Question

四个视频应均匀分布在整个区域。我正在尝试使用此代码，但找不到错误。 logo.png文件的大小为1920x1080。

            <div class='comments-container'>
                @foreach($comments as $comment)
                    <div class="comment-flexbox">
                        <div class="comment-container">
                            <a href='{{ route('profile', $comment->user->username) }}'>
                                <img class='comment-picture' src='{{ url("storage/uploads/profile_pictures/edited/".$comment->user->image_file_name )}}'>
                            </a>
                        </div>
                        <div class="comment-info-container">
                            <a href='{{ route('profile', $comment->user->username) }}'>{{ $comment->user->username }}</a>
                            <p>{{ $comment->comment }}</p>
                        </div>
                        <div class="comment-actions-container">
                            @auth
                                @if(Auth::id() === $comment->user->id || Auth::user()->hasRole('Admin'))
                                    <i class="fas fa-times delete-comment" data-id="{{ $comment->id }}"></i>
                                @endif
                            @endauth
                        </div>
                    </div>
                @endforeach
            </div>

视频“ 01.mp4”中的音轨

Answer 1

每个新叠加层都必须使用以前的叠加层作为主要输入。

ffmpeg -loop 1 -i logo.png -i 01.mp4 -i 02.mp4 -i 03.mp4 -i 04.mp4
 -filter_complex
    "[1:v]scale=960x540[a]; [2:v]scale=960x540[b]; [3:v]scale=960x540[c]; [4:v]scale=960x540[d];
     [0:v][a]overlay=0:0:shortest=1[e]; [e][b]overlay=960:0[f];
     [f][c]overlay=540:0[g]; [g][d]overlay=0:960[video]"
 -y -ss 00:00:00 -t 00:00:05 -b 3000k -map "[video]" -map 1:a? -c:a copy 05.mp4

ffmpeg-多重覆盖-错误在哪里？
