Panasonic TV transcoding problem (cpu 100%)

[freeman]

Hi,

i'm a Panasonic TX-P46GT30E owner and i'm using Mezzmo but i've some problem with transcoding. In fact when the process start the cpu usage jump to 100% and the streaming stuttering.

I've tried with others Panasonic profile, but the result is the same.

thank you for any kind of support.

I'm having the same problem with my L47E5E Panasonic. And the CPU is not that bad (beeing a E3 Quadcore (with HT) Xeon and 16GB RAM) - but transcoding just hits 100% cpu and is slow at ~20fps. Transcoding with other programs runs x times faster... I think it's the bundled and older ffmpeg version?!

Hi Freeman & JMC,

Please post the FFmpeg information for one of the videos that is transcoding too slow. Right-click on the video in Mezzmo and click 'Get FFmpeg Information'. Also let us know the device profile assigned to your TV. Go to the Media Devices dialog to see this.

Hi Paul,

sorry for my late... these are the ffmepg information, i prefere to include two examples, first about avi file and second about mkv.
The TV profile is "Panasonic TV (2011)"

Thank you for your support-

Up up up up!!

:)

[Paul]

Thanks for the FFmpeg information. Please email us at support [at] conceiva [dot] com and we'll provide an update device profile to try.

[JMC]

I can't test at the moment, but I would like to know if the profile fixed the Problem. Please report back here, too ;)

[Paul]

Update: We found that one of Freeman's AVI files was being transcoded when it actually was supported by his TV. So, we have adjusted the device profile to not transcode this type of AVI file. This will result in less transcoding & immediate playback. This device profile tweak will be included in the upcoming Mezzmo v4.0 - or can be obtained now by emailing us at support [at] conceiva [dot] com.

[JMC]

TBH - apart from a strange recording I did with Ngrab years ago everything else is supported by my TV - and Mezzmo wants to transcode 40% of it - i would say. But there a questions:

- There was also an aspectratiofix, is this included in the new profile?
- Honestly I can't understand why transcoding with mezzmo ffmpeg is so slow, machine as stated above should be able to do it faster.

Thanks
Peter

Hi Peter,

We are working on a few aspect ratio improvements at the moment. They will be included in the upcoming Mezzmo v4.0. This new version will also include a new 'ffmpeg.exe' (that is ised for audio and video transcoding) and it may improve your transcoding speed a little. Transcoding speed is partly dependent on your computer's performance - but is also dependent on the original video file's attributes (resolution, video bitrate, audio/video codecs, etc.) and what you are transcoding it to (resolution, video bitrate, audio/video codecs, etc.), For example, transcoding a HD 1080p MKV (h264, AC3) with 15Mb/sec video bitrate to another video format will require significant processing due to the enormous amount of video data to be converted/transcoded.

[g0rg0n]

I don't think your last reply address Peter's last statement. While I am happy there will be new adjustments to FFMPG in the future updates...I had to disable transcoding completely because 90% of my video library doesn't need transcoding to my PS3, yet Mezzmo insists on transcoding and then hogs 100% of my quadcore desktop processor, or my 8 core laptop processor.

There is something wrong with the transcode profiles shipped with your product that is telling it that a simple vanilla mp4 with aac needs to be transcoded. Since I just updated Mezzmo, and I keep seeing you say to people "email me for a new profile" i have to assume there is some guarded secret that you can't simply bundle the correct profiles with the program.

[Paul]

Hi g0rg0n,

We can improve the PS3 device profile so that you don't need to turn off transcoding. We need to know two things from you to do this:


The device profile that is assigned to your PS3. Go to the Media Devices dialog to see this.
The FFmpeg information for the files that will play without transcoding. Right-click on them in Mezzmo and click 'Get FFmpeg Information'. Provide a variety of different file formats that stream & play natively for you on your PS3 using Mezzmo server and we'll make sure the device profile does not transcode them.

Once we get this, we'll tweak the device profile for you to try.

There are no secrets regarding device profiles :confused:. The way it works is like this: We constantly are improving device profiles and they all are included in the latest version of Mezzmo that we release. Users always come to us with a particular file that does play or does not play and we tweak the related device profile to further improve it. The user tests the new device profile and if it works, then it is included in the new Mezzmo version for all users.
