    Exclamation Serious bug in Stream play

    Not sure who to report this to but I have discovered a rather serious bug when creating a stream within our application.

    Essentially, it comes down to this:

    Stream testStream = Stream.createInstance(inVHost, "XXXXX", "testStream");
    boolean rc = testStream.play("completeLoadOfCrap.mp4", 0, -1, true);

    Two things happen:
    i) the "play" command returns true on a bad file pointer (ie, rc = true)
    ii) it generates MB of log entries within seconds and doesn't seem to stop.

    Specifically, here is the message:
    2016-02-16,17:59:20,EST,WARN,server,comment,-,MediaCache.createNewCachItem: Cannot find MediaCacheSource for (completeLoadOfCrap.mp4).
    2016-02-16,17:59:20,EST,WARN,server,comment,-,MediaCache.createNewCachItem: Cannot find MediaCacheSource for (completeLoadOfCrap.mp4).
    2016-02-16,17:59:20,EST,WARN,server,comment,-,MediaCache.createNewCachItem: Cannot find MediaCacheSource for (completeLoadOfCrap.mp4).
    2016-02-16,17:59:20,EST,WARN,server,comment,completeLoadOfCrap.mp4,MediaReaderH264.open[1]: java.io.IOException: MediaCacheRandomAccessReader.open: Item not in cache: completeLoadOfCrap.mp4: java.io.IOException: MediaCacheRandomAccessReader.open: Item not i

    At the very least, the play command should not be returning true. I encountered this because I was mistakenly referencing an S3 resource with it's absolute url (versus using mp4:amazons3/) and once that was done, everything works fine BUT I decided to investigate further and discovered playing pretty much any arbitrary bad stream generates this. I have also tried setting the stream to not repeat and no difference.

    Also, Wowza version: Wowza Streaming Engine 4.4.0 build17748

    Please contact me if you need any more details or if I have done/missed something entirely.

    I think a bit more information is going to be needed to sort this out.

    Please open a ticket by following these steps.

    Thank you,
