Topic: Pressing Stop when watching Movie returns to backdrop screen but MC is frozen (Read 6375 times)

CountryBumkin · « **on:** July 07, 2013, 03:34:13 pm »

I have seen this on both computers now. When I stop a movie (with remote or using mouse on the play-bar) the movie stops and returns to the movie backdrop (DVD cover shot) but I can't get MC to do anything else. I can move the mouse pointer around but can't return to menu or restart movie.
I have to cntrl+alt+del and kill MC with the Task Manager. I am on version .206.

Could this be same problem reported here http://yabb.jriver.com/interact/index.php?topic=81789.0

to update - I find this problem also occurs after watching/stopping recorded TV Shows.
I did more testing and the problem does not occur every time. I was able to stop some movies and MC returned to the menu as it should. Its seems like the freeze occurs if I stop quickly/soon after starting to play. When I played 5 minutes or more into the show/movie then stopped, MC worked properly. I was only able to test with about 8 movies (on two different client machines) 6 froze, 2 worked properly. Also Netflix worked properly.
I created several logs, but I don't think I'm catching anything after the freeze.

I guess I'm the only one seeing this. Someone please test this for me. Start a movie (I'm using ifo (vob) movie) play it for about 1 minute (or less) then hit the stop button on your remote. Does your screen freeze? I can reproduce this problem on two different sets (both clients). Is it just my setup?
Once MC freezes on the cover art, I have to kill the program and restart.

It's working fine here, using a DVD disc.

Stop or Pause?

CountryBumkin · « **Reply #5 on:** July 09, 2013, 08:37:45 am »

Stop.

I seems that if I let the movie play for a while (usually I play to end) and then Stop it, everything works fine. But if I start the movie then Stop it within a minute of two (like I selcted the wrong movie) it freezes MC.
Thanks for checking. If no one else is seeing this, it must be an issue with my setup.

The logs don't clearly show a stop / switch UI mode / hang flow. So I'm not sure what's happening.

However, please see if Red October Standard vs HQ makes a difference.

Let us know what you find.

CountryBumkin · « **Reply #7 on:** July 09, 2013, 10:41:45 am »

I tried both RO std and HQ, same issue. You mentioned in another post (Crash on Stop) that an audio setting might cause a problem on stopping playback, so I check this out next.

It does seem that the problem occurs when the movie is started and stopped within a minute of so, but I did not see this issue when playing the movie to the end (not sure if this is true all the time, but it does mean it takes a lot longer to test the various scenarios).

I can reproduce this problem - but I haven't tested all the setup/configuration possibilities yet. Too bad the log doesn't show anything.

CountryBumkin · « **Reply #8 on:** July 10, 2013, 08:02:17 am »

New info -
I am still having this problem, and it does seem that if the movie/show is stopped within a minute, or so, of starting playback it will freeze MC. But if I let the movie/show play for 10+ minutes, it will not freeze MC. Could there be some communication between clients and server that takes some time to occur?

Also, maybe related, I see that the queues in madVR are running very low or empty on a couple of them. For example on the Server the queue will be like 16-26/32 but on my client (same movie) the queue is like 0-1/16. Sorry I should have brought my notes on this to work. But the general idea is that I'm seeing low queuing ("0-1") on my Client machines (both). I'll post back the exact queue names and vaules - if someone thinks it is relevant.

And the Server doesn't freeze MC when I hit the Stop button after a couple of seconds of play.

So maybe the issue is with the network.

JimH · « **Reply #9 on:** July 10, 2013, 08:39:34 am »

What happens if you use RO Std?

CountryBumkin · « **Reply #10 on:** July 11, 2013, 07:11:25 am »

I still have not figured out what is causing this problem - maybe the installation of the next MC update will take care of issue. Maybe something didn't install right.

Jim,
the problem is same whether or not I'm in RO-STD or RO-HQ. I tried different Audio setup too.
Testing with the same movie - stopping after a few minutes locks up MC, playing for 30 minutes then stopping, MC returns to menu.
This happens on all three client machines but does not happen if I play movie from Server computer. So it seems like it is a network related issue or a Client setup issue.
______________________________________________________________ ?
On the subject of MadVR queues (maybe a clue).
When I play a m2ts (VC-1) 1080x1920, 23.976fps movie using RO+HQ (on Client machine) the queues are full and stay full (decoder 31-32/32, renderer 23-24/24, present 15-16/16, etc.),

but when I play a DVD rip (ifo-vob) which is 29.9fps 720x480 resolution, the MadVR queues are "split queue 1-6/24, render queue 1-3/24, present queue 0-3/16, and frames dropped: over 1000 and climbing).

