    We have just uploaded an update of the Mezzmo Roku Beta with some changes:

    - Added a setting to turn on/off continuous play of videos (it is off by default)
    - Added support for manually adding a server using the ip address. You can use this to add your Mezzmo server to stream over the Internet to a Roku in another location.

    We also fixed a problem where if the URL to the server returned no data or invalid data it would crash the app and leave it on the 'loading...' page.

    You can update the existing beta to the new version by going to settings on the Roku then System then System Update and selecting Check Now.

    Hi Peter:

    I updated to version 1.4, build 3. The app still gets stuck at the "Loading..." screen. No server other than Mezzmo and Win10's DLNA are installed on the machine hosting Mezzmo. That computer's primary purpose is recording sports programming using NPVR and a Hauppauge Colossus. It is those video files I'm hoping to use the Mezzmo app on the Roku Premier+ to stream rather than the Sony Blu-Ray player I've used for several years.

    Going down the deductive path that maybe some other uPnP device is interfering with the Roku apps server lookup, I've taken of screen capture of the devices screen in Mezzmo so you can see all the media devices on my network. The devices I use (just a fraction of the total) for sharing files, network streaming, and internet streaming work as they did before I added the Roku. FYI, the clunky Roku DLNA app I downloaded from the Roku store can browse my Mezzmo and WHS2011 servers (the Roku can see them) - it just cannot play the HD formats I use (Hauppauge NPVR recordings, iTunes from the WHS). My primary means of streaming from Mezzmo to my TV is via has been the Sony Blu-ray. That hasn't changed -- and it's not affected by the presence of the new Roku. Given all this, it does seem that the app's server discovery is being interfered with as opposed to a hardware or network setup problem.

    If I could get the Roku app to load, I'd love to set it with a static IP (most of the shared devices on my network use a static IP) and hopefully not have to deal with the device discovery process! Thanks in advance for your help.

    We have made a change so that the search for servers is not performed by default when starting the app, this should enable you to get to the servers screen where the Refresh icon and '+' add icon are displayed. You can try using the Refresh icon to initiate the search to see if the server is found or you can select the '+' add icon to enter the ip address of the server to add it manually.

    Peter, that change allowed the app to see and I could select the Mezzmo server! I can browse and navigate through the folders. Now I have a new challenge to address: None of the videos play. When I press the play/pause button on the Roku remote (or my Harmony remote) to select and play a show, nothing happens. I get the deadpan beep and sometimes a partially filled progress bar flashes across the bottom of the screen. Also, I cannot scroll/navigate to the Play button in the upper right of the screen using the arrow buttons to attempt playback that way.

    I'll start researching what the Roku natively supports to ensure the .ts files produced by the Hauppauge Colossus are compatible. There's no sign (the transcoding window on the server is empty) that the server is trying to transcode the file.

    Peter, it looks like it is a file compatibility problem. I'll work on that first. If I need to remux or trancode each .ts file to a .mkv that Roku supports, I probably will just continue in almost every instance to use my Sony Blu-ray player to stream the shows recorded by the Hauppauge Colossus. I can use the Roku and the Mezzmo channel app to display photos and music stored on the servers.

    Your solution to add the search button, an add server button, and to display the connected Mezzmo servers on the lower left of the screen is a pretty elegant (and flexible) solution. Bravo! I didn't clearly say in the message above, but the app, once it loaded, had discovered my Mezzmo server and it displayed it as a third button next to the add button.

    Glad to hear the Roku app is working now and finding the Mezzmo server. For the issue with playing the .ts files can you please right-click on one of the files in Mezzmo then select 'Get FFmpeg Information...' and copy and paste it into a post here or send it to support [at] conceiva [dot] com so we can try to reproduce the problem here with a similar file?

    As a test I had Mezzmo pre-transcode one of the .ts files that wouldn't play on the Roku. Once transcoded using the recommended (bold) settings, the file played fine. The PQ wasn't really very good -- artifacts were easily visible. But it did get over the first hurdle - it successfully streamed to the TV via the Roku.

    Here is the ffmepg info for one of the files created by the Hauppauge Colossus that will not play from the Roku:

    I tried playing some similar files here and with transcoding enabled Mezzmo was transcoding each file to hls on the fly, this can take some time to start playing if the video is HD as a full transcode is performed. With transcoding disabled the files started playing quite quickly but it was not possible to seek within the file. The Roku only supports seeking on hls and not on ts files. Please try disabling transcoding in Device Settings on the Transcoding tab to see if the files play. If they do then you will need to determine if you require the ability to seek within the file and then this may require pre-transcoding.

    For the issue with the PQ and artifacts it may be because we are not specifying a crf value when transcoding, you can try editing the ffmpegAdditional.xml file in your Device profiles folder and adding -crf 22 to the h264+encoding+ultrafast values.

    The Roku supports seeking using thumbnails of the video so this is a nice advantage of using the Roku over the Sony Bluray player, if you don't see the thumbnails when seeking you may need to maintain the file in Mezzmo and check the box to update video preview thumbnails.

    I already have transcoding disabled (no check in the box) and it's in that configuration the .ts files do not play (described in message 14 in this thread; progress bar flashes for less than a second, and beep, followed by nothing but the same screen I was at). That the .ts files you tested play successfully but don't allow "seeking" (not sure what playback features that encompasses) is different behavior than I get.

    My Mezzmo server is short on power for stutter-free transcoding on the fly. It's CPU is an Athlon II X255. Pre-transcoding files (.ts to .hls) would be the only realistic path open to me for the Colossus-created files when NPVR records TV shows or sports event. I'll test your suggestions to improve the PQ and share the results with you.

    Peter, adding the -crf 22 parameter apparently caused the transcode to fail. I've attached the log Mezzmo generated.
