[FFmpeg-user] to gather line 21 ( eia-608 ) into a f.cvs then f.srt

[jshupert at theppsgroup.com]

Frieds,
 
I have a 10 bit uncompressed avi that i have captured from a dbeta.
10bUncA41.avi
the dbeta was proven to have good line 21 [ 608 ] captioning.
meaning I see it on a decoder monitor.
line 21 vid bits are also seen in the file 10bUncA41.avi
 
the avi seems ok and is 486 , as we prove here
ffprobe 10bUncA41.avi

Input #0, avi, from '10bUncA41.avi':
  Duration: 00:00:10.58, start: 0.000000, bitrate: 227449 kb/s
    Stream #0:0: Video: v210 (v210 / 0x30313276), yuv422p10le, 720x486, 224433 k
b/s, 29.97 fps, 29.97 tbr, 29.97 tbn, 29.97 tbc
    Stream #0:1: Audio: pcm_s24le ([1][0][0][0] / 0x0001), 48000 Hz, 2 channels,
 s32 (24 bit), 2304 kb/s
 
My Goal is to capture line 21 data - decode it into a csv
that is I wish to ultimately end in a file.srt  that has the captioning
 
I am doing the following
( what i call complete console out )
 
G:\ln21>c:\09_bin\ffprobe -f lavfi -i movie=10bUncA41.avi,readeia608 -show_entri
esframe=pkt_pts_time:frame_tags=lavfi.readeia608.0.line,lavfi.readeia608.0.cc,la
vfi.readeia608.1.line,lavfi.readeia608.1.cc -of csv > 10bUncA41.csv

as we can see it fails
 
is that because my ffprobe binary was not compiled with
lavfi  or is it something else / more ?
 
 
thanks in advance
 
best wishes
