Ich versuche, alle verfügbaren Dateien mit unterschiedlichen Eigenschaften eines einzelnen Videos mithilfe der YouTube-API herunterzuladen, aber jede URL, der ich zum Herunterladen des Videos folge, führt zu einem 403.
Skript:
#!/bin/bash
_video_info=$(wget -qO- -- "http://www.youtube.com/get_video_info?&video_id=$1&el=detailpage&ps=default&eurl=&gl=US&hl=en")
_video_urls=$(sed -e 's|%25|%|g' -e 's|%25|%|g' -e 's|%3A|:|g' -e 's|%2F|/|g' -e 's|%26|\&|g' -e 's|%3D|=|g' -e 's|%3F|?|g' -e 's|%2C|,|g' -e 's|%2B|+|g' -e 's|%3B|;|g' -e 's|%22|"|g' -e 's|.*url_encoded_fmt_stream_map=url=\(.*&itag=[0-9]*\).*|\1|' -e 's|,url=|\n|g' <<< "${_video_info}")
_video_formats=$(sed 's|.*fmt_list=\([^\&]*\)\&.*|\1|' <<< "${_video_info}")
while read -r _video_download_url; do
wget "${_video_download_url}"
done <<< "${_video_urls}"
Ausgabe:

Wie Sie der wget
Ausgabe entnehmen können, scheinen die URLs syntaktisch korrekt zu sein, aber die Server geben immer eine 403 zurück. Dies geschieht unabhängig davon, welches Video ich versuche.
Ich versuche, die Dateien von derselben IP-Adresse und demselben Computer herunterzuladen, mit denen ich die Links erstellt habe. Irgendwelche Ideen?
