DVD compliant MPEG-2 Video and PCM Audio
I thought to create a DVD compliant MPEG2 Video and PCM Audio using the same principles as earlier for BD video. The sample source input is a raw DV25 PAL file which includes PCM audio: ffprobe -hide_banner dv28.dv [dv @ 0x55dc6248cf00] Estimating duration from bitrate, this may be inaccurate [dv @ 0x55dc6248cf00] Could not find codec parameters for stream 0 (Video: dvvideo, none, 25000 kb/s): unspecified size Consider increasing the value for the 'analyzeduration' (0) and 'probesize' (5000000) options Input #0, dv, from 'dv28.dv': Metadata: timecode : 00:00:00:00 Duration: 00:02:16.64, start: 0.000000, bitrate: 28800 kb/s Stream #0:0: Video: dvvideo, none, 25000 kb/s, SAR 16:15 DAR 0:0, 25 fps, 25 tbr, 25 tbn Stream #0:1: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s Unsupported codec with id 24 for input stream 0 1) ffmpeg encoding DV to MPEG-2 video and copy PCM audio as is to a VOB/MPG format: 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 ............. a lot of warning messages [vob @ 0x55b227ae4240] packet too large, ignoring buffer limits to mux it [vob @ 0x55b227ae4240] buffer underflow st=1 bufi=6744 size=7680 .................. frame= 3416 fps=400 q=3.6 Lsize= 161296kB time=00:02:16.64 bitrate=9670.2kbits/s speed= 16x video:133611kB audio:25620kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 1.296714% I've tried various bufsizes and muxrate sizes, but still the warning messages arise. Suggestions? ffprobe -hide_banner dv28.mpg Input #0, mpeg, from 'dv28.mpg': Duration: 00:02:16.64, start: 0.540000, bitrate: 9670 kb/s Stream #0:0[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, bottom first), 720x576 [SAR 16:15 DAR 4:3], 25 fps, 25 tbr, 90k tbn Side data: cpb: bitrate max/min/avg: 8000000/0/0 buffer size: 20004864 vbv_delay: N/A Stream #0:1[0xa0]: Audio: pcm_dvd, 48000 Hz, stereo, s16, 1536 kb/s The resulting dv28.mpg file seems to playback fine with video and audio in ffplay and VLC 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 du -sh dv28.* 470M dv28.dv 158M dv28.mpg 164M dv28.ts Any idea how to create a simple DVD iso with tsMuxer command line if possible, or with other tools?
