| .SYNOPSIS | |
| Transcode all files in a folder recursively with a given file extension. | |
| .DESCRIPTION | |
| Transcode all files in a folder recursively with a given file extension. | |
| Prints the name of each file it transcodes. | |
| Uses ffpb to display a progress bar if possible. | |
| .PARAMETER path | |
| Required. Specifies the folder path to recursively search for files. | |
| .PARAMETER inputExtension | |
| Specifies the extension. "mp4" is the default. | |
| .PARAMETER outputExtension | |
| Specifies the extension. "mkv" is the default. | |
| .PARAMETER videoCodec | |
| Specifies the video codec. "libsvtav1" is the default. | |
| .PARAMETER crf | |
| Specifies the constant rate factor. "30" is the default. | |
| .PARAMETER audioCodec | |
| Specifies the audio codec. "copy" is the default. | |
| .PARAMETER notRecursive | |
| Specifies if it should scan recursively for files. "false" is the default. | |
| .PARAMETER dryRun | |
| Specifies if it should perform a dry run. "false" is the default. | |
| .PARAMETER deleteOriginal | |
| Specifies if it should delete the original file after transcoding. "false" is the default. | |
| .INPUTS | |
| None. | |
| .OUTPUTS | |
| None. | |
| .EXAMPLE | |
| PS> MassFFMpegConvert -path .\Videos | |
| Transcoding mp4 to mkv with c:v libsvtav1, CRF 30, c:a copy | |
| Transcoding .\Videos\test.mp4 | |
| test.mp4: 100%|#############| 600/600 [00:05<00:00, 120.0 frames/s] | |
| Done! ✅ | |
| .EXAMPLE | |
| PS> MassFFMpegConvert -path .\Videos -inputExtension webm -outputExtension mp4 -videoCodec libx264 -crf 20 -audioCodec aac | |
| Transcoding webm to mp4 with c:v libx264, CRF 20, c:a aac | |
| Transcoding .\Videos\test.webm | |
| test.webm: 100%|#############| 600/600 [00:05<00:00, 120.0 frames/s] | |
| Done! ✅ | |
| .EXAMPLE | |
| PS> MassFFMpegConvert -path .\Videos -dryRun | |
| Transcoding mp4 to mkv with c:v libsvtav1, CRF 30, c:a copy | |
| Transcoding .\Videos\test.mp4 | |
| Done! ✅ | |
| # Notice how nothing is actually transcoded. It's just a dry run. | |
