ffmpeg errors with comcut

[opoplawski]

Googling around on that error it seems that the input file must have bad timestamp values that ffmpeg cannot handle.

[opoplawski]

The "Using AVStream.codec to pass codec parameters to muxers is deprecated, use AVStream.codecpar instead" message at least seems to be an internal ffmpeg issue and should be harmless.

Here's the edl:

$ cat All\ Our\ Yesterdays.edl
0.00    18.92   0
242.41  496.39  0
874.36  1145.29 0
1790.79 2002.40 0
2932.81 3180.55 0
3692.02 3932.42 0
4187.37 4200.95 0

And the ffmeta:

$ cat All\ Our\ Yesterdays.ffmeta
;FFMETADATA1
[CHAPTER]
TIMEBASE=1/1000
START=0
END=0
[CHAPTER]
TIMEBASE=1/1000
START=0
END=223490
[CHAPTER]
TIMEBASE=1/1000
START=223490
END=601460
[CHAPTER]
TIMEBASE=1/1000
START=601460
END=1246960
[CHAPTER]
TIMEBASE=1/1000
START=1246960
END=2177370
[CHAPTER]
TIMEBASE=1/1000
START=2177370
END=2688840
[CHAPTER]
TIMEBASE=1/1000
START=2688840
END=2943790

So the first issue seems to be a zero length section at the start for some reason.

+ echo ';FFMETADATA1'
+ IFS=' '
+ read -r -a line
+ (( i++ ))
+ end=0.00
++ echo 0.00 - 0
++ bc
++ awk '{printf "%f", $0}'
+ duration=0.000000
+ startnext=18.92
+ hascommercials=true
+ echo '[CHAPTER]'
+ echo TIMEBASE=1/1000
++ echo '(0 - 0) * 1000'
++ bc
++ awk '{printf "%i", $0}'
+ echo START=0
++ echo '(0.00 - 0) * 1000'
++ awk '{printf "%i", $0}'
++ bc
+ echo END=0
+ chapterfile='All Our Yesterdays.part-1.ts'
+ [[ ! -z '' ]]
+ tempfiles+=("$chapterfile")
+ concat='|All Our Yesterdays.part-1.ts'
+ ffmpeg -nostdin -i 'All Our Yesterdays.mpg' -ss 0 -t 0.000000 -c copy -y 'All Our Yesterdays.part-1.ts'

maybe this is normal.

This I think is the real issue:

++ bc
++ echo 0 + 18.92 - 0.00
+ totalcutduration=18.92
+ start=18.92
+ IFS=' '
+ read -r -a line
+ (( i++ ))
+ end=242.41
++ echo 242.41 - 18.92
++ awk '{printf "%f", $0}'
++ bc
+ duration=223.490000
+ startnext=496.39
+ hascommercials=true
+ echo '[CHAPTER]'
+ echo TIMEBASE=1/1000
++ echo '(18.92 - 18.92) * 1000'
++ awk '{printf "%i", $0}'
++ bc
+ echo START=0
++ echo '(242.41 - 18.92) * 1000'
++ bc
++ awk '{printf "%i", $0}'
+ echo END=223490
+ chapterfile='All Our Yesterdays.part-2.ts'
+ [[ ! -z '' ]]
+ tempfiles+=("$chapterfile")
+ concat='|All Our Yesterdays.part-1.ts|All Our Yesterdays.part-2.ts'
+ ffmpeg -nostdin -i 'All Our Yesterdays.mpg' -ss 18.92 -t 223.490000 -c copy -y 'All Our Yesterdays.part-2.ts'

I think it has something to do with a zero-length chapter. Try manually editing the edl and removing the zero length chapter and rerun comcut.

I thought I addressed this before. But apparently not.

[BrettSheleski]

I also see that comcut is still using bc under the hood. @Reed97123 submitted a fix which removed bc and uses awk instead for comchap for a very similar issue. See: #12 for details of that change.

[BrettSheleski]

I removed calls to bc in favor of using awk and also added logic to skip zero-time chapters. See 517116e and 517116e.

Please see if this fixes your issue.
