題 如何使用FFmpeg合併音頻和視頻文件?


這是一個類似的問題 這個。我試過跟隨ffmpeg命令:

ffmpeg -i "video.mpg" -i "audio.mp3" -t 00:01:35.13 -vcodec copy -acodec copy result.with.sound.mpg

我有一些輸出文件,沒有什麼可以播放。

在執行命令時,我收到了大量關於緩衝區下溢和以下內容的消息:

frame=    1 fps=0.2 q=-1.0 Lsize=    4672kB time=00:00:00.00 bitrate=3479365818.2kbits/s
video:909kB audio:3716kB subtitle:0 global headers:0kB muxing overhead 1.021293%

(比特率= 3479365818.2可能是視頻無法播放的原因)。

video.mpg 和 audio.mp3 可以在沒有任何問題的情況下在玩家中進行。

怎麼了,怎麼解決這個問題?

UPDATE

這是完整的未切割控制台輸出:

請包括完整的未切割控制台輸出! - slhck
這個輸出似乎是亂碼。為什麼會 Input #1 (音頻)有一個視頻流(Stream #1:1)?無論如何,你需要輸出是MPEG容器嗎?你不能使用MP4,MOV或MKV嗎? - slhck
我真的不需要輸出為mpeg,但輸入必須是mpeg - Arsen Zahray
那麼,請嘗試使用MKV並報告您的結果。我覺得可能會有所不同。 - slhck
為什麼不嘗試映射? -i input -map 0:0 -map 1:0 - Art Shayderov


答案:


-map 選項(鏈接到ffmpeg文檔: 5.11高級選項)從輸入文件中選擇一個流。首先,您必須指定輸入文件編號,其次是流編號。

如果 -map 未指定,ffmpeg選擇最佳流並且通常正確。但是從ffmpeg的角度來看,視頻流的優先級高於音頻,因此它從MP3文件中選擇了圖像藝術(標記為視頻)。

要先從第二個文件中選擇音頻流,請嘗試

-i file_0 -i file_1 -map 0:0 -map 1:0

然後你的其他選擇。這也適用於沒有圖像藝術的MP3文件(第二流)。
