Subsonic Forum

Problem Description: Subsonic has serious issues playing videos in both the external and internal Flash player.

• Internal Flash Player: After a certain period of time, the video becomes increasingly choppy during playback (even when buffered so I'm not so sure it's an issue with the speed of the server) to the point where it freezes the browser and requires the browser's process to be terminated manually.
• External Players: When trying to open the video using VLC or Windows Media Player, both players return an error and are unable to open the stream

Troubleshooting Steps: I originally tried using the stable version of Subsonic 4.5 but then updated to the newest version of Subsonic and restarted the server after ensuring that it was not using SSL. I've also used multiple browsers to play the videos (Chrome, Firefox, IE 9)

Playback Application and version: Flash 11,1,102,55, VLC 1.1.11 and WMP 12

Subsonic Version: 4.6.beta2 (build 2566) – November 16, 2011

Server Version: jetty-6.1.x, java 1.6.0_29, Windows 7 (66.3 MB / 96.7 MB)

Hardware Platform: Core 2 Duo E6600, 4 GB RAM, Windows 7

Java Memory Limit: 100MB (also tested with 256 MB)

1st thing I would try is upping the SS memory limit (try 256MB)
Depending on the power of the client machines you could disable the video transcoding for the external players and just stream the raw file.
Then let VLC or WMP do any transcoding that may be required.

Disabling transcoding gets me these errors in VLC (after upping the memory to 256 MB)

Also, Seeking within the video in the flash player does not work either. It simply stops playing back the file.

Are you using external player or external with playlist? (I find in testing the latter works better and allows seeking)
That video does play ok in vlc directly I presume ?

I've tried both options and it still doesnt work. The flash player choppy symptoms appear about 18-20 minutes into any video (regardless of format or encapsulation)

What version of flash?

I'm running 11,1,102,55 (should be the latest version right now)

How does your version of flash play other movies from other sites?
Maybe your having display driver issue?

I don't have problems playing flash videos anywhere else and even flash issues wouldnt explain the issues playing in external players.

I've since been manually setting up streams using VLC on both ends and it has been working very well with transcoding so the hardware is fast enough for it.
