Help reproducing HD files

No, it's not true. 1 kilo is not 10^2 but is 2^10. Even if you count 8 times 1024 that's 8192 bits, not 8000. But surely, 1 kB is 8 kbit, 1 MB is 8 Mbits and 1 GB is 8 Gbits. Remember, always 1024.

@adicoto: I think we totally agree but: yes it is true! 1kB is not equal to 8000 Bit.
Or otherwise noted: 1 kB != 8000 Bit.

("!=" like "<>" like "≠" all mean "unequal")
P.S.: By the way: i.a. missing crumb, nibble, word ... etc in your lecture

[adicoto]

Yes, but someone in here (gues who ? ) didn't read the ! :oops:

[BSPeter]

:D I already thought so!

[adicoto]

But 1 MB will always be 8 Mbits.

Nobody is argueing about that!

Let alone the new kibi (Ki) and mibi (Mi) for now, I don't like them. I think bits should always be expressed in decimal manner, where 1 kBit = 1000 Bit.

For example, 28.8 kilobits per second (Kbps) is 28,800 bits per second. [1]

and media stream bitrates closely relate to telecommunications.

However when storing these bits we cannot escape use of bytes. A certain amount of bytes is required for a given stream, then the usage of 2^(n*10) nobody is arguing about applies.

Back on topic, I did have problems some month ago, playing HD files (1920x1088 @ 25) in MPEG2 format. My laptop (1.6 centrino 512 MB) did not managed to play some of those files fluently, sometimes half of the fps. But played OK 1920x1088 XviD files.

[J7N]

Well, same here. I compared regular 350 MB MPEG-4 rip (1.1 MBit/s) with a MPEG-2 music video of approx the same resolution. XviD required less computing power. I could barely play the MPEG2 with Elecard, no free decoders could do it.

I never tried to play HD movies, I'll try with those trailers :)

And if we want to be really rigorous kilobyte(s) should be written with a k (lower-case) and not with a K (upper-case) since in the SI (Syst?me International d'Unités) K stands for Kelvin (thermodynamic temperature) and k stands for kilo ( even if I always write KB, Kg, KJ, etc., instead of kB, kg, kJ :P )

Ok, I could spare you this, sorry :D

[adicoto]

Back offtopic. Sorry Tizio, I can't find any K in my post. Just k.
It was caused probably by the cold, you know, in here is like - 10 K. :)
Et ceratinement on a pas de kb et kB en francais. Parce que ils ont des octets et on ecrit ko et kO.

[J7N]

There's enough confusion already with 1024 and 1000, "k" and "K", Bit/bit/b. Please don't introduce these octets. :shock:
I wonder how French call bits...

[adicoto]

As you see. we are totally offtopic. Just a little chat :D.

By the way, did you wonder how they spell computer ? Ordinateur.

It was not referred to you

I wrote "Sorry adicoto" only because you turned discussion On-topic and I wanted to apologize to have went Off-topic again :P :lol:

[adicoto]

Most of the forums I am active do have an off-topic topic :D
Aha, I understand, and that's why I put a trap for you in my statement. There is no such thing like -15 K. 0 K is the coldest possible. :D

What do you think, should we go back on topic ?

[J7N]

Ordinateur? The one who puts things in order. I like that. :)

What do you think, should we go back on topic ?

Any time, as soon as some new info about hi-res videos arrives...

Well, do you have more tips? Now I'm downloading a TS file with approx 6mbit/s, I don't think its gonna play it Ok but Ill try. One important thing I've noted is, using Bsplayer I get the divx aplication executed in the background, unlike using VLC. Maybe that app is causing the problems I have with the others players.

How many bitrate do you think my system support for playing HD Ok?

Thanks!

I can play without problems this:

thaaaaaaaaanks again J7N!!!! whats the thing with VLC?

It doesn't do any processing of the decoded data by default. VLC uses the same free libraries as ffdshow.

If your comp is slow compared to the content you are going to play, I recommend installing ffdshow video decoder for MPEG-4 (DivX, XviD, H264) and Elecard MPEG2 Decoder for MPEG-2 (DVD) playback. Prior to that you must uninstall any DivXNetworks software. You may keep XviD codec (if you do have one) in case you want to compress something. If you decide to install ffdshow, you must enable the video and audio formats you want to decode and leave others (like Mp3) unchecked, and also disable any post-processing. ffdshow can be re-configured later using Start menu shortcuts or the property sheet of this filter.

The background application might be a harmless tray icon, but may also be doing some redundant demuxing, dunno: Check CPU usage in a task manager.

FFDShow has no drawbacks compared to latest DivX software. Even distributive size (dxn = 15 MB) and mem usage is better.

This also depends on the format, decoder used and the interface to call that decoder. MPEG-2 requires more computing power than MPEG-4 ASP (DivX, XviD) and H264 needs even more. Old DIV3 decoder was slower compared to ffdshow. Bad combination of OS, video drivers can result in very slow VirtualDub(Mod) interaction with normal VFW codecs...

Thanks for this advice; but at the moment everything works fine so I'll let the config as is, then if I've get problems with some movie or larger file I'll try this.

:arrow: I've downloaded a TS file, it plays ok with VLC, but when I select the subs it doesn't show them at the screen, do you know what could be posible causing this?
