MVCsource v3.0.0 – 3D MVC/AVC/VC-1/MPEG2 Avisynth Source Plugin (Intel Quick Sync)

[pistacho]

As part of BDtoAVCHD software I developed this plug-in for optimize Blu-Ray 3D to SBS/TAB conversions. Is based on Intel Media SDK 2021 R1 and can be used on all systems (SW acceleration) or on Intel Graphics systems (HW acceleration - Intel Quick Sync). Can decode elementary AVC/MVC both streams combined in the same file or in separated files.

Now I opened this thread so it's can be used for more purposes/applications in addition to original usage.

Current version can also decode 2D HEVC/AVC/VC-1/MPEG2 streams (included UHD 10 bit color for HEVC).

PARAMETERS

MVCsource("X:\path_to_AVC.h264", "X:\path_to_MVC.h264", number_of_frames, output_format)

number_of_frames:  number of frames that contains .h264 files

output_format:

 0 : AVC frames only
 1 : MVC frames only
 2 : interleaved AVC-MVC frames (AVC odd)
-2 : interleaved MVC-AVC frames (AVC even)

Notes:

• If number_of_frames specified is lower that actual number of frames in .h264 file, output is trimmed. Also if is greater additional black frames are inserted to complete requested number of frames.
• Output is already YV12 color format, please do not insert ConvertToYV12() in scripts.
• Correct framerate is taken from stream, please do not insert AssumeFPS() in scripts.
• In interleaved left-right direct outputs frame rate is doubled (2x). It's not a bug! That's the functionality that is intended.
• From version 2.0.0 it's also possible to specify a 2D elementary stream (AVC/VC-1/MPEG2) in the first parameter. In this case must leave the empty second parameter "" and output_format = 0.
• NEW: from version 2.8.0 can also decode 2D HEVC elementary stream (only using HW mode).
