>= 2.3.0 faulty decoding with almost complete green screen #1569

Closed abuisine closed 8 years ago

abuisine commented 8 years ago

500+ videos were working fine with 2.2.0. The video produces, right from the beginning, green screen during the full playback, even after a seek, with rare jerky artifacts of the video. A simple reload of the page usually solves the problem. This occurs randomly. A video that finally play correctly after a reload will never fail again.

The video is rendered as a webgl texture, which complexifies the debugging a lot, but again the problem disappear when rolling back to 2.2.0

Environment

All videos reports a problem through the validation tool (but again this was working perfectly in 2.2.0):

### error: ftyp-1 
### The brand 'isom' can only be a compatible, not major, brand
### error: moov-1:trak-1:mdia-1:minf-1:stbl-1:stsd-1 
### Validate_AVCConfigRecord: -2020
### error: 
### 'sidx' found for self-initializing media, violating Section 6.3.5.2. of ISO/IEC 23009-1:2012(E): The Indexed Self-Initializing Media Segment ... shall carry 'dash' as a compatible brand. 
WARNING: unknown file atom 'mfra'
### error: 
### Buffer underrun conformance error: first (and only one reported here) for sample 1 of run 1 of track fragment 1 of fragment 7 of track id 1 (sample absolute file offset 726040, fragment absolute file offset 724496, bandwidth: 448002)

The streams have correct Access-Control-Allow-Origin headers (CORS) There are no network errors such as 404s in the browser console when trying to play the stream The issue observed is not mentioned on https://github.com/Dash-Industry-Forum/dash.js/wiki/FAQ I did not succeed in my tests to reproduce the problem with the latest reference client on http://dashif.org/reference/players/javascript/

It's pretty poor form not to warn people that this is adult content.

That said, I don't see the errors you describe.

A simple reload of the page usually solves the problem. This occurs randomly. A video that finally play correctly after a reload will never fail again.

Even if you clear the cache?

There was a change around self-initialising streams in 2.3 but this should only affect manifests which do not signal indexRange. The behaviour around reloading probably implies this isn't causing the problem anyway.

abuisine commented 8 years ago

Sorry for the adult stuff, I have a test video produced through the same encoding farm here

Might be linked to a cache problem as the problem disappears until I wait a day and launch a new run of tests.

The first time is faulty, and

if I reload the problem disappears.

Just had it on this one

I am attaching a picture of the result, looking at the bottom of the 3D scene (which is a semi sphere), the video is a cubemap projection so you can infer the cube faces screen shot 2016-09-05 at 12 28 30

[22349] Native video element event: pause
abuisine commented 8 years ago

Ok, seems to be a wrong init on my part

I have the video element being created and initialized before attaching it to the dash player.

The video.src was set with the manifest, and almost immediately after (in a child class constructor) the dash initialize() was called with the video element and the same src. Of course this is not good for a couple of reasons:

In any case, when reloading, I suspect that there is much less delay between both initialization which makes the video and dashplayer init to collide differently, which makes the dash player to run correctly (no green screen).

So I corrected my code and now avoid to set src to the video element, which seems to solve everything.

I'll close the ticket in a couple of days, once I got sufficient logs and stats to confirm all this !

PS: I even tried to set video.src to null, which caused the same issues (green screen).

abuisine commented 8 years ago

Bad news, I still have the problem.

If I bind the video element as a normal 2D canvas, I see a kind of green blinking screen which alternates between the following two kind of frames: screen shot 2016-09-06 at 18 50 33 screen shot 2016-09-06 at 18 51 08

I can play pause seek etc ... no problem, but it stays green

dsparacio commented 8 years ago

Are you using Ref player to reproduce this issue? If so, can you open the Show Options Tab and uncheck Fast Switch to see if anything changes. just want to make sure that is not the case.

bwidtmann commented 8 years ago

The disabling of the "Fast Switch" feature is a really good hint, as I experienced those "green screens" mostly when the init fragment has not been appended to source buffer correctly before switching video quality levels. So you have to ensure that BEFORE any video chunk is appended to source buffer, its corresponding init frame has to be appended before, otherwise the video decoder gets wrong metadata and therefore is not able to render the frames correctly.

abuisine commented 8 years ago

Very good point indeed, I actually do change the quality level just after initialization based on user configuration (cookies), let me do a run of test today !

abuisine commented 8 years ago

I am not able to reproduce the problem on the reference player.

