    The upcoming Mezzmo v5.0 has URL streaming and you can manually add your own URLs into your Mezzmo library. However, Mezzmo still interrogates the URL stream using FFmpeg to determine it's codecs, resolution, bitrate, attributes, etc. So you will still have the same problem as you have now due to the HDHomeRun's firmware response.

    You can adjust FFmpeg's HTTP headers. See this documentaion - https://www.ffmpeg.org/ffmpeg-protocols.html#http. However, Mezzmo's use of FFmpeg to interrogate audio/video files is internal within Mezzmo's application code and (at the moment) cannot be modified externally by users.

    Paul,

    Silicondust support responded with the following:

    DLNA requires for certification that the prime reject the request if the range tag is set as the content is not seekable (live) so to be a DLNA certified device the prime is behaving as it should

    you may wish to see nicks original comment about this to the kodi crew http://trac.kodi.tv/ticket/14204
    You may view the thread I created with them at https://www.silicondust.com/forum/vi...p?f=47&t=21402. They seem to be of the opinion that it is Mezzmo that is not following the DLNA spec.

    I guess I'm waiting for Mezzmo v5! Thanks again for your assistance.

    Thanks for the follow-up. We understand SiliconDust's comments as to why they reject the FFmpeg request for their DLNA certification. We think we can get around this problem. Email us at support [at] conceiva [dot] com and we'll provide a patch for you to try.

    I'll give a patch a try, email sent. Thanks!

    Edit Below:
    Simply dropping the ?dlna from the HDHomeRun url will allow the HDHomeRun to respond as a upnp device which is not bound to the strict dlna spec. Without the dlna variable the http request will be accepted & the stream delivered even with the ffmpeg http range header.

    Using 41337, videos are now transcoding & the transcoded stream delivered to the playback device. Playback quality varies but I suspect that's mostly due to the cpu capabilities of the hardware running the Mezzmo server. There are a couple issues I noticed that I don't think are due to my hardware & config to consider for future releases.

    - The Get FFmpeg Information option returns a HTTP status of 406 & fails for the HDHomeRun stream.
    - The "Get Properties From File" action must be used before transcoding will be triggered. If the file properties are not retrieved prior to playback the stream is delivered to the playback device in its original format. Transcoding does not occur.
    - If playback is started, then stopped, then started again, playback will resume at the start of the transcoded file created by the initial playback. Playback will continue slightly past the point where the initial playback was stopped, perhaps to when transcoding was stopped. A new transcoding session is not displayed when the second playback is started. The expected operation would be that playback is always started at the current time in the live TV stream. Deleting the transcode files allows playback to start at the current time as expected.

    It's getting late here. I'll likely take some new logs tomorrow and send them your way.
