Transcoding error

[Fuki]

Hi!

I cannot transcode anything any more. Today I tried to transcode several different file types but I keep getting status "Failed". This is an example of the error log (MezzmoFFmpegTranscodeFileLog.txt):

I was transcoding files normally before, without any errors.

I'm using the latest version of Mezzmo (5.0.5.0).

Can you please help me solve this problem?

Hi Tom,
it looks like QuickSync is being used and the QuickSync encoder is failing to initialize. You can try going to 'Transcoding Settings' in Mezzmo and turn off QuickSync encoding and this will allow you to transcode files again. If you have previously been able to use QuickSync for transcoding please check to make sure the Intel Media SDK is installed as this is required for using QuickSync, the Intel Media SDK is usually installed along with the drivers for your motherboard.

Hi Peter.

Yes, Transcoding Settings show that Intel Quick Sync is being used for transcoding. I've never really been aware of that.
I also don't know how can I disable it since it's greyed out and it cannot be uncheck.
Looking at Transcoding Settings I saw that ffmpeg version used by Mezzmo was rather old so I downloaded latest official 32 and 64-bit versions (Build date: 2016-10-02 23:20:10) and replaced the ones that came with Mezzmo.
After ffmpeg replacement I've tried transcoding again, but it didn't help.

Regarding Intel Media SDK, its never been installed on my computer so I don't know how transcoding was working up until now.
I wanted to download it from Intel (link (https://software.intel.com/en-us/media-sdk/download)) but Intel wants some personal data from me (before download) which I'm now thrilled about so I decided not to download it for now.

Is downloading Intel Media SDK really necessary?
How everything worked up until now?

Regards,
Tom

Hi Peter!

I just realized what is the problem, but I still don't know how to solve it.
I bought a discrete graphic card so I disabled Intel IGD.
This (https://www.asus.com/Graphics-Cards/R7250-1GD5-V2/) is my new graphic card.
Can you please help me now, when we know what is the source of the problem.
Tnx!

Best regards,
Tom

Hi Tom,
try going to C:\Users\<username>\AppData\Local\Conceiva\Mezzmo (where <username> is your username) and edit the file MezzmoMediaServer.ini then look for TranscodingUseQuickSync=1 and change it to TranscodingUseQuickSync=0 and this should disable Quick Sync and resolve the issue. The new graphics card does not have Quick Sync capabilities so it will need to be disabled.

[Fuki]

Tnx Peter!

This solved the problem!

Best regards,
Tom

Hi Peter.

Although Mezzmo is transcoding, burning subtitles does not work any more.
Everything looks fine in Mezzmo, but when streaming (transcoded) video to TV, there are no subtitles.
Could you please help me investigate and solve this problem?
Tnx!

Regards,
Tom

[Peter]

Hi Tom,
the ffmpeg that you have updated to does not contain the Mezzmo filter used to burn subtitles. The ffmpeg.exe included with the Mezzmo installation must be used to allow burning subtitles when transcoding, you can restore this version if you have overwritten it with the updated version by downloading the Mezzmo installer from our website and run it to replace the ffmpeg.exe with the original version.

[Fuki]

Tnx Peter!

Subtitles are back again. ;-)

Best regards,
Tom

Glad you are back up and running :).
