There have been some changes to libavcodec regarding MPEG in revision 1391. See if the problem occurs with FFmpeg as well.

I just encountered an ffdshow incompatibility issue which should be easily resolvable:
If you try to play OGG Vorbis content (.ogg audio files) with Haali Media Splitter being used as the source/parser filter, ffdshow refuses connection. The CLSID subtype on the output pin of the haali filter is "{8D2FD10B-5841-4A6B-8905-588FEC1ADED9}". I think it's just a matter of accepting the connection, no? |

Hmm, forgive my inexperience, but I have not used ffmpeg directly before. To give it a try, I got the latest build I could find, ffmpeg.rev9767.7z, but its date (July 20th) seems to put it before the problem occurred. I tried it anyway, using "ffplay", and there was not any problem. I don't have the tools to compile it directly.

Problem with the following installation file by clsid:
ffdshow_rev1413_20070810_clsid.exe When installing a first time, I check all video formats. When installing a second time, the following video formats get unchecked automatically: *DivX *Xvid *Generic MPEG-4 This is using the English language setup.

more intersting if the colorspace is yuy2, the video is cropped and instead of resized. sometime mpc will freeze by changing the "multiply by" value. Quote:

The ffdshow FLAC decoder doesn't seem to like 8 channels. Sound is distorted with ffdshow tryouts. Here's a sample file:

libavcodec seems to have some trouble outputting non-mod16 video. I used Fraps to capture some video at 1680x1050 and the video looks like this when played back with ffdshow or mplayer. The problem showed up in both the uncompressed video and xvid compressed version, but disappeared when fraps own codec and xvid were used to decompress.
screencap1 screencap2 [edit] Seems like XviD used YUY2 colorspace for output and when i forced ffdshow to use it everything was fine. A Nvidia video driver bug with YV12? Last edited by DeeGee; 15th August 2007 at 11:04. |

Hi all,
I have fixed the heavy stutterring issue with DTS streams with high bitrate : revision 1420. This usually concerns blueray videos that hold high quality sound track Please report me if there are regressions on other numeric formats Quote:

For the record, ffdshow-tryouts DO NOT work on libavcodec's video decoding speed. That's the domain of ffmpeg and Mplayer, so complain to them, not us. However, do bear in mind that the VC-1 decoder is still in it's infancy, so is bound to be slow decoding. It will get faster as it's more optimised.

Yep exactly even the biggos implementations are slow yet for VC-1 and have no Hardware accelleration (Mainconcept/Elecard) (Sonic most of their stuff is based on Mainconcept/Elecard research) so in that regards Libavcodecs VC-1 Decoder does quiet well compare :P (Cyberlinks Decoder seems more advanced but it seems only working inside powerdvd :P)

This sample http://rapidshare.com/files/49123646...acbug.mkv.html (22mb)(rapidshare) seems to cause an access violation after playing a few seconds.
It only happens with realaac, libfaad2 decodes it just fine. Can someone confirm this? using ffdshow rev 1371 here |

FFdshow video filter multithreading
Is there any work towards getting ffdshow filters multithreaded? Couldn't different tasks be run on different cores eg. decoding and resize on core 0 and other filters + colorspace conversion on core 1?

In all case, I still have problems when re-installing ffdshow. Here is an example with screencaptures. STEP 1 = Uninstall ffdshow STEP 2 = Install ffdshow (and reset all default) STEP 3 = Install ffdshow again On first install I get: On second install I get: So you will notice that on second installation, many checkboxes have disappeared: * CorePNG, MS Video 1, MSRLE, Techsmith, Truemotion * ASV1/2, CYUV, ZLIB, 8BPS, LOCO, MSZH, QPEG, WNV1, VCR1 * CamStudio, ZMBV, Ultimotion, VIXL, AASC, IV32, FPS1, RT21 * ADPCM, MS GSM, Truespeech * Always skip H.264 inloop deblocking
