変換時のコマンドライン HTTPでのストリーミング(プログレッシブダウンロード)向け処理 何が書き換わるか 備考 変換時のコマンドライン 1. mp4box file.extfile.extを書き換え、上書き 2. mp4box -out new.ext file.extfile.extを書き換えて、new.extに出力。file.extはそのまま残る。 3. mp4box -add file.ext new.extfile.extのデータを取り込んで、新しい動画new.extを作る。 "-new"の使い方がわからない。 2の場合と違い、3は元ファイルの情報が書き換えられる項目がある。例えば、UserDataBox が削除されるため、タイトルとかcopyrightだとかの情報は引き継がれないだろう。 変更・削除されるデータの例： MovieHeaderBoxのCreationTime, TimeScale TrackHeaderBoxのCreationTime HandlerBoxのName ("VideoHandler" → "GPAC ISO Video Handler") DecoderConfigDescriptor の maxBitrate, avgBitrate MPEGAudioSampleDescriptionBox の SampleRate (1000→48000) UserDataBox 削除 HTTPでのストリーミング(プログレッシブダウンロード)向け処理 以下2つの処理を実行したいとする a. moovボックスの後ろにmdatボックスを移動 b. ビデオデータとオーディオデータのインターリーブ mp4box -inter 500 file.ext ※ 前述の1の書式の場合 500はデータをどのくらいの長さに区切ってインターリーブするかをmsecで指定。 bは実施せずに元のファイルのチャンクとインターリーブをそのまま生かし、aのみ実施する、ということはできないらしい。 インターリーブをまったくせずに、ビデオデータの後ろにすべてのオーディオデータを持ってくる場合は -inter 0 を指定。 何が書き換わるか T-01Cで録画した動画を変換した場合 MajorBrand, AlternateBrandの変更MajorBrand 3gp5 MinorVersion 0AlternateBrand isom, 3gp5, 3gp4, mp41, mp42 mdat (MediaDataBox) をmoovの後ろに移動 chunkを再構成 (元よりchunk数が増え、chunk内のsample数は減らされていた) mdatの移動とchunkの再構成に合わせて、stsc (SampleToChunkBox), stco (ChunkOffsetBox)を変更 (audioは未調査) 備考 マニュアル 本家 消えた？ 本家 日本語訳 Windows版は、例えば、Yambに添付のものを利用できる。 名前 コメント

MP4Boxとは x264とNeroAACEncで作った[xxx(Video).mp4]と[xxxcut(Audio).mp4]を結合させるソフト ダウンロード ダウンロードサイト：http //kurtnoise.free.fr/mp4tools/の[MP4Box-0.4.6-rev2125.zip] ダウンロードしたら適当な場所に置いておく 使い方、例 [MP4Box.exeへの絶対パス]\MP4Box.exe -par 1=4 3 -add "[xxx(Video).mp4への絶対パス]\xxx(Video).mp4" -add "[xxxcut.(Audio).mp4への絶対パス]xxxcut.(Audio).mp4" -new "[適当なフォルダ]xxx(放送局 x264 AAC 1440x1080).mp4" をコマンドプロンプトに貼り付けてエンター 簡単な解説 -par 1=4 3 現在の地デジ放送は実はフルハイビジョン(1920x1080)ではなく1440x1080を横に引き伸ばしたものを放送している 当然エンコードは1440x1080で行われる ここでピクセル比を埋め込んで1440x1080の動画を1920x1080に引き伸ばす 1440x1080を1920x1080にするピクセル比は[1=4 3] -add 追加するファイル -new ミックスしてできたファイル、完成品

DVD-Videoの音声付き動画をmp4などにする場合、 DVDのリッピング DVD Decrypterなどのリッピングソフトを使用 リッピングしたファイルを音声付き動画ファイルに変換 AutoGKなどの変換ソフトを使用。コーデックは別途必要 という手順を踏みます。 使うソフトによっては、リッピングしたファイルを映像と音声に分割してから音声付き動画ファイルを生成することもあるようです。 自分は基本的に面倒くさがり屋なので、そういう手間はできるだけ省いていきたいと思っています。

★mp4について★ mp4が見れない人はGOM Playerとか使うといいと思います。 インストールすると他のファイルも GOM Playerで再生するよう設定されてしまうので、 それが嫌な人は、 F5で「環境設定」→「その他」→「関連付け - すべて解除」 その後、「.mp4」だけチェックすればいいと思います。 GOM Player http //www.gomplayer.jp/ ...
