1080i H264 怎麼播放?

Peter Caesar

下載了一個 1080i H264 的 .TS 檔案:
http://www.chdtv.net/viewthread.php?tid=8096&extra=page%3D1

KMP/MPC 的 Default 設定都無法播出,
勉強調用 PowerDVD 的 H264 Decoder 和 Cyverlink Demultiplexter 後
也只能看到格放的 Slide show~

請問要如何才播得順？<img src="snitz/emot/em04.gif" border=0>

Jeff Hsu

暫時好像連不上去?
請問是怎樣的檔案,找別的地方試試?

我也是掛了 PowerDVD 的 H264 decoder才可以用KMP播放~~~
不過根本是幻燈片........Orz
只有聲音正常............

這是提醒說電腦該升級了嗎!? <img src="snitz/emot/em03.gif" border=0>

Peter Caesar

我猜, 至少要支援 H264 硬體加速的顯示卡如：
ATI x1000 或 NV 7000 系列.

有人說他用 MB:

CPU:

2x NV7600gt for SLI:
http://product.pcpop.com/000026497/Index.html

這樣的話, CPU load 在 30% ~ 50% 之間, 就順了：

_________________________________

Mpeg 4 at 1080i requires some serious power and these decoders are not that well optimised.

I can play at around 20fps on a P4 3.73Ghz with an X1600 using Pdvd7

-------------------------
原因可能是
the BBC files are challenging to play back due to type of interlacing used, namely MBAFF.

CoreAVC is generally accepted to be the fastest/most efficient decoder around, but MBAFF is not yet supported. However, it was recently hinted that this support should be forthcoming in version 1.1 of the Professional Edition by around June 7th (ie just in time for the World Cup)

------------------------

OK, 應該會有3片, at right now.
Let's wait and see.

I saw this maybe helpful.


>>>>>>>>>>>>>>>>>>>>>>>>>

Currently the BBC files are playable only using PowerDVD7 (or PowerDVD7's H264 filter in another Directshow player like Zoom Player). The speed on a typical PC will be 10-15 fps. You might get 25fps on a super PC (fast dual core CPU, fast graphic) because PowerDVD7 is dual-core optimised.

VLC can also play it using the latest (after 27 May) nightly build. Not clear yet whether slower or faster than PowerDVD7. To prevent it from freezing up, in "General video preferences / Advanced options", uncheck "Drop late frames" - note this may give minor image corruption or dropped frames.

In the future (meaning 6/7 June?) we should see support in the next version of CoreAVC Pro, hopefully even a single core CPU will be fast enough. Maybe also VLC (and other libavcodec-based players) will be able to play this - currently the new code for MBAFF support in libavcodec, written only last week, is buggy.

In the meanwhile you can obviously re-encode it in non-realtime to something easier to play.

Definitely seems worth downloading even if not watchable as it is.

>>>>>>>>>>>>>>>>>>>>>>

結論是,
1. H264 硬解的顯示卡
2. H264 硬解prgoram or decoder. Powerdvd7 deluxe
3. 利用dual core CPU 目前是比較可行的方法.
Peter 你要不要考慮 upgrade? or 試試SLI?
不然就等看看新的coreavc after 6-7th June.

Peter Caesar

To upgrade my PC just for the three files? Definitely not.

我要等 Intel 下半年的 Conroe,
下半年的 HDMI vga adapter,
Vista,...........

Peter 兄
我的 NV 6600 AGP 用 powerdvd7 delux, 雖然未能打開 DXVA, CPU 100%, 但至少有 12-15 FPS 吧 ?
Just Try It !

我跑 Overaly 的話, 大概有 1x FPS;
但是跑 VMR9 就只剩 6 ~ 7 FPS~

距離檔案本身理想的 PAL 25FPS 有一大段距離, 昏倒！
看來, 我又幹了一件蠢事.

Jeff Hsu

以最開始的1:12來統計.

KKMP跑overlay 可以順, 80-90cpu loading
VMR9 約10-20 fps, 95+% cpu loading.
powerdvd 跑最好, 開cpu loading 可以看到兩個cpu 圖形,明顯不同,
也就是powerdvd 確實分工給兩個cpu.loading 約在60-70, 動態大時約在85以下.

以上loading 以按crt+del+alt 的工作管理員的效能為準,其他的kmp 或是imon 上的cpu loading 都不準,
那都只有顯現40-60 %,但是卻噸的不得了.

請問KMP 如何在overlay 下看準確的fps? TAB 的fps 不準確.

Peter Caesar

我說的 Overlay 1x FPS 只是比 VMR9 6~7 FPS 順暢一點的估計值.
總之, 距離檔案本身要求的 25 FPS 還很遠∼

更氣的是, 我三天內就莫名其妙的下完了三集 (約 26GB), 正自暗爽,
....@#%(@&^_)(... 竟然沒一集可以耐住性子看完！

Haali的新版分離器，CoreAVC 1.1.0.5帶的，可以用來分離這種H.264的TS流
也能調用CoreAVC來解H.264，但是.....還是很卡，怪了，難道是用Highprofile壓的(wow不就比apple的還高級)
PD7的解碼器不用說...更卡(我的VGA不支援硬解H.264)