Since the queues on the m2ts rip (Blu-ray) stay full and no frames are dropped it does not appear to be a network/streaming issue. I think is something in the MadVR (or MC) settings that is wrong for playback of DVD material. Any ideas what I should look for?

nachoville · « **Reply #11 on:** July 20, 2013, 08:14:34 pm »

I'm experiencing this exact same behavior on .206 as well. Pressing Stop after some videos causes the application to freeze, sometimes displaying the backdrop and at other times just a black screen. The application doesn't crash, Task Manager lists it as "Not Responding" and it must be manually restarted.

Client / Server configuration
RO+HQ (haven't tried standard yet)

I tried reinstalling MC, but it unfortunately didn't have any effect. Log files are attached.

CountryBumkin · « **Reply #12 on:** July 21, 2013, 06:33:57 am »

I have not solved the problem either. I thought installing the latest MadVR and/or LAV versions would fix things, but it has not. I don't think this is an MC issue (or many others would have reported it by now). But hopefully the experts at JRiver and on this Forum can help figure this out.

It seems that if I watch a movie for at least 5-10 minutes then STOP it, no problem, MC goes back to the menu. But if I start a movie and then STOP it within a few minutes it freezes MC (same as your description) and I have to Cntrl+Alt+Del to "end" MC. If I hit the "Windows Key" I can open other applications (meaning computer is not frozen - just MC stops responding). The Log doesn't seem to capture anything.

I'm still trying to find the exact conditions/time that things fail. Yesterday I tried watching a Blu-ray rip and I got about half way through it when MC just stopped (is this a new problem or the same issue?). MC displayed the Cover Art screen and became unresponsive. I'm playing the same movie again on a different computer right now to see if it is computer- movie- or maybe a networking issue. Since this problem is easy to repeat I should be able to log the exact conditions when it happens.

cncb · « **Reply #13 on:** July 21, 2013, 06:58:31 am »

I reported what sounds like the same problem on the beta board. For me, it only seems to happen when I am streaming a local file on the server. That is, if I change the path of the file in MC (on the server) to a network location that can be resolved on the client so it can play it directly, it stops fine and there are no lockups.

CountryBumkin · « **Reply #14 on:** July 21, 2013, 01:43:55 pm »

What do you mean by "changing the path of the file to a network location that can be resolved"? Are you just saying it works on the Server?

I know I can play a movie from the Server without issue. The problem is happening when I play from the Client (stream to client). To me, this says there is a problem with my network. I have not changed anything regarding my network settings - but that doesn't mean something didn't change/break on its own.

I mean change the path in the MC library to a network location instead of local (e.g "\\SERVER\Videos\Video.mkv" instead of "C:\Videos\Video.mkv"). So, when you have "Play local file if one that matches library server is found" enabled on the client it will play the file directly instead of streaming it. I have the lockups on the client when it is a local path but not when it is a network path being played directly.

nachoville · « **Reply #16 on:** July 21, 2013, 02:59:43 pm »

Under Playing From, my client shows as connected to a "library server" instead of a "local library". I'm unsure how you could modify the path to the files from local (C:\path\file) to a network/UNC path (\\server\path\file) when connected this way.

The part about "starting and stopping within a few minutes" rings very true for me as well and it may be the key to reproducing the problem. It seems to work flawlessly under normal circumstances, but as soon as you stop a video shortly after it has started it will sporadically lock up.

I don't believe it to be network related as I'm hard-wired and don't need to reboot or intervene with my router/switch to resolve the problem. My library server is dual-homed so I may connect it directly to the client in order to eliminate the router and switch from the equation. Granted even this won't resolve some oddball issues between network cards.

I'd really love to figure out what's going on here. I've sorted out 99% of the other issues I've had, but can't keep my client from locking up on occasion.

Same here. I don't reboot or reset anything - just close the non-responsive MC program and restart it. Since it only seems to a problem on the client - it seems logical that it is somehow related to streaming/networking.

You open MC on the server and change the path there.

I captured a mini-dump from the most recent application hang.
The WinDbg analysis of the crash is listed below. Hopefully it will shed some light on what's happening...

Thanks cnbc for the suggestion. I took a slightly different approach; mapping drives from the client instead of switching to UNC paths on the library server.
As an added bonus the Theater View UI is much snappier and more responsive now. Most noticeably when navigating folders and skipping through a video (progress bar is fluid instead of moving in large chunks).

Here's the workaround in some more detail...

On the client PC, map a drive (right-click on My Computer > Map Network Drive) to the media server so the folder structure used by the server library matches the client. --> \\server\e mapped to E: on the client. Now E:\folder\filename.avi is a valid path on both the server and client.
MC > Options > Media Network > Client Options. --> Ensure "Play local file if..." option is checked.

I also left the "Auto Sync with server" option checked and was able to save a new playlist to the server so at least some client/server operations are working fine. Looks like this (apparently rare) issue is specific to rapid file playback changes via the Library Server.

Hope this helps. Cheers!
