Hi,
I'm working on a couple of NTSC DVDs, and even with the latest version
of transcode (ver. 1.0.3), I'm getting conflicting framerate readings
from tcprobe.
When I run tcprobe on the DVD ("tcprobe -H 100 -i /dev/dvd"), I get the
following:
[tcprobe] summary for /dev/dvd, (*) = not default, 0 = not detected
import frame size: -g 720x480 [720x576] (*)
aspect ratio: 16:9 (*)
frame rate: -f 23.976 [25.000] frc=1 (*)
audio track: -a 0 [0] -e 48000,16,2 [48000,16,2] -n 0x2000
[0x2000]
audio track: -a 1 [0] -e 48000,16,2 [48000,16,2] -n 0x2000
[0x2000]
audio track: -a 2 [0] -e 48000,16,2 [48000,16,2] -n 0x2000
[0x2000]
Even after using tccat and running tcprobe on the mpegpes video, tcprobe
still reports a framerate of 23.976.
However, when I use transcode, and pass it "-f 23.976,1" or even "-f
24,1" or "-f 24,2", it is unable to convert the video. mplayer, on the
other hand, reports a framerate of 29.970 reading from both the DVD and
from the tccat'd MPEG file. mplayer output:
MPEG-PS file format detected.
VIDEO: MPEG2 720x480 (aspect 3) 29.970 fps 7500.0 kbps (937.5
kbyte/s)

Opening video decoder: [mpegpes] MPEG 1/2 Video passthrough
VDec: vo config request - 720 x 480 (preferred colorspace: Mpeg PES)
Could not find matching colorspace - retrying with -vf scale...

The selected video_out device is incompatible with this codec.
Try appending the scale filter to your filter list,
e.g. -vf spp,scale instead of -vf spp.
VDecoder init failed :(

==========================================================================
when I use "-f 29.970" or "-f 29.970,4" with transcode, the input is
converted properly.
Is this a bug in transcode? If so, what can I / we do to fix it?
