If there is some missing information to my question, please let me know. This should be an easy answer for any programmer.
Not sure why tickets have to be open comming up on a month, before an answer is given, if at all. Is there a more active Roku forum out there? Thx
No, there is no better forum on Roku. There are however paid "evangelists" on staff at RokuCo that whose job is to help people like you but are rather reclusive for some reason. Everybody else whose name does not start with "Roku" - we are just volunteers in answering questions, can't be compelled.
Sorry for the situation. I think the reason is that your first question shows big confusion about Roku development (how do i show picture instead of video - that's apples and oranges), then you did not know if your code is SDK1 or SDK2... and people are "i am not touching this, will take too much effort explaining". Re mp4, should be as easy as changing <streamFormat> from hls to mp4 and then in <streamUrl> changing from the m3u8 URL to a mp4 URL.
