[Bug] Android video driver crash under specific circumstances

Device Manufacturer & Model: LG Nexus 5
Android Version: 5.0.2
Rom Info: CM12 02/28 Nightly, tested also on CM12 02/15 Nightly
Detailed Problem Description:
Hi. I have encountered a very specific issue with MX Player. When I am playing full HD portrait video and next video is full HD landscape, the Android video driver seems to completely crash in the event when videos switch. E.g. when portrait one ends and landscape one starts playing. Sometimes the device freezes with corrupted graphics, sometimes it recovers, but graphics are shifted and reboot is needed to resume normal operation.
I have reset the settings to default when reproducing the issue and only setting I am using is Display / Settings / Screen / Orientation : Auto rotation. I am holding the phone in portrait, so basically the first video should be full screen on my phone and the second should be scaled down a lot to fit in portrait. It happens with both HW and HW+ codecs.
I have recorded two short videos which can be used to reproduce the problem. I have also recorded the behavior on the phone using another camera (this time the phone "kind of recovered").
Steps to reproduce the problem:
1. Install MX player.
2. Set Display / Settings / Screen / Orientation : Auto rotation
3. Play attached videos when holding the phone in portrait, the crash should appear when the first ends and the second starts.
See recorded video for details.
Logs from MX Player
Video 1 - portrait
Video 2 - landscape
Issue recorded using another camera to show what happens on the phone
It works in default video player and does not cause anything similar. I did not have a chance to try it on stock ROM yet. However, I have a lot of videos with different sizes and switching between them does not cause the issue. Just full HD videos.
Let me know if any more details are needed.

It happens on stock 5.1 too. Very annoying if you have mix of portrait and landscape videos recorded.

It looks like ROM issue if HW has same issue.
FYI, HW is default media player actually which is provided by the OS.

I did some more testing. It happens on all factory images I had for Nexus 5, 4.4.4, 5.0.1, 5.1. All of them exhibit the same problem. I tried also the SW decoder, but that did not tell me anything, as SW does not follow the tag for portrait orientation, so the portrait video showed up as landscape anyway.
Now the interesting part is that default player does not crash like that, when switching between the videos. But it takes longer to switch. It seems that it deletes the whole drawing surface and starts it again. Contrary, when switching videos in MX Player you can always see last frame of previous video stretch to the following video size before it starts playing.

[Bug] Android 5.1 - Unable to fast forward

Hi,
I am using
Nexus 7 (2013)
Mx player version : 1.7.38 ( ARMV7 NEON )
Custom codec : 1.7.32
A few days ago, my device was upgraded to Android 5.1. Now, MX Player is unable to fast forward or resume to the middle of a MP4 or Xvid file. I can fast forward a couple of minutes at a time, but if I fast forward, using the slider, for a long period, like half an hour, the screen is blank but there is sound. If I resume a file to a point in the middle of the file, the same thing happens, i.e. sound and blank screen. MX player and files are the same. Previously, I was on Android 5.02 and everything was fine.
Would appreciate if you can fix this.
If need be, I can send the logs from my device.

Hello
i have the same device with the same android and the same version of the player
And the same problem lol.
it seems the hw+ is broken on 5.1 so im using the hw and its working fine
i dont think you should use the hw+ until its fixed because its making the device lags alot when the problem occurs
hope it gets fixed soon

Thanks for the tip. H/W decoder solves the problem.

[BUG] Random crashes, freezing and audio stopping

Hello, since one of the latest updates I have been having a lot of issues with mx player acting up.
The problem started when I was listening to a video without the screen on and after around 30 seconds the audio would cut out but the video would continue to run. Either that would happen or it would freeze my device.
I have been unable to get a log of that issue but I just had a video freeze on me and the player crash so I will post it below. I have uninstalled and signed up to the nightly build but still getting the same issues.
Phone - samsung galaxy s7
Rom - stock unrooted
Version - 6.0.1
MX version - nightly Version 1.8.4.nightly.20160125 (ARMv7 NEON)
Log link = h**ps://drive.google.com/file/d/0By4WsG59vc5lNG9lV0psaUVTQnM/view?usp=drivesdk

Just encountered another freeze when the screen was off and managed to get a log.

