I have upgraded to 046 and since I have had a couple of system hard lockups when hardware decoder is set to none. No locks if its set to a hardware decoder. This has only started with 046, 045 was fine with decoder set to none.
edit, please ignore this.. I think it was a system issue. Last edited by Razoola; 13th February 2012 at 19:19. |

Golden solution for dithering is Floyd-Steinberg+bit of random noise, but ordered+bit of noise will be sufficient in most cases and much faster. Both ordered and random by itself have visible side effects.

For FPS1(yuvj420p) files could you automatically apply TV-levels with VMR-9 Renderless as well as you've done for EVR. The only thing left for both renderers now is BT.709->BT.601 luma conversion and LAV can perfectly decode Fraps files in YV12 mode.
- LAGS(rgb24): No problem - LAGS(yuv420p): No problem - LAGS(YUY2 / YUV 4:2:2 / yuv422p?): Splitter fails. With MPC Avi Source + LAV Decoder the file opens but no image and stays at 0:00. Only MPC Avi Source + LAGS vfw decoder works fine. SoC_[SNOW+Vorbis].mkv: Opens but no image and stays at 0:00. With MPC Matroska Source + LAV Decoder there's no image either, but at least the Vorbis stream is playing. About FFV1, it all plays fine, but what exactly is "bgr0" for a colorspace? I'm not at all convinced atm FFV1(RGB32) is actually a lossless format. Output is completely different compared to Uncompressed, HFYU, LAGS, MLCY, and MSUD (RGB32). VP61 issue: - predator2_vp61.avi (VP61): No problem - vid.avi (VP61+MP3): Opens but no image and stays at 0:00. With MPC Avi Source + LAV Decoder there's no image either, but at least the MP3 stream is playing.

since 0.46 i have notice a odd bug with decoding. to make sure it wasn't just that 1 build so i tryed the nightly from http://roy.orz.hm/lavf-w32-nightlies...213-b92b5da.7z which still gives me the same problem, it seems it picky on how the .ts has been saved i have uploaded a sample so you can see what the problem could be. video sample
0.46 slow 0.45 fast (normal it will be over 2x as fast on a bigger sample) |

If you're using the Intel QuickSync decoder, then thats a known bug. In any case, you should always mention what decoder you're referring to. (Software, CUVID, QuickSync, DXVA)

Using the 0.27 QS DLL, I managed to get ~400fps on this clip. The famous Samsung Oceanic Life clip now runs at 225fps instead of 145. LAV 0.45 ran the same clip at 156fps. BTW, ffdshow runs the Samsung clip at 270fps. All benchmarks used LAV splitter as source and were run twice.

this was not with quicksync itself and not to sound funny but that .ts has some decoding issue when using the software decoder am not sure what or even why that is but i would like nevcairiel to look into why this is if you need a good sample just ask but that is sample i posted is very slow at decoding and as you can see in the pics that 0.46 is slower |

uploaded a sample that is ~3m30s long and as you can see in this pic that yes 120 fps is slow say that i've been getting thing a easy ~600fps untill this decoding bug happened. by the way what was the problem nevcairiel? (i'll been using 0.45 untill this problem as been fixed) good .ts sample

Seems that cegy is right : there seems something wrong with the decoding (h264) from this file : in my benchmark I got about the same results.
Strange is that the decoding seems to be limited to 1 thread. I tested with 12 threads and with 1 thread : same result !! During the benchmark, I had a CPU load between 5-7 % (read from taskmanager), this should to be 50-70% or higher when testing with 12 threads. Tested on i7-970@3.7/ 6+6 cores. |

~77fps with LAV copy back ~84fps with LAV without copy back ~150fps with coreavc for a VC-1 .ts sample, I get ~35 fps with WMV DecoderDMO ~51 fpps with LAV copy back for some reason, LAV copy back works way better with VC-1 than with H.264 for me (meaning theres actually an improvement) -.- (maybe thats also because VC-1 CPU decoders are not multithreaded)

Hardware decoding isn't necessarily faster then CPU decoding on todays fast CPUs, but it does reduce the CPU load which can save power.
