Since the new USB player supports MKV, is it possible to get more details about MKV support? Do we need to just change the stream format to "mkv"and encode with the same settings as MP4 in order to get it to work?

For anyone that hasn't seen it, the sticky thread in general forum may yield useful info:

I can't seem to figure out what StreamFormat will let us play MKVs in our own channels... but I'm not giving up! 😛
I've tried "mkv", "matroska", "mkva", "mkvb", "h264", "mp4", and even "hls" for the heck of it. No go for any of them so far. I suppose it's possible they've not enabled streaming support for it, yet...

OK, I installed the USB channel and when through a upgrade to the box.
Now the USB channel plays a mkv video I have, great !
Now, HOW do I stream it from my channel ?
Tried changing type, but no go !

Maybe there's a super-secret way that will only be available once we read the 2.9 SDK. Or maybe we have to wait until v3. I really would like another container besides MP4. MKV (without testing) looks like it could be streamable -- much like AVI. I don't care about the FLV container because it's just like MP4. What would be awesome is MPEG2-TS support (non-HLS) and MKV. I don't really care about codecs -- H264 and AAC are great. I'll be honest, I only care about more flexible containers. Let me build/stream the container easily. HLS is a start -- but it requires much more effort to get working correctly.

There are multiple matroska containers, and you must use the correct one for your stream url. Fortunately, they are easy to remember as they match the typical filename extension.

For ".mka" files, use StreamFormat = "mka"
For ".mkv" files, use StreamFormat = "mkv"
For ".mks" files, use StreamFormat = "mks"

Is streaming of these formats supported with the latest firmware? If so, I might be inclined to think that you are awesome.

To clarify...I mean...can I stream them from an HTTP server like normal media (MP3, MP4, etc.).

The streamFormat value for playing MKV video is "mkv", but you will also need to add a line to your manifest file: requires_mkv=1

I haven't test it yet -- but you guys have no idea how happy you've made me.
