mbnwa Posted March 2, 2018 Author Share Posted March 2, 2018 (edited) @@Zodler As far as converting MKV to MP4 if you have a Mac you can use Subler as it sets the correct flags for the Apple TV - Keep in mind converting to MP4 with Subler you will lose all HD / DTS tracks as they will be converted to AC3 or AAC A few threads are going on about HDR -> SDR conversion but they are just discussions at this point and take quite the CPU power due to being single threaded to perform the tone mapping. Keep in mind with Apple being a walled garden what they support is limited and I think based on what @@ebr stated that’s why the Apple TV transcodes vs trying to play something the Apple TV would fail to play Sent from my iPhone using Tapatalk Edited March 2, 2018 by mbnwa Link to comment Share on other sites More sharing options...
Zodler Posted March 2, 2018 Share Posted March 2, 2018 I do not want to convert HDR to SDR. I'm on windows. I need a windows MKV to MP4 solution. Infuse or MrMC can play them, so Emby app should too. Link to comment Share on other sites More sharing options...
mbnwa Posted March 2, 2018 Author Share Posted March 2, 2018 @@Zodler Your still limited to what the Apple TV can play natively that’s where the issue comes in not all H265 / HEVC MKVs are created equal. I don’t know a way to properly object the required flag into the MKV container so the Apple TV would see it. However maybe @@ebr has some additional details I am missing.

chriskeens Posted March 3, 2018 Share Posted March 3, 2018 (edited) maybe the file that is not working correctly has the codec tag - hev1 instead of hvc1 try using a hex editor (use the find/replace function) to search for hev1 and replace with hvc1 - then save it ... this has worked with most issues of similar type that I have had Edited March 3, 2018 by chriskeens Link to comment Share on other sites More sharing options...

mbnwa Posted March 6, 2018 Author Share Posted March 6, 2018 Correct this is with the native Emby app for Android TV, no it’s not doing HDR to SDR conversion but it passes the HDR data along with the stream and my OLED is decoding it as long as Emby is not transcoding.

Luke Posted March 6, 2018 Share Posted March 6, 2018 With the beta server this should no longer be lost on the direct stream, assuming you follow the instructions here: https://emby.media/community/index.php?/topic/56614-3305-video-range-info/ Thanks. 1 Link to comment Share on other sites More sharing options...

Sent from my iPhone using Tapatalk Thanks. I installed and am using mrmc on apple tv as Emby Client. It has 3 major things that the official Emby app can't do. 1- It switches the TV to HDR on HDR playback 2- It has much better and more beautiful subtitle renderings 3- It can do HDR to SDR conversion. If I set the Apple TV to not match color range, it can play back HDR content in SDR. Link to comment Share on other sites More sharing options...

corey Posted March 7, 2018 Share Posted March 7, 2018 Apple is very particular about the supported codec and I think the tag needs to be hvc1 and not hevc. @@ebr can keep me honest though. Link to comment Share on other sites More sharing options...
ebr Posted March 7, 2018 Share Posted March 7, 2018 The codec is okay but there needs to be a codec tag of "hvc1" and that appears to be missing. Also, be sure the subs aren't selected as those will obviously cause a transcode as well. Link to comment Share on other sites More sharing options...
