HW does not read embedded subtitles. - MX Player

Hello guys,
Current files used: HEVC around 2000/2500kbps + aac 128/64kbps
I'm having some issues with the HW+ mode, constant micro stutters.
With HW only, video plays perfectly fine, but it does not read the subtitles embedded with the file (MKV).
I've tried with a Galaxy S7 Edge, XPeria z5 and a Android TV box based on Amlogic S905W.
On all of them the symptoms are the same (Micro stutters using HW+ and no subtitles using HW).
PS: If I start the movie using HW+ and then change it to HW, the subtitle is present.
Thanks.

HI,
are you playing from a network location?
HW decoder basically usee mediaplayer API provided by the Android. If it doesn't detect the subtitles it may happen. When you use HW+ or SW decoder, FFmpeg is used. So, it can detect almost all formats. That's why you are getting subtitles when switching to HW from HW+.
Regarding HW+ micro stuttering,
Does it happen when you copy the file to the device storage?
Can you collect a bug report immediately after noticing the issue & share with us? We will check it out.
If it's possible, kindly share a sample file with us. We will check it out.

Just a quick update:
I tested on the S7 Edge after a reboot and it's working fine.
Also tested on another S905W based box (TX3 mini), and the HW+ micro stutters continue :/
The box tested before is a X96 mini (both of them are based on Amlogic's S905W processor/board).

Hi,
We couldn't find anything abnormal on logs.
does HW decoder work fine on both of these TV boxes? The stuttering may happen when there is a rendering delay on the device side or when there is a delay in the decoding of the frame.

Yes, using only HW (not HW+) it plays smoothly.

Can collect the bug report & share here.
FYI, now if you disable the subtitle on one video it will be disabled on further playbacks. You have to manually select the subtitle again. Once you select the subtitle it will be enabled everytime till you disable it again.

here is the log......... first i played the video with alternate hw+ and the subtitle didn't show..next i played it with older hw+ and subtitle showed........ then took the report
I cannot remember what video it was, but it was an mkv, when playing a video the subtitles would show even though they were disabled, then if i enabled subtitles i would have two identical sets of subtitles, though one set was a few pixels apart from the other.

Subtitle rendering & Media Playback both are individual functions. It less likely to conflict.
Just downloaded the original video & tested myself. After test & trails I have found that "Improve SSA rendering" option in Settings > Subtitle > Text is somehow affects when using new HW+ decoder for video decoding. Report passed to the developer. Just disable it as a temporary solution till the developer fixes the issue.
Edit: Update from developer
@caspianprince
It's internally fixed & next update will fix the issue with SSA subtitle rendering issue when used with new HW+.

Corruption in small to medium parts of the video is a reason i dont use HW+ i would rather use HW with lower volume.

New HW+ is available only to the devices with android 5.0+. Old HW+ method may not be compatible with old devices especially when the android media framework is modified by the OEM or by Rom developer in case of custom rom.

It's not a bug. Android 5.0+ provides a official API to use system decoders in native programming language. When a particular encoding profile is not supported you may still have issues in new HW+ as well.

HW+ - Normal video speed and sound, but image has intermittent break-up from small to large areas.
HW - Frozen perfect image, if you select another point in the video, you get 1/2 second of playback and then a freeze, perfect image

It looks like a system decoder issue. If it's supported it suppose to be playable in HW decoder. When you have tried HW decoder, it hows thrown a unknown error. Does any other player works? I think that particular video will have issues with every player?
Can you try MX Player Pro 1.8.9 beta 2 & share the bug report again?

MX Player Pro Plays Choppy MKV after Latest Updates

Hello
I recently updated MX Player Pro to 1.8.10 and was also prompted to update the custom codec to 1.8.6 . Not the best decision i ever made as now MKV is virtually unplayable and choppy .
If i open the same files in XBMC on my MINIX Neo U1 everything plays smoothly including large MKV .
I hope this can be fixed . And as its my first post , i'd like to say hello to all of you and to thank you in advance .

Basically HW & HW+ will be very smooth if it's supported by your device. SW uses CPU instead of GPU. So, it will be laggy if the processor is not powerful enough.

I personally prefer HW+.
Enable HW+ from Decoder Settings. If you are on Lollipop (5.0) or newer android version, enable Alternative HW+ as well. Most of the time, HW+ works better than anyother decoder.

Thanks both for the tips .
The only problem I sometimes have on my Minix Neo U1 is that when a video plays , unless I choose sw decoder at the top of the video screen I will occasionally get the audio playing very echoed unless sw decoder is used .
The videos play smooth with HW + but audio isn't played right .
Bh ghe wqy , The Minix is a great player and can handle files 8gb plus and also 4k easily.
So not sure why the audio likes sw decoder !
Anything i can try ?
Thanks again .

