Scripts to convert media to x265
|
|
|
|
These are mostly a hack job since I'm trying to save space for my media by converting things into HEVC.
|
|
|
|
I really need to make a unified script for the edge cases, but I haven't. Feel free to send a PR if you to something. I
|
|
also want to add AMF support, but have not gotten that to work right yet.
|
|
|
|
The nvidia example is 265 the other scripts use vaapi (intel/amd) to do the HW HEVC encoding. I haven't done much with
|
|
the NVIDIA in a few years, so it's kinda stale.
|
|
|
|
265_system is the one that you should use if you're going to use it.
|
|
|
|
265_qsv uses Intel Quick Sync to use your igpu.
|
|
|
|
You'll have to compile ffmpeg with the --enable-libmfx option to enable qsv support. I think jellyfin/emby include qsv
|
|
with their builds too.
|
|
|
|
Adjust the -global_quality flag to change the quality. The lower the number the higher the bitrate. 20 seems to be a
|
|
good balance of quality vs file size.
|
|
|
|
Here's the options I used to compile it and make qsv work for me:
|
|
|
|
```text
|
|
--enable-gpl --enable-version3 --enable-gnutls --enable-libaom --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-nonfree --enable-libmfx
|
|
```
|
|
|
|
I use it with parallel to do multiple files at once like this:
|
|
|
|
```shell
|
|
parallel 'find {} -type f -maxdepth 5 -regex ".*\.\(mkv\|mp4\|wmv\|flv\|webm\|mov\|avi\|m4v\|ts\m2ts\)"' ::: /mnt/Movies /mnt/TV | parallel --jobs 4 --progress ~/convert265/265_system {}
|
|
```
|
|
|
|
Change the --jobs flag to the number of files your system can handle at once. I think 4 is a sane number for older/lower
|
|
end NAS devices.

YMMV // Caveat Emptor // And have an average day :|
