    Also, I forgot to say that the error & crash logs I sent yesterday returned today, bounced. I've re-sent them.

    Cheers,

    Thanks again for your reply Paul.

    The emails just tell me to do what you told me to do (update). Since I couldn't do that I unistalled Mezzmo and re-installed from the website from scratch: no improvement, as noted above. I'll look again later this morning to see how we're getting on. (I also note that I'm getting the 'Too slow' warning again.)

    Cheers,

    Chris

    OK - after re-installing, please email us a new set of logs when the problem occurs & we'll check out what's going wrong. Regarding the "Too slow" warning in the Transcoding pane, please post the FFmpeg information for that video. Right-click on the video in Mezzmo and click 'Get FFmpeg Information'.

    Hi Paul - the FFmpeg for the transcoding file is massive, I hope it's right! This is currently transcoding - though I have not tried to view it - at a 2 fps.

    I also tried to get another (the 8 second video), just because it's short & shouldn't be any trouble for Mezzmo, but the FFmpeg files seems to be too short (like the first one I posted), but I assure you it was all Mezzmo produced!

    Hi Chris,

    Thanks for the information. It shows that your original video has a resolution of 1920x1080 and a high bitrate of 16Mbps - which is common for camcorder videos. Transcoding HD video with high bitrates like these require significant CPU performance, so I am not surprised that you are only getting 2fps transcoding speed. A few things to try:

    • Go to the Media Devices dialog and edit your device. On the Device Settings dialog, go to the Transcoding tab and turn off transcoding checkbox and delete your transcoded files. Restart your Mezzmo server and try streaming this file now. Mezzmo server will stream it directly to your TV without any transcoding. SO we want to know if your Tv can handle such a high bitrate. Does it play OK?
    • If the video did not play on your TV when streamed directly, then we know that your TV cannot play such high bitrate videos and you will have no choice but to pre-transcode these high-bitrate videos - as mentioned in my previous posts on this thread. Remember to turn back on the transcoding checkbox for your device.

    Thanks for this Paul - I'll turn off transcoding and see how we go.

    Cheers,

    Cool Progress!

    Ah - you're onto something Paul.

    I tried AVI, WAV & MOV files which did not work ('File not supported', or similar). I imagined this would be the case.

    However, when I tried the MTS (or MT2S - they seem to be identified alternately in different applications), they work splendidly! In fact, it was just as it used to be! The clarity is perfect, even the fast forward, etc. works perfectly. Happy days! (These files were produced by the Panasonic HD60 camera which we got hoping for maximum compatibility with our Panasonic Viera TV.)

    I also tried some MPEG2 videos - I can't remember which device produced them - but they also work (nearly) perfectly. The quality is not HD and the ratio seems to stretch from 4:3. I've read something about it here but I can't remember where now. (I prefer to maintain the original ratio.)

    This all emphasises my ignorance as I don’t understand what transcoding is. I thought this was the basic requirement of a media server so (I thought) that turning transcoding off would simply stop everything working. I have read a good deal in trying to get Mezzmo up and running (honest!) but this seems to have gone over my head.

    (For instance, our TV plays MTS files natively, but ONLY if they’re input from the SD card or connected directly to the camera. MTS/MT2S files copied directly from the SD card to anything else means the TV cannot read them – unless through Mezzmo, which I thought had to transcode them…)

    Anyway, we have progress here. I assume I can set transcoding for AVI, WAV & MOV (etc.?), but not for MTS/MT2S & MPEG2 (etc.?) – is that correct?

    The other question is, why am I having problems now, but previously Mezzmo worked without have to alter these transcoding settings? Has WHS 2011 bogged down my system that much? (I’m running an AMD Sempron 2.7Ghz processor/4GB RAM/Gigabyte wired network/SATA I & II.)

    Thanks again Paul (& Peter),

    Cheers,

    Chris

    Good testing, Chris. Please email us at support [at] conceiva [dot] com and we'll provide a device profile to better match the streaming capabilities of your TV. In your email, please include the FFmpeg information on a few of your MPEG2 videos that play perfectly with transcoding turned off.
