[SOLVED] Playback in Firefox/Chrome Fail | Edge Success


Zalaare

Recommended Posts

Preface

All of the media I'm testing have previously worked flawlessly in the current environment.  Meaning my network topography/speed has not changed.  I cannot say for sure when this problem began as I rarely need to use a browser to access my Emby personally, however I had a user report issues a few weeks ago.  I gave it very little thought until I had reason to use a browser recently and I ran into problems.

 

Problem

Recently (within the last few weeks), Emby playback within my web-browser has begun giving me the following error:

Testing

I have tested with various browser on various machines with results as such

Ubuntu - Chrome: FAIL

Windows - Chrome: FAIL

Ubuntu - Firefox: FAIL

Windows - Firefox: FAIL

Windows - Edge: SUCCESS

I have deduced that this happens for all Matroska contained media as far as I can tell.  Container WebM w/ VP9/Opus codecs works correctly.  I'd have to really go fishing for other types of media to test as my libraries are 99.99% Matroska or WebM.

 

Logs

NOTE: Firefox actually attempted transcoding, though still resulted in the same error.  I zipped the result transcode logs for each occurrence, though I know they will not be helpful for debugging this.

UPDATE -- 20180927 -- Official Embyserver Docker Container results --

UPDATE

It appears I may have opened a duplicate post from someone else with a similar problem (though to be fair, when I searched I did not find it as their topic is very misleading) https://emby.media/community/index.php?/topic/63309-docker/?p=627055

Also at a glance at their log, their ffmpeg doesn't even start, whereas this is not my issue.

I rebuilt my Nginx setup approximately around the same time as this problem started happening so I'm wondering if this may be a reverse proxy issue.  None of my other proxies seems to be having an issue, and everything in Emby works as expected except this playback in Firefox and Chrome, so I honestly haven't given it much thought until now.  I'll spend some time going forward experimenting with the config to see if I can figure if this is where the problem is.

Okay for anyone who finds themselves with a similar issue, I found the broken clauses of my Nginx config.

 

I had to remove the following clauses from my setup.  I do not have enough nginx-fu to rewrite them so they work:

add_header Content-Security-Policy "default-src * data: 'unsafe-eval' 'unsafe-inline'" always;

location ~* \.(?:css(\.map)?|js(\.map)?|jpe?g|png|gif|ico|cur|heic|webp|tiff?|mp3|m4a|aac|ogg|midi?|wav|mp4|mov|webm|mpe?g|avi|ogv|flv|wmv)$ {
expires 7d;
access_log off;
}

location ~* \.(?:svgz?|ttf|ttc|otf|eot|woff|woff2)$ {
add_header Access-Control-Allow-Origin "*";
expires 7d;
access_log off;
}
