As FFMpeg (then)
would not allow to
mux PCM or remux
MPG to M2TS, I <br>
tested tsMuxer,<br>

That is,
suggestion how to
merge/customize
the newer ffmpeg
HDV to <br>
Blu-ray procedure<br>
ffmpeg -i hdv.m2t
-c:v copy -c:a
pcm_bluray
-mpegts_m2ts_mode
1 output.mts<br>
</font> <font face="Courier New,
Courier,
monospace"><br>
for SD-DV to keep
it interlaced and
get
dv28_25mbps.m2ts
muxed directly?<br>
</font> <font face="Courier New,
Courier,
monospace"><br>
------------------<br>
</font> <font face="Courier New,
Courier,
monospace"><br>
I did a first try
with the following
line, without
taking care of <br>
25mbps, but got
lost the pcm audio
to a privat stream
(change mode?).<br>
Additional the
vido is not kept
interlaced.<br>
