Lags when playing AC3 audio - MX Player

Dear MX Player community,
This video has track #2 in AC3 format (44.1kHz, mono). When I switch to this audio track it starts lagging (voice trebles, some sounds are dropped). I have tried enabling/disabling S/W decoder (Menu→Audio→Audio track→Use SW audio decoder), but it does not help. Perhaps it is related to the fact that both audio tracks are muxed with 1/2 stretch ratio into MKV container. Nevertheless AAC track #1 is played correctly. Both tracks are known to play correctly on Media Player Classic v1.7.13.112 (LAV Splitter v0.70.2.80) on Windows 7.
Is given AC3 track playing smoothly for anybody?
I use MX Player Pro v1.9.16 with ARMv7 NEON custom codec on Samsung Galaxy S5.
The issue might be related to this thread, but I am not sure.

Nexus Player MPEG2 Hardware Decoding on Stock Rom

So, MX Player appears to have hardware decoding, but you have to side load the Intel codecs.
I am right now watching live sports through my HRHomerun Prime using this method.
1) Install MX Player from the market MX Player Free On Google Play
2) Side Load the Intel Hardware Codec from MX Player Side Load
3) Install the AC3 audio Codec from
XDA MX Player AC3 Audio Codec
To Watch HDHomerun Prime channels with the method play the network stream

SHIELD - MX player - AC3 cannot play even after internet recommended fix

When MX player lost its support to play AC3 audio I have found on the internet instructions how to fix it. I downloaded the AIO 1.7.32 codec package zip and set the MX player to use them. Despite this fix the problem still persists. (I think tegra 4 is not supported with this codec package)
Using this codec package Shield is able to play AC3 audio only for very short period of time.
Is there any other way how to make MX player play the AC3 audio?
use vlc less problems
My MX Player works so far properly after I changed the SW codec to HW+ one (I also use the AC3 external codec package) . There are also setting for SW/HW audio codec, just play with it.

[Feature Request]Surround sound output support

I am using MX Player on my Shield TV. One thing that totally broke the experience for me is that there is absolute no support for surround sound what so ever.
The only way to output any surround sound in MX Player is to use HW decoder. When it works, it is really great because it is the system handling all the surround sound. However, what I want to watch is encoded in hi10p so HW decoder gives me broken image.
I have tried everything but there is simply not an option to decode video through SW while decode audio through HW (Archos has it).
To make things worse, MX Player is not even able to output multichannel PCM properly while all of the other three players on Android TV has absolutely no problem with it.

Audio and Video out of sync

I have a number of videos with the following properties. Their video frame rate is 30 at 720p with codec of H.264 part 10, using Lavf57.27.100 to encode. The audio is AAC at 48kHz..
I played these videos on different number of android devices using MX Player with HW decoding. The video is delayed by a second or two. But with HW+. things seem ok.
I played these same videos on the same android devices using BS Player. The video and the audio are perfectly in sync.
How come? Please help.
BS uses a implementation similar to HW+ as default. So, you will get the result like HW+.
In HW decoder, MX Player uses the mediaplayer implementation from android itself. MX Player's control on it is very limited.
If HW+ works fine, you may just use it. From 1.9.0 HW+ will be enabled by default for all users with android 5.0+. But, HW will be the default one as usual.

Skip forward/backward function acts weird on my device.

I have a 2015 model of sony bravia android tv, and it has a MT5890 CPU and a mali T-624 GPU. I installed the latest version of mx player and armv7 neon codec.
I am able to play x265 coded videos with built-in video player without any problem, it's very smooth, and I can skip forward or backward or just jump to whenever I wish to.
However when using mx player, it's also very smooth, but I can only play from the beginning, if I try to skip forward or backward, or jump to a certain time point, it starts to act very weird. Sometimes video speeds up 2x or 3x, sometimes it slows down, like it's catching up or slowing down to wait audio to be synchronized. And it can take from couple of minutes to half an hour to go back to normal.
This only applies to x265 coded videos, I have other video that are coded with x264 or HEVC, and they work just fine in both built-in player and mx player.
I have tried other video players like spmc, kodi or VLC, they all stutter, VLC is probably the best among these but it is still dropping frames left and right. But most of them don't have problem with skipping or jumping.
Can someone please explain the reason? Could it be fixed?
Much appreciated!

Basically, x265 is an encoder for HEVC. So, both are same.
Maybe some particular HEVC profile has issues. Can you try HW+ decoder?

In fact I am using HW+ decoder, and it's the only way I can play those videos smoothly. Switching to HW or SW would make the video either completely unplayable or stutter very heavily.
To sum it up, I CAN play any videos with built-in player smoothly and drag or jump or skip however I want to.
I CAN play x265 coded files smoothly with mx player in HW+ mode, but I CANNOT jump or skip. I CAN play any other videos with mx player without any problem.
I CAN play x265 coded files with some level of stutter with other players like spmc and VLC, but I CAN drag or jump however I want to.
The videos that I am having problem with have these kind of parameters:
Format : HEVC
Format Info : High Efficiency Video Coding
Format profile : Main [email protected]@High
Codec ID : V_MPEGH/ISO/HEVC
Writing library : x265 2.5+4-b4a5bcfe29c7:[Windows][GCC 4.9.3][64 bit] 10bit
If the writing library is x264 or ATEME Titan KFE or ATEME Titan file, or if the codec ID is hev1, or if the format profile is Main [email protected]@Main, I don't have a problem.
This is so weird....
To the TC - Did you ever get this sorted?
I am having the same issue on my Sony Bravia. Whilst the actual player is exactly what I wanted, I get exactly the same issue when fast forwarding or rewinding.
I have played around with the different codec settings but it doesn't seem to make any differences.
Did you end up finding a solution?
Cheers

Glad to see that I am not alone. But unfortunately I did not find any solution and had given up on this.
After all, it is only a tiny fraction of all the videos have this kind of behavior.
Thank you for the confirmation
