test wav audio file

Steps to Reproduce:
1. Download the attached sample .wav file and save as "测试音乐.wav". Note that the file name should contain Chinese characters in order to reproduce this bug.
2. New Impress, two slides, go to the first slide. In the transition side bar, use the audio file "测试音乐.wav" as the transition audio, check "Loop until the next sound" checkbox.
3. Save as PPTX.

Current Result:
测试音乐.wav is lost in the PPTX file.

Expected Result:
测试音乐.wav should remain there in the PPTX file.

It is noted that if the file name is "test.wav" (i.e. does not contain Chinese characters), then it works as expected. I also noted that in MSO Power Point, those Chinese characters are allowed.

You may also use the attached odp file and try to save it as PPTX to reproduce this bug.

Adding Tünde Tóth to cc as I see you have recently worked on commit  c2e8a96a8107a37901e475c65a8e61211fc3b132 (tdf#53970 PPTX: fix broken export of linked media files). Would you please take a look? Thanks.

Only partially REPRODUCIBLE with Installation of Version: 7.3.0.3 (x64) 
Build ID a69ca51ded25f3eefd52d7bf9a5fad8c90b87951
CPU threads: 12; OS: Windows 10.0 Build 19044; UI render: Skia/Raster; VCL: win | Locale: de-DE (de_DE); UI: de-DE | Calc: threaded | ElementaryTheme | My normal User Profile.

1. I opened .odp, added 测试音乐.wav astransition sound tested (played) during  
   transition, everything fine.
2. I saved, closed and reopened new.odp: everything fine.
3. I saved, closed new.odp as new.ppts, reopened and played: 
   no sound on transition
4. I checked in Transition sidebar: 测试音乐 still did exist in list, but has
   gone lostas sound for transitoins.
5. I added 测试音乐  from list, and worked fine again when I played presentation.

a)currently I can't tell if the problem occurs when saving as .pptx or if it occurs when reopening the .pptx in LibO. I have no other presentation 
@Kevin Suo: your result for question (a)?
Comment 4 Rainer Bielefeld Retired 2022-04-09 15:55:46 UTC
a) Might (also) be a FILEOPEN problem? 

11: Open new.pptx with 'SoftmakerPresentation' → Start presentation
   » No sound played during transition
12: Add 测试音乐.wav as transition sound in softmaker → Start presentation
   » Sound plays
13: save as newsoftmaker.pptx and close
14. open  newsoftmaker.pptx in LibO → Start presentation
   » sound plays during transition as expected             but:
     in transition sidebar no transition is selected

a1) So I can't tell 100% sure wheter in (11) sound really has become "lost" or
    Softmakeronly did not recognize it?
    But I am pretty sure that it's a FILESAVE problem

Reproduced with:

Version: 7.2.6.2 / LibreOffice Community
Build ID: b0ec3a565991f7569a5a7f5d24fed7f52653d754

Comment 6 Stéphane Guillou (stragu) 2022-04-14 15:47:18 UTC
Also in:

CPU threads: 8; OS: Linux 5.13; UI render: default; VCL: gtk3; 
Locale: en-AU (en_AU.UTF-8); UI-Language: en-US

I can still play the transition when saving as PPTX and keeping Impress open, but as soon as I close and reopen, the transition is gone. I can add the transition again and play it, but it is lost again when closing and reopening.

Looks like the file name encoding is changed for the worse.

How the insides of the Hungarian pptx attachment look like

So this really affects any non-ASCII characters, when I rename a working wav file (https://www2.cs.uic.edu/~i101/SoundFiles/preamble10.wav) to preambleárvíztűrőtükörfúrógép.wav then the file is incorrectly named under ppt/media and also in slides/slide1.xml but correctly in ppt/slides/_rels/slide1.xml.rels - no wonder it does not work.

Dear Kevin Suo,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
 
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat: https://web.libera.chat/?settings=#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
