Errrrgggg.  I'm sure It will be my escaping of special chars.  What version are you using (on the About Tab)?  Is it  the "8 March 2012 - Test Build" as I made some changes around this?

edit - can you run it with the "Turn on verbose logging" and cut and paste the log?  I'm 99% certain I'm not escaping the "&" but I may not get a chance to look at the code (I'm hopefully going on Holidays for a week .... pending COVID lockdowns that is).

[lepa]

it's march 8 test build. SoT seems to parse media info correctly but then inserting to MC field over API the data is cut when handling "&" character

Code: [Select]

I don't know if you've read this post, https://yabb.jriver.com/interact/index.php/topic,119385.msg896632.html#msg896632 where the good lepa thinks my request can be solved by adding a script to your SoT.

Ideally, this script, in addition to detecting the black bars, also cropped, but even if it could only change the aspect ratio tag, that would be a great thing.

Everything comes from my desire to be able to automatically cropping the black bars directly with JRiver, as I said in my post https://yabb.jriver.com/interact/index.php/topic,128769.0.html as with madvr and my RX580 I can only do it with HD files while for those a UHD I would have to change VGA and these days it is very complicated.

[jmone]

I need to open the code up to look at lepa's issue so at the same time I'll have a look at how to get the actual aspect ratio info an aspect ratio tag.  I hope to have a look this weekend.

[lello]

Thank you

I've had a bit of a play using ffmpeg's cropdetect from a windows batch file to see what it produces but I'm not getting to far:

Here is what I'm running over a letterboxed movie

Code: [Select]

ffmpeg.exe -i "\\MAIN\Media\Discs\AQUAMAN\BDMV\stream\00058.m2ts" -vf cropdetect=24:16:0 -vframes 10 dummy.mp4
pause
Here is part of the output looking at the cropdetect

Code: [Select]

[Parsed_cropdetect_0 @ 0000024cea623240] x1:0 x2:3839 y1:0 y2:2159 w:3840 h:2160 x:0 y:0 pts:7507 t:0.083411 crop=3840:2160:0:0
It is reporting the full 3840x2160 frame from what I can see.

Any suggestions on the FFMPEG command?

Thanks
Nathan

it's march 8 test build. SoT seems to parse media info correctly but then inserting to MC field over API the data is cut when handling "&" character

Here is a 64-Bit test build that should fix the MediaInfo issue when trying to update the data in a Field Name that contain an "&".

Let me know how it goes.

Thanks

Any suggestions on the FFMPEG command?

I think vframes 10 means you're just looking at the 1st 10 frames only which is not so much and the content might be different to the actual target content

on my copy of the same file, if I switch to looking at 2s worth of content via

ffmpeg -i 00058.m2ts -t 2 -vf cropdetect -y dummy.mp4

then I see the following after about a second

Code: [Select]

it then sticks at 3840:1600:0:280 for a prolonged period of time

fwiw I found that attempting to use input seeking (-ss before -i) with these files gave v strange results, different output depending on the ss value basically, not sure what is going on there but might be something to watch out for if you were attempting to seek past some initial screens. I guess you could do something like parse the output for the 1st 20s, reduce to the unique detected crop sizes and then either pick one that looks right (e.g. full width and y position indicates equal size bars is surely actual black bar size) or let the user select?

[jmone]

Thanks Matt, that works nicely! 

As a trade off between speed (esp if you are scanning lots of files in one pass) and a good result, I may try 4sec.  I too did not have a lot of luck with -ss and dropping the "suggested"  cropdetect=24:16:0 seemed to also be key.  Anyway, the plan would then to be to just copy the final "crop=" values into a MC Field.

[zybex]

I think it's important to skip a couple of minutes due to all the logos that may not be cropped.
You can try skipping to the nearest keyframe with -noaccurate_seek, and you can also discard the output with -f null.

This works nicely for me (note the dash at the end):

Code: [Select]

ffmpeg -ss 00:05:00 -noaccurate_seek -i input.mp4 -t 5 -vf cropdetect -f null -
I'm testing on an MP4 with black bars, but should work for BluRay too.
"Kursk (2018)" - Unusual format, the first 17 minutes are at 4:3 with side bars, then the rest is at 24:10...

[jmone]

....actually I do have some questions of what to store and in what field.

In MC playback we have
- Crop Options listed as 1.33 (4:3), 1.78 (16:9), 1.85, 2.35, and 2.40
- Aspect Ratio Field that can contain any string and is in a ratio format such as 1:1, 4:3, 16:9 etc (I even have weird stuff like 4400:3285)

So in the above example we have a 3840 x 1600 which I could store as:
- 3840:1600
- 2.4
- 21.6:9 (or as it is commonly and incorrectly called 21:9)

Also is the idea to overwrite the existing "Aspect Ratio" field or add the data to a new field such as "Aspect Ration (Actual)"?

