VLC Hangs When Jump Ahead More than Once

by gaucherre / December 9, 2016 6:47 PM PST

Although i've been able to answer some computer questions for others, this one has me stumped. We like using VLC media player to play back TV shows that we've recorded using Windows Media Player. When we use any of the Jump Ahead or Back controls to jump one interval it works great, no problem. If we ask it to jump two intervals it freezes for about 10 seconds then makes the second jump. If we ask it to do three Jumps the freeze time is longer.
On other computers in other rooms (som wired and some on wi-fi) we can access those same recorded shows over our home network, and there's no freeze time at all when we request multiple jumps. I mean, you'd think if there's a delay skipping ahead 60 seconds or so then it would happen over a network and not on the pc where the shows are recorded!
Also, please note that if we play back using Windows Media Center there's no delay on multiple jumps, either. So, the problem occurs only on the very pc where the recordings are made and stored. Since the Jump controls are keyboard keys i tried disconnecting our wireless keyboard and using a USB-wired keyboard, but the same problem occurs. We even tried using an SSD to store the recordings but, again, it made no improvement.
Does anyone know how to fix this, please?

That is correct.

It's all about disk and computer CPU speed to read, decode and get going again plus "secrets."

WMC is Microsoft's own and VLC is a valiant attempt at a player that "plays them all." Microsoft did not share all that was needed to get trouble free playback in VLC. Why should they share all their secrets?

Here's the thing. As i mentioned before, our other computers can play recorded from the HTPC and jumping ahead or back multiple times is quick and reliable. There's no hang, no 10-second freeze before jumping ahead a second or even a third interval, regardless of the size of the interval.Those other computers are LESS POWERFUL than the HTPC. They have slower cpu's, slower RAM, and they are accessing the recorded shows over a network. There's no way these remote computers should have any kind of playback advantage over the computer where the recordings reside.

If you don't reveal that and more

It knows everything about the media file. It can also use another strategy to avoid delays.

Your top post plus what I know about Microosft and VLC Player is the basis of my answer. If you write another PC works, and withhold that information you mislead me.

I'll try to explain things that I see and know about but here, I only have what you tell me. That doesn't mean I'll guess what it is. But it certainly helps.

Find the VLC Player forums too. But don't leave out details like works here but not there along with exact PC details.

My first post at the top of the page includes the following sentence: "On other computers in other rooms (som wired and some on wi-fi) we can access those same recorded shows over our home network, and there's no freeze time at all when we request multiple jumps."
I'm sorry you missed that on first reading; therefore, i have highlighted some words in the sentence ....
To be clear, several other computers on our home network (using Windows home networking / Homegroup) have access to the recorded TV shows stored and "shared" on the HTPC. These other computers include a laptop with Core i5 mobile dual-core @ 2.6GHz / 8GB DDR3 RAM / GTX 460M x 2, laptop with Core i5 mobile dual-core @ 2.4GHz / 8GB DDR4 RAM / GTX 950M, PC with Core2Duo @2.66GHz / 4GB DDR2 RAM, and others. All of them can play a recorded show over the home network. All of them can use the keyboard controls to skip ahead or back multiple jumps without ant freeze or delay (well, ok, maybe one second or so when asked to skip 3 time intervals ahead). Yet, the HTPC with quad-core Core i5-4590 @ 3.3GHz / 16GB DDR3 RAM / GTX 960 will only skip ahead or back one time interval without freezing/hanging/pausing, whichever term you prefer. Requesting VLC to skip two (or more) time intervals ahead or back results in the picture freezing/hanging/pausing for approximately ten seconds before playback resumes at the requested point in time. I hope this is sufficiently clear explanation.

I work with what's in the top post. I feel you need to take this to a VLC player forum next as it's not clear what is causing it. I know the Microsoft angles.

If this is over a network, more reasons for it to pause. Copy it local and try again to see if it's the old network issues.

I get the feeling you do not want to work this issue but demand a fix or explainer. I woite video player software years ago and had all sorts of workarounds for such issues. But VLC Player goals are not to fix issues with say a pause on network playback.

Try it on a local drive.

So, it's just that computer

And it's the only one with VLC? Why? Is it Linux computer, or another Windows computer? If a Windows computer, why isn't it using the same Media player as the other Windows computers? If Linux, check repository for any upgrades specific to that computer hardware such as for the graphics card. You don't give enough info to make a determination.

Can't Make it Any Clearer

We have VLC media player on all computers. We use VLC media player on all computers. One computer is our HTPC. It has Windows 8.1 Pro with Media Center. It records TV shows using Windows Media Center. The recorded shows are stored on a dedicated HDD in the HTPC. The HDD is marketed as DVR-type drive which can record multiple programs as well as playing back up to 12 recorded programs at once over a network. On the rare occasions that we record one show while playing back a show already recorded, it's never more than one recording and one playback at the same time. For recording, we substituted a 1TB SSD which features high sustained Write capability, but the playback issue remained unchanged. The playback issue only occurs on the HTPC, and it's the most powerful computer in the house. It makes no sense to me that VLC can skip ahead (or back) multiple jumps (example: 60 sec. + 60 sec. + 60 sec.) on all those other computers, yet it cannot do so on the HTPC without freezing for 10 seconds. Go figure!

Exactly. Go figure.

There's something different but you are there so you have to figure it out.

Since it's VLC specific, you should be in VLC forums. While I've seen a number of reasons and some I noted, you seem to think this is something those that use/code such should know.

The answer is no. I don't own your cranky machine. While I would be checking the full Speccy report to see if there's a clue, I don't see it here. Another BIG CLUE is to think over the following. "It worked fine until I ________." Fill in the blank and share with the forums you ask on.

OK, that gives better info
by James Denison / December 11, 2016 5:47 PM PST

All the other computers are getting the video back through your networking, but the HTPC is getting it local. Obviously that's making a difference with the VLC. Try an experiment and put the file into one of the other computer's shared folders and then try to play it back on the HTPC through the network connection. If it works OK, then the problem is with VLC playing the file locally. Further experiment would see if the file can be played locally on the other computer you put the file by that computer's VLC program.

Let us know what happens.