@Penthus
The issue seems to be from system.
AudioPolicy Server & AudioFlinger dies while playing.
Does it happens with a particular file or everywhere?
Does it happen when the player is on foreground?
Does it happens when you use HW decoder (Seems that you are using HW+)?

It happens to a whole range of videos I view using the player and have not been able to reproduce it as it seems to happen at random intervals and not in the same spot. It can happen 5 times in an hour or a couple of times a day.
It happens when running in the foreground but less frequently. I have disabled power saving on my device to see if that was affecting it but does not appear to have made a difference.
I have tried SW, HW and HW+ to see if any were better than the others and they seem to crash with the same frequency.

Does any other apps having this issue..?
It seems to be a bug from the system.

It happens very rarely with my media player when the audio will stutter for a few seconds and the phone becomes unresponsive. It definitely happens a lot more frequently with mx player and it has only started the last couple of weeks.
Is there anything I can do on my end to see what might be causing the issue?

Just tried changing to HW again and got a freeze. The app recovered from the freeze and the video resumed but the audio didn't. I had to play some audio on my phone and then the video audio started again.

Thanks for your help so far.

@Penthus
Hi, would you try after turning off `Fade on start` and `Fade on seek` from Settings > Audio?
If audio crash continues, turn off Settings > Audio > `System volume panel` too.

Since turning off fade on start and fade on seek I have yet to have a crash or slowdown. I have been switching between sw, hw & hw+. So far so good, I will post back if I experience anything.
Thanks for all your help.

Wasn't sure whether to make a new thread or post in this one again. Seeing as the issue is similar I thought I should add to this one. Since having my last issue fixed things have been going perfectly until a few days ago when my videos started crashing with HW+ decoder. It was happening fairly frequently so I decided to to try out the other decoders and they all had issues.
HW+ as I said would hard crash out to the main menu with the crash report. HW would freeze and then start the video from the start. SW would have the video continue but the audio would freeze and then the video would roll back to sync up with the audio. It also seems to happen more frequently when I have headphones attached to the phone but that might just be statistical bias as I use headphones 99% of the time with my phone.
I have been using SW as it allows me to still watch videos although it can be a bit annoying as this can happen every couple of minutes or as frequently as every 5-10 seconds.
I have got log reports from each of the different decoders.

From Logs:
AudioSystem: AudioFlinger server died!
IMediaDeathNotifier: media server died
AudioSystem: AudioPolicyService server died!
The issue happens with HW as well.
HW decoder uses the mediaplayer API provided by android. The is used in the stock video player as well.
From the logs the The AudioFlinger & AudioPolicyService Server both has died for an unknown reason. So, mediaserver is also died. [all are system services.]
In some devices when the volume is changed very aggressively it may lead to the issue. This was the issue with OP. But, in your case you have already disabled audio fading. So, the reason is unknown.
Could give some more details....?
Does this happen with all videos or only in certain videos or certain formats..?
Could you try Stock Player for the same file in which HW decode crashes..? Let me know whether it has the same issue or not.
Can you provide a sample file in which it crashes..? We need to check it with our other samsung & nexus test devices.

Background play no longer works

Hi.
I just updated to the newest version. I love mxplayer pro. And one of my favorite things about it is the background play feature. Well it no longer works even when having it on. I am trying to play one of my videos from my Plex server and when I go to turn off the screen it no longer continues to play. Please help. Pixel XL running Android 8.0 Oreo

I am in the same situation (Pixel XL, MX Player Pro, just updated to Oreo) and background play stopped working. However, this does not consistently happen unless I am connected to a Bluetooth speaker.
I use MX Player for audio only often. This is the easiest way to reproduce the problem:
1. Connect to Bluetooth (in this case I have an Amazon Tap and I tell Alexa to connect to my phone).
2. After connecting start an MP3.
2. Press the power button to turn off the screen.
3. Wait a few seconds and the audio will stop playing.
4. Swipe to look at the notification for MX Player and note that the time in the MP3 is incrementing but no sound.
MX Player is *not* crashing. You can reopen the screen and press pause (wait) and then press play on the lock screen notification and MX Player will begin to play audio even when the screen goes back to sleep.
Note that this is not always consistent. It happens almost all the time, but I have done the above procedure and on some occasions audio will continue to play. Again, I think it happens much more often when connected to a Bluetooth speaker.
If you let me know how to collect a bug report or some sort of dev log when MX Player I will. But again, MX Player is not crashing when this happens.

