ffmpeg編輯元數據major_brand

Question

你好，我有一個MP4視頻，我想改變使用ffmepg creation_time，而不改變其餘的元數據。但我面臨一些問題..

major_brand和更多的東西都改變了。我希望那些是一樣的。如果我把它放在ffprobe.exe這是我所看到的：

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '6.mp4': 
    Metadata: 
    major_brand  : mp42 
    minor_version : 1 
    compatible_brands: mp41mp42isom 
    creation_time : 2013-03-23 16:25:53 
    Duration: 00:00:06.55, start: 0.000000, bitrate: 919 kb/s 
    Stream #0:0(und): Video: h264 (Main) (avc1/0x31637661), yuv420p, 480x480, 
862 kb/s, 29.97 fps, 29.97 tbr, 600 tbn, 1200 tbc 
    Metadata: 
     creation_time : 2013-03-23 16:25:53 
     handler_name : Core Media Video 
    Stream #0:1(und): Audio: aac (mp4a/0x6134706D), 44100 Hz, mono, fltp, 62 k 
b/s 
    Metadata: 
     creation_time : 2013-03-23 16:25:53 
     handler_name : Core Media Audio 

我想改變視頻的CREATION_TIME，當我運行：

ffmpeg.exe -i 6.mp4 - 元數據CREATION_TIME = 「2013年6月22日15:00:00」 -acodec副本複印件-vcodec output.mp4

我得到：

Output #0, mp4, to 'output.mp4': 
    Metadata: 
    major_brand  : mp42 
    minor_version : 1 
    compatible_brands: mp41mp42isom 
    creation_time : 2013-06-22 15:00:00 
    encoder   : Lavf55.12.102 
    Stream #0:0(und): Video: h264 ([33][0][0][0]/0x0021), yuv420p, 480x480, q= 
2-31, 862 kb/s, 29.97 fps, 19200 tbn, 600 tbc 
    Metadata: 
     creation_time : 2013-03-23 16:25:53 
     handler_name : Core Media Video 
    Stream #0:1(und): Audio: aac ([64][0][0][0]/0x0040), 44100 Hz, mono, 62 kb 
/s 
    Metadata: 
     creation_time : 2013-03-23 16:25:53 
     handler_name : Core Media Audio 
Stream mapping: 
    Stream #0:0 -> #0:0 (copy) 
    Stream #0:1 -> #0:1 (copy) 
Press [q] to stop, [?] for help 
frame= 194 fps=0.0 q=-1.0 Lsize=  738kB time=00:00:06.61 bitrate= 913.9kbits 
/s 

根據輸出，因爲我選擇「-acodec copy -vcodec copy」，所有內容應保持不變。但是當我爲新創建的.mp4文件運行ffprobe時。這裏是輸出：

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'output.mp4': 
    Metadata: 
    major_brand  : isom 
    minor_version : 512 
    compatible_brands: isomiso2avc1mp41 
    creation_time : 2013-06-22 15:00:00 
    encoder   : Lavf55.12.102 
    Duration: 00:00:06.62, start: 0.000000, bitrate: 913 kb/s 
    Stream #0:0(und): Video: h264 (Main) (avc1/0x31637661), yuv420p, 480x480, 
862 kb/s, 29.97 fps, 30 tbr, 19200 tbn, 38400 tbc 
    Metadata: 
     creation_time : 2013-06-22 15:00:00 
     handler_name : VideoHandler 
    Stream #0:1(und): Audio: aac (mp4a/0x6134706D), 44100 Hz, mono, fltp, 62 k 
b/s 
    Metadata: 
     creation_time : 2013-06-22 15:00:00 
     handler_name : SoundHandler 

正如你所看到的一切已經改變，即使我選擇保持一切都一樣。

請幫我解決這個問題。謝謝！

Answer 1

現場解決方案使用python腳本存在。

1. 安裝的Python 3.3.2

2. 下載movmd.py（它可能與去年的2.7系列，但未經測試工作）從GitHub

movmd.py可以改變所有的日期在你的MP4就地（真的很快）

python movmd.py mp4File.mp4 "2013-07-29 00:00:00" 

提取了mp4 inf o與ffmpeg，我得到：
