Decryption not working with .webm video for MPD with video/audio keys #372
Comments
Same thing just happened to me with this:
Both video and audio are .webm and decryption seems to be skipped entirely. Using shaka packager manually on it works. |
Hello, excuse me. This 63626465653765363339616330313832 can be found in the mpd file, but where did the 61653836613537613039366561643735 data come from? |
I used pywidevine to get the decryption key. |
Root cause of this issue seems to be that key ID of I've found a way to get key id using shaka-packager. |
I came across this issue today. If you specify an MPD where source video is .webm, and audio/video encrypted with different keys - then N-m3u8DL-RE is not able to decrypt the video and mux files together. The audio is decrypting fine. It's like the tool does not know it can use a key on the video.
e.g.
= audio working, no video
If you use shaka-packager manually on the webm file, it decrypts ok. So I think the tool needs to support this format (webm) better for decryption.
