Ffmpeg believes it has finished and so does Emby. It has deleted the transcoded TS file already. But the Roku wants it still as it believes it still has more to play (blame the header?). This is very, very, very, (insert 100 more verys) much a problem with hardware acceleration or some ghosts.

@elhuevon You might try with MKV and have different results. Rather than re-encode the streams. Just re-container-ize. Maybe inside MKV they play nicer.

@speechles

I assume this is more than renaming the extension from mp4 to mkv, correct? What do I need to recontainerize to mkv?

Just process it with mkvtoolnix.

It won't be able to demux the MP4.

@elhuevon You can do this with ffmpeg. If ffmpeg is in the path the below will work. Just point "input.mp4" to the full path of the file you want to convert.

ffmpeg -i input.mp4 -vcodec copy -acodec copy -c:s copy output.mkv

What makes you think that?  MKVToolNix happily reads and demuxes mp4, avi, ts, and I don't know what else; it only writes mkv, though.

I did both suggestions using ffmpeg  in a cmd window and running the file in MKVtooknx.  They both spit out fine mkv files but neither would play on the Roku.  The Ref Frame is still 16.  Which I would expect since neither option is changing anything that I can tell.  I didn't see any settings in MKVtoolnx to change Frame setting but I'm not sure where to look.  The problem seems to be more than just the container.

I cannot find anything official but I have found discussions of people having trouble with videos on the Roku when the ref frames are over 9 although some reference up to 12 working okay.  I cannot find any examples of videos with 16.

I looked through various media types on my server, everything is lower, a lot lower than 16.

Is there an easy way to change ref frames without reencoding?

Reencoding is the only way.

I'm willing to do that. Which program would be recommended, Handbrake?

Yes, or the server's built in conversion feature.

I copied three files into a test folder that Emby can see.  I started the conversion process.  They either immediately fail or they get to 60% and fail. Then I just put one file in the folder with a  custom profile to convert to mkv.  That failed quickly as well.  The log file has a lot of errors. See attached.

One thing you could try is turning off hardware transcoding in server transcoding settings and see if that helps with that.

Was just testing this on file provided and I don't get this QSV decoding error but am on Windows stable and beta.  May be driver related.

Is this a headless server? 

Encoder QuickSync RDPDD Chained DD - H.264 (AVC)
Decoder QuickSync RDPDD Chained DD - H.264 (AVC)

Adapter #0: 'RDPDD Chained DD' Id:0 (Driver: 655378.659785, Vendor: 0, SDK Version: 1.11)

Hardware Video Acceleration Fails with Remote Desktop (RDP) on Windows : Emby

@softworkzwould this be correct?

Your hardware (CPU) does not support DX11, only DX9, which means that you need to have a monitor connected and Emby Server must not run inside an RDP session in order for HW acceleration to work.

The server runs on Win7 but I admin it through rdp as needed (headless) never been an issue.

So conversion should work if I'm on the server (not in an rdp session) or follow the link to make a GP change, correct?

Disabled HW acceleration (took a second to find).  Did  two files one a TV profile and the other a custom profile again.  They did not fail this time.  They converted and copied over.  Most importantly they played on the Roku.  Still need to double check the Rokus in the house and maybe try a few other files but this is looking very promising.

What does HW acceleration do?  Should it be re-enabled  after all the conversions are done?

It can use the chip on  your video card or integrated video to speed up graphics operations.

Probably not unless you plan to connect a monitor to the server.

What options do have available in Transcoding "Enable hardware acceleration when available:" option Advanced?
