Saya memiliki beberapa MP4 yang ingin saya unggah ke akun flickr saya tetapi mereka memiliki ukuran maksimum 500mb karena tambang saya hanya sekitar 550, saya berencana untuk membaginya menjadi setengah kemudian mengunggahnya, tetapi saya ingin memastikan semua meta data dimasukkan tetapi sepertinya tidak. Saya telah mencoba masing-masing berikut ini tanpa hasil, (pada akhir posting ini saya memiliki output ffprobe asli dan baru):
ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -map_metadata 0:0 SANY0069A.MP4
ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -map_meta_data SANY0069.MP4:SANY0069A.MP4 SANY0069A.MP4
dengan yang ini saya secara manual menghasilkan meta tag individu yang saya ambil dari perintah ini
ffmpeg -i SANY0069A.MP4 -f ffmetadata meta.txt
ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -metadata major_brand="mp42" -metadata minor_version="1" -metadata compatible_brands="mp42avc1" -metadata creation_time="2012-09-29 09:05:50" -metadata comment="SANYO DIGITAL CAMERA CA9" -metadata comment-eng="SANYO DIGITAL CAMERA CA9" SANY0069A.MP4
menggunakan output dari perintah sebelumnya saya juga mencoba ini:
ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -f ffmetadata -i meta.txt SANY0069A.MP4
Output: output sampel dari perintah pertama saya:
ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -map_metadata 0:0 SANY0069A.MP4

Saya tahu ini sangat panjang tetapi sebenarnya pertanyaan yang cukup sederhana. Saya pikir akan lebih baik untuk memberikan sedetail mungkin.
saran di sini akan bagus,
Terima kasih
creation_time
kecuali (kecuali dihilangkan) dan comment
secara otomatis diatur. Perilaku creation_time
tampaknya bervariasi antara 0.8.12
dan ffmpeg saat ini dari Git; tampaknya tidak menambah / menyalin ini kecuali saya memasukkannya. Saya tidak merujuk pada kode, tetapi tidak menyalin creation_time
ketika menyalin aliran mungkin atau mungkin tidak dianggap sebagai bug tergantung pada siapa yang Anda tanya.
