Error processing "progressive" jpegs

[BJamin99 0]

I have movies that have "progressive" jpegs in their folder for album art. Here is the "file" output for them:

 

Test Movie.tbn: JPEG image data, JFIF standard 1.01, resolution (DPI), density 72x72, segment length 16, progressive, precision 8, 2000x3000, frames 3

 

When the web interface requests these files I get the following in the log:

The response is the full-size original image.

 

If however I convert the jpeg to "baseline" with the following command:

 

jpegtran -copy all Test Movie.tbn > Test Movie.tbn

 

The "file" command then reports the following:

 

Test Movie.tbn: JPEG image data, JFIF standard 1.01, resolution (DPI), density 72x72, segment length 16, baseline, precision 8, 2000x3000, frames 3

 

And the log contains the following:

2017-04-17 13:20:11.7807 Info HttpServer: HTTP GET http://192.168.1.99:8096/emby/Items/153d96cc9fafffdd3982d256feed7d61/Images/Primary?maxHeight=360&maxWidth=240&quality=90. UserAgent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0

And I get the scaled image as a response.

 

Is it possible for Emby to support processing of "progressive" jpegs?

 

I must note that this is low priority as the web browser is able to display the "progressive" jpeg in the correct resolution. It just increases the bandwidth necessary for the interface and the number of errors in the logs. Also as a work around I can use jpegtran to convert images to "baseline".

 

Thanks.

 

FYI I submitted this as issue #2583 at github.

Hi, thanks for the report. We'll have to see why ImageMagick is choking on it, and/or if our usage of ImageMagick needs to be adjusted for these files.

Hi, I have the same issue on Debian.

hi @@toshi24, can you please tell us the exact issue that you're having? thanks !

jfif images will be supported in Emby Server 4.3. Thanks.
