I thought to create a DVD compliant MPEG2 Video and PCM Audio using
the same principles as earlier for BD video.<br>
<br>
The sample source input is a raw DV25 PAL file which includes PCM
audio:<br>
<br>
<blockquote>ffprobe -hide_banner dv28.dv<br>
[dv @ 0x55dc6248cf00] Estimating duration from bitrate, this may
be inaccurate<br>
[dv @ 0x55dc6248cf00] Could not find codec parameters for stream 0
(Video: dvvideo, none, 25000 kb/s): unspecified size<br>
Consider increasing the value for the 'analyzeduration' (0) and
'probesize' (5000000) options<br>
Input #0, dv, from 'dv28.dv':<br>
Metadata:<br>
timecode : 00:00:00:00<br>
Duration: 00:02:16.64, start: 0.000000, bitrate: 28800 kb/s<br>
Stream #0:0: Video: dvvideo, none, 25000 kb/s, SAR 16:15 DAR
0:0, 25 fps, 25 tbr, 25 tbn<br>
Stream #0:1: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s<br>
Unsupported codec with id 24 for input stream 0<br>

1) ffmpeg encoding DV to MPEG-2 video and copy PCM audio as is to a
VOB/MPG format:<br>
<br>
<blockquote>ffmpeg -i dv28.dv -c:v mpeg2video -refs 1 -bf 2 -b:v 8M
-maxrate 8M -minrate 8M -bufsize 20M -muxrate 11M -dc 10 -c:a
pcm_s16be -f vob -flags +ilme+ildct dv28.mpg<br>
.............<br>
a lot of warning messages<br>
[vob @ 0x55b227ae4240] packet too large, ignoring buffer limits to
mux it<br>

<br>
I've tried various bufsizes and muxrate sizes, but still the warning
messages arise. Suggestions?<br>
<br>
<blockquote>ffprobe -hide_banner dv28.mpg<br>

The resulting dv28.mpg file seems to playback fine with video and
audio in ffplay and VLC<br>
<br>
Afterwards I loaded it as input to tsMuxer, and muxed it to dv28.ts,
in lack of a button to create an DVD ISO similar like simple Blu-ray
ISO<br>
<br>
<blockquote>du -sh dv28.*<br>
470M dv28.dv<br>
158M dv28.mpg<br>
164M dv28.ts<br>
</blockquote>
<br>
Any idea how to create a simple DVD iso with tsMuxer command line if
possible, or with other tools?<br>
