4.10.2391.0 issues on ARM #497
Comments
Hi, It should be rather easy to implement a), I'll probably be able to do that this evening. It'll be much harder to implement b), since we don't know which version of widevine we'll get before downloading the ChromeOS image. If we switched to using the package from the RPi repo (for which I have already prepared some code a while ago), it would become much easier, but afaik we still don't know about the legality of this. |
Thanks for the explanation, I understand that things aren't always straightforward. It would be interesting to know how RPi OS went about producing that package and if it's really above board or not. |
Would be great if some users could test the attached versions, so I can do a release, soon. script.module.inputstreamhelper-0.5.8-install_from-101f947.zip script.module.inputstreamhelper-0.5.8+matrix.1-install_from-101f947.zip |
It works for me |
It works for me. Could install it again. Netflix: Fine, Amazon Prime: Fine. Zattoo PVR: Buffering. So I recopied old lib version. Kodi Leia, Raspi 3. |
RPi 3, OSMC 2022.03-1, script.module.inputstreamhelper-0.5.8+matrix.1-install_from-101f947.zip installed, going to InputStream Helper, Debug, Install Widevine from:... Error Type: <class 'ValueError'> |
Another try with downloading to pc and installing from local usb-stick: |
what worked for me was to copy a working .so, found in this thread xbmc/inputstream.adaptive#678 |
Hi there, |
I did a fresh install of CoreELEC (S905D soc), so I didn't have any backups of Widevine 4.10.2252. From the Chrome OS recovery image, Widevine 4.10.2391 is installed, which makes that my mediaplayer cannot playback streams within several add-ons (YouTube) in a proper manner, frequently buffering happens. After using this version of inputstreamhelper, I could install Widevine 4.10.2252.5, enabling to play streams flawlessly. Thanks for that! By the way, I had no idea what to select when installing the old version of Widevine, I couldn't see upfront what version would be installed, but for some reason it was the right version I was looking for (4.10.2252.5). |
You mean when selecting "install widevine from specific source"? In that case it installs from the source URL specified in the setting right above ("install widevine from:"), which by default (currently) is a ChromeOS image containing Widevine 4.10.2252.5. Sadly one can never know before the download, which version of widevine is included in a ChromeOS image. |
Yes, I had no clue what URL to specify in "install Widevine from:", so I didn't change the default setting. I wanted to install Widevine version 4.10.2252.5, because I knew that is the latest version that works on my media player with a S905D soc, but I had no idea what URL of what repository to specify. I knew there's some Widevine repository as given below, but no idea whether this would work and/or would be safe to do so. |
Hi there, |
The URL which is set by default should currently be ok, so all one has to do is
The following dialog should be easy enough to follow. If at some point the given URL won't work any more, a different one can be specified in the setting "Install Widevine from" before choosing "Install Widevine library from specific source...". |
Hi there
This version of the CDM has pretty bad issues based on user experiences and my own testing. About once a week since mid January users are either opening new issues on the inputstream.adaptive repo or making new forum posts. Unfortunately the cause of their problem isn't very obvious so users are having a hard time getting help.
Is it possible to either:
a) provide a way to be able to retrieve an older image containing 4.10.2252.5
b) prevent upgrading from 4.10.2252.5 to 4.10.2391.0 (or newer versions until we can confirm they function correctly)
c) both of the above
To give a little more detail, printing to log before and after this statement https://github.com/xbmc/inputstream.adaptive/blob/ecccdae020c5e80ff66200664e54bbee990e6474/wvdecrypter/wvdecrypter.cpp#L1269 takes ~5ms on my RPi3b with 4.10.2252.5, and closer to 50-70ms with 4.10.2391.0 . This alone renders streams unwatchable due to the inability of the decoder to provide enough data to keep Kodi's buffer full.
Additionally while trying to implement support for CBC decryption in IA the newer CDM version would crash during routine function calls (CDM timer) for seemingly no reason, the only difference in conditions being the difference decryption scheme and multiple CDM 'sessions'. All is fine in 4.10.2252.5
I can only guess that somehow the TLS relocation stuff/googles compiler somehow affects this or they've released a buggy product. FWIW the libwidevinecdm0 package in Raspberry Pi OS is still shipping 4.10.2252.5
