`ZRGB32` not working

[miyabi-no1-fan]

reproducible example:
OS = Linux

cargo new --bin x
Add ffmpeg-next = "9.0.0" to Cargo.toml

Copy https://github.com/zmwangx/rust-ffmpeg/blob/master/examples/dump-frames.rs, and paste to src/main.rs

Then, modify

rust-ffmpeg/examples/dump-frames.rs

Line 28 in 3751e28

Pixel::RGB24,

To:

Pixel::ZRGB32, 

When I cargo run -- test.mp4
I get an error message:
Error: ffmpeg::Error(1668179714: Output changed)

The same error still happen even if I modify line 66, 3 to 4 (the size of 1 pixel of RGB24 = 3 but ZRGB32 = 4)
