Adaptive streams does not change resolution - MX Player

Well recently I used mx player to stream some DASH and HLS streams,but one thing I noticed is that it won't change resolution no matter what the network speed is,other players do change resolution when the speed drops,is this a bug?

We regret to inform you that adaptive streaming is not supported in HW+ and SW decoder at the moment. For HLS, we recommend you to use HW decoder whenever possible. It will fully support adaptive streaming. For Dash, unfortunately, android media framework doesn't support it natively. So, It can be played only with HW+ or SW.
However, we will highlight this with our relevant team and do our best to bring adaptive streaming support on HW+ and SW decoders.
Thank You.

[Q] 10 bit 1080p Video

Has anyone tried 10 bit video yet? How does the shield perform?
It works fine for me. I've played the Video in XBMC, MX Player and VLC. All of them are able to play my highest quality stuff (2GB MKV with a length of about 24 minutes) with SSA subtitles with no lag. However, in XBMC and MX Player there is noticeable corruption in the image and discoloration as well. It is worse the higher the bitrate with it being most unnoticeable with 10bit 720p video. There is a hint of it with 8bit, so much so I'm not sure if it is an optical illusion or not. For whatever reason I did not see this with VLC. I think it is because it was using software codec versus hardware codec. I'm not entirely sure because VLC would crash if I took it Auto for which Codec to use. Also the H/W+ codec in MX Player would crash no matter what video I tried to play (resolution or 8/10bit). Also XBMC would crash if I limited the codec to only Stagefright. The other Hardware Codec and Software Rendering worked just fine.
Dear trowgundam,
did you try the version v1.7.31 of MX Player Pro? It now supports natively the K1 but it isn't so stable...

Just to clarify that I'm using v1.7.31 of MX Player Pro and the colour corruption\pixelation is still present with HW+ or HW decoder used. SW decoder works fine for most purposes. I see the same problem in XBMC (latest nightly) with Hardware acceleration used.
I did find the performance suffers a little bit with the SW decoder (got a lot of dropped frames on a very high bitrate version of Psycho-Pass I was watching but everything else seemed fine, nowhere near as bad as my old Nexus 10 however which is a massive plus). The tablet gets quite hot and battery life really suffers as I'm guessing only the CPU is being utilized?
It's a damn shame because the HW decoder works fine with 10-bit video apart from this problem but it can get so bad in certain scenes that it's not really usable.

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.

Blurry video with hw decoder

Hello everybody, I have this problem:
When I use hw decoder I get perfect sound but video is blurry.
When I change it to hw+ I have perfect video but no ddp or dts sound. Any solution?

Is it a local video or network stream?
HW decoder basically uses android mediaplayer API implemented on your device. If it is a network stream ( specifically HLS or DASH) it may happen due to adaptive playback. It will automatically select the best stream based on the current bandwidth. In HW+ or SW decoder, it will always play the first stream despite the bandwidth availability.
The problem occurs with local videos, mkv with ddp or dts sound. It is quite strange: Videos look like being projected on a screen with retention problem with hw. With hw+ videos are fine, but no sound

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.

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

https://www.mediafire.com/file/wjhcmec367uhwxr/test1.ts/file
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?

Can screen size change the way a video file is played or handled?

Today my new TV arrived, I bought the xh90 to get myself ready for the upcoming gaming consoles, although the quality of the TV looks great, when I tried playing some files off my hard drive through the nvidia shield TV pro, 1 particular season always chops/screen freezes after a while, (this has only happend with this one series, all of the seasons are choppy) Everything else seems to play fine for now, also when I play the file through VLC everything seems to run smoothly, while with MX media player it does not.
The real kicker is on my previous TV the file is not choppy at all, neither with MX media player or VLC, the only difference seems to be my new TV is slightly bigger, 55 inch compared to my 41 inch previously. Does it perhaps have to do with the way MX media player encodes the file depending on what screen size you have?

We would like to let you know that MX Player's HW/HW+ decoders make use of the hardware acceleration provided by your device. So, the performance will heavily rely on the multimedia capabilities of your device.
Regarding your issues, could you please specify the decoder used? MX Player's HW decoder directly use the android mediaplayer framework. In case if you noticed glitches with HW decoder, it might be caused by a firmware bug. Please click/tap on the HW button on the playback screen and try HW+ decoder. It may fix the issue.

Switching to HW+ fixed the problem for me, around 90% of my files are able to play through HW+ now, the rest I have to switch back and forth between mostly SW and sometimes HW.
I'm glad there is an option as well to "always play files through HW+ decoder", otherwise I would have to re-select the encoder every time I would want to play a file from HW to HW+.
You're the only person who replied and I'm grateful since that was enough to help me resolve the issue.
