PHP を使用して WeChat アプレットのビデオ編集機能を開発するにはどうすればよいですか?

if ($_FILES['video']['error'] === UPLOAD_ERR_OK) { $targetPath = '/path/to/video/files/'; $fileName = basename($_FILES['video']['name']); move_uploaded_file($_FILES['video']['tmp_name'], $targetPath . $fileName); }

$inputFile = '/path/to/video/files/video.mp4'; $outputFile = '/path/to/video/files/output.mp4'; $start = '00:00:10'; // 起始时间 $end = '00:00:20'; // 结束时间 $command = "ffmpeg -i $inputFile -ss $start -t $duration -c:v copy -c:a copy $outputFile"; shell_exec($command);

$inputFile1 = '/path/to/video/files/video1.mp4'; $inputFile2 = '/path/to/video/files/video2.mp4'; $outputFile = '/path/to/video/files/output.mp4'; $command1 = "ffmpeg -i $inputFile1 -c:v copy -c:a copy -f mpegts intermediate1.ts"; $command2 = "ffmpeg -i $inputFile2 -c:v copy -c:a copy -f mpegts intermediate2.ts"; $command3 = "ffmpeg -i "concat:intermediate1.ts|intermediate2.ts" -c:v copy -c:a copy -bsf:a aac_adtstoasc $outputFile"; shell_exec($command1); shell_exec($command2); shell_exec($command3);

$inputFile = '/path/to/video/files/video.mov'; $outputFile = '/path/to/video/files/output.mp4'; $command = "ffmpeg -i $inputFile -c:v libx264 -preset slow -crf 22 -pix_fmt yuv420p -c:a copy $outputFile"; shell_exec($command);

$inputFile = '/path/to/video/files/video.mp4'; $outputFile = '/path/to/video/files/cover.jpg'; $time = '00:00:10'; // 截取的时间点 $command = "ffmpeg -i $inputFile -ss $time -vframes 1 $outputFile"; shell_exec($command);

wx.chooseVideo({ sourceType: ['album', 'camera'], maxDuration: 60, success(res) { const tempFilePath = res.tempFilePath; // 将本地视频文件上传到服务器 wx.uploadFile({ url: 'http://example.com/upload.php', filePath: tempFilePath, name: 'video', success(result) { console.log('视频上传成功'); }, }); // 获取视频封面 wx.createVideoContext("video").getImageInfo({ src: tempFilePath, success(result) { const coverUrl = result.path; console.log('封面截取成功'); }, }); // 其他视频编辑操作... }, });
