Chromecast aspect ratio wrong

Recommended Posts

I am facing an issue when trying to play some video content recorded with a Hauppauge HD-PVR box. When trying to playback the content, the resulting image has the wrong aspect ratio (sorry for the large size)

 

58543135f0f5a_IMG_20161216_131726.jpg

 

In order to try to resolve this, I configured folder sync and marked these shows to sync with the high profile. No joy.

 

So in order to provide an example here, I cut out 1 minute of the video and played it to ensure that the problem was still there. I used ffmpeg for the task, with an option like this

ffmpeg -ss 00:00:00 -t 00:00:00 -i [input.mp3|.mp4|...] [ouput.mp3|.mp4|...]
Well, there was no issue playing the file... so I wonder what sort of magic ffmpeg had done and looked at the content with MediaInfo

 

This is the original file

With the fast approaching holidays, it would be nice to get a resolution so I could do some binge watching.

 

I have pasted parts of the log here when starting the stream. It's for a different file, but the pattern is exactly the same

Can anyone help with this?

Existing files are >8gb so they would not be practical. I will try to record a smaller sample over the weekend, as cutting out portions of these files resulted in a working cast...

 

note that the main difference between the 2 files seem to be that the "cut" file is "progressive" as opposed to interlaced. Furthermore, folder sync also shows "interlaced" as well.

 

this leads me to believe that the issue might be caused by Chromecast not properly recognizing the interlaced stream that is sent to it...

I am sharing a short example which shows similar behavior, although a bit different. The picture is "compressed" at the top of the screen and the bottom section is filled with artifacts which remind of old TVs when they got "ghost" images from reflections of the signal.

 

As for the content, this is whatever was playing during the record, not a choice ;)

Arrgh.... looks like this is getting worst and worst. 
 
I wanted to reorganize some media on my network file server because I was running out of space on one of the drives. This was a bad move. I ended up having to delete the sync folder which had been transcoding for 5 days now because sync jobs would all fail. I removed the plugin, reinstalled it and attempted to sync again.
 
There are exceptions now in the log, but overall, I think the sync jobs are running... will check in a few hours

	Application directory: C:\Users\myself\AppData\Roaming\MediaBrowser-Server\System
	System.InvalidOperationException: Unexpected ProfileConditionType
	   à MediaBrowser.Model.Dlna.ConditionProcessor.IsConditionSatisfied(ProfileCondition condition, Nullable`1 currentValue)
	   à MediaBrowser.Model.Dlna.StreamBuilder.GetVideoDirectPlayProfile(VideoOptions options, MediaSourceInfo mediaSource, MediaStream videoStream, MediaStream audioStream, Boolean isEligibleForDirectPlay, Boolean isEligibleForDirectStream, List`1 allMediaStreams)
	   à MediaBrowser.Model.Dlna.StreamBuilder.BuildVideoItem(MediaSourceInfo item, VideoOptions options)
	   à MediaBrowser.Model.Dlna.StreamBuilder.BuildVideoItem(VideoOptions options)

My guess is that the file that's being analysed by the sync job chokes on the content. This is also a file which was recorded by the HDPVR

Is there a way to send it to you privately? I don't like exposing my server structure to the general public.

 

FYI, folder sync should handle exceptions nicely when it's processing the video items in the queue. Not doing so results in the queue hanging out there and the temp transcodes to fill up the work drive.

 

I have cloned the repo to try and debug the process right before it derails; it would be nice if the condition evaluation could also dump which condition was unexpected, but short of this now I'll trace manually.

Hi @@sle118, I tested your sample file and it worked fine for me, both with transcoding and with direct play. the aspect ratio looked fine and the video filled the screen. Did you make sure the problem was occurring with the sample you gave me?

@@sle118, i tested this 4gb file on chromecast and did not see any aspect ratio issues, both with direct play and transcoding. What kind of TV do you have?

 

I will now test it on android. Thanks.

The sync issue is resolved for the next release, thanks.

 

Can you share your findings?

 

Also, I ran ffprobe on the command line and found the following output, which seems to be the root cause of many of my issues. -- NEVERMIND THAT. The file had been truncated to 0 bytes.

If you're on windows then you should just stick to the build that came with the server. you can grab it here if you need to:

https://github.com/MediaBrowser/Emby.Resources/tree/master/ffmpeg/windows

 

There is probably nothing wrong with the version that you chose, but it's not realistic for us to test every possible version so customizing it is generally only something you should do if you actually have a reason to do that.

I took the latest build and tried to sync again.  Saw the following exception in the logs

 

Constraint: NOT NULL constraint failed: SyncJobs.ItemIds
SQLitePCL.pretty.SQLiteException: Une exception de type 'SQLitePCL.pretty.SQLiteException' a été levée.
 
I added the logs to my shared folder. 
 
How I did this:
- I moved the video file to a folder where auto-sync was enabled
- ran sync
 
 
Note that the movie had been added to another sync job in the past, under a different "batch" of multiple movies. I had cancelled it when I found it to derail the entire sync job.
 
thanks!

Got it!

 

I sent another video file to the shared folder. That is the original file, full length, for which I posted the picture in the first post.

 

As for the aspect ratio, I'm playing the file on a 65" Haier LCD bought last fall. Other full HD content, for example from Netflix, plays just fine on the cast. I'll check to see if the chrome cast's resolution or sync rate can be changed. This wouldn't explain why I'm getting green interlaced video on the tablet, though.
