У меня есть приложение, которое загружает через твиттер api chunked upload, и оно наконец работает с фотографиями.
Однако я пытаюсь заставить его работать с видео.
Загрузка не работает из коробки, хотя формат видео - mp4. Рекомендации по загрузке в Twitter: эти
Имея это в виду, у меня пока есть команда ffmpeg:
ffmpeg -i in.mp4 -vf \"scale=1280:720\" -b:v 5000K -minrate 5000K -maxrate 5000K -b:a 128K -r 30 -f mp4 -vcodec libx264 -profile:v high -pix_fmt yuv420p -strict -2 -ac 2 -acodec aac out.mp4
Я все еще получаю "Неправильное видео", и я не знаю почему.
Вот мой вывод mediainfo для out.mp4:

Редактировать: Думаю, я тоже добавлю свой код PHP (Это прерывается в разумном из-за того, что сам файл очень большой):
// Set up Codebird
\Codebird\Codebird::setConsumerKey($consumer_key, $consumer_secret); // static, see README
$cb = \Codebird\Codebird::getInstance();
$cb->setToken($token, $token_secret);
$cb->setTimeout(60 * 1000); // 60 second request timeout
$video = new Video($path);
// Convert to the parameter required by twitter.
$converted = $video->convert();
$path = realpath('videos/' . $converted);
$file = fopen($path, 'rb');
$size = fstat($file)['size'];
$mime_type = mime_content_type($path);
$media = $cb->media_upload([
'command' => 'INIT',
'media_type' => $mime_type,
'media_category' => 'tweet_video',
'total_bytes' => $size,
]);
$success = $media->httpstatus >= 200 && $media->httpstatus < 300; # 2xx
if (!$success) {
throw new TwitterException("Failed to INIT upload for $path...");
}
// APPEND chunks to upload.
$mediaId = $media->media_id_string;
$segmentId = 0;
while (!feof($file)) {
echo "chunk #$segmentId....";
$chunk = fread($file, 512 * 1024); // caps out at 512 MB
echo "chunk size: ". strlen($chunk);
$media = $cb->media_upload([
'command' => 'APPEND',
'media_id' => $mediaId,
'segment_index' => $segmentId,
'media' => $chunk,
]);
$success = $media->httpstatus >= 200 && $media->httpstatus < 300; # 2xx
if (!$success) {
throw new TwitterException("Failed to APPEND to upload for $path, chunk $segmentId...");
}
$segmentId++;
}
// Close file and FINALIZE upload.
fclose($file);
echo "FINALIZING id $mediaId...";
$media = $cb->media_upload([
'command' => 'FINALIZE',
'media_id' => $mediaId,
]);
$success = $media->httpstatus >= 200 && $media->httpstatus < 300; # 2xx
if (!$success) {
var_dump($media);
throw new TwitterException("Failed to FINALIZE upload for $path...");
}
return $mediaId;
Видео - это мой класс ffmpeg, который я вставлю ниже, а $ path - это URL, ведущий к совершенно корректному видео в формате mp4.
Видео. php:
