Title: Bitstream error
Post by: ex0dus on January 30, 2010, 07:48:07 PM
I can't play HD content anymore. mpg, m2ts, they won't play anymore.
I just upgraded to 2.02, but this didn't solve the problem.
Firmware 2.0 also won't play HD content.
Some time ago it worked OK, and all content played correctly, also with firmware 2.0
Nothing changed since then, what could be the problem?

All the content is streamed from the network from a Windows 7 PC, but before everything was playing correctly.
My mede8er doens't have a hard drive.

On my PC everything is playing the correct content, didn't have any problems with it (before).

/edit
mkv and wmv are playing OK.

Some example files, which played OK before:

Code: [Select]
Video: MPG2 1920x800 23.98fps [Video]
Audio: Dolby AC3 48000Hz 6ch [Audio]

Code: [Select]
Video: MPG2 1280x694 23.98fps [Video]
Audio: Dolby AC3 48000Hz 6ch [Audio]

Code: [Select]
Video: MPEG4 Video (H264) 1920x1080 23.98fps [Video]
Audio: Dolby AC3 48000Hz 6ch [Audio]

I have uploaded the mpg file (bbtf1985) to the FTP server, the file is shrinked, but it doens't play either.
On my PC it plays perfect.

Hi ex0dus

Your sample file "Back.to.the.Future.1.(1985).mpg" plays perfectly over my Samba network with V2.0.2.

Hi Ex0dus,

Have you also tried to play the file directly from a usb flash disc on your Mede8er?
Do you have then also the same trouble?

Please try to verify that your mede8er is running ok. when playing it locally and not over the network.

Hmm weird... I will try to play from USB stick, will keep you posted. ;)

/edit
Plays perfectly from USB stick! Weird... What could it be?

I am going to reboot my router and server...

/edit
Doesn't work either...

On another Windows 7 PC the file played correctly.
I changed some registry settings as described: http://www.mede8erforum.com/index.php?topic=64.0
Because without the registry settings it won't work (didn't see the share at all)...

So it has something to do with that partically Windows 7 PC.

I also modified the installed updates pictures, press CTRL+R. ;)

I have uninstalled the latest updates, didn't work either.

Hi ex0dus,

This will be difficult to pin-point to the root cause....

Some suggestions:
- try to disable firewall on your PC an verify again
- try to disable QoS packet planner in your network interface options menu and try again
- try to re-install the driver of you network interface card in your PC to latest version available

Uninstalling latest installed programs didn't work either.
Also the file says (when pressing info), (filename) @ 440167164

What does it mean?
Title: Re: Bitstream error

- try to disable firewall on your PC an verify again

* Firewall already was turned off

- try to disable QoS packet planner in your network interface options menu and try again

* Didn't solve the problem

- try to re-install the driver of you network interface card in your PC to latest version available

* I recently updated the Intel drivers (Intel INF),maybe it has something to do with it, but on the other PC, these drivers also are installed, and no problems with playing HD content from this PC.
I uninstalled the (newer) network card driver, and installed an older one, didn't solve the problem.

Weird thing is, only mpg and m2ts files are affected... Other files are playing OK.

After some Googling other users also have problems like this, only other brands (AC Ryan, Asus), didn't find a solution unfortunately.

Reverting back to firmware 1.22a did solve the problem, although I could play the content with 2.0...

So what's next? :P

Already did the emergency recovery procedure a thousand times...

Hi ex0dus,

We missed something in the troubleshooting discussion....
Do you have an internal disk installed in your mede8er?

If not, better stay on 1.2.2a and wait until a new FW is being released.
The current 2.0.x versions have instability when no internal disk, see the release notes....

So maybe this symptom you see is one of the issues....
Title: Re: Bitstream error
Post by: ex0dus on January 31, 2010, 10:51:18 AM
Maybe I didn't mentioned it, but no, there's no disk installed.
But as I said, the content DID play with 2.0... Without a disk installed.

The only thing why I need 2.0 or newer, is playing a DVD content folder, without having to choose the right file to play...
Except for that, 1.22a works OK for me...
Title: Re: Bitstream error
Post by: Maasbommel on January 31, 2010, 10:52:30 AM
You could do some verification and now upgrade again to 2.0.0 and see if it then is still running...
Title: Re: Bitstream error
Post by: ex0dus on January 31, 2010, 10:59:43 AM
Re-flasing again to 2.0.0 didn't solve it, don't know why.
I'm hoping for a far better firmware... Did have some very annoying problems with the mede8er unfortunately.
I just want to play the content, and not even more than that...
Maybe it's a idea to focus on just playing the content, than focusing on implanting a lot of un-useful features (maybe useful to others).

Maybe there's a "bare" firmware, just for playing the "stuff"? Don't need FTP, NAS or other things...

Or maybe there's a something tweaked 1.22a firmware, playing all content, but also plays a DVD folder in a simple way?
Title: Re: Bitstream error
Post by: Maasbommel on January 31, 2010, 11:09:59 AM
As far as I know the Play folder functionality comes with the 2.0.x versions of firmware and that has the problem that it can give some instability with no HDD installed as described in the release notes.
The play folder comes from the used Realtek SDK in the 2.0.x version and that has the HDD issue also, so only thing mede8er can do is wait for a fix from Realtek for that.

