Thanks, now i understand this point.
another question : when MeGUI changes the options of x.264, why it doesn't change in the main x.264 codec configuration et vice versa ? who changes who ?

"x.264 codec configuration" icon, configures the VFW codec, while MeGUI uses the CLI.

thanks to both aku for the level mapping and sharktooth for taking the initiative and start a MeGUI profile selection

Ping->>Sharktooth
Sharktooth,
I think, it is time now someone here to say to you-THANKS for all your efforts and for the incredible MeGUI-x264 Custom video profiles. I'm simple customer. Without these profiles I was unable to achieve until now good quality. Yesterday I use some of these profiles, and they are marvelous. Thank you again, and do not forget how many people here appreciate deeply your efforts, knowledge and kindness to share. |

Sharktooth, thanks for the profiles. They are all about 10k compressed, so just one file for download instead of 4 would be simpler . I also guess you are planning to add the profiles to "x264 Full package" in your next build, so people just install it and have the profiles automatically. Or maybe even better, Doom9 could add them to the MeGUI x264 package for those who download the x264 Lite package and MeGUI separately.

Dunno if you need any input on this, but arstechnica has a decent (as far as I can tell) MeGUI guide for putting h264 on iPod. You could take their settings as guidelines for a profile. (it would probably be best to find someone with a video iPod though, just to check stuff works)
http://arstechnica.com/guides/tweaks/ipod-video.ars/6 oh and just to make sure, if checkboxes are checked but are grayed out, it does mean they aren't used right? (i.e. if you choose one of the HQ profiles and then baseline and then show command line, is --analyse all --8x8dct ok in the base profile? I thought that dct stuff enables high profile)

nice. I never thought somebody else would write a guide for a software I wrote

Hints: Suggest you sacrifice encoding-speed to maximize quality at low-bitrates by using 2 or more encoding passes based on AVC Main-Profile or High-Quality Profile, (aim for 700MB or lower in total-size for 2-hours of encoded-video with audio, ie a 1 CD rip). Note!; Xbox only have a 733Mhz Intel Pentium-III CPU and 64MB shared-memory!, and because of the limited resourses on the Xbox it helps disabling any features in XBMC that you do not use (like ex. Python-scripts, WebServer, FTP-server), also suggest you enable the hardware-overlays renderer, lower the video-cache leverls and disable all post-processing filters in XBMC. By the way, remember that Xbox/XBMC are very good at upscaling/upconverting low-resolutions to higher-resolutions (like ex 640x480 to 720x576, and 720x576 to 720p/1080i). Please DO use: - Maximum resolution of 720x576 @ 25FPS and 720x480 @ 30FPS. - ABR (Avarage Bit-Rate) for video. - Low Bit-Rate video (suggested maximum ABR; 1400kbit/sec). - Crop (remove) any black-bars on widescreen movies. - CBR (Constant Bit-Rate) for audio. - Max 448kbit/sec LC-AAC or 256kbit/sec HE-AAC audio. - I/P/B-Frames (though a maximum of 3 b-frames in a row). - P-Frames (though a maximum of 2 reference frames). - Weighted Prediction. Please DO NOT use: - Loop/Deblocking, (XBMC does support deblocking but it slows decoding). - Interlaced-output, (instead convert any interlaced-input to progressive). - Anamorphic resolutions, (instead rescale/stretch as needed during encoding). - Loop/Deblocking; (this signifantly slows decoding). - CABAC; brings down the bitrate by ~10-15% but slows decoding signifantly. The jury is out on these: - Variable Block Sizes/Macroblock Partitions; decoding not supported by XBMC yet? - 8x8 intra prediction. - Audio downmix mode "Stereo" (output channels); 5.1 is slower to decode than 2.0? (Remember to normilize or use dynamic-decomression the audio during encoding!) Links to XboxMediaCenter's forum discussions regarding ACV playback on Xbox: Nero-Digital/x264 H.264 MPEG-4 AVC codec, is the Xbox CPU powerfull enough? HOW-TO play Nero AVC (H.264) in AVI by compile MPlayer with latest FFmpeg! Nero Digital MPEG-4 AVC / H264 in .MP4 containers support (feature request) PS! XBMC currently uses FFmpeg CVS from around 4th of October 2005, does that support decoding CQM (Custom Quantization Matrix) for H.264?, if not can 'old' FFmpeg before CQM still decode MPEG4 AVC (H.264) encoded with CQM? By the way; does CQM slow down decoding?, if it does even a little then CQM should probebely be disabled for the Xbox-profile anyway? |
