Playing recorded files on H1 from P1, especially HD channels
Hi
I have recently added an H1 to a second room. I have a P1 in the family room where I record tv shows. I have 4 questions related to watching the recorded shows on the H1,that I have not been able to find existing answers for in the forum.
1. Can't delete a file on the P1 from the H1. H1 screen gives you the option, but....
2. Is there anyway to display the file list in "when recorded" order as opposed to alphabetical?
3. The resume playback function doesn't work. Should it?
4. When trying to playback a Hi Def channel I get no audio and the video looks slightly jittery. This is a big one for me
Other info: My LAN is hardwired. Have no problem playing .mkv files from my PC on the H1. Both using 280 firmware.
Any insights greatly appreciated.
Michael

Re: Playing recorded files on H1 from P1, especially HD chan
... the Delete menu item is greyed out (and several others). That's correct. File deletion isn't supported over a WizPnP connection.michaelp2005 wrote:Hi

Yes. POPUP>Sorting Options. But your current selection has to be a recording, not a folder (that last bit's a bug).michaelp2005 wrote: 2. Is there anyway to display the file list in "when recorded" order as opposed to alphabetical?
It appears to make entries in the resume marker file, but as you say, resume isn't offered when a WizPnP recording (or media file) is restarted. I've posted on the DP-S1/P1/P2 forum to ask whether this problem affects all WizPnP clients, or whether it's specific to the H1.michaelp2005 wrote: 3. The resume playback function doesn't work.

Unfortunately, HD streaming using WizPnP only works reliably when the server is doing nothing but serving the streamed file. This can be achieved by selecting the File Player or Setup screen on the server. This may be an inherent limitation.michaelp2005 wrote: 4.

Re: Playing recorded files on H1 from P1, especially HD chan
Many thanks for the info. I will try your suggestion re playing the HD file. I'm thinking a potential work around is to copy the file to my PC and then view.
I've also just noticed that FF and Rewind don't work. Is that another limitation or known bug? Skipping works just fine.
It's good to know what is and isn't a bug
Thanks
Michael

Use the LEFT and RIGHT arrow buttons to move between the columns of the menu, in exactly the same way as on other Beyonwiz models.michaelp2005 wrote:...

Re: Playing recorded files on H1 from P1, especially HD chan
Is this something that can be addressed with future firmware? My P2 does this and I'm surprised since the tuners are HD so one would think the pvr would have enough processing power to handle streaming HD content to the H1 while watching live HD on the P2.prl wrote:

Re: Playing recorded files on H1 from P1, especially HD chan
The problem is apparently due to the internal bus bandwidth on the main chip. To guarantee that the functions of the server itself are not affected by streaming operations, the Beyonwiz engineers have deliberately limited the networking throughput. I have posted a table of how activity on the Beyonwiz affects the speed at which it can deliver data to the network.Trial_Master wrote:Is this something that can be addressed with future firmware?

When I said "inherent limitation" I meant just that.

Re: Playing recorded files on H1 from P1, especially HD chan
Sure, just needed to be 100%. Dam'n. We use the BW P2 - H1 streaming all the time and this has just become an issue since getting a HD TV last week.prl wrote:

I guess I will have to go back to recording SD content as a workaround. Seems a funny limitation as I mentioned with the unit being a HD PVR.

If you look at the table I posted the link for, you should be able to watch HD on the P2 while streaming HD to the H1 if timeshifting is off on the P2. You may be able to still stream reliably if timeshifting is enabled on the P2, but you stay watching live (yes, I know that sounds pointless, but if you can, then at least you don't have to remember to disable timeshifting before streaming). You may also be able to stream HD while watching a HD recording on the P2 (I don't have measurements for that, but it has a similar load on the server as timeshifting enabled, but watching live). If a recording kicks in while you're watching live HD but with timeshifting enabled, the streaming is almost certainly going to suffer.
I'm not trying to say that this is satisfactory performance, just indicating the likely consequences of what I measured.
If you're willing to experiment a bit, I'd really appreciate any feedback about whether the table of network throughput really does serve as a good predictor of whether a Beyonwiz can successfully serve HD recordings. The second table in the post should give an indication of what absolute minimum network throughput is needed to serve recordings from those channels. Please post any results you have in that topic. Anyone else who has a streaming setup and who's willing to try this out, please post any results, too.
The table I've posted makes it easier to compare streaming (and WizFX copy) performance from version to version, but unfortunately, it's not clear whether it reliably answers the question "will this particular load on my Beyonwiz allow me to stream this recording?"

