    Error after OK/Cancel/Close in camera settings dialog (empty file was created). Also tried without dialog - the same problem :

    



    [dshow @ 0715de40] Query for IPersistStream failed.
video=Microsoft® LifeCam Studio(TM): I/O error


    



    I assume that problem at the camera side, but I don't exclude my blindness (didn’t find any examples of saving settings or required command options in the documentation).

    



    Perhaps there is another way to save / load webcamera properties ?

  • How to embed cover art into MP4 without errors ?

    7 mai 2020, par symonxd

    I want to add artwork to my MP4 file. How do I do this successfully / without errors ?
I've tried these methods with numerous MP4 files, none worked.
If you would like to replicate the errors / bugs, here are the sample files I've used for this question.

    



    I've tried the following :

    



    


      

    1. ffmpeg -i sample.mp4 -i sample.png -map 0 -map 1 -c copy -disposition:v:0 attached_pic sample_w_artwork.mp4
as stated by Lukas

      2. 


    



    with this error :

    



    [mp4 @ 0000019ee4852280] Could not find tag for codec h264 in stream #0, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument


    



    ffmpeg 4.2.2 (Windows build by Zeranoe)

    



      

    1. atomicparsley sample.mp4 --artwork sample.png --overWrite

      2. 


    



    with no success ; AtomicParsley

    



    I get this message when executing the first time :

    



    Started writing to temp file.
 Progress: =============================================>100%|
 Finished writing to temp file.


    



    Executing the next (nth) time gives this :

    



    Updating metadata...   completed.


    



      

    1. Adding artwork through the GUI Tag Editor using both available versions : i686-w64 & x86_64-w64

      2. 


    



    with no success ; it creates a sample.mp4.bak file, even though the software says that the operation was successful

    



    


    can't insert any more links, because I got too little rep apparently

    


    



      

    1. Mp3tag (mp3tag.de/en)

      2. 


    



    with no success ; I can successfully add the image as a cover, but it's not visible in the File Explorer. After saving it says Saved tag in 1 of 1 files. The picture can been seen in Mp3tag though as if it's applied.

    



      

    1. Tag&Rename (softpointer.com)

      2. 


    



    with no success ; same story as with Mp3tag, I can apply and it's visible in the app, but not in File Explorer.

    



      

    1. mp4v2 (https:// code.google.com/archive/p/mp4v2/downloads)

      2. 


    



    mp4tags.exe -picture sample.png sample.mp4

    



    with no success ; it executes with no (error)message

    



    I found it on this thread

    



    (https:// forum.videohelp.com/threads/388025-How-to-set-the-thumbnail-of-a-video-clip).

    



    Have used the updated version which is the Windows build

    



    (https:// forum.doom9.org/attachment.php ?attachmentid=14314&d=1407985798).

    



      

    1. iTunes

      2. 


    



    iTunes 12.10.6.2 (Microsoft Store version)

    



    iTunes doesn't load the file into the library. I can run it fine though in QuickTime Player.

    



    I didn't notice the 'Home Videos' tab. Now I can see it in there. I tried to apply the image, and it applied it only inside iTunes... So it's still not working for me.

    



    I tried to convert the MP4 to M4A and then adding it to iTunes. I was finally successfully able to change the cover and it was visible in File Explorer. But that's not what I want.

    



    I know for a fact that it's possible, because I've seen pictures on the Internet and YT and different threads where an answer is upvoted.

    



      

    1. tag

      2. 


    



    https:// github.com/b4winckler/tag

    



    The description is : Simple command line audio tag editor... After having to install millions of libraries and a package manager I was stuck with the compilation of the software, followed all the steps, didn't work.

    



    I've also tried using MP4art as suggested by a comment on another issue about this. He didn't include a link to it so I went looking and found another issue about this. One comment recommended MP4art as well, with a link that's dead.

    



    



    I believe I've used some other methods as well but can't think of them right now. Will update if I recall.

    



    Any help is greatly appreciated.
