webm格式轉換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.
Mozilla即將進行夏威夷之旅,準備成為一個好家庭男人,我要帶上我的妻子和兩個小兒子。 貪吃懲罰? 大概。 無論如何,我一直在瘋狂地使用youtube-dl從YouTube下載卡通作品,并將其放到我們的新iPad上,以使長子在長途飛行中不被占用。
It seems as though YouTube preserves the original video format, since sometimes youtube-dl provides a webm and other times a mp4. ?Since mp3s are iOS' best?friend, I've needed to convert the webm files to mp4. ?The following ffmpeg command will make that happen:
YouTube似乎保留了原始的視頻格式,因為有時youtube-dl提供了webm,而其他時候提供了mp4。 由于mp3是iOS最好的朋友,因此我需要將webm文件轉換為mp4。 以下ffmpeg命令將實現此目的:
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在轉換過程中不要調整視頻質量。 通過這種轉換,我現在可以將視頻正確地傳輸到我的iPad上了。
