[FFmpeg-user] DV to SD Blu-ray

Thu Jan 19 20:19:57 EET 2017

Hi List,

I'm a new user here and want suggestions for "best" ffmpeg syntax to 
transcode PAL 576i DV source files to compliant SD-BD_x264m2ts and/or 
SD-BD_mpeg2.m2ts.
The AVCHD-SD specification is possibly something that could be used
https://en.wikipedia.org/wiki/AVCHD#Specifications

My purpose is to
- archive this on 25GB-50GB BD-R discs in an suited format for future 
editing
- keep the source quality at relative high bit-rate (i.e AVC at 15 Mbps 
or MPEG-2 (I-frame?) at 25 Mbps)
- playback compliance with BD-players.
- keep by copy the DV LPCM audio if possible.

The closest samples as references I've found for encoding Blu-ray are these:

1) with x264 (video only)
http://www.x264bluray.com/home/576i-pal

2) with ffmpeg
http://forum.videohelp.com/threads/365667-FFmpeg-best-settings-to-encode-Blu-Ray?p=2332049&viewfull=1#post2332049

I want suggestions how to possibly "merge" relevant parameters from 1) 
x264 into 2) ffmpeg syntax ?

3) As a first attempt I tried to apply 2) mostly as is, but didn't 
succeed to get LPCM audio copied:
ffplay and VLC can playback the out video file SD-BD_x264.m2ts without 
Audio.
