Corrupted summary text

angry.sardine · 4 April 2020 11:01

Paging @Chillbo as this could be a skin issue.

Check out the following two screenshots, paying attention to the text in the bottom left corner, below the picture. This one looks fine:

This one does not:

It seems to be just that one film that produces corrupted text. I’m not sure what’s special about it.

Here’s MediaInfo for the file in question:

I’m running the 4.9 test build, so it could be connected to that.

Do you have a sample of that file so I could test myself? It looks like the skin is doing something wrong or rather I’ve overlooked an edge case in the conditional visibilities of the media flags.

angry.sardine · 4 April 2020 11:16

I have prepared a sample. Is there anywhere specific that you’d like me to upload it to?

angry.sardine · 4 April 2020 11:37

Okay, you should be able to download the sample from here:

https://www.transfernow.net/files/?utm_source=EusVel042020&utm_medium=&utm_content=en

Chillbo · 4 April 2020 15:41

Will check this out and see what’s up here

Chillbo · 4 April 2020 16:16

Unfortunately, that sample doesn’t help. Kodi is not reading the codec information here at all as the information is delivered in the stream too late (after about 17MB). Therefore, I don’t see any media flag information except the length…

M2TS files don’t have stream information like other containers do. That make them candidates for flaky readouts by Kodi. The default analysis done by Kodi’s ffmpeg is only 50KB. If the information required is not found there, it’s either missing entirely or only partially available.

angry.sardine · 4 April 2020 17:56

Well, it could be that the sample (and the original) are weird in some way; but even so, it’s clear from the way it looks that Kodi is displaying one line of text immediately on top of another instead of below it; and no matter what state the file is in, it shouldn’t be doing that.

I verified that it does the same thing with the sample file.

Chillbo · 4 April 2020 19:02

The issue is I can’t reproduce it here. It looks very much to me like your Kodi has only picked up audio codec information, but no video codec information. In that case the media flags should not show anything as that’s not valid information for a video - which the media flags are only made for.

Could you show me a screenshot of the video info dialog of that video showing both the video information (below the MPAA rating) and the audio stream information (on the second video info dialog page by default)? That could give me a hint as to which information your Kodi database is providing for this particular video.

And could you let me know the output of dpkg -l | grep mediacenter-skin-osmc? As I’ve reworked the media flags again a short while ago, I’d like to make sure you’re using the latest skin version.

sam_nazarko · 4 April 2020 19:07

That (analyseduration) will change to improve some more M2TS playback issues we have been having.

angry.sardine · 4 April 2020 21:07

I’m not sure which dialog you mean. This?

Or this?

osmc@Vero4K:~$ dpkg -l | grep mediacenter-skin-osmc

ii  mediacenter-skin-osmc                18.2.0-37                         all          OSMC skin for mediacenter

Chillbo · 4 April 2020 21:12

The first one of the two is the one I’m looking for. Could you post a screenshot of the second page of that dialog - by pressing the ‘Plot’ button focused in that screenshot?

angry.sardine · 5 April 2020 08:31

Chillbo · 5 April 2020 12:40

Ok. You’re not seeing any audio or video codec information like I do here. Thank you for the screenshots!

Last, but not least: which setting for the media flags have you set in the skin settings under ‘Advanced’?

angry.sardine · 5 April 2020 12:49

Media flags information shown: File first.

darwindesign · 5 April 2020 15:50

FYI you can ssh and run

kodi-send -a TakeScreenshot

instead of using your phone if you want.

angry.sardine · 5 April 2020 16:07

Where does it put the resulting picture?

darwindesign · 5 April 2020 16:10

The first time you take a screenshot it should ask you but the setting is is in settings>system>logging>screenshot folder>

I just set mine to /home/osmc/Pictures/ and grab them via SMB as that folder is already shared by default (if you have SMB installed that is).

Chillbo · 6 April 2020 10:50

Thank you! Although I can’t reproduce, I had one idea what could cause this - although it’s an extreme corner case of Kodi providing only partial information for a video which it normally shouldn’t do.

Hopefully the issue is now addressed with the following commit: #4246783

If you’re on our 3.14 kernel (March update), you may test this via staging (should have synced in about an hour):

Login via the command line
Edit the file /etc/apt/sources.list
Add the following line: deb http://apt.osmc.tv stretch-devel main
Run the following commands to update: sudo apt-get update && sudo apt-get dist-upgrade && reboot
Your system should have have received the update.

Please see if the issue is resolved.

angry.sardine · 6 April 2020 13:22

I’m on 4.9, I’m afraid.

Chillbo · 7 April 2020 07:28

I’m being told that you can use the staging repo while being in the 4.9 testing channel
