First Install Thumbnails issue

[Fred From Lyon]

Hello all,

First excuse me for my English, i'm french.
I installed yesterday Mezzmo because i have difficulties with Samsung PC Share Manager and PS3 Media Player.

No problem during installation, everything worked fine even with zonealarm. My Samsung LE40C630 TV was recognized instantly. :). It is designed as samsung C device.

The library scan was launched for a long time for my 20 000 pictures (JPG + DNG) but not so much movies.

When i first launched mezzmo on my TV, it was impossible to browse folders because scan was running. At the end i was able to browse movies, pictures very easilly and relativly fast. The thumbnails were ok.

On the next start, i had trouble with thumbnails. The thumbnails of my movies were those from my pictures ??? whereas the thumbnails of my pictures were ok.

Mezzmo looks like a very very good software, i plane to by it if he did the job and for the moment it's the case. Moreover, the price is very decent.

Just anaother thing, during scan i get a lot of ffmpeg fatal errors. The only thing to do was to click "OK".

Another simple question : How do we know when reencoding is on ?
is it possible to display DNG files ?

Thank you for answer.
Probably mezzmo another client.

Configuration :
PC With XP pro SP3
2 Gb RAM
E8600
Wired conncetion to TV across a 100mb switch
Samsung TV LE40C630 with last firmware update.

Hello,


On the next start, i had trouble with thumbnails. The thumbnails of my movies were those from my pictures ??? whereas the thumbnails of my pictures were ok.

If you look at your movie files in Mezzmo's GUI (not on your TV), are the thumbnails ok?



Just anaother thing, during scan i get a lot of ffmpeg fatal errors. The only thing to do was to click "OK".

We have an updated build of FFmpeg that doesn't show errors, if you wish, please send a message to support (at) conceiva (dot) com and we'll send you a copy of that to replace yours.



Another simple question : How do we know when reencoding is on ?

At the moment the only way to know if transcoding is happening or not is to check the Task Manager for presence of "ffmpeg.exe" - if it's there, then most probably Mezzmo is transcoding that file. Future versions will provide feedback about this in the Status pane.



is it possible to display DNG files ?

Not at the moment, but I'll add a note to investigate this format.

In the Mezzmo GUI i can see wrong thumbnails. Movies thumbnails are those from the pictures as i can see on my TV.
Should i update my movies folder with the new ffmpeg to get right thumbnails ?

Photos thumbnails seems to be correct.

i use version 2.1.11 (the version of the trial download link), may be i have to update my version ?

The mail to get updated version of ffmpeg is sent.

thanks

I have updated videos using icon "maintenance bibliothèque" and now thumbnails are "ok".
Few minutes ago i tried to watch movies dones with Camera Canon powershot G7. It's AVI container with MJPEG (motion JPEG) codec Video and Signed 16 bits little endian PCM codec audio. Each 5 seconds the movie stops and i have to wait 10 seconds to watch the following.

Any idea about how to correct this problem ?

Moreover, i can't play this movie, my TV says unknown codec, here's mediainfo description :

i can't understand why ?

I have updated videos using icon "maintenance bibliothèque" and now thumbnails are "ok".

Ok, so it works now? Strange that the thumbnails didn't appear the first time.

Most probably it's transcoding. If you try to play it from the start after a few minutes, does it play ok?



Moreover, i can't play this movie, my TV says unknown codec, here's mediainfo description :

Can you please post FFmpeg information on that file (in Mezzmo right-click on the file and use the "Get FFmpeg Information" command).

Are you using the "Samsung C" device profile?

[Fred From Lyon]

Yes, actually thumbnails are the right one. Viewing pictures in TV is very nice, mezzmo is a great software, the best one for pictures.

For my "special" divx, i can't play it even 10-20 muinutes after start. When i launch the movie i have the icon wait and then the TV displays unknown video codec. It's the same thing with samsung pc share manager. It's not a great problem, if there is no solution, i will reencode this file with SUPER.

I'll post you soon ffmpeg info.