I have the same issue since the last update on my nexus 5x running Android 8.
Update: it doesn't seem to happen when playing either local content, or a stream over samba. Only remote streams (I use megabox HD)

Ok, I was able to reproduce this. Apparently this isn't as cut-and-dried as any Bluetooth speaker causes it. I connected this to my Amazon Echo Tap and the problem happened, so I collected the log linked here:
https://www.dropbox.com/s/ets5njs6rrm8c1l/report_2017-09-18_111234.zip?dl=0
However, I had trouble reproducing this problem with several other Bluetooth speakers, if that is relevant. It did happen before I knew how to collect bug reports but I wasn't able to reproduce it on any Bluetooth except the Tap this morning.

I'm using google pixel, android 8.0. Mx player ver 1.9.8
Music stop playing when I press the home button.
I'm not connected to bluetooth.

After the recent update to MX Player Pro 1.9.8 I think all of the background play problems disappeared for me EXCEPT for when I am connected over Bluetooth to an Amazon Tap.
I have tried every combination (with no Bluetooth, Echo, Echo Dot, various generic Bluetooth speakers and the Tap) and I only see the audio in background problem when my Pixel XL is connected to the Tap.
The symptoms are the same and easy to reproduce. You can see the player still incrementing time in notifications but there is no audio. When MX Player Pro is brought back to the foreground audio starts playing again and the position in the MP3 has still been incrementing while MX Player was in the background.
I took another report from MX Player Pro, linked here (I can't put outside links because my account is too young, this is the rest of the URL without dropbox.com prepended...is there some other way I should do this?):

Hi,
Our developers already notified about the issue about the background play issue with remote streams. We will try to fix it ASAP.
You may set HW+ as default for network streams as a temporary workaround. HW+ & SW works as usual.

I wanted to follow up that any additional problems and weirdness with MX Player Pro after your initial fix have also been fixed by the Android 8.0.0 Security patch for October 5, 2017. Background play works for all cases I had issues with.

in developer option search DISABLE USB AUDIO ROUTING and turn it on

I can report that playback pauses on bluetooth speakers (Anker SoundCore Mini) on AIMP player as soon as the screen turns off, but it works well with LineageOS Music player (or so I think it works). Phone in question is Galaxy S5 klte
It worked well in 14.1, but not in 15.1 ofc
I will try the baba.yoga suggestion

Latest update, lost background play ability
Frustrating. App just updated and I lost background playing, settings still the same. If I uninstall the app and reinstall, I get background playing for a hour or so, then it disappears again.

This is caused by the new restriction when targetting the newer android SDKs. When the system force closes a foreground service (used to prevent it from getting killed when the device reaches low memory state), it can't be restarted again by the app itself. You have to completely force stop the MX. Then it will work again.
If it is possible, kindly collect the logs through ADB when the MX Player is getting killed by the system. It will help us to understand the issue.

Unswitchable subtitles while using HW Decoder

Hi there.
i am trying to watch movies on my MINIX Neo X8-H with the MX Player, but the problem is there are forced subtitles in different languages (in this example it is chinese/japanese subs on top - the bottom is mine. but sometimes it is in russian or other gibberish, but it happens to every single movie or TV series i turn on) and it only happening while i am using HW Decoder. but when i am switching to HW+ or SW Decoder they disappear. but the problem is that while i'm using SW or HW+, the video and the sound gets desynchronized after short time, (and it gets worse after a while), or if it doesn't (sometimes it doesn't) the bigger problem is HW+ & SW doesn't support surround mode, and i really like surround. so i am forced to use HW Decoder on my TV. Is there a way to either turn off the forced subs or to either use other decoders properly so the video and the audio wouldn't get desynchronized? Or is there a way to make HW+ or SW to support surround

We are sorry to bring you this inconvenience. Unfortunately, it is caused by the android media framework implementation on your device. Request you to open the accessibility settings on your device and disable the caption. That should fix your issues.