[jmone]

Code: [Select]

ffmpeg -ss 00:05:00 -noaccurate_seek -i input.mp4 -t 5 -vf cropdetect -f null -

I agree that it would be good to skip into the video first, but when trying this I get a bunch of errors:

Try "-map 0" to select just one stream. Those errors are likely caused by ffmpeg trying to seek into empty/invalid subtitle streams.

What about selecting the first video stream with "-map 0:v" ? Place it after the -i arg.
You can also try excluding subtitle streams with "-map 0 -map -0:s"

[jmone]

works but the aspect ratio info is wrong

[zybex]

Strange that it outputs 2 different values for the same timestamp. The @address/value is different, but I don't know what that means.
Is this a 3D movie?

edit: can you please paste the whole output to see what streams it's processing?

[jmone]

Not 3D but 2 video streams.  The real issue is that the aspect ratio is just wrong when you use -ss, it is reporting the full frame and not detecting the black bars.  I've attached the output.

[mattkhan]

seems to be related to the hevc decoder, same commands behave normally when used on a BD as opposed to a UHD

[jmone]

I think Matt is correct.

[zybex]

OK, after googling I think this is what is called "picture in picture" (PIP). It's a feature of M2TS where you can have 2 video tracks in a single stream, or multiple different bounding boxes per frame.
https://forum.makemkv.com/forum/viewtopic.php?t=15253

I'm sure there's a way to select which one of them you want, but there's no way to know which is the correct one.
I suggest you go with this last command/output and just select the highest x*y value from the output. This is usually what is wanted.

[zybex]

Sorry, I missed your reply above.
If it's detecting the wrong resolution with -ss then it's bad :/
What about selecting substream with -map 0:v:0 ?

[jmone]

Yup -ss is bad when combined with cropdetect on these files.

[jmone]

.... so back to the question of what to do with the data anyway,

In MC playback we have
- Crop Options listed as 1.33 (4:3), 1.78 (16:9), 1.85, 2.35, and 2.40
- Aspect Ratio Field that can contain any string and is in a ratio format such as 1:1, 4:3, 16:9 etc (I even have weird stuff like 4400:3285)

So in the above example we have a 3840 x 1600 which I could store as:
- 3840:1600
- 2.4
- 21.6:9 (or as it is commonly and incorrectly called 21:9)

Also is the idea to overwrite the existing "Aspect Ratio" field or add the data to a new field such as "Aspect Ration (Actual)"?

[zybex]

I think it's useful to have both the declared and the detected ratios (meaning, new field for the detected ratio).
Or what about entering the fieldname in SWOT?

[lepa]

Here is a 64-Bit test build that should fix the MediaInfo issue when trying to update the data in a Field Name that contain an "&".

Let me know how it goes.

Thanks
Nathan

Still the same with test build. MC field is cut. Test property "Isolated Music & Effects Track"

[jmone]

Odd - It is working for me (see pic).  In the About tab does it say 17 April 2021 - Test Build?

[lepa]

My MC field is called Extras and I will read the value for it from Mediainfo's Audio:Title/s so in this case

MediaInfo Audio:Title value is  "Isolated Score & Effects"
After running SoT MC [Extras] value will have "Isolated Score " when it should be "Isolated Score & Effects"

So the value of the field will be cut not the field name

I'm using 17 April build

[jmone]

Ahhh got you.  I thought your MC Field was ""Isolated Score & Effects" not that the Data was being read was "Isolated Score & Effects"

[jmone]

Here is another Test Build.

[lepa]

Yup, got that from your picture. Says more than 1000 words as they say 

E: Now working fine thank you

[jmone]

Great!

FYI - I'll need to go through the code and change a bunch of different areas to this URI encode method.... so there will be another test build when I've done that.....

[jmone]

19 April 2021 - Test Build 2 (64-Bit only)

MediaInfo module:  Made some URI encoding changes to handle MC Field Names and Data with characters like "&".

Let me know if I broke anything!  

[lepa]

.... so back to the question of what to do with the data anyway,

In MC playback we have

- 21.6:9 (or as it is commonly and incorrectly called 21:9)

Also is the idea to overwrite the existing "Aspect Ratio" field or add the data to a new field such as "Aspect Ration (Actual)"?

My only motivation is to see real aspect ratio for the actual image content and I myself don't need to do any cropping or anything like that based on it. So I would only use it to select correct aspect ration icon based on the calculation. I wouldn't probably override MC's own aspect ratio field

[lello]

Sorry, but I have understood little, indeed nothing, of what you have written: by chance have you been able to fulfill my request?

[lepa]

19 April 2021 - Test Build 2 (64-Bit only)

MediaInfo module:  Made some URI encoding changes to handle MC Field Names and Data with characters like "&".

Let me know if I broke anything!

