    Cannot stream live TV (same channel or same transponder/mux) to more than 1 client at the same time

    It is impossible for me to stream the same channel (or a different channel from the same sat transponder or terrestrial mux) to more than 1 endpoint client at the same time.

    The endpoint clients have been multiple device types: Windows PC, Raspberry Pi running OSMC, MacOS etc.

    All of these devices are capable to playing a stream.

    However, it is not possible to initiate a 2nd simultaneous stream --- I have tried this in many combinations/permutations.

    The only way I can make the 2nd device play a stream (and the "2nd" device has been a variety of devices in my testing) is to stop the existing stream.

    My understanding of the technology suggests that I should be able to stream to multiple clients from the same Tuner/Transponder (limited only by network bandwidth and hardware resource performance). Other posters have confirmed that this case under normal circumstances.

    Is there a bug or limitation in the Formuler F1 Openvix image that is preventing me from getting this working?

    Is there a setting I need to modify?

    Thanks in advance.

    Does it happen also with FTA channels?

    Hi - thanks for replying

    Yes it happens with both Terrestrial (Irish Saorview) and Astra-sourced FTA satellite.

    If 2 channels that will ultimately require 2 separate tuners - e.g. - 1 is terrestrial and 1 satellite -- or both are satellite but require the 2nd tuner (because it's a different transponder / polarity / etc) then 2 channels will stream simultaneously.

    The issue seems to arise when the Formuler F1 box is tasked with more than 1 request - and those 2 requests can be delivered by a single tuner (from a purely tuner technology perspective).


    It cannot deliver multiple streams from a single tuner.

    Openvix is also not even engaging a 2nd tuner (where available) to generate a 2nd stream. This would be, of course, not a desirable solution - as it would only scale to 1 stream per the number of available tuners of that type.

    Thanks again for replying!

    Does it seem like a bug?

    Streaming requires a different tuner from direct viewing.

    Ok thanks ....

    But I can stream from the tuners ..... I just can't stream to more than 1 device at a time from a tuner.

    Each of the endpoint machines are able to play the stream - if no other machine is already consuming the stream.

    I'm assuming this is not an intentional design behaviour.

    Streaming normally - generally speaking - supports a one-to-many relationship where a single server entity pushes a commonly-addressed stream over a network ecosystem and multiple device can then receive and consume the streamed media.

    The only constraints and limitations (in a freely available anonymously accessible stream) are the server hardware capacity for the task and the available bandwidth throughout the network infrastructure.

    I'm assuming that each client should not be addressing the tuner hardware directly and that the OpenVix OS distro is serving the stream in a black-box manner to the client through an appropriate service.

    So, it seems that a "1 stream client per tuner" limit is practically in effect - either by design or by accidental happenstance.

    Can someone please confirm that I should be able to stream a live TV stream to multiple endpoints at the same time?

    Thanks

    If it is the case that simultaneous streams (ultimately being server from the same tuner) is expected behaviour, then there is either a bug in the Formuler F1 Openvix image, or I have something broken in my configuration.

    I have tried and failed to get this working on multiple different flashes of multiple different builds and I have never seen it working as I think it should typically work.

    Thanks again everyone for reading and posting!

    Expected behaviour is one tuner per stream.

    But more than one endpoint should be able to consume this live stream - yes?

    A live stream is the same data - regardless of how many clients are consuming the stream.

    Is it designed behaviour that only 1 device can consume a live of stream of (for example) BBC 1 at a time?

    So 2 people, in the same house, in 2 separate bedrooms cannot watch the same live stream of the same channel at the same time?

    I'm sorry if I appear to be asking the same question, but I haven't really seen a direct answer to that specific question: is there a deliberately designed limitation (or technological hardware/software limitation) that prevents 2 end users consuming the same live TV channel stream at the same time?

    If there is a designed reason, could you please explain the logic of it.
    If there is a technological limitation, could you please explain that to me - as I can't think of one (but I am happy to be corrected and learn something new).

    You would have been better off with an FBC tuner capable box

    OpenWebif on 2 different laptops allows me to watch the same channel the tv is tuned to (or any other for that matter), using a vu ultimo4k on terrestrial freeview.

    Only one tuner is being used for the same channel/mux, but more than 1 if different mux's are chosen.

    Maybe there are different interpretations of the word "streaming"?
