1080i streaming is choppy over DMA2100 via 802.11n

lol, definitely a firmware issue then.

Or a decoder chip problem.

mpeg 2 and even 4 has been around forever, kindda hard to screw that one up.

I was thinking more along the lines of a physical problem with it.

so have them ship you another, unless you think the thing is just designed wrongly?

Their testing would show that I think.

its not good enough that I reencoded the file as AVI which plays fine, now they want me to reencode it as WMV and try that. Oh well, guess I have something to do tonight.

wtf, you have to do the encoding?

 

[Ryland]

Well I don't seem to have anything that will reencode an mpeg2 as a wmv at 1920x1080, crap. They are going to have to be satisfied with AVI.

 

[Ryland]

Linksys is going to RMA my DMA2100. They still think it won't play any MPEG's even though I keep telling the idgit on the phone that it will only NOT play 1920x1080 mpeg's. Oh well.

 

[Ryland]

The RMA unit is showing the same issues as my original unit. There must be something more going on or a limitation on their mpeg chip.

 

[sdifox]

oh well, you are screwed then. I still don't understand their argument... can you post the info on the mpeg2 file you are trying to post? like the bitrate for audio and for video. I wonder if it is the stream size.

 

[Ryland]

Yeah, I can do that tonight via Videoredo. I also have a 32 second clip that causes the problems on my extender.

 

[Ryland]

Video Stream:
Dimensions: 1920x1080
Stream ID xE0
Aspect ratio 16:9
Frame Rate 29.97
Bit Rate 38.711 Mbps
VBV_Buffer 1194KB
Chroma 4:2:0

Audio info is:
Stream ID: AC3: 0 x80
Channels: 5.1
Bit Rate: 384Kbps
Sample Rate: 48000Hz

 

[sdifox]

is there a througput test you can do on the media extender? 39Mbps is substantial, but well within 802.11N's 74Mbps typical throughput.

 

[Ryland]

There is a connection test but it only shows bars. My wireless connection shows all bars green with the last one flickering. The last 4 bars are within the HDTV region.

 

[sdifox]

got a laptop with wireless nic? try to map the drive then play from the laptop. At this point I am just trying to figure out if there is anything that can help, but it doesn't look good.

 

[Ryland]

That was actually one of the original tests I described at the beginning of this thread. When I did that I was able to stream the video without any issues.

I thought you streamed through a hardwire and not wirelss?

 

[Ryland]

I have done both actually to the media extender but as a test I put my laptop at double the distance and double the walls between from the router and was able to stream the same file to the laptop without any issues just to make sure I didn't have any throughput issues.

 

[sdifox]

I guess you are sorry out of luck.

 

[Ryland]

Yeha. I just got off the phone with the linksys level 2 tech support person and he thinks that the recordings are at too high of a bitrate and the mpeg processer is choking but he is going to verify it with the file I sent him.

you mean like it's within the mpeg spec but not withing the device's spec 🙂

 

[Ryland]

Yeah exactly. I went looking for the specs on the device and according to Newegg it should handle what I am sending at it but I can't find anything concrete on Linksys' site which figures.

 

[Ryland]

Well the Linksys tech was able to play through my clip 6 times with only minor artifacting so it sounds like my clips are at the border of what the decoder can handle.

data rate for xvid avi is far less than mpeg2.
and well converting will soften the video further.
