webm格式轉(zhuǎn)換mp4

There's an upcoming Mozilla trip to Hawaii on the cards and, in?trying to be a good family man, I'm bringing my wife and two young sons. ?Glutton for punishment? ?Probably. ?Anyways, I've been feverishly?downloading?cartoons from YouTube using?youtube-dl to put onto our new iPad to keep my oldest son occupied during the?long?flight.

YouTube似乎保留了原始的視頻格式，因?yàn)橛袝r(shí)youtube-dl提供了webm，而其他時(shí)候提供了mp4。 由于mp3是iOS最好的朋友，因此我需要將webm文件轉(zhuǎn)換為mp4。 以下ffmpeg命令將實(shí)現(xiàn)此目的：

ffmpeg -i "Spider-Man.webm" -qscale 0 "Spider-Man.mp4"

The qscale 0?directive instructs ffmpeg not to adjust quality of the video during conversion. ?And with this conversion I can now properly?transfer the videos onto my iPad.

qscale 0指令指示ffmpeg在轉(zhuǎn)換過(guò)程中不要調(diào)整視頻質(zhì)量。 通過(guò)這種轉(zhuǎn)換，我現(xiàn)在可以將視頻正確地傳輸?shù)轿业膇Pad上了。
