Please try to answer these questions so we can help you get this going.
What is the source of the stream? Is it live or vod? If live, what type of encoder are you using?
By "translation" do you mean translating from one language to another? Or something else? Not sure here, sorry.
What module are you referring to? Is it a custom module?
What are the video and audio codecs of the stream? For iOS you need to use h.264 video, with a profile of "baseline" (baseline for most devices, while newer can handle a profile of "main") and AAC or mp3 audio. For mp3 the settings should be 64 or 128kbs, 44100hz stereo.
What guide are you following?
Thank you for your patience and we look forward to hearing from you shortly.
