== Available AVC/H.264 Codecs ==AVC/H.264 implementations are available atm already from x264, Nero, Apple, Sorenson, Elecard, Moonlight, VSS, mpegable, Envivio, Hdot264 (binary), DSPR, JM (reference software) (binary), ffmpeg, Philips, FastVDO, Skal, Sony and many more === Encoders ===* x264: the first publically available High Profile encoder, opensource (GPL) (Source), available for VFW: x264vfw, ffdshow (output .avi), as commandline: x264cli (outputs .mp4, .mkv, raw), mencoder (outputs raw, .avi) (Doom9's MeGUI) or ffmpegx264 supports 2pass, CABAC, Loop, multiple B-Frames, B-References, multiple Reference Frames, 4x4 P-Frame, 8x8 B-Frame Blocksizes, anamorphic signalling and High Profile: 8x8 dct and intra prediction, lossless and custom quant matrices* NeroDigital AVC: useable in Nero Recode2, outputs .mp4ND AVC supports 2pass, CABAC, (adaptive) Loop, multiple B-Frames, mulitple Reference Frames, weighted prediction, 8x8 P-Frame Blocksizes, 16x16 B-Frame Blocksizes, Adaptive Quant. (Psy High)* Sorenson: useable in Sorenson Squeeze 4, outputs .mp4,Sorenson supports 2pass, max 2 B-Frames, B-References, Loop and multiple Slices* Apple: useable in Quicktime 7, outputs .mp4, .3gp and .mov, totally slowuses 2pass, max 1 B-frame, Loop (0,0), P8x8,B8x8,I4x4, Adapt. Quant, 5 Slices, no CABAC, no Weighted Pred., no multi Ref.* JM: The AVC Reference Software offers in v9.3 Main and High Profile: B/SP-Frames, CABAC, Loop Filter, 4x4 Blocksizes, multiple Reference Frames, Adaptive Quant, Error Resilience, RDO, Lossless Coding, Custom Quants, Rate Control aso...* Hdot264: opensource (GPL) VFW version of the reference software by doom9 member charact3r, still based on a very old version of the reference (JM 4.0c)* VSS: free preview VFW Encoder (limited to 5 days), based on the reference encoder* Elecard: useable in Elecard Mobile Converter, outputs .mp4 and MainConcept's v2 encoder, outputs .264 and .mpg PS/TSnot publically available anymore:* Moonlight: useable in Moonlight's OneClick Compressor v1.1 and CyberLink's PowerEncoder, outputs .mpgMoonlight supports 1pass (VBR/CBR/Fixed Quants), CABAC, Loop, 2 B-Frames, 8x8 P-Frame Sizes, Adapt. Quant, PAR, Interlacing* MainConcept: was useable in the v1 encoder (adds a watermark), outputs .264 and .mpg PS/TS1pass (CBR/VBR/fixed Quants), P-Frame Reorder, CABAC, Loop, Multiple B-Vops, Multiple Ref, 4x4 P-Frame Sizes, PAR, RDO* mpegable: offered for some time a free VFW Encoder (not based on the reference), doesnt handle YV12mpegable supports 1pass (fixed quants) uses P-Frames only, 8x8 P-Frame Blocksizes, CAVLC only, Loop* Envivio: useable in 4Coder, outputs .mp4=== Decoders (comparison) ===* ffmpeg: opensource (LGPL), used e.g. in ffdshow (VFW and DShow decoder), mplayer and VideoLANsupports B-Frames, B-References, CABAC, Loop, Weighted Prediction and High Profile (8x8 dct and intra prediction, lossless)* CoreAVC* Apple: AVC decoding inside Quicktime 7, supports .mp4/.mov, very slowsupports only 1 B-Frame, CABAC, Loop but no mixed references, multiple B-frames and no interlacing* NeroDigital AVC: DShow Decoder and .mp4 Parser coming with Recode2supports Main and High Profile* VSS: preview VFW Decoder (limited to 5 days) and a DShow Decoder (limited to 30 days)VSS DShow supports .avi (with VSSH and H264 fourcc), CABAC, Loop, B-Frames* Elecard: available in Elecard's MPEG Player and MainConcept's v2 encoder* Envivio: not freely available AVC DShow decoder called EnvivioTV, handling AVC in .mp4 (since 2.0, current version: 2-1-181)* Philips: DShow AVC decoder freely available in the AVC Alliance player (handles raw AVC only)* FastVDO: time limited (5 minutes per video) High Profile DShow Decodernot publically available anymore:* Moonlight: DShow decoder/Parser handling AVC in .mpg, .mp4 and .264 available in Moonlight's MPEG Player v3.0supports Main and High Profile* MainConcept: the v1 preview offered a free DShow AVC decoder (adds watermark) and Parser handling AVC as .mpg PS/TS* mpegable: offered for some time a free VFW decoder (usable also in DShow), supports .avi (with DAVC fourcc)* Basic AVC Decoder in C, for an university project * Pegasus: not really compliant DShow AVC decoder
