5.1.4 web video: java.lang.NullPointerException

[michaelt]

Play a .mkv video with a stock (no mods) build of 5.1.4 to Chrome:

Code: Select all

INFO  18:48:16.834 [Thread-69] Exception in thread "Thread-69" java.lang.NullPointerException
DEBUG 18:48:16.835 [StartPlaying Event] The full filename of which is: /Users/umsmkv/aML/Video/Index/1-DVD_Black_Frame/HFRO.mkv and the address of the renderer is: 10.0.1.50
INFO  18:48:16.835 [Thread-69] 	at net.pms.remote.RemoteUtil$1.run(RemoteUtil.java:105)
INFO  18:48:16.836 [Thread-69] 	at java.lang.Thread.run(Thread.java:745)

Metering the code shows it may be related to transcoding to ogg (failing?? or bug??) and an unprotected reference in RemoteUtil.java:105

Code: Select all

                        try {
                            in.close();

A null check avoids the fault (and attempting to read) but the video still does not play in html5 mode.

This is a snippet of the debug.log around it in another run:
