ffmpeg converting .mkv to .264

I want to convert .mkv to .264. I try to do it using ffmpeg:

ffmpeg -i input.mkv -vcodec copy -acodec copy output.264

It works without errors, but when I try to play output.264 using ffplay:

ffplay -f h264 -i output.264

ffplay response is:

How I can fix it and convert .mkv to .264 correctly?

You can't put an audio track into a raw H.264 file and you need to use the h264_mp4toannexb bitstream filter to convert the stream to Annex B format:

ffmpeg -i input.mkv -c:v copy -an -bsf:v h264_mp4toannexb out.264

The bitstream filter works without re-encoding.
