Comment (by v0lt):
I have a similar problem even if -ss is 0.
ffmpeg version N-92868-g51b356eef8
I run the following commands.
{{{
ffplay "movie.mp4"
ffmpeg -hide_banner -i "movie.mp4" -ss 0.000 -to 603.480 -c copy
"movie.1.mp4"
ffplay "movie.1.mp4"
}}}
"movie.mp4" plays without errors.
"movie.1.mp4" play with an error at the beginning of the playback.
{{{

options
}}}
MPC-HC and MPC-BE players have a black screen at the start of playback.
