Hardware Acceleration

[davesiddons]

When do you expect to support hardware acceleration for transcoding (GPU). I have a quad core q6600 with 8mb of ram and it wont cut it so a bit disappointed

Mezzmo uses FFmpeg for transcoding, so once FFmpeg supports GPU accelerated encoding, Mezzmo will too.

Any idea on a timeframe for this.

I have trialed WMS too and that streams without problems at full speed (apparently usinf FFmpeg too). I prefer Mezzmo so have I configured something incorrectly. I am streaming to an IPAD. The FPS rate for transcode in mezzmo says 13fps and nothing displays on Ipad

For iPads, we recommend you use the Media Link Player Lite app. Make sure you have the device profile set to 'Alpha Systems Media Link Player Lite (iPad)'. Go to the Media Devices dialog to check/change your device profile.

If that does not help, please post the FFmpeg information for the file that you are trying to play. To do this, right-click on the file in Mezzmo and click 'Get FFmpeg Information'.

Tried all three media link player profiles and nothing plays on ipad or iphone (3rd gen and 4s). On iPad profile the videos show as incompatible format (even though the server is transcoding them. In the other two profiles (baseline and normal) file is listed as "may not playable". You try and you get either failed to launch movie player or url not found.

ffmpeg info for simple sample mkv below. WMV was other format tried.

Cheers

Please pre-transcode this file and see if it works on your iPad. Set the device profile to be 'Alpha Systems Media Link Player Lite (iPad)' again. Then, right-click on the file in Mezzmo and click 'Pre-transcode File'. In the Pre-transcode dialog, select your iPad and click Choose Formats. Select the bolded formats and click OK. Click OK to start the pre-transcoding. Go to the Transcoding pane in Mezzmo to view transcoding progress. Once the file has been fully transcoded, then you can use your iPad to connect to Mezzmo and try to play the MKV file. Does it play now? If yes, then this shows that file must be fully transcoded before streaming to your iPad. Let us know how it goes.
