Q1: When will the new trustworthy version be released?
Daily. But for a while I haven’t compiled x264 for win32. So I link to external versions (usually x264.nl)

Q2: What does mean in summer?
A: This means that daily builds in the summer are just longer “daily” builds for obvious reasons

Q3: What are your builds?
A: Officially no, my name is not the “official” builder, but the Beyond links are for builds.

Q4: What are the general differences in “standard SVN” between versions and path versions?
A: The patched versions usually contain the latest updates (beta or experimental – even from third parties, and sometimes me), which are usually developed in SVN in the future.

Q5: What does MMX suffix mean? Do your builds only work with MMX?
A: The suffix MMX (no longer used in the filename) means that you really need an MMX processor.for my job, but if SSE / SSE2 is present they can be used as well.

Q6: What compilers / software do you use to create MingGW assemblies?
R: + GCC + YASM

Q7: I heard that this Intel Compiler (ICL) produces faster binaries than GCC. Why don’t you use it for your assemblies?
A: ICL would be faster only if DSP routines (websites that consume CPU cycles) were not written in assembly language. Compiling with x264-ICL will not produce significantly faster x264 binaries. ICL for Windows is also paid software.

Q8: I tried to encode a movie using the main x264CLI, but the output file may not play (or the CLI crashed during encoding). What the heck?!?!?
A: You’ve probably tried to encode 23,976 or other non-FPS sources with an older version of x264. Make sure you get an updated version as well, if you still have problems, just use RAW and mp4box to create a nice working MP4 file, or check this link for a workaround.

q9: Does the latest GeexBox / XBMC read my x264 encoded files?
A: Yes, but still make sure you have the latest alternative. Since version 0.98.6, it only supports basic h.264 profile decoding. This means that 8x8dct and non-standard matrices are not supported in your life. The new GeexBox version can be updated to the latest libavcodec and can support high profiles.

Q10: Can I play x264 encoded files when changing Xbox?
A: Yes, but it depends on how much you’ve changed your Xbox Live. The standard Xbox is equipped with an absolute 733MHz processor that cannot decode all x264 (or AVC in general) features. If you don’t have an Xbox processor mod (the processor will be replaced by a 1.4GHz processor), there are a few instructions you should follow when encoding new files using x264 or other AVC encoders.
Please see this thread for more information.

Q11: What’s the difference between VFW and VFW cli?
a: This is probably a video for Windows, an older technology written by Microsoft (copying some things from(From Quicktime), full of quirks and unable to support modern codecs. x264VFW is a bad way to make x264 work (more or less) with VFW, hence software like Virtualdub and its modifications. is NOT recommended for x264VFW. x264 VFW should no longer be officially supported.
CLI is a generic term for command line interface. A classic console command (command line) that is definitely versatile and has no limitations like VFW.

Q12: What is AVC2AVI?
A: AVC2AVI a is an element for placing raw AVC data streams in AVI container type. It is helpful to improve your encodings with either virtualdub (mod) like TV editors that don’t support MP4 or other formats. AVI is usually associated with VFW. Usage with h.264 / AVC streams in AVI is not recommended.

Q13: x264 is usually very slow, why?
A: The x264 power supply has many optimizations, but it is a very complex codec (more than xvid with any other ASP Mpeg4 codec), which is perfectly normal behavior. More quality = less speed … but blahWith this optimization, x264 might even want to be super fast. If you like faster speeds, keep the bells and whistles off and stick to the settings to keep it normal. Where

Q14: Can I develop older versions of your assemblies?
A: I which keeps an archive of my old sets, so you can’t get them, unless, of course, someone is mirroring them somewhere. However, anyone can get a revision of the old compiled Celtic Druids or Bobor. Links to the pages you see are given in the main post.

Q15: The included MeGUI does not work or does not fold. What can I do ?
A: MeGUI is almost never included in my builds. Uninstall x264, download and install the latest MeGUI from http://www.sf.net/projects/megui. A real x264 assembly is generated automatically by automatic updates.

Q16: Sometimes the current revision of svn / git is newer than the graphics linked in this thread. Isn’t everything built for you?
A: Sometimes changes to new revision types do not affect the Win32 versions and / or the final binaries that will be in each of them. NSTherefore, it is no longer necessary to compile the new version of the code, since the binaries are stored in the same way as the old single. Sometimes it happens that I did not find free time to compile the current assemblies …

Q17: Can a different aspect ratio be set in x264 and what is an AR (SAR) pattern?
A: Yes, you have set the sampling aspect ratio (SAR) in the codec parameters. Same as Pixel Aspect Ratio (PAR) and inferred from Screen Aspect Ratio (DAR).
To calculate the SAR value from the DAR, you can use the following formula:
SAR (or PAR) = DAR * height / width.

Q18: Are H.264 streams certified for x264 BluRay?
The answer is yes. The x264 has recently been updated to create streams that can be used on BluRay players. A good guide on BluRay encoding with x264 can be found at: http://sites.google.com/site/x264bluray/home

Q19: Can I use VirtualDub or any other VFW based editor to encode from x264?
A: Yes, with VFW x264 promotion, but VFW is so deprecated or limited that x264VFW is no longer supported by x264 developers, and since VFW also supports AVI, it can’t handle help correctly to handle h.264 functions without issue. This hack may affect compatibility, playback and / or editing.

Q20: If VFW cannot handle h.264 properly, is there application editing software available instead of VirtualDub or VFW based editors?
A: There are currently a number of programs that can do this. One of them is also Avidemux (a free and complete editor that is similar to Vdub but not based on VFW), and there are also mp4box and mp4creator-like tools (and corresponding GUIs) that use h. 264 stream. MKVToolnix performs normal functions for MKV files.

Q21: Is x264 (generic h.264) compatible with DivX Certified Discrete Players?
On. h.264 is a completely different codec, but the codec cannot be read offline unless otherwise noted.

Q22: Are there any other understandable OpenSource H.264 encoders besides x264?
A: Yes and no. There are other h.264 OSS encoders out there, but their development has been interrupted or too incomplete. However, the Xvid developers are working on Xvid AVC but have not released any code yet.

Q23: Do you have x264 version 1.0?
A: No, because x264 is usually in constant development. However, the unpatched versions can be considered more stable than the patched ones.

Q24: Does the x264 multiprocessor support software or multi-core processors?
A: Yes, check using the –strings option.

Q25: Who is the best / best …
Stop! There is no “best” according to the rules of the place. When you’re looking for these “best” x264 options, most of these x264 GUIs come with a range of presets to suit just about any of your needs. If you are looking for our own “best” h.264 encoder, I recommend investing in the forum search function and looking for comparisons. However, x264 is really upbeat and can hardly be overtaken by desktop encoders.

Q26: Can I use x264 for special purposes?
A: Yes, but you need to contact MPEG-LA and And Via to obtain a commercial license to use the h.264 encoder, as h.264 (also known as AVC or MPEG-4v10) is often patented.

Q28: Where can I find more general statistics on h.264 and related standards?
A: Here: http://forum.doom9.org/showthread.php?t=96059

Q29: What happened to your assemblies and the main reasons why they stopped updating?
A: I actually switched to Linux. Maybe my versions will come back in the future, but the x264.nl versions I pointed to in the first post are almost as good as mine.