I use samsung c profile.

thanks

[Fred From Lyon]

Hi,

I sent you by mail ffmpeg report about 2 files.
- The fist one about a avi file that is not playable with mezzmo, the tv says unknown codec.
- The second one for video from camera (Canon G7). These files are displayed 5-10 seconds before mezzmo send the next one for 5-10 s too and so on.

is it possible in mezzmo to tell the program that this file (known has been unsuppoted) should be transcoded or is it the files extension who is the ultime criteria ?

Thanks

[Paul]

Hi,

Thanks for the file info - I'll get back to you via e-mail regarding that.

Mezzmo doesn't look at file extensions to determine whether a file is playable or not - we dig inside the file and get the actual video/audio codecs and match them with what the device supports (or doesn't) to determine whether the file needs transcoding or not.

[Fred From Lyon]

Ok, thank's, i'm waiting for the answer.
With the new ffmpeg there are no more fatal errors when scanning folders for update.

Another question, is it possible to have all file in normal folder to be streamed and in the same time all files too in transcode folder ?
With this, if a file is not playable directly, you can go to the transcode folder to display it correctly. Or is it possible to force transcode for file who are normally playable but drive to an error, regardless container, video and audio codec ? In fact in the library can we say this file will be transcoded ?

Is the getprotocolinfo an interesting information ?
Do you need other informations such as samsungdesc.xml or RemoteUIServerDescLevel1.xml or PersonalMessageReceiver.xml ?

Thank's.

[Paul]

A future version of Mezzmo will show you which files need to be transcoded and you could also force transcoding on files as well - this should be part of the next major update, I believe.

Yes, GetProtocolInfo is always interesting :) SamsungDesc.xml can also help - the other two XMLs are not related to the way Mezzmo operates, so probably nothing useful in them.

[Fred From Lyon]

Hello,

You said in your mail about my second file, the one done with canon G7 Camera that “The second file is transcoded and there are several reasons for it to skip.”
So the problem comes from transcoding and I know that this format is supported by the TV because Samsung PC Share can play this king of files like other software I have tested.

In the same time I watched samsungLA.prf. I think it’s the profile I use for my Samsung C serie. About the avi container, codec video mjpeg and codec audio pcm_s16le are not listed.
So I suppose that when codec are not listed files are transcoded ?

If it’s the case, maybe I could add theses lines in the samsungLA.prf in the container avi section line 140 : (encode =”0” means no encoding for selected codec).

<video>
<format id="mjpeg" encode="0">
</format>
</video>
<audio>
<format id=" pcm_s16le" encode="0">
</format>
</audio>

I guess these lines will match with the movies from my canon camera ?
Could it be a way to get these files playing well ?

For the second file (the first one in ffmpeg report) these lines are reported.
[mp3 @ 0167fac0] Header missing
[mpeg4 @ 0167f050] Invalid and inefficient vfw-avi packed B frames detected
Maybe the problem is here and the solution could be to modify these tags ?

Thank’s.

PS : I sent you SamsungDesc.xml.

[Paul]

Hello,

Yes, you can add those lines and if the file plays natively, please let us know and we'll add this to the official device profile as well.

Not sure about the second file at the moment, but the "header missing" doesn't sound promising, although it may be a minor thing.

[Fred From Lyon]

I tried to modifiy the prf file as describe before. The first file were played well and there was no ffmpeg process runnig. Then there was a succession of well played files and stopped ones. The files well played displayed total time the other don't. These files have exactly the same ffmpeg description.
So it looks like ffmpeg is running whithout knowing why ?
The software decides to transcode without taking care of prf settings.

[Paul]

Did you restart the server (using stop/start buttons) after making the change to the .prf? You need to restart the server for changes to take effect.

[Fred From Lyon]

I did this before launching the prgramm and he's not starting automatically.
Then i laucnhed Mezzmo. The way Mezzmo works in the case of my files is very strange.

thank's

[Fred From Lyon]

Hi,

I have restarted my computer after have modified prf setting file. Now, the movie who were bugging yesterday are now playing fine, the total time is displayed and ffmpeg is not starting. So it's working and i think you can add these settings in the official version. Samsung serie C TV seems to be compatible with mjpeg video whereas it is writtend in the manual of my TV that only Samsung techwin MJPEG is ok.

So my last problem is the other movie (700 mb one).

[Paul]

Ok, thanks for letting me know - I'll add that to the official device profile.
