So I'm afraid libavcodec does cause the problem. |

This is a bug in DirectShowSource, which is a part of avisynth. ffdshow will never add/drop frames. Some demuxer or decoder may not report correct fps or video length before playing the video. This has no impact on TRUE dshow based application (e.g. a media player). You can change anything during playback including fps, duration, aspect ration and even resolution. However avisynth requires fixed fps, resolution, color space and clip duration reported before playing the video. DSS has to add/drop frames to match the fps and truncate or append dummy frames to match the duration.

ffdshow actually does have an option to drop frames. See options -> decoder options.

Finally I can post and report this problem.
Everything seems to work fine on MPC Homecinema, but with DiAVC I get a delay on subtitles of about 375ms. It's especially noticeable on some anime where there are signs on screen whose translation/sub appear before the actual sign shows up but I think the delay applies to all movies. No problem if the video goes through DXVA or another codec like CoreAVC. Another request: I'd appreciate if like CoreAVC we got options to set custom brightness, contrast and such. |

An option to switch between "PC Levels" and "TV Levels" would be desired, because that's nothing you can achieve by calibrating your screen.
Also more color/brightness adjustment options may be helpful to "correct" certain movies. Well, we can always insert ffdshow as a post-processing filter, but if the function was built-in, it would be much more convenient

About the "SuperResolution feature":
scharfis_brain programmed something similar in AviSynth to "nicely blow up VCDs for DVD". German doom9/Gleitz forum thread An AVC decoder of course has the advantage of already knowing motion vectors. |

DiAVC beta version 1 is released.
changes: Improved decoding performance. Add SSSE3 code. add support for delta qp>26 in cavlc mode (It is supported all along for cabac mode). I will fix the bugs related to the seeking and compatibility with other applications next. There are still some rooms for decoding performance, and I will continue to improve it.

also I find 2 bugs 1. Artifacts & sometimes green frames in some files, like this e.g. http://www.mediafire.com/?emykqthjtj4 2. Some files didnt want to start decoding in MPC-HC (1.3.1453.0) with Haali splitter (1.9.355.21) + your decoder (beta v1) (with Gabest internal splitters work good, also with Haali splitters+other h.264 decoder works too) http://www.megaupload.com/?d=BM2DPIJM So which CPU optimizations are new having now including these MMX, 3DNow!, SSE, SSE2, SSE3, SSSE3, SSE4, SSE5, AVX, CVT16, FMA3, FMA4, XOP ? nice will be what are he having now and which are you want to implant in the future, or course if it will boost up decoding... |

Only SSE2 and SSSE3 exist now in DiAVC. There will be AVX, MMX in future. If certain instruction set benefit the decoder, I will inplant it.
