Ok I have a bug report:
Using MPC 6.4.8.5 (and older versions) and disabling the inbuilt "MPEG PS/TS/PVA" source filter to try another TS filter such as HDTVPUmp http://www.dvbportal.de/projects/hdtvpump/ or TSFileSource http://nate.dynalias.net/TSFileSource/TSFileSource.html. When trying to play a TS it errors out with the generic "Cannot render the file" error. |

AacPlus v2 problem exists in official 6484 and 6485, and does not exist in Celtic_Druid's 20050813, so maybe just updating libfaad would fix the problem.
However, some people (including Dave "Novalis" Turner from FSF) say that newer faad is GPL-incompatible. http://www.hydrogenaudio.org/forums/...dpost&p=314491 This is exactly what I don't really like about MPEG-4. European people might think MPEG-4 is a set of open standards and so automatically related open-souce software can exist, but that's not true, sadly, especially in the area where software patents are allowed, like in Japan and in US. MPEG-4 itself is nice, I like it and use it often too, but the license can be tricky. |

Liisachan: the incompatibilities with the GPL are not related to software patents. Nero broke GPL compatibility by requiring a copyright attribution in the software itself, while the GPL allows to put such attributions externally from the software (e.g. in a readme file).

Ah, okay, well, actually, I knew that, and what I did wrong was, I wrote things that are not directly related here. (We do sometimes experience patent-related limitation about MPEG-4, but that would be unrelated here....)
Personally I wouldn't mind seeing that credit in the about box or somewhere (in CD version it is in a floating tooltip). But I guess that's not the problem. PS. Is there any possibility that Ahead will change that part? Or did they do that on purpose? At this rate open-source devs might end up in thinking "then we won't use v2, just use real's decoder" and I don't think that is what Ahead wants...

I think jstembridge and Otto42 gave a good reason why it is not compatible with GPL, and nero acknowledged it, but didn't fix it.
I'm not sure what to make of the comments of Dave "Novalis" Turner (FSF engineer). He says it's a restriction, because it is not required by section 1 (that's only about the source code not about the program itself), and by section 2c (it isn't interactive[*]). Ok, so it's not required (contrary to what nero claims), and thus a restriction. Restrictions are not allowed (see point 6 of the GPL). So, there are two reasons why it is incompatible with the GPL. [*] A library isn't interactive right? Last edited by Wilbert; 31st October 2005 at 13:46. |

also FYI: if desktop is set let's say 1024*768, it doesn't mean that MPC renders it at same resolution.
IIRC, the reason why MPC subs rendering is slower is cause MPC uses supersampling, aka renders at higher that target resolution and then scales back to target one. So disabling buffer ahead makes things quite slow. And of course you need to do that in order to see karaoke :P |

noone of these three breaks the standard with their mp4 files, except maybe apple by using own extensions

Just a small side note, I think some of the sloppily written newer games are dumping the dynamic D3DX DLLs into system32, though IIRC, an application will go for the DLL in its current path first anyways. This new stuff is a royal pain in the ass...perhaps at least a static link option will appear with DirectX 10.
To elaborate on the games part, a lot of Civ4 problems were solved easily by installing the dx9 redist that came off the DVD, and of course, was _27.dll. But I also installed Shattered Union at the same time, and that installer happily dropped that file into my system32. I mentioned to Elias that hopefully apps will only love their version of the DLL, and not any others, for that method _seems_ sane, but when do companies and developers do sane things? :P

Am I the only one who is experiencing skippy audio playback for AAC in mp4 (Nero Digital LC-AAC VBR, demuxed and reimported to mp4 with MP4Box) with MPC's internal AAC decoder? It's not as smooth as when played in Winamp... But it's working pretty good most of the time, just every now and then the audio playback is like jumping. This is mp4 AAC only, no video.

But it doesn't come from resolution. I can play 1280x720 video on 800x600 screen resolution on AthlonXP2200+ and about 2-3 frames per second. If I play the same video using vsfilter I had the full 30 frames per second and 85% CPU load. I don't think MPC internal subtitle renderer must eat more CPU power than both video and audio decoders together. |

If you play it on 800*600, make sure you have only 800*600 enabled. Another thing is, as i said previously, that mpc actually might render at MUCH higher resolution than that. E.g. you allowed to use only 800*600, and the text itself is printed at let's say 1280*1024 resolution and then scaled down to 800*600 and displayed. That's why mpc internal subs are much better than vsfilter in terms of quality. Also, please take a look at subs file. check which internal resolution is allowed there. (if it's an .ass file, check PlayResX/PlayResY keys). iirc VSFilter will render the subs in this particular resolution only. But mpc might use much more. So simplistic solution would be to greatly lower allowed rezo for subs in mpc. |

dunno if this is true for ps too, but i guess so so the demuxer strictly speaking is not forced to care about he-aac Quote:
whats incompliant is the psp player which requires the proprieatary stuff, but again this doesnt make the files themselves incompliant Quote:
also the mp4 standard allows the placement of private streams in mp4, which nero uses for vobsubs so nero's mp4 files are not incompliant Quote:
