Transcode probrem and setting.

Hello,
Without changing the profile, not be able to change the file format to be converted?

and Suddenly I stopped the video in streaming. How do I?

conversion of h264 is because very slow. if possible mpeg2. When is lossless, the video is interrupted.

Please let us know:

• The device you are streaming to (including model number)
• The device profile assigned to your device. Go to the Media Devices dialog to see this.
• The FFmpeg information for a video that you are trying to stream. Right-click on the video in Mezzmo and click 'Get FFmpeg Information'.

Thanks for the information. Using the "Toshiba TV (2013 models)" device profile, this file will be transcoded to a compatible format for your TV.

The original file has a very high video bitrate (40Mb/sec) so it will take quite a long time to transcode and transcoding on-the-fly will probably be too slow for real time playback. I suggest you pre-transcode the video before streaming it and then it should play better on your TV. See this FAQ for details about pre-transcoding - http://forum.conceiva.com/showthread...nscoding-Files. Briefly, to pre-transcode your video for your TV, right-click on the video in Mezzmo and click 'Pre-transcode Files'. On the Pre-transcode Files dialog, select your Toshiba TV and click 'Choose Formats'. On the Transcoding Formats dialog, select the bolded format and click OK. Click OK to start transcoding and wait until it has completed. When completed, try streaming the video now to your TV.

If the video still stutters or does not play smoothly, then you can try reducing the video bitrate. To do this, go to the Media Devices dialog and edit your Toshiba TV device. On the Device Settings dialog, go to the Performance tab and move the Video bitrate slider halfway. Next, go to the Transcoding tab and delete transcoded files. Now pre-transcode the video again using the above steps. When transcoding has completed, try streaming it to see the results. Let us know how you go.

thank you.

By the way, whether this software and Android ver Mezzmo is compatible with Http Live Streaming(HLS)? Interruption well to being viewed on the wireless LAN (wireless LAN is 5Ghz, 11ac).

[Paul]

The current version of Mezzmo (v4.1.2.0) does not use HLS for streaming your files since not many DLNA / UPnP devices accept HLS when DLNA / UPnP media streaming. However, it is a technology we will look at implementing in the future as its adoption continues to grow.

If your Toshiba TV and PC are connected via wireless LAN, then this can also be a cause of stuttering when playing videos - especially high video bitrate videos. Make sure you have excellent signal strength to ensure optimal streaming bandwidth. See this FAQ for reasons for stuttering/buffering/stopping - http://forum.conceiva.com/showthread...reaming-videos.

Device configuration, performance, but there is a knob of video bit rate, this is not working? What will change?

The Video bitrate slider on the Device Settings dialog (Performance tab) lets you reduce the video bitrate when videos are transcoded. I suggest moving it halfway (like above) and then transcoding your video to see the effect. It should produce transcoded files with lesser video bitrates and these may play better on your devices and (wireless) home network.

I tried to move but encoding speed is no dramatic change?

[Paul]

I tried to move but encoding speed is no dramatic change?

That could be true. The transcoding speed may be slow since transcoding has to first decode your 1080p HD video that has 40Mb/sec video bitrate. It will require a lot of CPU processing to do this step.