I know that mede8er is really pushing and working hard to get a new version out to fix the 2.0.x issues, so only thing we can do is to have a little patience. It will come....

Please provide a photo of this - I have never heard of this before.

With respect to running the v2.0.x firmware without a hard drive, there are very clear and specific instructions on the download page not to use that version unless your HDD setup allows for it. Mede8er techs are working on a solution for this which is being tested. Another instruction was to remove power from the Mede8er after installation to bed down the firmware - perhaps you didn't do that either after installing until later, during which you were able to play the file successfully. The new firmware introduced some bugs which are currently being dealt with before new development can continue. These bugs are specific to Mede8ers that don't have internal HDDs or the HDD is not formatted in the Mede8er.

There is no 'bare firmware' but the problem doesn't appear to be in the firmware as your other PC's share works - there is something wrong with either the hardware or settings on your one PC.

For now, stick to firmware v1.2.2a and focus on the settings on your problematic PC share. To my understanding the problem is clearly not with the Mede8er firmware if the file plays fine on another PC share. Try removing the share entirely and recreating it - configure the permissions again and force the child files and folders to inherit the permissions of the parent folder.

Kindly provide your setup details in your sig as suggested in the technical sticky - not having these details and having to search through all your posts for details is prohibitive to providing support.

But this doesn't explain why just the mpg and mt2s files do not play, HD WMV and MKV are playing OK.
It's kinda weird. Why just these files? And why are they playing from another PC correctly? What can go wrong with just these filetypes?
Title: Re: Bitstream error
Post by: Insomniac on January 31, 2010, 03:18:09 PM
I'm assuming it requires the internal swap partition for caching of certain material to assist with buffering - not really sure...

Why is it different for different file formats? - I've no idea what the Realtek devs had in mind here...

Either way this is a known bug that the devs are currently focused on resolving.

The truth is this is actually too sad that someone decided to make this change expecting everyone to have a formatted HDD - unfortunately this wasn't tested without a HDD as Realtek don't provide changelogs of the SDK.

Post by: ex0dus on January 31, 2010, 03:36:56 PM
Yeah, but why do the files play from a different PC with the same OS?
Well I hope it can be fixed in a future firmware update. For now i'm out of ideas...

About 2 weeks ago I played a HD movie, which plays correctly.
After that I did some things:
- Installed updates (but removed them already)
- Changed the root HDD for a differtent disk (cloned it), old one had bad sectors
- Changed the disk where the movies are stored on (from 2 x HDD in RAID to a single one)
- Installed the new Intel INF drivers
- Installed XAMPP (Apache etc)

After that...
- Removed the updates
- Installed an older network driver
- removed all programs installed in the last 2 weeks (just two)
- Made new shares, removed old ones, changing to same shares again
- Paging file off and on
- "Turn off Windows write-cache buffer" on HDD on and off and on again
- Rebooted the server a thousand times
- Made several changes to network adapter, TCP/IP 6 on and off, QOS on and off
- Turned firewall off and on
- Windows defender on and off
- Copied HD files to different share/disk/partition

But with a internal hard drive it should work? I could try that, not now, but tomorrow.

Finding the root cause with this amount of changes you did the same time, it will be a painfull process to find.
 :P
Title: Re: Bitstream error
Post by: ex0dus on January 31, 2010, 04:08:29 PM
Not really the same time, but it has been a week or two, after that I did some changes, yes. But nothing with the OS itself.

Also it has some extra things to it, it's got Kerio mailserver, Apache, MySQL, FTP etc, but it used to stream everything.

It also could be Kerio, you never know... What port is used for mede8er to connect to share?
From other PC's i can access the share with no problems, but maybe the mede8er uses a different method?

/edit
With Twonkymedia, mpg and m2ts are playing correctly. But that's not really a solution. :(
Title: Re: Bitstream error
Post by: ex0dus on January 31, 2010, 05:34:07 PM
Breaktrough, when stoping Kerio mailserver, every file is playing correctly... ??? ???

/edit
Runned some tests.
Kerio runs on port 444 for connecting Outlook to the server. Standard port was 443, but it was in use, couldn't figure it out which program, so i changed it and everything was working fine.
Port 444 is used for this: http://www.iss.net/security_center/advice/Exploits/Ports/444/default.htm

So I changed it to another port number.
I restarted Kerio, but files won't play again.

(http://cimpelserver.cimpel.nl/images/mede8er/kerio.png)

These are the portnumbers used... Is there something wrong with it?

Using port 12246 instead of 444, won't work either.

/edit
Stopping service on port 8080 seems to solve the problem...

/edit
Changing portnumber 8080 to 8090 seems to solve the problem so far... Has port 8080 something to do with the mede8er playing mpg or m2ts??

Confirm this.
When a file cannot be played and you get a Message "Bitstream-Error" press info before the message pops up and you see this  (filename) @ 440167164

Reproduce:
Run a service like apache on port 8080 on your serving machine and play a .m2ts from it -> gives Bitstream error. (as exodus figured out)