Thanks Peter. I'll have another go and report back on the outcomes.
My situation was a little different to those described. I was playing a HD mkv on P2 from my PC and the H1 was streaming a SD recording from P2. My playback and the H1's playback were both affected with staggered pictures and continued loss of audio.
The second situation was watching a HD broadcast on P2 with TS active and H1 streaming a HD recording. P2 was fine but H1 was affected with staggered pictures and continued loss of audio.

I'm not all that surprised by the first result. Do you happen to know what the bitrate, frame rate and resolution of the MKV file is?Trial_Master wrote:Thanks Peter. I'll have another go and report back on the outcomes.

The second one is disappointing. My tests show the Beyonwiz with a throughput (TS enabled but not being used) of about 18Mib/s and the highest bitrate HD broadcasts (in Canberra) being about 14Mib/s, though that's not much headroom for random variations in the server or network load.

As far as I know, not when it's not being used. There is evidence that WizTV has a memory leak that can affect the performance of the Beyonwiz if WizTV has been used a lot since the last restart.Trial_Master wrote:Does WizTv impact on procesor? I wasn't using it at the times but I have active accounts on both P2 and H1.

A HD broadcast was being watched live, TS was enabled (I've never disabled it). Sorry about the confusion.

A tiny bit. MKV container contents have to be parsed entirely in software. TS streams can be pushed through the hardware to extract the individual streams. On the other hand, MKV is simpler to extract data from.
Empirical evidence suggests that TS pushed through hardware is (at this point in time) more efficient, however since Beyonwiz have full control over the MKV code, it may be possible to optimise it such that it performs better.

I was thinking that the particular case (streaming MKV HD from PC to P2, streaming SD from P2 to H1) may have simply run into network limitations, rether than chip bus bandwidth limitations. I guess both are possible.peteru wrote:Decoding of AVC/H.264 content (most MKVs) is very bandwidth intensive - a lot more than MPEG-2 (broadcast) decoding. MKV playback is likely to run the processor out of bandwidth pretty quickly.
One useful test might be to upload the MKV to the P2 HDD, and see if it can be played on the P2 while the P2 streams SD to the H1.

Thanks. It looks as though the problem is the combined network traffic for the MKV and the SD recording. Can you find out what the bit rate of the MKV is? Or alternatively, how big is it, and what's its play time?Trial_Master wrote:We ended up doing that and everything worked fine.prl wrote:One useful test might be to upload the MKV to the P2 HDD, and see if it can be played on the P2 while the P2 streams SD to the H1.

Trial_master had the problem when simultaneously streaming the MKV from a PC to his P2 and streaming an SD recording from the P2 to his H1. He later said that if he copied the MKV to the P2, he could play the MKV and stream the SD without a problem.peteru wrote:That MKV plays fine for me, directly from one of my Linux file servers, which is only a P3 @ 600MHz and serves several other machines at the same time. Playing back on a P1 connected using Cat5e cable to GigE switch.
The problem here doesn't seem simply to be the playback of the MKV.

Hi all,
A little off the topic but in line with the subject heading. Last night I was playing a movie in the bedroom on the H1 (as I now have headphones to please the wife). Anyway, every 5 - 10 minutes the movie just stopped playing and went back to the file menu. The movie I was streaming was coming from the P1 which was recorded from live TV.
After a few restarts of the movie and finding the spot I was up to I rebooted the H1 and placed the P1 into File Player menu in case time shifting or something was causing an issue. No Joy, movie kept dropping out back to the player menu.

Note that it's a WizPnP server problem, and if you go back to an earlier version, you need to do it on the P1 in your setup, not the H1, to fix this problem.pauliking wrote:Thanks for the response guys.

Streaming HD between BWs is a chancy business anyway, even without the server bug.
