[markad] überarbeiteter Decoder
-
If you like, you can update the Finnish translation file from plugin/po/fi_FI.po and post it here. This file realy needs a native speaker review.
I made a pull request just for fun: https://github.com/kfb77/vdr-plugin-markad/pull/4
If you prefer not to use PR's just take the po file from my fork. -
I tested automatic logo detection. So far I have saved the logos under /var/lib/markad and let markad use those. I found out that when I run markad manually, it can't find the logo in my recordings from the Finnish channel 6 (or "Kutonen"). However, when markad runs automatically by VDR, it will find the logo.
Has anyone seen a case like this? I'm calling markad like this: markad --log2rec --loglevel 3 --autologo 2 --logocachedir /tmp - 2021-07-22.19.58.6-0.rec/
kfb77 I can send you logs if you want to debug this.

The "logocachedir /tmp" tells markad to search only in /tmp for logos. With "autologo 2" markad will generate logos and store them there as well.
You need to specify "logocachedir=/var/lib/markad" for your demand.

I'll try to explain what I mean. It would be nice if markad could detect the logo automatically from each recording without me saving the logos manually to /var/lib/markad (or anywhere else). The logos tend to change over time.
I used /tmp to get markad to use an almost empty directory where it has access to. In that case the automatic logo detection does not work with a manual markad run. If I set --logocachedir /var/lib/markad when running markad manually, then it will detect the logo (named Kutonen_HD-A16_9-P0.pgm) from the recording and mark ads correctly.
I also set -l /tmpin /etc/vdr/conf.d/50-markad.confand when markad is running during the recording, started by VDR, it will detect the logo from the same channel and same show. It seems to me I've found a case where manual markad runs and automatic markad runs produce different results.

Now we had overlapping posts.

markad never save any logo to /var/lib/markad, it only read from this directory if you or your distribution had saved logos there and you tell markad to read from this directory "--logocachedir=/var/lib/markad"
With --autologo=2 (this is default) it work as you requested. If there is no logo in "--logocachedir=..." it will be searched in the recording. Maybe not with your Finnish recordings, but this can be fixed.

That should not be, please post markad.log. Maybe a bug in sending the parameters from the plugin to markad.

Because I have not saved all the logs, the situation is not quite like I first thought, sorry. I have looked at two recordings. The second recording was actually fine during recording and fine when using manual markad. Contrary to what I said, there is no case where markad by VDR works and manual markad does not.
The first recording is more interesting. I have uploaded the log as markad-successful-7-tries.txt. In this recording, markad says "no logo found in recording, retry in 6nd recording part" and then "cMarkAdStandalone::CheckLogo(): logo search failed". This is what confused me, I always stopped markad after these messages. But when markad goes to ProcessFiles, it finds the logo!
When I add --cut to this recording's markad run, markad segfaults. It tries to load 0004.ts, which does not exist. I have uploaded that log as markad-segfault.txt.

Thats how it works: start logo search after pre-timer, retry 6 times each 5 min to get a clear and good logo result. I you have a bright background, a transparent logo, a special logo from this show or a very short recording this can fail.
Then start processing the recording. If we have still no logo do one retry from start of the recording (usually the broadcast beforehand) and take what ever you got. Better a bad/false logo than nothing.
So what you found in the log is totaly expected.
Two things are not expected: Of cause the crash in closing the last file with --cut and the 3rd try of logo search has a good result, but it does not pass the validation test.
I have to take a deeper look, please tar the recording directory and provide me a download link via PM.

I noticed this specific recording has a "Tokyo 2020" Olympic Games sign below the logo. I'm guessing that affects the logo detection.
Yes, that is quite possible. But this will happen more often in the near future and not only in Finnish recordings. So I can try to adapt markad in this regard.

Thank you, nice work!
