy to please. When video came along the need for 75 ohm cables became more critical. The same equipment could make both. They would need to retool specifically with 75 ohm cable for video and put different colored RCA jacks on the end. Somewhere, some guy got the idea that since 75 ohm works for everything and it doesn't cost more than the other stuff, why not make ALL RCA cables out of 75 ohm cable and simply change the RCS connectors on the end.
So, modern audio cable will PROBABLY work for video functions, there may still be some of the non 75 ohm stuff out there.