If it's so, just enable SW audio in decoder settings. It will enable SW for all videos.

HW+ Issues on MX Player 1.9.7

anyone else get choppy hw+ playback on their oneplus 5? issue disappears completely when using sw or regular hw decoder
I'm finding the MX Player betas are really flakey right now.. The lastest one fixed seeking with the remote control (finally - was broken since the last stable) but somehow broke HW+ decoding on the Nvidia Shield TV, which has always worked flawlessly before.

It's every streamed video on the Nvidia Shield TV. I've got SMB shares mounted on the Shield and these "local" videos all works fine.
Where things are broken is with network streamed (I generally use Terrarium TV). HW+ and Software decoders both now refuse to work, only HW works after the last MX app updates and even HW crashes midstream at times complaining of not supporting the video codec (even though it's already been playing just fine).
Here's a bug report directly after starting play of a streamed file as HW, and just after I've tried to use HW+ and Software (to try and ensure it contains something useful).

No hardware decoding on H96 Max

Hi.
Recently bought H96 Max TV-Box and installed MX Player Pro on it.
But player can't play HEVC H265 videos in HW mode.
When trying to switch to HW mode it says it is not supported.
HW+ option is greyed out(not available) at all.
Currently using SW method but video playback is very bad with this method and it is impossible to watch with this method.
TV-Box based on RK3399 processor that claims full H265 hardware decoding support and I know it does because built in players can handle this file without problem with smooth playback.
How can I get smooth hardware decoding in player at this device?
hi, I'm going to receive this TV Box as well,
have you solved this problem? I'm a bit afraid of that...

Hi,
Actually, the issue is that system decoders in your device do not report that they can support HEVC 10bit profiles. So, MX Player does not try the hardware accelerated playbacks as several devices are known to crash when force decoding 10bit HEVC & H.264.
Based on some feedbacks from the users like you, we have decided to make this logic as optional. From 1.9.19, even if the device doesn't explicitly report it's capabilities, MX Player will list the HEVC 10bit & H264 10bit on HW+ Video Codecs list on Settings > Decoder. It can be enabled with a warning. Once you enable the HEVC 10bit or H.264 10bit, it will be tried in both HW & HW+.
We have already started rolling out the new version in stages. If you haven't received yet, you can manually grab the apk from our wesite & try yourself. Kindly leave a feedback after testing the same in your device.

Low video quality unsing HW+ decoder

hi,
I have an Minix U9-H box (android 6.0) and when I play full HD streaming files from my ip tv provider using HW+ decoder, the video quality is poor. It's working fine with HW or SW decoder (The codec used by mx player is ARM V7 NEON).
I checked also in perfect player and when using HW+, it seems the player downgrade the video resolution to SD format.
Any clue ?

It should be a bug in the system decoder. In HW+, MX Player passes the frames to the system decoders to directly decode. Probably, the resolution of the decoded frame might be low. We have encountered a similar issue in the past especially when the stream is interlaced. If it's the root cause, then it has to be fixed on the firmware. You will notice similar issues with all major video player apps which makes use of similar technology.

Any clue ?

HW and HW+ uses GPU for H.264 decoding. They performance much better from SW which uses CPU for decoding. HW can perform better than HW+ in most of the Cases, but there is a chance it does not work smoothly on many devices.
Same
Same problem. SW is better than HW and HW+. (Android tv 8.1 - Mibox 3s)

It may happen when the Hardware Accelerated Decoders implemented on the device itself is buggy. Can you please contact us with screenshots of the playback on HW/HW+ and SW along with a bug reported collected from MX right after playing the file? It will help us to confirm the same.
There is no error, just low quality. HW and HW+ is same. SW is good.
The problem only occurs when viewing iptv (multicast - udp), watching the file on the hard disk is ok

It is one of the known issues on Xiaomi's TV boxes with Oreo and Nougat firmware. Based on our past investigation, it has been found that the hardware accelerated decoder's output resolution of the video frames is much lower than the actual frame size. As both HW and HW+ relies on the decoders shipped with the device, you can notice the issues on both. Request you to contact the device manufacturer so that they can fix the same on their firmware.
If it is possible, kindly share a link with us on PM or at [email protected] so that we can also escalate the same from our end.
I also tried on my phone (Mi Mix 2s - Android 9, MIUI 10) and it gave same results.

Can you please try any non-xiaomi device and check again? Can you also check whether it happens if you copy the stream to a file using FFmpeg? Without a sample clip or a link, we may not be able to seek the assistance of the Xiaomi team.

I don't have a non-xiaomi device. These are sample files. I saved them with VLC

Let me guess a bit: The format of the service provider is 1080i, this issue relates to the deinterlacing algorithm. With HW decoder, resolution halved.
maybe recode your video?
