Export .qctools.mkv Not Saving

[EmCNabs]

I am having an issue exporting to a QCTools Report.

I am trying to export a report with Comments but when I try to export a QCTools Report or Sidecar Report File the file never appears in the selected "Save Destination". It also does not work to Save-Replace a current report with a new version with comments. The new report version does not save.

I have been able to export to an XML.gz but when I try to open that in the QCTools GUI, the GUI crashes.

No error messages have appeared.

[BleakleyMcD]

@dericed anyone else having this problem?

[BleakleyMcD]

We are on QCTools Version 1.2.1 running 12.6.6 on an M1 MacBook Pro.

[dericed]

Can you try the recent daily build

[EmCNabs]

@dericed @BleakleyMcD A step forward!

I updated to the daily build and was able to make a comment and export a QC Tools Report. (Huzzah!)

But then when I tried to open that QCTools Report to check for the comment, QCTools crashed and now I am no longer able to export a QC Tools Report. :(

[ElderOrb]

Just exported .qctools.mkv with 2 comments successfully.

@EmCNabs what OS you are using? Qt5 or Qt6 build of QCTools? Can you please share video causing issues (or try another one to make sure the issue is not video-specific)?

[dericed]

or sharing the qctools report might be sufficient

[EmCNabs]

I have tried with several different mkv videos & reports. They have all had the same issues: either not saving with comments, or saving & then QC Tools crashing when trying to open the .qctools.mkv report with comments.

Laptop info:
Mac OS: Monterey 12.6.5
QC Tools: Version 1.2.1.20230629

Here is a link to a folder with 3 of the qctools.mkv reports I have been using as tests for saving comments.
https://drive.google.com/drive/folders/1nE5XtgvH2EQVHCmQc8p8rxTCL1pZvCbk?usp=drive_link

The one called "Mouse_QCTReport...mkv.qctools.mkv" is the report that is causing QCTools to crash.

[ElderOrb]

@EmCNabs interesting, report has invalid 'stream_index' (-1) and this is the reason for crash on opening. As I can see crash is unrelated to comments. Can you please share video itself ?

[dericed]

@EmCNabs or could you paste the output of ffprobe "/Users/medialab/Desktop/vrecord Capture/Test Tapes/MadAboutTheMouse/Test2_MAtM.mkv" -show_format -show_streams. Was this qctools report generated by QCTools or vrecord? Noting that in the <frame> elements, the stream_index for both the video and audio frames is set to -1 so it's a challenge to correlate the frames to the streams. I'm curious why this happened.

[EmCNabs]

@dericed The "Test2_MAtM.mkv" transfer & original QCTools report were made using vrecord. On 6/28 the comments were added & exported via QCTools.

I ran ffprobe off the copy of the file I have on my laptop. The video transfers are done via Blackmagic UltraStudio 4k mini & vrecord to Mac mini in the office.

[EmCNabs]

QCTools also crashes when I try to open the file "Test_File01.mkv.qctools.xml". I have also added this to the Google Drive folder

Which if I read the QCTools manual correct, should open a report in QCTools.

[BleakleyMcD]

@dericed @ElderOrb @EmCNabs Just wondering if this could be looked into?

[dericed]

Steps to reproduce:

1. make sample: ffmpeg -f lavfi -i testsrc2 -f lavfi -i sine -t 10 test.mkv
2. open in qctools, select a frame and press 'm' and add a comment
3. export legacy xml.gz
4. close test.mkv and reopen, it should load and comment is visible
5. select another frame and add comment
6. rename current legacy xml.gz report
7. export new xml.gz report
8. close test.mkv and reopen, it should crash

In this scenario you now have two xml.gz, when I diff I see in xml #1, the stream_index values are set properly (0 and 1) in xml #2, the stream_index values are set to -1 so impossible to associate frames with their streams.

Also in xml #2, now all video frames include <tag key="qctools.comment" value="N/A"/> if there's no comment (xml #1 only includes comment node if there's a comment).

Also in the xml#1, there is one comment (expected). In xml #2 (when ignoring all the N/A comments) there are two frames with comments, but the first one is repeated.

            <tag key="lavfi.signalstats.UBITDEPTH" value="8.000000"/>
            <tag key="lavfi.signalstats.YBITDEPTH" value="8.000000"/>
            <tag key="qctools.comment" value="comment on first open then save xmlgz"/>
            <tag key="qctools.comment" value="comment on first open then save xmlgz"/>
        </frame>

[BleakleyMcD]

@dericed I'm not sure I follow... is this a bug or is it user error?

[dericed]

It's a bug. The steps I listed reproduce the issue with simple steps for debugging. I was primarily adding notes for @ElderOrb who's working on this one.

[BleakleyMcD]

😎😎😎😎 thanks! @EmCNabs

[dericed]

fixed in #793
