VirtualDub 1.5.5 (experimental)

Ir parādījusies VirtualDub 1.5.5 (experimental) 658KiB jeb eksperimentālā versija. Autors informē, ka speciāli priekš Intel P4 procesoriem paredzētās versijas nebūs tāpēc, ka Intel C/C++ 6.0 taisot gļukus.

VirtualDub 1.5.5 is out on SourceForge and is the first version that I’ve explicitly tagged as “experimental.” The primary reason is the new display code — 1.5.5 is the first version to use DirectDraw by default, the result of which is a significant increase in rendering speed as well as a usable stretch. (Right-click the panes for the new options.) 1.5.4 is pretty stable at this point and as such it’s a good idea to split versions into stable and development releases. So please try 1.5.5 and report the problems, and if you have problems, use 1.5.4. 1.5.5 does add a few more workarounds for various problems as well as some optimizations for direct stream copy mode, so if all goes well it should work better than 1.5.4.

Bēdīga ziņa būs komerckodeka DivX 5.1 cienītājiem, jo VirtualDub autors pirms nedēļas pasūtīja šo kodeku divas mājas tālāk, jo DivXNetworks prātvēderi ir uzlikuši aizsardzību savam meistarojumam, kas liedz iespēju to “debugot” (vienkāršā valodā – testēt programmu un redzēt kļūdu paziņojumus). Lai gan tas nenozīmē, ka vairs nevarēs spiest filmas ar šo kodeku, vienkārši autoram būs pie kājas jūsu vaimanas par to, ka kaut kas neiet.

My announcement for the week is that I will not be supporting the use of DivX 5.1 in any way, shape or form in VirtualDub.

Current build (Version 1.5.5):
[features added]
* Partial Unicode support — you can now open and save files using Unicode filenames.
* “Chroma smoother” video filter refilters point-sampled chroma with linear interpolation.
* Single-stream cut & paste. (Be patient….)
* Improved performance of AVI parser, particularly for Direct mode streaming.
* Improved performance of bicubic upsampler.
* Audio filter graph now shows intermediate audio formats on connections.
* Audio filters can now be plugins.
* New MPEG-1 video core (Meia) — full vertical clipping. Horizontal clipping is still by macroblock.
* Rewrote display code — DirectDraw support is now automatic.
* Log windows now have a context menu for clearing, copying, and saving the log text.
* Modified AVI2 indexing to relax indexing restrictions somewhat, although it’s still not user configurable yet.

[bugs fixed]
* Hex editor occasionally displayed the wrong data after a find or save command.
* “Attach extension” option didn’t work for signpost save dialog.
* Fixed crash when I/O errors occur during a processing operation, and then occur again when attempting to gracefully finalize the partial output file.
* “Clear” didn’t work in audio filter graph.
* Fixed I/O errors when attempting to push audio forward with advanced audio filtering enabled.
* “Go to” command didn’t handle timestamps with fractional seconds that only had 1 or 2 decimal digits.
* “General convolution” generated bad code for factors of 2, 4, and 8 when dynamic compilation was enabled.
* Interleave periods of zero are no longer allowed.
* Added workaround for crash or hang when compressing with the “3ivx D4 4.0.4” video codec.
* Fixed non-interleaved save mode and made it cooperate with segmentation.
* Added workaround for heap corruption when processing audio in advanced mode sourced from some versions of Avisynth.
* Clarified DivX warning to note that it doesn’t apply to the DivX 4+ codecs.
* Fixed filter cropping not working properly when “motion blur” was the first filter in the chain.

    Alans a ir kaads manuaalis kaa kvalitatiivi saspiest bet lai aiznjemtu maz vietas. Citaadi ierakstu no video kameras uz hdd 8 min, saspiezju ar DIVX4.12 labaakajaa kvalitaate un tas aiznjem 380 MB
    P.S. me tikai nesen saaka par video kompreseeshanu intereseeties.

    VirtualDubMod ir vajadziigs tikai gadiijumos, kad mpeg2 jaaspiezh. labaak gan izmantot d2v un frameserver caur avisynth – nebuus pilniibaa jaapaarkompresee un izpaliks YUV->RGB.
    Par divX – 3.11 ar NanDub ir labaakais. Xvid ir ok, bet diemzheel biezhi gljuko uz dazhaadiem kompjiem 🙁 4., 5. sako, jo bik pa lielu ir pixelju interpolaacija un daudz informaacijas no kadra vispaar pazuud (kraasu intensitaate, etc).
    P.S. Protams, ka tas ir tikai mans viedoklis 🙂

    Atlausos veelreiz atgaadinaat, ka kvalitaate ir subjektiivs jeedziens. Ja jau reiz ir shie nebeidzamie striidi, kursh labaaks, tad atliek vien secinaat, ka iistas starpiibas (kalitaates zinjaa) nav un katrs redz to, ko grib redzeet. Dazhiem labaak patiik DivX 5 briiziem mazliet izsmeereetais atteels, citi labaak pieciesh blokus utt. Jebkuraa gadiijumaa atskiriibas var redzeet tikai tad, ja divus no viena avota iekodeetus failus skataas vienlaiciigi, vai iisi vienu peec otra.. Tapeec iesaku padomaat – vai (varbuuteejais!) nelielais ieguvums ir taa veerts, ja lielaakaa dalja to pat nepamana? No mana viedoklja vajadzeetu izveeleeties kodekus ar kuriem iekodeeto materiaalu vareetu noskatiities vislielaakaa dalja cilveeku, respektiivi, visplashaak izplatiitos, visaatraakos un visstabilaakos. Peec shaadas atlases praktiski paliekam pie DivXiem (XviD tik tieshaam ir gljukains). Optimaali tas buutu DivX 3.11, tachu ja pinkereeshanaas ar Nandub skiet paaraak sarezgiita var izmaintot arii DivX 5, jo lielaakaa dalja tomeer lieto DivX 5 dekoderi. Es protams nepretendeeju uz augstaako patiesiibi – ja kljuudos zinjojiet.
    P.S. Zheel ka “Xvid valda” bljaaveeji neko vairaak arii nevar pateikt. Tas laikam vienkaarshi tagad modee – izmantot XviD.

    Protams, XviD nav ideaals, tach uz mana kompja darbojas stabili un pietiekami aatri, arii kaa dekoderi izmantoju ffdshow, nevis maazhojos ar DivX’iem (noiets etaps, shkjiet).
    Protams, ljoti labi buus, ja [arii???] jaunajos VirtualDub’os un kodekos tiks stiprinaata tradiicija ievietot dazhaadas assembler’iskas in instruction’iskas optimizaacijas, t.i. FP, SSE, SSE2, 3DNow! un naakamaas paaudzes…

    to whatever:
    Esmu, jau esmu saliidzinaajis n-tos variantus, taapeec arii taa droshi saku, ka 3.11 ir labaakais arii no Tevis piemineetaas kodeka stabilitaates aspekta. Par 5-to divX – nav probleemu kodeet ar 3.11, jo visi naakamie (4.,5.) maak dekompreseet 3.11, otraadi gan nee. 🙂

    VirtualDub 1.5.4… neierullee, jo never pilniibaa mpeg failus valjaa, bet taapat arii neierullee DivX 5.1, jo kropljo kompreseejamo materiaalu (ne visus – atkariibaa no kompreseejamaa materiaala) un visiem video failiem saakums kaut kaads gljotains ar kubikiem. Nezinu kas tas par experimentaalo versiju, bet vinju maajas lapaa jau ir 1.5.6… versija. Aatri gan taas lietas notiekas 😉
