<h1>HDV on a Blu-ray Disc Without
Re-encoding </h1>
<p> An MTS file is a video file
saved in the high-definition
(HD) MPEG Transport Stream video
format, commonly called AVCHD.
It contains HD video compatible
with Blu-ray disc format and is
based on the MPEG-2 transport
stream. MTS files are often used
by Sony, Panasonic, Canon and
other HD camcorders. Legal input
for Video – MPEG1VIDEO,
MPEG2VIDEO, H264; Audio – MP1,
MP2, AC3, AC3PLUS, DTS, TRUHD. </p>
<p>Note, mp2 and mp1 audio codecs
are valid for transport stream
itself but not as on-disk format
for Blu-Rays.</p>
<p>In this case you still can save
original video by using ffmpeg's
switches</p>
<p> -c:v copy -c:a ac3 , while
outputting into another temporal
ts container.</p>
<p>{waiting for Terje's results on
pcm_bluray case}</p>
<p><br>
</p>
<p>---</p>
<p><br>
</p>
<p>I think all m2ts files you used
for testing were h264/aac (or
ac3), not from-camcoder HDVs
with mpeg2 video/mp2 audio. </p>
<p>you can try HDV-in-mov from
this folder as ffmpeg test file,
I think</p>

<div dir="auto">oh, this is not mp2 audio

<div dir="auto">so this line work, note
mpegts_m2ts_mode switch for enabling more

mux audio into private stream - good luck
getting it back!</div>

I can try to dig and test further into this matter later
this month - or possibly more realistic next month. <br>

Some thoughts in advance:<br>
<br>
Would it possibly be better/clear to differ/split
between the formats, HDV video on tape (M2T container)
and the successor H264/AVC(HD) video on disk?<br>

Possibly you still have the probably little longer HDV
1080i sample file, "20081103140154.m2t" we used for the
HDV format patch here<br>

And if Phyllis has access to a Blu-ray disc burner and
BD hw player, testing could possibly start sooner(?)<br>

<p> For creating a blu-ray disc,
if you have HDV MPEG-2 media
that is in blu-ray format, you
can save the original quality of
your work, rather than rendering
it to another format. </p>

if bdwrite still works with
bluray pcm audio as produced by
ffmpeg 5.1+}</p>

I forgot one question:<br>
Will it be possible and how to access and use ffmpeg-5.x included
with Cin-GG in a terminal as usual?<br>
<br>
The latest openSUSE Leap 15.4 distro I use, has so far no official
ffmpeg-5.x package or codec enabled from Packman.<br>
I have add-installed ffmpeg-5.1.2 from OBS (Open Build Service), but
don't know if it works. <br>
