Use ffmpeg to trim off X seconds of a y4m video

I'm trying to trim the first second off some .y4m videos.
Using the answer provided here, I am able to trim the first second off a .mp4 video and then play back the output video:
ffmpeg -ss 1 -i input.mp4 -vcodec copy -acodec copy output.mp4
When I try to use the same command with a .y4m video, however, I get the following error and the file that is output is blank:
ffmpeg -ss 1 -i input.y4m -vcodec copy -acodec copy output.y4m
yuv4mpegpipe @ 0x5628e3af63c0] ERROR: Codec not supported.
Could not write header for output file #0 (incorrect codec parameters ?): Invalid data found when processing input
Why is this command not working with a .y4m file? Do I need to add additional parameters? Is there another way to trim the first second off a .y4m video?

Due to a change in the Y4M muxer, you'll need to re-encode, but this is a lossless op.
ffmpeg -ss 1 -i input.y4m output.y4m
Y4Ms can't have any audio, so audio codec option removed.
