Description

LSMASHSource is a source plugin for AviSynth/AviSynth+. It uses FFmpeg (libavcodec) to decode all supported audio and video formats. For a complete list see official FFmpeg documentation.

Requirements

• AviSynth 2.6.0 or greater
• Supported color formats: RGB24, RGB32, YUY2, Y8*, YV12, YV16*, YV24*, YV411*

* These additional planar colorspaces are not available in AviSynth 2.5.8.

• Microsoft Visual C++ 2013 Redistributable Package (x86 / x64)

** vcredist_x86.exe is required for L-SMASH-Works-32bit

** vcredist_x64.exe is required for L-SMASH-Works-64bit

Filter	Description	Color format
LSMASHAudioSource	Uses libavcodec as an audio decoder and L-SMASH as a demuxer. Recommended for MP4, MOV, ISO Base Media and its derived file formats. One advantage over LWLibavVideoSource and FFmpegSource is that it doesn't need to create an index file for its supported formats.

LWLibavAudioSource	Uses libavcodec as an audio decoder and libavformat as a demuxer.
LWLibavVideoSource	Uses libavcodec as a video decoder and libavformat as a demuxer. Supports video codecs LSMASHVideoSource does not – for example MPEG-4, UT Video, Lagarith, and animated GIF and PNG.	RGB24, RGB32, YUY2, Y8, YV12, YV16, YV24, YV411

r935+31-20190818	L-SMASH-Works-r935+31-20190818.7z		LWLibavVideoSource no longer indexes audio streams. It reduces both the file size and parsing time of the index file. LWLibavAudioSource will re-create the index file for the source file which was already indexed by LWLibavVideoSource so as to index audio streams. Print indexing progress to stdout. Tell lavf to discard unwanted packets so they needn't be demuxed. Remove InputFilePath field from the index file. It's unnecessary and troublesome when users rename or move the source file. Automatically re-create the index file when the file size or the last modification time of the source file doesn't match. Change the printing of index progress from stdout to stderr so as to avoid corrupting pipe data accidentally[1] Compiled by HolyWu
r935+26-20190811	L-SMASH-Works-r935+26-20190811.7z		Update to FFmpeg 4.2. Add parameter cachefile. Compiled by HolyWu
r935+26-20190712	LSMASHSource-Release_r935+26.zip		Integrated patches from multiple forks. The same patch set HolyWu used, which was copied from enccc, and one more patch to use swresample instead of avresample, which was copied from l33tmeatwad.[2] Compiled by MeteorRain
