Hi,

is there a plan to add Support for H265/HEVC?

Yes. We just didn't get to it yet because client update has higher priority.

Reconverting 13 TBs of videos to H265 from H264 could be fun!

Could also be bit counterproductive since no iOS device currently supports H.265 natively.

I'm more interested in the file size reduction. At 40 TBs and a 10 - 20% savings is significant on the footprint :)

Any chance there is movement on this, the big file size reduction is really appealing to me, so I'm eager to get things moved over to the new format :)

It's targeted for 2.1 (although probably won't be in fist alpha/beta versions).

So...now the question is, does anyone have a process for converting a large amount of files with good quality output (command line totally fine)?  My understanding is that there are quite a few parameters to tweak around with for the command-line conversion, so if someone has found something that works for them, I'd be very very grateful for the advice or example.

were you able to find an example?

I've created both a 480p and 1080p file in the format and can confirm it works! Now I just need to figure out how to get pytivo to behave with the file format before converting 17TB of videos...

Given current state of H.265 encoding it's probably going to take a while to transcode 17TB of videos :)

I also have figured out how to do it, I'm using ffmpeg to carry out the conversion.  I'm using the following script to convert a folder of video files:
for %%A in (*.mp4 *.mkv *.m4v *.avi *.wmv *mpg) do (
ffmpeg -i "%%A" -map 0 -c copy -c:v libx265 -preset slow -crf 28 "265_%%A"
)
pause
This appends a "265_" to the filenames so I can track how far the conversion has gotten, then I use this to rename them after I've deleted the old h264 files
@echo off
setlocal enabledelayedexpansion
for %%a in (265_*) do (
  set oldname=%%a
  ren "!oldname!" "!oldname:~4!"
)
pause
You can also use the following script to check if any files currently are already in H.265 format (it will output HEVC in the format line)
@echo off
del /Q fileinfo.txt
for %%A in (*.mp4 *.mkv *.m4v *.avi *.wmv *.mpg) do (
ffprobe -v error -show_entries "format=filename : stream=codec_name" -select_streams v "%%A" >> fileinfo.txt
)
pause
