Bagaimana cara mengunduh video dengan url gumpalan?

Saya mencoba mengunduh video dengan url src blob:https%3A//www.youtube.com/23aea5c8-9ae2-40dc-9417-e675ea99b386.

Apakah ada proses yang dapat diikuti untuk mengunduh semua jenis video ini?

Saya menemukan cara untuk men-download video dengan blob urldi Vimeo(membaca di sini saya mengerti bagaimana melakukannya). Saya menulis langkah-langkah sederhana di sini. Saya menggunakan Google Chrome:

1. Buka More Tools→Developer Tools

2. Periksa apakah di tag video ada sesuatu seperti ini:

   <video preload="" src="blob:https://player.vimeo.com/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"></video>
   

3. Salin src dari tag iframe, jika ada, sesuatu seperti http://player.vimeo.com/video/XYZjika Anda menemukannya Anda dapat langsung ke titik 7, jika tidak ikuti langkah 4, 5, 6.

4. Sekarang cari string ini https://skyfire.vimeocdn.com/.../master.json?base64_init=1di dalam halaman (menggunakan Tampilan Pengembang), Anda harus menemukannya di dalam fungsi javascript, seperti ini:

   (function(e,a){var t={"cdn_url":"https://f.vimeocdn.com","view":1,"request":{"files":{"dash":{"origin":"gcs","url":"https://48skyfiregce-a.akamaihd.net/.../master.json?base64_init=1","cdn":"
   

5. Salin tautan di dalam bidang url pada tab Chrome baru, misalnya https://48skyfiregce-a.akamaihd.net/.../master.json?base64_init=1akhiri dengan browser, itu akan membuka Anda file json seperti ini:

   {
       "clip_id": XYZ,
       "base_url": "../",
       "video": [
                    { ... ... ...
   

6. Sekarang buat url dengan id Anda XYZseperti ini:https://player.vimeo.com/video/XYZ

7. Ganti blob:https://player.vimeo.com/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXXdi dalam tag video dengan url terakhir (yang dibuat pada langkah sebelumnya # 6).

8. Sekarang Anda akan melihat bahwa secara ajaib bidang src di dalam tag video berubah (jika tidak, coba langkah 7 beberapa kali) ...

   <video preload="none" src="https://fpdl.vimeocdn.com/vimeo-prod-skyfire-std-us/XX/XXX/X/XXXXXXXX/XXXXXXXXX.mp4?token=abcdefg"></video>
   

9. Gunakan tautan baru itu untuk memuatnya secara langsung, itu seperti ini: https://fpdl.vimeocdn.com/vimeo-prod-skyfire-std-us/XX/XX/X/XXXXXXX/XXXXXX//XXXXXXXXX.mp4?token=abcdefg

Jawaban ini untuk URL Twitter -

1. Klik kanan pada video dan klik Inspect Elements -

Anda akan menemukan kode seperti ini

2. Salin Tempel kode di atas di notepad ++. Mengganti semua "dengan "dan \/wth /di notepad ++. (Gunakan CTRL + H)

Anda akan mendapatkan sesuatu seperti

Dari format JSON di atas, lihat nilai video_url

https://video.twimg.com/ext_tw_video/844504104512749568/pu/pl/e91Du5N2TZ09ZaW_.m3u8

Masalahnya di sini adalah, setelah 1 Agustus 2016, Twitter tidak lagi menggunakan video .mp4, tetapi mengonversi ke HLS baru, format streaming adaptif, dengan ekstensi file .m3u8 .

File .m3u8 pada dasarnya hanya pembungkus file teks, mereka super kecil (300-500 byte), dan ketika Anda membukanya dengan editor teks, file tersebut berisi tautan ke berbagai ukuran video

3. Buka file m3u8 di notepad ++, itu akan berisi kode seperti ini

EXTM3U EXT-X-INDEPENDEN-SEGMENTS EXT-X-STREAM-INF: PROGRAM-ID = 1, BANDWIDTH = 256000, RESOLUTION = 180x320, CODECS = "mp4a.40.2, avc1.42001f" / ext_tw_video / 844504101212 180x320 / _Z42SY5zwMlLdFYx.m3u8 EXT-X-STREAM-INF: PROGRAM-ID = 1, BANDWIDTH = 832000, RESOLUTION = 360x640, CODECS = "mp4a.40.2, avc1.42001f" / ext4504/48/484/48/485/upload_internet.html. Phfjbbx2yinirLi.m3u8

4. Salin masing-masing tautan dari atas sesuai kebutuhan resolusi Anda. Ulangi langkah yang sama sampai Anda memiliki file .ts . Unduh file .ts (file video).

<video src="blob:https://www.example.tv/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx">
  <source src="https://cdn.example.tv/api/media/tv/xyzxyz/index" type="application/x-mpegurl">
</video>

Saya juga punya blob:URL video/@src, tetapi dengan menonton Developer tools> Networkselama pemutaran ternyata itu video/source/@srcadalah URL untuk m3u8daftar putar.

Sebuah m3u8video yang -backed dapat segera diunduh oleh:

• ffplay -i "https://cdn.example.tv/api/media/tv/xyzxyz/1080/index.m3u8"
• ffmpeg -i "https://cdn.example.tv/api/media/tv/xyzxyz/1080/index.m3u8" -codec copy file.mkv

tl; dr - gumpalan URL terdengar seperti biner yang ingin Anda dapatkan tetapi mungkin ada cara yang lebih mudah untuk mendapatkan videonya. Cukup periksa tab Network di Dev tools saat Anda memutar video untuk melihat apa yang sebenarnya Anda ambil.

Saya menemukan cara lain untuk mengunduh video dengan blob urlmasuk Vimeo(lihat jawaban lain di halaman ini).

Solusi ini hanya cocok jika Anda menginginkan video tanpa suara!

Jadi, jika Anda ingin mengunduh hanya video Vimeo (seringkali tanpa suara), saya dapat mengonfirmasi bahwa ekstensi Google Chrome ini bekerja dengan sangat baik: Flash Video Downloader .