Filenames probably still have "& problem"
ref: The Doctor, The Tornado & The Kentucky Kid (2006).mkv

[jmone]

Thanks - seen the "&" on file name issue so I'll take a look and also at storing the actual image ratio in a new Field

[jmone]

Test Build: 17 May 2021

Fixed the "&" Issue on file names that contain it

Added a Crop Detect, but this is for testing only at this stage
- You will need to run SOT --> Configuration --> Save Configuration and it will add a new Field called "Crop"
- Run SOT --> MediaInfo and it will download a copy of FFmpeg and then it will run over the selected files
- At this stage it will only work on single files like MP4, MKV, MOV etc and not on BD, UHD BD, DVD's etc
- At this stage there is no way to "turn it off" so it will run regardless if you want that data or not
- It may take a fair bit of time given it is analysing the first 30 sec of every video file and then storing the value from the last frame

Let me know if this is useful and I'll
- make it more integrated so it works on BD, UHD, DVD's
- make it optional

Also this is the ffmpeg cmd I'm using, so any ideas on improvements would also be worth discussing:

Code: [Select]

ffmpeg.exe -ss 300 -i "%MC_FileNameExt%" -t 5 -vf cropdetect -f null dummy > ffmpg.txt 2>&1
EDIT:  If the ffmpeg build is not downloading and extracting correctly into your [SOT]\ffmpeg folder (blocked by Windows Defender etc), then you can just download the this ffmpeg build manually and extract it to the [SOT Folder]\ffmpeg folder.

[jmone]

So I'm grabbing all the text from the end of the last Crop Line that ffmpeg outputs, and it looks like this at this stage.  I don't really know what the 4 different values are for or how you would use them.  I've also attached a sample of the output from one of the files.

[Hendrik]

The values are w/h and x/y, enough to describe the active image inside the frame.

So 3840:2160:0:0 means the image is 3840x2160 starting at 0:0 - ie. no cropping was detected.

1920:1072:0:4 means the image is 1920x1072, starting at 0:4 .. ie. it wants to crop off 8 lines in total, and the image starts at line 4 from the top (and the second set of 4 lines to crop would be at the end then)

[lepa]

ffmpeg is downloaded again for each run for me. there is a folder called ffmpeg but it its empty

[jmone]

Thanks Hendrik, makes sense when it is explained!

So the next question is how to store the data in MC for the intended purpose for those wanting to change the aspect ratio on playback?  Should it be:
- As it is now
- Less the "crop=" text
- Just the first two #'s (eg 3840:2160 or 3840 x 2160)
- As an Decimal Aspect Ratio to xxx number of places from the first two numbers (eg 1.77 for 3840/2160)
- "Round" to some known Fractional Aspect Ratio based on the first two numbers (I don't like this one).

I've now run it over some more random files and compared it to what MC holds already.

[jmone]

ffmpeg is downloaded again for each run for me. there is a folder called ffmpeg but it its empty

I just tested by deleting my downloaded ffmpeg folder (in the SOT folder) and it download and unzipped the file just fine for me.

Do you see a download progress indicator in the SOT log followed by windows unzipping the file? 

Other wise you could just download the this ffmpeg build manually and extract it to the [SOT Folder]\ffmpeg

I was seeing some Windows Firewall warning it was a dangerous file when downloading it manually but after I hit "keep" it seemed to be fine.

[zybex]

Also this is the ffmpeg cmd I'm using, so any ideas on improvements would also be worth discussing:
ffmpeg.exe -i "filename" -t 4 -vf cropdetect -y dummy.mp4 > ffmpg.txt 2>&1

You can use "-f null dummy" instead of "-y dummy.mp4" to redirect the output to null (doesn't actually create any output file).

[lepa]

Copying manually that build worked. I think that cropping should be determined from some other timestamps than from beginning or from end as there are much black on those points of time in the movies.
Bill & Tedd Excellent Adventure starts with MGM logo which have black all over the border of the picture so it gets crop value of "crop=768:512:568:246" for movie of 1920:1080 with 16:9 display aspect ratio (DAR) without cropping (actual aspect ratio is 2.39:1). Maybe even test multiple points of time and then determine crop from those values.

Also if users are using this to actually somehow crop movies when watching then DAR of uncropped image has to be known also to be able to get aspect ratio of the cropped image correct for both anamorphic and not anamorphic movies. I guess this value is currently strored in [Aspect Ratio] field if MC was able to read it when it analyzed the file.

MediaInfo reads it from "Display aspect ratio". Maybe SoT could write two tags: [Crop] and [Aspect Ratio (cropped)] or something like that. Of course user can read "Display aspect ratio" themself with SoT and then calculate new display aspect ratio with crop applied

+1 for zybex output to null comment

[jmone]

+1 on the "-f null dummy" !  forgot that one  .

So the "hard" bit is finding a single set of parameters that works well "Enough".  Adding -ss 00:05:00 -noaccurate_seek (to get say 5min in) produced weird results last time I look at this but this is a different ffmpeg build so I'll try it again.

At least there are some opensource transcoders which seem to get auto cropping right so it should be possible

Yup still returns odd results on some files

I'm happy to add whatever the variables should be..... but as I'm not going to use this feature, it will need to be someone who knows what it should be, other wise I'm just guessing.  If it turns out to be unreliable or just of little use, then I'll back out this code.

That is perfectly fine and practical approach
