After upgrading to 6, can't play video on web anymore

[ultranol]

Problem Description: Trying to play video on a browser won't work after upgrading to 6. As soon as I click on the link of a video, and the player starts, on Firefox and Chrome a blank cover shows up with an URL like this: http://localserver:4040/hls/hls.m3u8?id ... tRate=3000 - on Safari there are three dots that keep blinking and the video is never played.
Troubleshooting Steps: I looked over the transcoding options and I'm using the recommended mp3 audio and streaming definitions.
Playback Application and version: Chrome 55, Firefox 42, Safari 10.0.1
Subsonic Version: 6.0 (build a7857c) – April 30, 2016
Server Version: jetty-6.1.x, java 1.8.0_91, Linux (80.6 MB / 135.0 MB)
Hardware Platform: Ubuntu 16.04
Java Memory Limit: not sure
Problem Filename: all videos produced by my security camera. They are of the MKV format. Other MKV files that I have play fine but these definitely played fine as well. The upgrade was the only thing that changed since then.

[toolman]

Hi,
Searching Google for "Invalid UE golomb code", it seems that this is a bug in ffmpeg.
Perhaps it makes sense to download another version ( http://www.ffmpeg.org/download.html) and replace it in the "Transcode" folder?

[ultranol]

I've installed the latest ffmpeg (the version distributed for Ubuntu is 2.8.8 and I've followed the compilation instructions to get the latest one from the 3.0 version):

You can see the previous error is gone.

I have renamed the ffmpeg on /var/subsonic/transcode/ to something else and placed the new one there. Restarted subsonic. Unfortunately, nothing changed, the error persists.

[toolman]

Another suggestion:
Download the previous version of Subsonic and use the ffmpeg-prgram included in that realease.
Or is there a possibility to have your securitycam encode the video in another container like mpeg or mpg?

[ultranol]

Nothing... I downloaded the package from Sourceforge and the version is yet different than both the one I had when I realized the problem and the one I compiled earlier.

Other than the extension, I don't know how to figure out how my security camera-generated files are encoded...

[toolman]

Did some more googling:
http://stackoverflow.com/questions/1473 ... d#14731853

[ultranol]

Yeah, nothing... I replaced the recommended HLS setting:

ffmpeg -ss %o -t %d -i %s -s %wx%h -v 0 -b:v %bk -maxrate %bk -bufsize 256k -flags -global_header -map 0:0 -map 0:%k -ac 2 -f mpegts -c:v libx264 -preset superfast -c:a aac -b:a 96k -strict -2 -threads 0 -copyts -

with the one on the link, switching the input file to %s:

ffmpeg -ss 0 -i %s -filter:v scale=640:480 -b:v 21504 -t 5

Nothing changes, same problem.

[toolman]

Can you play the MKV-files with a program like VLC or any other mediaplayer?
You could try to re-install the previous version of subsonic to test if that solves the issue.
Since you say that the problem is only with the MKV-files from your security cam it seems to me that there might be an incompatibility in the way the MKV-files are generated.

[ultranol]

It works when I completely remove everything and install 5.3 from scratch. By the way, I found some other MKVs, not from my camera, that can't be played as well, for some reason.

Sucks that I will have to forfeit all the most played/ratings info since I'm starting from scratch... do you know any way to import it?

Thanks for the help.

[toolman]

I don't know for sure where all this information is stored but if you still have following folders from your previous installation you might be able to restore it:
DB-folder , db.backup, jetty, Lastfmcache , lucene2. thumbs, and the properties-file.
These folders should all be in your Subsonic-folder.
Sorry I can't be of more help.

[ultranol]

Mystery solved.

I realized the transcode settings on the 5.3 is different... it comes out from the box like this apparently. There are commands for other types of files, not only "mp3 audio". For example, there's one for "mkv video" which is:

ffmpeg -ss %o -i %s -c:v libx264 -preset superfast -b:v %bk -c:a libvorbis -f matroska -threads 0 -

I simply added this to the 6.0 installation and it worked.

Thank you again!

[toolman]

Great to know that it works now. Thank you for solving the mystery and for sharing.
