Video files not syncing over wifi

[Theorize5643]

Hello,

I am experiencing trouble when syncing Media Monkey from windows to Android. Here is what I know and tried:

- My Wi-Fi connection is the same as the laptop
- The syncing process starts and I can see the progress.
- When the process arrives at a video, there is no progress on the lower progress bar for a couple of seconds, and then the whole progress advances to the next file.
- After syncing, the video files are not synced, they are just skipped.
- I use the paid version 2.0.0.1173 on a Galaxy S10 edge
- On my laptop I use version 5.0.5.2695 portable edition.
- The whole media library is stored on my NAS. I can go to the video's that won't sync and play them from Windows Explorer.
- The video files are MP4 or m4v types of files and most of them are in between 100-300 Mb
- I tried syncing using an usb cable, but this is even more problematic: in 9 out of 10 times it stalls, it tries to delete dozens of files despite that there is only 1 file changed. That is why I decided to pay for the android version.
- I have turned off VPN on both android and laptop.
- I tried to delete all files and resync, but this did not help.
- I connected my phone via an usb cable and copied the files with Windows explorer. Then synced, but this did not make the files appear in MMA.
- In MMW when I open properties, I do not get the message that the video files are inaccessible.

Does anyone have a suggestion of what I can attempt to fix this? Any assistance is appreciated.

Do the video files play in MediaMonkey itself?

This may be due to Auto-Conversion and maybe needing more codecs to do this. Can you try with the MediaMonkey Codec Pack? Does it still fail? If so, please try the latest MediaMonkey 2024 beta.

Thanks for the response.

The videos play without a problem in MMW.

Under Sync profile → Auto conversion, I have not checked any option. And at compatible video formats, I have added the video formats of the video I am trying to sync and indicated the phone can handle these formats.

I will try the codec pack this evening. However, when it does work and the files are synced, they play on my phone without trouble. For example, I already watched half of one course. And when I troubleshooted the syncing issues, I deleted all the video's of this course. Now it does not want to sync anymore (Wi-Fi and usb).

Additional information: I tried several usb cables because I read somewhere that this could also be an issue.

[Theorize5643]

Additional information: an hour ago, the usb syncing finished (without any error message). Because of the number of files (± 700) synced to my device, I assume that all files are overwritten, despite that only 20 or so should be new and therefore synced from MMW to MMA. It took several hours to overwrite the files that were already there.

However, when I look in MMA none of the new files show up in the app. So here is what I did:
- Went to the folders wheren the files should be via a filemanager → I see all files are on my device.
- Using Settings → Library & Sync → Check for new /changed media → No effect
- Deleted cache of MMA → Check for new /changed media → no effect
- Force stop MMA → restart MMA → Check for new /changed media (now the app shows it is scanning the folders) → no effect

What else can I do?

Did you ever try it with the MediaMonkey Codec Pack?

I duno... just a shot, but perhaps rebuilding the database will work.

It seems I have found out what takes the USB sync so long: the files are first converted or copied to a temporary folder. And then they are or are not transfered to the device.

At some point, I noticed that my drive was filling up. When I tried to find out why several Gb were added to my drive, I found out that in a subfolder of D:\Portable Apps\PortableApps\MediaMonkey 5\Portable\Temp\Transcoded_Media_Files several Gb were added. I deleted the temp files, and today I tried to sync using USB. I started shortly before 13:00 and then looked in the folder and saw that a subfolder was created: D:\Portable Apps\PortableApps\MediaMonkey 5\Portable\Temp\Transcoded_Media_Files\Device_3d109b4e-0380-304c-9c13-0f377c4a2807.1.4ed58d11-bc65-4951-8442-8528eebd10f5

This folder now contains 24 MP4 video files with the time ranging from 13:05 to 13:45. They are the video files that do not transferred to my phone. The only difference between the original and these temporary files is that the files in the temporary map are renamed to 39483.mp4 until 39506.mp4. The original files are also MP4 files and reside on my NAS.

In the settings, I have unchecked every checkbox in the Sync Profile → Auto-conversion section. And I have checked that all MP4 files are supported on my device.

So it appears that the video files are copied from the NAS to the temp folder on my laptop, then they are not copied to the phone. The syncing by MMW takes several times more than just manually copying the files from the NAS directly to the device using Windows Explorer.

It is possible to copy the original files from the folder to the correct folder on my device in no more than 15 minutes (about 10–20% of the time MMW took to complete a sync without actually transferring the files). There are no error messages, delays, or hiccups of any kind. But during the next sync, MMA did not recognize them and deleted the files.

The problems with syncing files are driving me crazy. In the past, I have tried a ticket to get support, but that was disappointing and frustrating as well. Does anyone know how I can set up MMW, so files are transferred directly to the device? Or at least make the manually copied files accessible until I have watched/listened to them. Many thanks for the help!

Hi,
I just tried doing WiFi Sync of MP4 files and they transferred correct to phone without conversion.

There must be something in your settings that makes things harder for MM.

File Naming is OK as it corresponds to Track ID in MM library.

What happens if you delete those cached files and try to sync again?
Are you able to play those files using MMA UPnP?

I have not sure if I have seen your ticket (please provide ticket number), but if you can start sync on smaller bunch of tracks while creating debug log https://www.mediamonkey.com/forum/viewt ... 30&t=86643 it would clearly show why MM is not sending the files to phone.

Sorry for frustration, but we are willing to get to bottom of the issue as that would benefit both and possible others if we find the cause of the issue.

Is Volume Leveling enabled in the Sync Settings?

[Theorize5643]

Please excuse the delayed response, I was on a trip abroad and was unable to test things because my files are on a NAS.

