WARNING: ActiveAE - large audio sync error on Netflix Plugin

[Vitocorl]

I opened this at CastagnaIT/plugin.video.netflix, but since then i found that peak3d has already dealt with similar errors in Kodi and inputstream, so i closed the issue at CastagnaIT/plugin.video.netflix and i am continuing here: The issue is that audio gets out of sync and video starts stuttering on Xiaomi Mibox S, Android TV 8.1 Addon version used plugin.video.netflix_0.14.0beta23_20190331. I also installed the latest Kodi nightly(kodi-20190402-f8100282-master-armeabi-v7a), as i realized that peak3d has provided a fix for a similar error happening after skipping forward a video file in Kodi, but it does not fix it for me.

The problem occurs at the same videos and at the same time of the video each time, for example, at Luce Cage TV Show, episode "Manifest" after 30 seconds of play. If i scroll backwards or forward the video then it resumes playing normally. I suspect it is some kind of buffering problem, but it only occurs on the Kodi Netflix plugin and not in the Android app. I am not sure if it is a Netflix plugin error or an inputstream adaptive error. I cleaned cache of Netflix plugin, but afterwards the same happens. I also used an optimised advancedsettings.xml, but i do not think Netflix plugin is using it.

My Kodi debug log is too big (2,2Mb) and hastebin does not accept it, so i am attching it as a zip here... kodi_debug_log.zip

@peak3d Is there a way to adjust the buffer memory size in inputstream? i think my advancesettings.xml has no effect whatsoever. Moreover, i still cannot tell if this problem is due to Kodi or inputstream, the issues have started since about ten days ago...

[Vitocorl]

@peak3d Any idea about this problem, it keeps happening, i have updated Kodi to the latest nightly with no effect...

[Vitocorl]

@peak3d I have just checked and when the problem happens i can see the buffer going down to 0%, as long as the buffer is over 0% (even if it is at 5%) the video plays smoothly, it is a buffering problem, but i do not know how to adjust it in inputstream....

[peak3d]

From log there is a A/V diff of ~ 8ms, what is not nice but should not be visible much. First I would try to switch screen to 59.94Hz and enable "Sync Playback To Display"

Before you send another log, pls. try to reduce log spam (maybe ask addon maintainer tio clean up things) or disable JSON rpc component debugging.

@peak3d Könnte dies auch das Problem mit dem DAZN Buffern sein, welches einige Leute (auch ich) haben? Es haben sich ja einige Leute im Kodinerds Forum darüber berichtet. Hab in einem alten Log auch die Warnung: 2019-03-08 14:42:14.644 T:1916896112 WARNING: ActiveAE - large audio sync error: -89455.525146

[peak3d]

DAZN is different from what I remember from last investigation, they have PTS jump ssues between segments. But - this is just a guess, I cannot reproduce because I don't have Dazn.

I will try to reduce the log, however, since the problem happens during playback, the log gets huge, i will disable JSON rpc component debugging and emby and hope for the best...

I have the same problem on kodi 19 ActiveAE - large audio sync error the log gets filled with this and at a certain point streaming stops and hangs kodi thank you

[ratcashdev]

Same issue, Kodi 19.1, only on specific streams and never on others (or it gracefully recovers).

[rafhtl]

Hi I still have the issue in version 19 large audio sync error filling my kodi.log Help! could you at least disable the warning log? WARNING : ActiveAE - large audio sync error: -1004.835002 thank you

[CrAcK75]

I've the same issue playing: https://supertennix-l3-live1.secure.footprint.net/restreamer/supertennix_client/gpu-b-c1-17/restreamer/rtmp/hls/h24_live/manifest.m3u8 I've a lot of WARNING : ActiveAE - large audio sync error: and also ERROR : CDVDAudio::AddPacketsRenderer - timeout adding data to renderer and WARNING : CVideoPlayerVideo::OutputPicture - timeout waiting for buffer as described here: https://github.com/xbmc/xbmc/issues/20089

Kodi only plays a few seconds and then stops the playback by freezing the image, in my case if I rewind a little AI it plays the video well but only for a few seconds, if I repeat the rewind it plays another couple of seconds and so on ... could i fix it or is a fix needed?

This happen on Matrix 19.3, IA 19.0.2

@CrAcK75 the same warning in the log != same issue.

Luckily I can access that stream from where I am, and whether it's played in Kodi, VLC, or Chrome there's an issue with the audio sync. It seems to be several seconds out. This could be causing the other symptoms seen or maybe completely unrelated. I can see from my log that inputstream.adaptive seems to skip over a segment after ~10 or so seconds so maybe there is something that can be done.

Thank you for your answer @glennguy, unfortunately, to date that streaming is not available, I think the site has some problems, but in the last few days if I was playing the streaming online there were no visual problems, only kodi freezed the image.

For now I've to wait

[glennguy]

@CrAcK75 fix is in progress, please see #878 Once backported to Matrix I will do a release

[CrAcK75]

Once backported to Matrix I will do a release

sorry for late but I had with high fever for a few days

on android seems to be ok but on Windows I continue to have very often a lot of WARNING : ActiveAE - large audio sync error there is another issue to follow?

[CastagnaIT]

what kodi version on Windows? can you try on Kodi 20? is a bit weird that happens ~only to you~ so rarely, from my tests i have also noticed that mentioned warning could happens when the system is too busy thing that however can not be solved

for example with my low end pc happens when i watch videos while the system install windows updates or do something else operations that slow down the system, so until it finishes the system updates operations i have to pause the video

No, I cannot try with Kodi 20, is not stable and I'm not interest until it become official, the issue is on Kodi 19 Matrix since 19.3 and it's not only my issue because we have an addon "WLTV" that groups a lot of free tvchannels and, many users has the same issue "ActiveAE - large audio sync error". Many of them (not all) has solve on a lot of channels with android (because on android now there is the 19.0.3 of InputStream) but the others has still issues. It's difficult to reproduce the issue because not many channels has a simple fixed url to the stream and also it's not a static issue I think it depends by stream.

[CastagnaIT]

however i have tested your link of test stream on: android honor with Kodi 20 windows with Kodi 19 and Kodi 20 and in all cases the stream is played correctly

ensure you have in kodi video settings: hardware acceleration mediacodec surface -> ON hardware acceleration mediacodec -> ON sync playback to display -> OFF

this warning "ActiveAE - large audio sync error" not explains nothing on kodi repository there are a lot of Issues opened (of different nature) that report that warnings

your problem appear a bit different, the author of this Issue thread say:

The issue is that audio gets out of sync and video starts stuttering

instead you have reported this:

Kodi only plays a few seconds and then stops the playback by freezing the image

the only way to try investigate is to have a test stream where we can reproduce the same issue from other devices but it is better that you open a your Issue thread, by providing also the test stream

[CastagnaIT]

also be reluctant not to do a test on Kodi 20 not help us to investigate, the core of Kodi 20 and InputStreamAdaptive for Kodi 20 has different changes/fixes/improvements therefore it will not be possible to tell whether the problem has already been solved
