Issues with FF and Seeking on HD .ts files specifically

[jt25741]

With mvpmcx2 It seems most files in my library work fine with both FF and Seek (navigation button to time stamp). Yet with HD .ts files, I cannot seem to get more than few second jump...and this requires a repeated pushing of a button...and not faster or significantly faster than just allowing it to play due to the hesitation each time button is pressed. Time seek with these files does not work at all. So far it seems all the .ts HD files captured via my tuner to NPVR suffer from this through mvpmcx2. Now if I go to my normal NMT interface, these same files (if they are streamable at all), are all able to seek just fine (very important), and FF( slightly less important since it is really just fast play). But without any effective way to move past commercials on these .TS files in mvpmc(again other types work fine), usefulness is greatly diminished. Commercials are long and boring, needless to say

Thanks for any help........is it a config problem? If so, which logs should can I zip up?

You are skipping with the keys that sub posted about right? mvpmcx2 does not use the arrow keys, or FF like the NMT software RW/FF are just short skips, Prev/Next are longer skips

Default value configured in config.xml

Code:

<SkipForwardSeconds>60</SkipForwardSeconds>
    <SkipBackSeconds>30</SkipBackSeconds>
    <SkipFFSeconds>10</SkipFFSeconds>
    <SkipRWSeconds>10</SkipRWSeconds>

There is no time seek, there is relative time in minutes from the current location then hit Prev or Next for the time. Eventually you might consider comskip.

Always post all the logs.

Thanks martin...much appreciated...I need to program the next and prev buttons in my harmony(somehow I have got along without them till now)....the core of my issue here. In mvpmcx2, time seeking using the navigation arrows seems to work perfectly for xvid, mkv files....so that is fantastic. Only not these .ts files (but these do work on NMT native).

Is there a technical reason why seeking doesn't work with only these .ts files, or is this an implementation decision of yours? Curious here, as to why.

BTW....Your streaming decoder seems so much better than native Syabas...perhaps they should be licensing it from you.

I will start looking at comskip...to understand what I need to do there. If any others are reading this post, I appreciate any tips and comments regarding integrating comskip (gotchas and advice...etc.)

Yes the mvpmcx2 client is totally different then NMT software player (which is still used for everything but mpg/ts files) and while I wrote the client with help from sub on the server side, the decision on how the NPVR backend works is sub's. I think most GBPVR and NPVR users do prefer this method and it is pretty natural once you get to it.

Can you clarify for me - do you mean (for example) pressing the skip button, which would normally seek forward one minute, doesnt work? It should do.

Hello Sub,

Thanks, I will clarify. The skip button does what you say above...this works fine. My error in not having this button programmed on my harmony.

The question about seeking, specifically, is using the right navigation button (in the middle of the PCH romote) -- which seeks through the file very quickly displaying the timestamp while doing so. You can release it at the specific time you want to view from. This works with .ts files in NMT/native -- while not in mvpmcx2 on the same file. I was curious as to why this cannot be made to work...it is a useful feature for finding a specific spot to start from.

Other than sub's preference for NPVR, the arrow keys are needed for navigation in the OSD EPG that allows you to schedule recordings while watching something and also for navigating the mini guide in LiveTV

Ok, just a terminology thing then. Seeking & Skipping in my mind both refer to dynamically jumping to another part of the file. What you're referring to is often termed 'fast forward', 'multiple speed playback' or 'trick play'.

I'm unable to do it on the PC, due to complications with core Window's directshow components not being able to do rewind or greater than 2x speed (requiring custom demux filters etc to fix), so the UI and navigation is designed around what is possible on the PC. The same behavior exist on the NMT because it is more convenient to have it behaving the same everywhere.

The reason you're not seeing it with other file types is because NPVR takes no part in the playback of these other file types.

Sorry for the confusion, and thanks for the technical explanation..... this helps my understanding.... Soon, I will be able to help others with my growing understanding of all things NPVR

I've also been thinking of putting FF/RW back into mvpmcx2 as a option over short skip, I just haven't got around to it yet. This isn't the same as arrow key navigation which I would fight against even if sub wanted to try it because of the issues we have discussed related to no-autorepeat and screen lagging, it is about 300ms just to draw on OSD update over video.

I should also add that skipping ts files with the native player is highly variable, sometimes it can even in the wrong direction, using sub's style including Timing.Info you can usually skip with 1 second or less accuracy.
