Hi,
i have single .ts file, which is large. Roku does not have feature to play such big file. it always tries to download full file before playing. and also RoKu does not support EXTINF HLS4 discontinuity option.
So, i need to write in m3u8 with minimum 3 .ts files.

I was trying to convert but download is failing with all options i tried for ffmpeg.

Could you please help how can i play this in roku or how can i convert this to m3u8.

Error below.

Based on the ffmpeg information, this is not a local file, so I can guess that the Roku Media Player (which is what I'm assuming you are using to play it) wants to download the file before beginning playback. You might have better luck using a DLNA server to act as your supplier of the media, and let it stream the Internet file. That's the only successful method I've used for non-local files that are coming from the Internet. Serviio is one such server that can stream from the Internet and feed your player.

I've had pretty good success with a good number of web based files using Plex's "Watch later" feature. However for that to work you have to have a Plex server setup and running on your network and you have to enable the "Plex it" feature in your browser. Once you have done that all you must do in navigate to the video in your browser and click the "Plex it" button and if it is a compatible video Plex will add it to your "Watch later" queue and then you can navigate to it in your Plex channel and play it just like a local video.

Roku never downloads a whole file before playing it. It has no place to put that much data. And it does support the #EXT-X-DISCONTINUITY m3u8 tag, if that's what you mean by "discontinuity option".

@RokuMarkn Team,
I have written my own application video player using brightscript example simlevideoplayer.

You can't. It's not an HLS stream, just a single segment file. You need the manifest file (.m3u8) for the live stream. You can't convert a .ts file into a .m3u8 file.

The .ts file is a mpegts live streaming file. any way to convert to m3u8 using ffmpeg command.

There are a couple different ways to play it.
Easiest for me was to create a test.m3u file on a usb stick and put that link in there and let rmp play it.
Easiest for you is to probably just make sure you set the streamformat to "ts" and play it.

Hi RokuDale,
when i tried to run by changing streamformat, it is playing only few seconds 20 or 30 seconds and then exiting automatically with below error.
I am using samplevideoplayer example.