I will get all the information. This is what I do:

I make sure my laptop and phone are on the same Wi-Fi network. VPN is turned off on both devices. I can access (play) the files that are giving me trouble on my NAS via Windows Explorer. I can play these videos with any problems in VLC. Furthermore, in MMW I can open these files and play them in this way and I can open properties for these files and see not issues here. The level volume when syncing audio is unchecked. The cache is empty before I start the sync over Wi-Fi.

Here are my settings:
https://ibb.co/kgMHGbj
https://ibb.co/pyHfk7q
https://ibb.co/QjS6q7k
https://ibb.co/QjS6q7k
https://ibb.co/LC99dnp
https://ibb.co/6NYmH3B
https://ibb.co/MC4bry6
https://ibb.co/k2ZbFZz
https://ibb.co/3rnx02X

After the sync starts, I see in MMA that less than 10 files are deleted and 34 files are starting to download. The upper progress bar goes from 0 to 34, but each file in the album 'Fundamentals of Photography *' is not copied. Each file, there is about 20 seconds where nothing happens on the lower progress bar, and it stays on 0% before continuing to the next file.

Meanwhile, on my laptop I see that in folder D:\Portable Apps\PortableApps\MediaMonkey 5\Portable\Temp\Transcoded_Media_Files\Device_3d109b4e-0380-304c-9c13-0f377c4a2807.1.4ed58d11-bc65-4951-8442-8528eebd10f5 video files are copied. These are playable and there is nothing wrong with them. None of these files in the album copy to my Galaxy S10.

Then item 28 in the list is from a different album and the same applies. But files 28-34 are files from an album that is already partially on my phone. The first 30 files of this album are already synced. But I do not know if this was via USB or Wi-Fi.

However, on my laptop, the cache folder still fills up with new files of the album Fundamentals of Photography *. Even after MMA shows the syncing has stopped in the cache folder on the laptop, more files are copied. Moreover, these files are not deleted automatically and stay there until I delete them manually.

The files not synced are video files between 95 MB and 345 MB. Here are the details of one of these files: https://ibb.co/0ncRgbT

When I start the sync again (without deleting the cache) the files are copied again to the cache and replaced.

When I copy one of these files via X-plore FTP server to a folder on my Galaxy S10, I can play the file.

Syncing via USB takes ages and has the same result.

Hopefully, you can help me to pinpoint the problem. Is there anything you would like me to investigate or provide you with information? Thanks for the help.

[Peke]

Here are the details of one of these files: https://ibb.co/0ncRgbT

Can you make screenshot of Video File info (showing both audio and Video codecs details) in VLC (Windows) and in MM 2024 Details tab of same video file?

When I copy one of these files via X-plore FTP server to a folder on my Galaxy S10, I can play the file.

They play in MMA or VLC on Phone?

[Theorize5643]

The file on my Galaxy S10 works in both VLC and MediaMonkey.

Saturday I can provide you more information about the file because I can access the NAS. In the meanwhile, I have been watching a few videos that were already synced somewhere in the past. I want to see what happens with these files and the new ones that should be synced to replace the ones I watched.

I will keep you posted.

Here are the screenshots with file information you requested:

VLC:


MediaMonkey


The last 2 weeks I watched several videos on my phone and synced today. None of the video's synced over to my phone. There are now 40 files not synced, so the problem is not limited to this album only. The issue seems to be that all video files are not synced over Wi-Fi.

As far as I understand, there are three hardware devices involved, and they are connected as follows: NAS → cable → Laptop → Wi-Fi → phone.
The files are copied to a temporary under \Temp\Transcoded_Media_Files\ so that means there are no difficulties copying the files from the NAS to the laptop.

The music files are synced to the device, which suggests that there is no problem connecting between the laptop and phone over Wi-Fi.

The video files can be played on the NAS, laptop and phone. Which suggests there are no difficulties with the codec. Even if there were, why does that prevent the files to being copied to the phone?

What I do notice there is a lag between the progress on the phone and the files in the temp folder. On average, there is a lag of about 5 files. For example, when the progress on the phone during sync indicates it is trying to copy the 10th file, on the laptop in the temp file there are only 5 files. Can it be that there is a problem with timeout? That the software attempts to sync a file that did not have the opportunity to get properly copied to the laptop? Might sound crazy, but this seems the only explanation I can find. And would explain why only large files (video's) are not synced.

[Theorize5643]

I tried to test my hypothesis by doing this:

1. I copied 4 video files of the album that would not sync from the NAS to a temp folder on my laptop.
2. Added these files to MMW and added TEST in front of the album name and filenames.
3. Created a fixed playlist and added these 4 files to it.
4. Copied and renamed the AutoPlaylist that referred to the problematic files and changed it to use unplayed files from the fixed playlist I just created.
5. Unchecked the problematic AutoPlaylist and added the test AutoPlaylist.
6. Synced: all files from the problematic AutoPlaylist where deleted on my phone and the new TEST files where successfully synced to my phone.
7. Checked my phone and everything was as designed: the files show up on my phone under video and I can play them on my phone.
8. After this, I unchecked the TEST AutoPlaylist and checked the previous AutoPlaylist with courses on photography. In other words, I went back to the old situation.
9. When syncing, the test video files were deleted on my phone and the new video files (located initially on the NAS but copied to the temp folder during the process) failed to get synced to the phone again.

My conclusion is there is a concern transferring larger files from the laptop to the phone. The time it takes to copy a file from the NAS to the laptop is an issue here. The software looks for a file that is not there yet.

My video courses are too big to store on my laptop, so this is not an option.

What do you think? Is there a way to wait longer, so the file has been fully copied, before giving up on transferring files?

Did you send in a debug log (step 4b) of this as requested above?
