After checking, I found that this file is almost the same as my file, so the patch script still applies.
Please try this updated script:
import hashlib
import os
r = ['669066909066906690', 'B801000000', '30']
s = [(0x1F28, 0), (0x48F5, 1), (0x4921, 1), (0x4953, 1), (0x4975, 1), (0x9AC8, 2)]
prefix = '/var/packages/CodecPack/target/usr'
so = prefix + '/lib/libsynoame-license.so'
print("Patching")
with open(so, 'r+b') as fh:
full = fh.read()
if hashlib.md5(full).digest().hex() not in ['fcc1084f4eadcf5855e6e8494fb79e23', '923fd0d58e79b7dc0f6c377547545930']:
print("MD5 mismatch")
exit(1)
for x in s:
fh.seek(x[0] + 0x8000, 0)
fh.write(bytes.fromhex(r[x[1]]))
lic = '/usr/syno/etc/license/data/ame/offline_license.json'
os.makedirs(os.path.dirname(lic), exist_ok=True)
with open(lic, 'w') as licf:
licf.write('[{"appType": 14, "appName": "ame", "follow": ["device"], "server_time": 1666000000, "registered_at": 1651000000, "expireTime": 0, "status": "valid", "firstActTime": 1651000001, "extension_gid": null, "licenseCode": "0", "duration": 1576800000, "attribute": {"codec": "hevc", "type": "free"}, "licenseContent": 1}, {"appType": 14, "appName": "ame", "follow": ["device"], "server_time": 1666000000, "registered_at": 1651000000, "expireTime": 0, "status": "valid", "firstActTime": 1651000001, "extension_gid": null, "licenseCode": "0", "duration": 1576800000, "attribute": {"codec": "aac", "type": "free"}, "licenseContent": 1}]')
print("Checking whether patch is successful...")
ret = os.system(prefix + "/bin/synoame-bin-check-license")
if ret == 0:
print("Successful, updating codecs...")
os.system(prefix + "/bin/synoame-bin-auto-install-needed-codec")
print("Done")
else:
print(f"Patch is unsuccessful, retcode = {ret}")
