a. tnx a lot, so i guess for huff it is similar? like :
vcodec=huffyuv:format=bgr32 - will that store alpha as well? --- b. another question, what version of ffdshow should one get (and where?) for proper win playback of ffv1? --- c. and another thing concerning mplayer and avs, is it possible that mplayer forces avisynth to always return only yv12? (i was trying to use '-vo md5sum' to find out that: original != ffv1 when huff = ffv1 p.s. when i compare using avisynth compare function, then: original = huff at least i cant seem to find any other explanation.... ) Last edited by smok3; 14th March 2006 at 03:52. |

a. ffmpeg's huffyuv does rgb decoding, but can only encode yv12 or yuy2.
b. ffv1 hasn't changed in a while, so any build >= 2005 february should work. I can't recommend one in particular. c. Yes, mplayer invokes ConvertToYV12() if the avs isn't already. There's no particular reason for this, just whoever is in charge of demux_avs.c never implemented other colorspaces. Last edited by akupenguin; 14th March 2006 at 11:42. |

I been tested Logarith codec (ver. 1.3.9) wich I downloaded from site (http://lags.leetcode.net).
And found that it have the same issue as 1.3.8 ver.: a bug that allowed YUY2 and YV12 video to be decoded as RGB16. So i looked at files in archive wich I downloaded more carefully (it`s name was Lagarith_139.zip): in properties of lagarith.dll i looked at version, it was 1.3.8!!! May be author made a wrong version build?... (or just uploaded a wrong file?...) stupidies marked by gray... i`m sorry.. codec work fine.. mixed out some thing...

What does lagarith do differently then huffyuv? Prediction? huffman encoding? I'm using a modified huffyuv codec with the median prediction and a simplified huffman table (one table for all three YUV planes) and it's working fine, but maybe I could 'borrow' something from lagarith to make my codec faster?

Hi. I did some very rudementary tests here on my DualCore Athlon 4200 in VDUB 1.6.17 DVCAM AVI file 4:2:2 -->
Lagarith 1.3.11 RGB24 SMP 42 Sec 328MB Lagarith 1.3.11 RGB24 NON-SMP 53 Sec 328MB Lagarith 1.3.11 YV12 SMP 37 Sec 165MB Lagarith 1.3.11 YV12 NON-SMP 38 Sec 165MB UNCOMPRESSED RGB32 36 Sec 2324MB MSU 0.6 Balanced, yv12 4:01 167MB FFV1 RGB32 VLC 2.07 301MB FFV1 RGB32 AC 2.05 297MB FFV1 YV12 VLC 1:12 181MB FFV1 YV12 AC 1:12 176MB HUFFY YV12 : 35sec 522MB Note: The files from lagarith differ in size based on using SMP or not, just a 200-300bytes, but still worrying Anyway, Lagarith in yv12 is VERY impressive imo. ITs just a 2 sec slower than huffy and 3times as efficient This gotta be the worst comparison ever but i thought id share my results teb |

Constant Quality mode 0. Think the commandline's:
Code:
x264.exe -q0 Code:
x264.exe --help

This is very-very good codec, fast and result small file, uses 2 processors too... But very often freeze if "use multithreaded" is checked. I use only YUY2 mode.
Well I see, new version 1.3.11, Good news. Problem with new codec (and last version) : codec uninstall not working (under programs add/remove) Sorry my poor english, and thanks of developer : this is very good lossless video codec. |

Great codec, did someone did a comparsion table?
I mean, with HuffYUV.
Still lots of people didn't know Lagarith, a direct comparison table can easily let them choose the codec they want. I'm capturing with Lagarith and it works great.

I found that if using Largarith with some filter combination in Vdub, the output will have a lot of vertical and horizontal color lines, up to now I can't exactly reproduce it, seems it happen under certain criteria ...
Will report here if I have any progress.

I recently used Lagarith v1.3.12 to make an intermediate file. The process went through perfectly, but when trying to make the final MPEG2 I get two consecutive error messages:
That happens when loading the plain intermediate AVI file and a simple script with a couple extra filtering steps. Any ideas as to what could be causing this? I'm using AviSynth_160906 and VDubMod v1.5.4.1b2066.

RGBA and Alpha
Hi,
I am currently trying to implement AVI support into a OpenGL game engine. I have successfully got the engine to decompress AVI frames and render them in RGB. For various reasons I really need to get the alpha channel. I cannot seem to get a reliable AVI file, with alpha and Lagarith compression. I tried VirtualDub-1.7.8 and it seems that it does not support alpha channels in its conversions. I tried the Color Depth option for 32 bit RGB (888) (dummy alpha channel) and it made my movie go all semi transparent with vertical black lines. I also tried creating an uncompressed .mov with alpha, and using the movtoavi from http://lags.leetcode.net/Codec_mac.html and the avi result was black and white gibberish. Does anyone know a reliable way of creating Lagarith compressed AVI's with the alpha channel? Cheers in advance, Lee |
