How to Split a Video in h264 Format

I'd like to know how to split the video.

Previously, ffmpeg was used to win AVI-style video files.
With this in mind, I would like to use ffmpeg to divide the h264 format video.

ffmpeg-ss 00:00:00-itest.h264-to 00:00:10-c:vayuv thumbnail-000.h264

I tried various options such as -f, -c:vayuv, etc., but only empty videos are output.
(Output file is empty, nothing was encoded)

I'm looking for a site that might be helpful, but I sometimes find common items such as avi, but it seems difficult with h264.

So, I have a question,
1. Is it possible to split the h264 format video using ffmpeg?
2. If possible, what commands should I fill in?

Incidentally, the h264 video does not contain sound.

(According to the question comment, it has been solved by itself, but until the information is provided)

Yes, it's possible.FFmpeg's basic data processing takes the flow of decoding (decoding; decompressing) input videos and then encoding (encoding; compression) in a specified format."Regardless of the input/output file format, we handle video and audio data internally (to some extent).

The commands in the self-resolving comment decode the read input file into H.264 video, extract the 45 second length from the content location 00:03:05 and then export the H.264 video encoding to the output file.

ffmpeg-i "test.h264" -ss 00:03:05 -t 00:00:45.0 "video.h264"

Video codecs are re-encoded, which can significantly change image quality and file size (bit rate).

Note that the command-line option specification order is also meaningful in FFmpeg.For example, writing the -ss option before or after the input file specification -i changes the behavior slightly.(
