謝謝站大的介紹, 使用這個方法下載的影片格式是 .mp4 , 可是, 我的電視無法直接接上USB播放影片, 想說買一個播放器來接電視看, 請問站內高人, 買有註明Mpeg4的播放器就可以播 .mp4 的影片嗎?

(以下的解釋好像說Mpeg4不等同於.mp4)

Key difference: MPEG-4 is a method of defining compression of audio and visual digital data. MPEG-4 can be used for compression of AV data for web, as used for streaming media, for CD distribution, as well as for voice broadcast television applications. The MP4 is a container format. This means that it can be used to store audio and/or video data.


It might seem like MP4 is a shortened form of MPEG-4, however that is not the case. They are two different forms used for different things.

MPEG-4 is a method of defining compression of audio and visual digital data. It was introduced in late 1998 by the ISO/IEC Moving Picture Experts Group (MPEG). MPEG-4 was designated as a standard for a group of audio and video coding formats and related technology. MPEG-4 can be used for compression of AV data for web, as used for streaming media, for CD distribution, as well as for voice broadcast television applications.

MP4, on the other hand, is based on Apple’s MOV file type. MPEG-4 Part 12 was developed from the Apple’s MOV file and eventually resulted in MPEG-4 Part 14, which is the MP4 format. The MP4 is a container format. This means that it can be used to store audio and/or video data. MP4 video and audio can also be streamed over the internet.


MPEG-4 is a video encoding algorithm. It is responsible for how the images are compressed and converted into data. MP4 is actually a container format. And as such, it does not have a standard method of coding the audio or video information. Instead it uses codecs that dictate how the audio or video will be coded. Advanced Audio Coding (AAC) is the most popular codec for compressing audio in MP4 format.

MPEG-4 is a compression format that is used to compress audio and visual digital data on a computer. Comparatively, MP4 is a container format used to store audio and video files. It can even store subtitles for a video file. As a container, MP4 can save audio and video files that have been compressed in different fashions, including as MPEG-4. MP4 is not concerned by how the images are compressed and converted into data. It is just concerned with is how the data for video and audio are stored within the file as well as other relevant information like subtitles, chapters, etc.

有註明Mpeg4的播放器就可以播 .mp4 的影片嗎? 不見得...

您提出的問題，剛好是用戶在多媒體播放最困擾的問題！
答案是：
1. Mpeg4的播放器可以播擴充檔名為 .mp4 的檔案，但不一定每個 .mp4 的檔案都可以播放！
2. 依據MPEG-4 Part 14定義儲存視訊檔案格式，擴充檔名為 .mp4 ，但 .mp4檔案不一定絕對符合MPEG-4視訊格式
＊因為Mpeg4(視訊檔案格式)與 .mp4(擴充檔名)本來代表的就是不一樣的事！

播放多媒體的關鍵是編解碼器(codec 包含視訊、音訊)，所以標示Mpeg4的播放器表示可以讀取.mp4，但能不能正常播放，還要取決於是否視訊、音訊解碼器正常匹配，這也就是為什麼有時候可能發生有影無聲、有時候有聲無影、有時候明明有在讀取資料，卻什麼都沒有！

通常如果片子喜歡，碰巧不能看，我會用MediaInfo，確認編碼器！必要時再改檔名or轉檔！
目前一般 .mp4，常用的視訊、音訊編碼器許多種標準(XviD/AVC/H.264...)，所以廠商一般不打保票的！最理想的還是乾脆搞台舊電腦當多媒體播放器(解碼器自已增加)！

確認您的電腦裡裝了哪些多媒體解碼器？
