Played the jazz video on Both players, looked same and it looked to have more brightness then the other non-HDR videos, but not enough like the other 1080p hdr video i played before. Colors looked great too. Played in crop mode on stock and 100% on mx.

Im unable to upload all the screenshots due to my slow net.

It might be due to values specified in the meta.
If it doesn't work with any other files, let me know.

Question HDR Video Playback Discussion Thread

In general the stock mediaplayers are based on mediaplayer api. So, technically MX Player's HW Decoder (not HW+) should be able to replicate the behaviour of stock one as it's based on mediaplayer api. If it doesn't work with MX's HW & works on stockplayer, we really need to check whether the issue is on our side or nit. samsung may not be using mediaplayer api or dynamically adjust the brightness values externally based on the metadata.

We do not have a S8 device to test. It will be better if you can provide some information like what are the videos (may be some links) working & what doesn't. It might be helpful to understand the issue better.

I tried the Jazz video posted here and my S8 play the video but it doesnt play it with HDR no matter if i play it with MX player or samsung player. So far the only video that has played with HDR on my S8 but only using the samsung player is the video found on below link. MX player, plays the video but without HDR.

In this video you really can see the difference in colors and details. The only way I see you can see that you can be sure that you are playing with HDR active is because the samsung player show the legend HDR, please see the screenshot, from here and the differences in colors and details i can assure that MX player is not playing it with HDR active because colors are all wash when you compare both.

So if you want to try if a video plays with HDR or not just use the samsung player and if you see the "HDR" in the screen like in my screenshot that means that the video is playing correctly with HDR otherwise is not even if you see nice colors and the video looks good. It will look much better with the HDR active.

Is there anyway we could activate HDR on MX player or will this be a feature to be added on future releases?

I am still unsure about Samsung's implementation. If it's system level, then MX's HW player will mostly replicate Stock Player.

Have you enabled "Video Enhancer" on Device's settings..?

Anyhow I will forward your comments to our developers.

I havent touch that option. But I am not that it is not related to what we are talking here as you clearly can see when HDR is active or not, at least on samsung player. It will be really good if MX player developers could implement this or fix it if is a bug, as you mentioned earlier that samsung player should be using the normal implementation, which MX player should be using as well.

Can you try the following?
It's from a user feedback.

Enable "Auto Backlight". After that Enable "Video Enhancer" (MX Player will be automatically listed there)
Then try the same file in MX Player. Hope both HW & HW+ decoders will almost match with Samsung Player like more vivid colors & brightness values. Samsung might be using this functions automatically for their video player.

Meanwhile our developers are exploring the possibilities of adding native HDR support on supported devices. As we are still not clear about the OEM's implementation we can't assure anything at the moment.

I tried what you mentioned and still plaing the video using samsung video player is showing much better color and image than MX player, playing the same vide camp using HDR by samung video player and not by MX player, it is night and day the difference so this options are definitely not related to HDR.

The Samsung video play has a video enhancer setting (I have used it for years on my Samsung Tablet oled display), it seems to make whites whiter and the colours brighter, But in dark parts of a video you can loose detail and the image looks darker than it should so i turn it off for those parts of the video on a tablet there is a button at the top right of the screen to enable and disable it, though on a phone it might be in the menu.

Just to throw in 2 cents here, I have tested HDR10 on both S8+ SD835 version and the LG G6 SD821. Only the LG G6 shows the correct HDR colors. The S8+ shows colors to be much lighter and paler. If you doubt this then try looking for a UHD version of the Smu*fs 2 with HDR10. On the S8+ all colors appear much paler in both HW and HW+ decoders using MXPlayer.
On the LG G6 they appear in the correct bright colors using both HW and HW+ in MXPlayer.
Even using the Samsung video player on S8+ gives the same dull colors so it must be something wrong with the device codecs, perhaps not having HDR support.

Just tried to screen capture on both playing the jazz demo video posted a few pages back but just blank so took a picture of both screens at once. Excuse the poor picture but I think you can guess which is the S8+ and which is the LG G6?

HDR10 compared

Tried playing the jazz demo HDR10 on my ZTE Axon 7 as a control (no HDR display) and same results as S8+, pale, dull colors. For some reason S8+ is not rendering HDR10 correctly. Perhaps this is why Netflix doesn't support HDR on the S8+ yet?

---------- Post added at 09:59 PM ---------- Previous post was at 09:49 PM ----------

Bug report on ver 1.9, if I enable decoder, HW+ audio codec for a codec that doesn't show 'hardware acceleration' when playing a video with that audio codec it will playback scrambled sound. Tested on S8+ and LG G6 using that Jazz demo HDR10 video with aac sound. Was wondering why it sounded so strange

Jazz Demo displays HDR in both native and MX Player on S8, no sure what and how you're testing.

It plays but I am not seeing any of the HDR at all, it shows exactly the same as my Axon 7. From my posted pic the red balls are all showing duller shades than they should be, the saxophones, symbols etc are all dull yellow instead of the bright brass sheen they show up to be on my LG G6.
I went back and watched some of the Samsung TV HDR10 videos and saw what was missing before on my LG G6. Pretty much all the lighting from reflections on water to the sun casting a red hue on the landscape and orange shade across the sky. All this is missing when viewed in the S8+ and it appears no different than any other non HDR display.

what Screen Mode are you using? only Adaptive supports HDR (Video Enhancer should be ON).
