From 62965f8e215eec5e6ee93cd0c9e6fed7ad84e15e Mon Sep 17 00:00:00 2001 From: rlaphoenix Date: Tue, 28 Mar 2023 21:27:43 +0100 Subject: [PATCH] Skip tenc boxes that are not version 0 or 1 It seems tenc boxes should only be 0 or 1, yet sometimes it can be above that. It seems some services accidentally use the `tenc` atom code over another. E.g., Netflix sometimes using `tenc` instead of `avc1`. --- devine/core/tracks/track.py | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/devine/core/tracks/track.py b/devine/core/tracks/track.py index 62f618e..9c35b35 100644 --- a/devine/core/tracks/track.py +++ b/devine/core/tracks/track.py @@ -121,14 +121,14 @@ class Track: # look for track encryption mp4 boxes for tenc in get_boxes(init_data, b"tenc"): - if tenc.key_ID.int != 0: + if tenc.version <= 1 and tenc.key_ID.int != 0: return tenc.key_ID # look for UUID mp4 boxes holding track encryption mp4 boxes for uuid_box in get_boxes(init_data, b"uuid"): if uuid_box.extended_type == UUID("8974dbce-7be7-4c51-84f9-7148f9882554"): tenc = uuid_box.data - if tenc.key_ID.int != 0: + if tenc.version <= 1 and tenc.key_ID.int != 0: return tenc.key_ID def get_init_segment(
