r2334 View full changelog OpenCL support improvement/refactoring Autoload the OpenCL library so that it's not required to run an openCL-enabled build of x264. Update X264_BUILD, which should have been changed with the first patch. r2333 x86: shave a few instructions off AVX deblock r2332 x86: AVX2 dequant_4x4_dc r2331 x86: AVX2 high bit-depth dequant r2330 x86-64: 64-bit variant of AVX2 hpel_filter ~5% faster than 32-bit. r2329 x86: AVX2 high bit-depth denoise_dct 28->15 cycles Also reorder instructions to use fewer registers, 3 cycles faster on Ivy Bridge with 64-bit Windows. r2328 x86: AVX2 high bit-depth quant quant_4x4: 13->6 cycles quant_4x4_dc: 14->8 cycles quant_8x8: 47->24 cycles quant_4x4x4: 48->25 cycles r2327 x86: AVX2 add16x16_idct_dc 27 -> 19 cycles r2326 x86: faster AVX2 quant_4x4x4 10->9 cycles r2325 x86: AVX2 intra_sad_x3_8x8c 30->22 cycles r2324 x86: AVX2 high bit-depth intra_sad_x3_8x8 43->24 cycles r2323 x86: AVX2 deblock strength 30->18 cycles r2322 x86: Faster high bit-depth intra_sad_x3_4x4 20->16 cycles on Ivy Bridge r2321 x86: faster SSSE3 hpel ~7% faster using the pmulhrsw trick from mc_chroma. r2320 x86-64: faster SSSE3 trellis ~2% faster trellis. r2319 x86: 32-byte align the stack if possible Avoids the need for manual 32 byte array alignment on compilers that support -mpreferred-stack-boundary. r2318 x86inc: Utilize the shadow space on 64-bit Windows Store XMM6 and XMM7 in the shadow space in functions that clobbers them. This way we don't have to adjust the stack pointer as often, reducing the number of instructions as well as code size. r2317 x86: Don't use explicitly aligned versions of SAD on AVX CPUs On modern CPUs movdqu isn't slower than movdqa when used on aligned data and using the same code in both cases saves cache. This was already done for the high bit-depth AVX2 implementation but the aligned version still exists as dead code so remove that. r2316 x86: Add missing initializations for high bit-depth sad_aligned r2315 x86: add Jaguar CPU detection r2314 x86inc: Remove .rodata kludges The Mach-O bug was fixed in yasm 0.8.0 and we don't support versions that old. a.out was superseded by ELF on sane systems a few decades ago. r2313 checkasm: Use 64-bit cycle counters Prevents overflows that can occur in some cases. r2312 checkasm: Fix stack alignment bug r2311 Fix invalid memcpy in sliced-threads Likely didn't actually break in practice, but memcpy with src==dst is incorrect.

Brilliant software. I use this commandline tool as part of a conversion sequence to turn TV captures into smaller .mp4s for later playback on a "WDTV Live" box. The X264 commandline can be daunting to figure out initially (examples abound though, just search) but once you have a useful commandline then Bob's your Uncle. eg "my" commandline creates h264 video which is proven fully compatible with the WDTV Live in terms of the "video technical compliance stuff". Happy days. X264, when combined with FFMPEG to convert audio and with MP4box to mux the video/audio into an .mp4, provides you with capability to create your own (repeatable) custom tailored encodes. Fantastic.

Extreme compression might be a very good feature for Sharing in-contra to my previous comment. Still figuring-out quality settings for personal back-up. Other ripping tools like Xvid4PSP, StaxRip, RipBot264, FairUse Wizard, MEGUI must be updated to this version accordingly.

v r1703 better compression, but, video loses overall sharpness. it's disappointing. Target Video Bit rate : 1 500 Kbps Actual Video Bit rate : 817 Kpbs (Too Low than target results-in poor Quality) Hope for better improvement in next release.

Simply the best implementation of H.264 spec. It is a CLI tool so some patience is required to learn it, otherwise use some great GUI's like Ripbot, StaxRip, or MeGUI.

The BEST, and my most favorite video encoder. Thanks for continuous updates. Note:- ====== x264 vfw requires same trends for updates too!

Simply The Best H264 encoder available, no doubt. Thanks to authors for keeping FREE, and running a good show of updates.

By far the best H.264 encoder I've ever experienced. It even dwarfed all these commercial products and it's getting better!

Unless you device does not support h264 part 10 (AVC) then there is NO REASON why you should not be using x264, even if you are not a console God , there is plenty of GUI's that harness the power of this codec implmentation.

I have been an AVI with XviD and MP3 die hard fan for a LONG time! I just recently graduated to using MKV files and building my own chapters. THEN, I discovered that I can encode H264/X264 files and *directly* mux the AC3 audio from a DVD rip into an MKV. What I did NOT expect was the quality of video as such low bit rates. I very extensively use my Western Digital WD TV to play the videos I make on. When using XivD to encode 720 videos (1280X720), I *must* run at least 5000kbs to have a decent picture. With H264 (or better yet, x264.exe) the video quality is superior, at only 2500kbs!!! Now I wish my Creative Zen would support 264, because it is leaps and bounds better than WMV9!! I love this CLI tool, thanks so much to the author(s)!!! I hope to have a GUI built soon, and have plans on making a GUI tool kit for MKVs! Thanks!

With this codec,you have DVD-like picture quality on VCD bitrates! IMO, the future is here, in this codec! I use it with super encoder to batch convert dvb mpeg2 files of various framesizes. The speed is 1/4 realtime on my core 2 duo 6600. The vfm version is faster (about 2/5 realtime). You can use it with virtualdub. An excellent choice for those who like cutting edge solutions, or something with great future in front of it!

X264 is the best codec I ever used. Thanks to DeathToSheep for the unofficial VFW version I can stay using it with virtualdub. I capture with Mainconcept PVR in MPEG2 (quality 32) and convert with VirtualdubMPG to AVI files (X264 -single pass bitrate 800) With this combination of videotools I can put 13 episodes (50minutes/episode) of my favorite "Aspe murders" soap on 1 DVD and the quality is much,much better than VHS.

After being skeptical about AVC H.264 I finally broke down and decided to try it for some iPod movies. The source files were MPEG-1 @ 1856kbps ripped from some high bitrate xVCD's I did years ago, I tried doing these with 3ivX and DivX 6.2.5 and wasn't pleased with the results especially on HDTV, I tried x264 using MeGUI and I am blown away by the 2-pass quality @ 700kbps. Even at a low resolution of 352x144 these movies look good (not great)on a 42" HDTV and the file sizes are quite small. MeGUI is a very powerful program but not exactly for noobs, When the ability for 640x480 iPod resolutions becomes possible this codec will be unstoppable!!

What's xvid?? what's divx?? what's wmv?? No way X264 the best codec ever. High quality in low bitrate. This awesome codec use for me for months.No rival. Cauptain

Better quality than XVID and a smaller file size. Use the latest FFDshow from Celtic_Druid for playback. Be aware that playback is CPU intensive - Not designed for < 2.0Ghz machines (yet).

works now correctly in sony vegas - testing quality against other H264, but so far - this is a winner ..