But looking at my code, I set a quality as soon as streaminitialized is triggered

this.player.on('streaminitialized' ...

if user has quality set as auto

this.player.setAutoSwitchQualityFor('video', true);

if user has a specific quality value

this.player.setAutoSwitchQualityFor('video', false);
this.player.setQualityFor('video', quality);

During all my previous tests (from the posts on this page) I had my user setting at maximum quality value.

my player init is as follows:

this.player.initialize(this.v, video_s, false);
this.player.getDebug().setLogToBrowserConsole(true);
this.player.setStableBufferTime(20);
this.player.setTrackSwitchModeFor('video', 'alwaysReplace');

I did a few tests here and it seems to confirm that setQualityFor just after initialization makes the decoding fail (from time to time) as I never saw the problem when auto switch quality is on.

Fast Switch

I did another run of tests with setFastSwitchEnabled to either true or false, and quality always set to highest value, like this:

this.player.initialize(this.v, video_s, false);
this.player.getDebug().setLogToBrowserConsole(true);
this.player.setStableBufferTime(20);
this.player.setFastSwitchEnabled(false);

And I got decoding failures, from time tot time, in both cases.

@bwidtmann we insure init before media chunk fast switch will not affect that. But if a media chunk is inserted at a point that the playhead has elapsed, then you may get some odd artifacts. That is the tricky part. @abuisine are you fairly confident that fast switch is not your issue. Sounds like it is happening either way. I will take a deeper look at this today.

abuisine commented 8 years ago

@AkamaiDASH I can only talk based on the tests I made, and unfortunately there is a lot of noise on my page (WebGL, js, etc ...) What I am sure about is that I saw the decoding problem with fast switch being set to false, at least a couple of times. As soon as I get a bit more time I will try to build the simplest page that reproduces the problem.

dsparacio commented 8 years ago

Great thanks for confirming you saw same issues with and without the feature enabled. You should be able to set right at stream init event the auto switch state and quality. I do something close with the ControlBar.js in contrib lib. That fact that you can not produce this in our player may point to something in your page that is causing the issue.

dsparacio commented 8 years ago

I have a feeling this is not an issue in Dash.js but want to make sure. Seems like related to specific setup/player. @abuisine please reopen with an update if you feel this should stay open.

abuisine commented 7 years ago

I was able to reproduce the problem with 2.4.0 on my setup, will check with lighter webpage

trakout commented 7 years ago

@abuisine I just had this same issue -- have you tried setting quality inside 'BUFFER_LOADED' instead of 'STREAM_INITIALIZED'?

abuisine commented 7 years ago

Nope I just tried the 2.4.0 and had the same problems, I am working on VP9 encoding to see if the problems persists.

It might be linked to high resolutions, I am @ level 5.2

@abuisine Did you find a solution for this issue. I have the same problem with DashJS v2.9.2 where i get green artifacts when I seek to different timestamp while player attempts to switch quality (also happens when i switch quality manually and seek to different position immediately). I tried this with both enabling and disabling the "fast switching", resulting same issue.

iamprem commented 5 years ago

After looking at the logs produced, it looks like the onPlaybackSeeking method in ScheduleController is aborting the Init Fragment request made by the quality switch request when the two events happen very quickly in order to support faster seek response.

You can see on line 36857 it is loading video_5 and later on line 36862 the quality change is triggered to load video_4 fragment url. But if you look even further on line 37013 the init fragment request for video_4 is aborted to support faster seek.
