I would even settle for embedded, but it is not working in my case, using either MediaAudio1 or 2. Sad but true. Maybe I can dig up some documentation somewhere, since WMP is able to do the trick with either embedded and separate art.

Meanwhile, is it possible to implement some improved timestamp handling? E.g. whenever I transfer files from the player to local HD, timestamp always becomes 01-01-1980. The date/time of the start of transfer would be preferable in this case. This is of course only needed if the device does not handle datetime properly. Same goes for transferring jpg's from a camera. Is it possible to set datetime to the exif datetime? As I said in a previous post, this would lead to a full replacement of the outdated WIACam / CanonCam plugins.

Regards, EricB

When connecting Android 4.0 ICS over MTP, I can see both storage locations, but folders are shown as files (except .android_secure) and nothing can be opened (error)

UPDATE: This might be an issue of unstable ICS implementation, please ignore this bugreport unless confirmed. Thank you for your understanding.[/u]

I have the same issue with Android 4.0 and the new plugin. If I use Total Commander 7.50 with the old version of the MTP plugin (which does not rely on WMP), I have no problems and I have much faster transfer rates compared to using the Windows Explorer for MTP.

I am a little concerned that the new implementation will not be as fast if it uses WMP. The old custom implementation of the protocol seemed to be much fast than anything I have seen.

It's not a custom implementation, it was just the older 32-bit only protocol. Unfortunately Microsoft didn't port it to 64-bit, so I had to switch to the new protocol.

I do not see any speed difference here between the old and the new protocol with my devices. I'm using the buffer size recommended by the protocol for transfers. Maybe using a larger buffer size may help.

Ok, i see. The old implementation seemed to be better. Perhaps it is indeed some kind of bug with Android 4.0, but it is interesting that the old implementation seems to work MUCH better without any errors. I would not pay to much attention to speed if it is unstable with the new protocol.

Wouldn't it be possible to use some library for MTP to be indepedant from Microsoft? For example libmtp? Then again perhaps GPL might be a problem for the plugin.

If you use a Galaxy Nexus with the v2 plugin, then you will have massive problems. Files and folders are missing, some folders are shown as files with no content etc. With the old plugin, everything is working perfectly fine.

I do not know the problem. This is the same issue as described by Aleq. Perhaps it is related to Android 4.0, but the old plugin works very well for me.

Sorry, can't help you - just use the old plugin. This plugin is meant for media players, not for tablets.

It is a phone, which is used as media player by many people. I think Android devices are going to be the primary devices that use MTP in the future. However, I think that it is possible that your code is using Microsofts protocol absolutely correctly and the problem is an incompatibility, which is not your fault. Unfortunately, the old plugin only seems to work with 7.50. Anyway, thanks and keep up the good work.

Maybe it helps to update the Samsung KIES software. It should also update the driver.

Got 2 errors today when using TC to empty my digital camera, video camera and smartphone...

Did some investigation and come to these 2 senario's.

1. With NO media device present:
a. enter WPD2 plugin (no subfolder will be present, as nothing is connected)
b leave te WPD2 plugin again (without having done something)
c. use command "CM_unloadpolugins"
d. click outside of TC (eg on Windows-bar)

Application Error
---------------------------
Exception EAccessViolation in module TOTALCMD.EXE at 03320EC4.
Access violation at address 037220F0. Read of address 037220F0.
---------------------------
OK
---------------------------

Doing the same (except step d: try to reenter the plugin) with a MediaDevice present gives a the following error:

---------------------------
Total Commander 7.56a

I don't think many people use the cm_unloadplugins so probably not really important. I did because I wanted to update the WPD plugin to the latest version (and it was already loaded and thus the file was blocked). This is the result. But crashing of TC is worth mentioning...I thought....

Thanks, I will try to reproduce it.

Christian,

I've made a trace using WPDMon (from the MTP Porting Kit) while transferring a single music file without embedded art using the Creative software to the Zen player. This file shows album art while playing. Is this of any use for debugging?
The music file was first added to the library of the Creative software and it then also showed album art in the library, which means that the folder.jpg in the original music source folder was somehow picked up. Then the file was synced to the player using the software while running wpdmon both monitoring API and PnP traffic.

Regards, EricB
