HTML5 Video Chrome - ffmpeg - mp4可以在Chrome中工作

我已經使用ffmpeg將文件成功編碼爲.mp4，它將在所有測試過的設備（PC上的Safari，PC上的IE，Android Browser，Andriod Video Player和Safari iPad），除了Chrome。HTML5 Video Chrome - ffmpeg - mp4可以在Chrome中工作

作爲解決方法，我曾計劃在.mp4源文件之前簡單列出.ogg源文件，以便chrome在沒有看到.mp4源文件的情況下播放.ogg源文件，但是，我遇到了這個問題提到here。

基本上，我在正確的ffmpeg命令之後會將.mp4視頻編碼爲可在Chrome中播放的標準 - 當然，在任何其他平臺上都不會丟失播放功能。

我曾嘗試多種組合，如：

ffmpeg -i [filename].wmv -vprofile baseline -level 30 -vf scale=640:-1 -movflags faststart [filename].mp4

等，但還沒有找到獲勝的一個。

編輯：我想：

ffmpeg_new -i [filename].wmv -strict experimental –acodec libvo_aacenc -ac 2 -ab 160k -vcodec libx264 -vf scale=640:-1 -pix_fmt yuv420p -preset slow -profile:v baseline -level 30 -maxrate 10000000 -bufsize 10000000 -b 1200k -f mp4 -threads 0 [filename].mp4

這裏是ffmpeg的輸出：

但仍沒有運氣。 .mp4將在我嘗試過的每個兼容設備/瀏覽器組合中播放，除了chrome ..有什麼建議嗎？

TIA。

像往常一樣，您應該始終包含完整的ffmpeg控制檯輸出。 – LordNeckbeard

@LordNeckbeard：添加了ffmpeg輸入/輸出。仍然無法在Chrome中使用。 – IIIOXIII

的解決方案是使用參數「-pix_fmt YUV420P」：

ps>ffmpeg.exe -i $input\$file -y -strict experimental -acodec aac -ac 2 -ab 160k -vcodec libx264 -s 640x480 -pix_fmt yuv420p -preset slow -profile:v baseline -level 30 -maxrate 10000000 -bufsize 10000000 -b 1200k -f mp4 -threads 0 $output\$file.iphone.mp4

的ffmpeg版本的N- 46936-g8b6aeb1

希望這可以幫助你獲得鉻兼容視頻

更新1

See reference它可能會幫助你

正在編碼的視頻已經是yuv420p格式，因此不需要將其重新格式化爲yuv420p。無論如何，添加'pix_fmt yuv420p'沒有幫助。我從[]（http://ffmpeg.zeranoe.com/builds/）下載的ffmpeg'N-54207-ge59fb3f'版本不包含aac音頻編解碼器或-presets選項，除此之外，我使用了你建議的相同的編碼字符串 - 但它並沒有產生可以被Chrome播放的mp4文件。 – IIIOXIII

@Arhol：感謝您的參考，但是，沒有提供的代碼片段解決了我的問題。我仍然無法編碼可在Chrome中運行的.mp4文件。 – IIIOXIII

「-pix_fmt yuv420p」：此解決方案適用於我，因爲我遇到同樣的問題。 –

請嘗試以下操作，我也有一些麻煩讓mp4文件在Chrome中工作。在我的情況下，即使我將mp4文件拖放到chrome中，mp4文件也無法正常工作。我希望你有同樣的問題。第一步你的mp4文件應該用H.264編碼。在我來說，我不得不改變以下設置： -

輸入chrome：//標誌

搜索如下： -

禁用硬件加速的視頻解碼。

通過選擇禁用選項

重新啓動瀏覽器禁用上述設置。

檢查Chrome是否現在播放mp4文件。如果是，那麼HTML視頻也應該沒有任何問題。

Chrome可能會使用一些H.264視頻驅動加速，可能會破壞舊的驅動程序...嘗試update the video drivers，看看它是否工作。

錯誤的另一個來源可能是視頻的傳輸，而不是解碼。

嘗試打開那些使用「file：// ...」url不起作用的文件：如果可行，問題與傳輸有關，與h264或mp4無關。

雖然這兩個給定的文件在HTML5託管時在我的Chrome中運行良好，但我發現使用更大的mp4文件出現這樣的傳輸問題。在這種情況下，我可以在提琴手中看到取消的請求。

它似乎是Chrome中的一個錯誤，我還沒有找到解決方法。
