No, it's packet duration, not tmcd frame duration, my patch have do nothing
for that.(see movenc.c:2348). In addition, for timecode, I don't think vfr is
supported.
The tmcd track just contains one packet with the frame number(4byte), so the
packet data is used by start of timecode. So I set the dts/pts is avoid the
following code think it's invalid packet. If you wonder the patch will change
something, I can update the patch keep packet duration to default zero, then
we can the fate data untouched, for the following track_duration will use it
and make the crc of output is different.

Fix below error message when timecode packet is written.
"Application provided duration: -9223372036854775808 / timestamp:
-9223372036854775808 is out of range for mov/mp4 format"
try to reproduce by:
ffmpeg -y -f lavfi -i color -metadata "timecode=00:00:00:00" -t 1 test.mov
Note although error message is printed, the timecode packet will be
written anyway. So
the patch 2/2 will try to change the log level to warning.
The first two test case of fate-lavf-ismv have timecode setting, so the
crc of ref data is different.
Fixes ticket #9488

You stated that you think that both files are valid, but you also said
that you don't even know what this byte that is different actually means.

The text about Timecode Sample Description reads as follows: "Frame
duration: A 32-bit integer that indicates how long each frame lasts in
real time." This implies that only one of the two files can be
spec-compliant. I am not a mov/ISOBMFF expert, but it seems to me that
the current way of doing things is wrong. But I wonder about whether
your patch is correct for vfr content. Doesn't the property of being vfr
need to be reflected in the timecodes somehow (with different durations
for different packets)?

Sorry, I think I have said both current and new file is spec-compliant in the
last
email.
By Quicktime file format specs:
Section Timecode Sample Description, all tmcd field isn't used pts/dts.
As for where is the different for one byte, it's caused by pkt->duration. The
old is 0(uninitialized), after the patch it's 33(1 frame duration).

You have not really answered whether the current files or the new files
are spec-incompliant; you have just reported that one byte is different.

> created with this patch be spec-incompliant?
I think both the currently created files and after are spec-compliant as the
pts/dts isn't used by tmcd track I think.
The currently code will trigger below condition as the pts/dts isn't
initialized:
[ismv @ 0x56c8c40] Application provided duration: -9223372036854775808 /
timestamp: -9223372036854775808 is out of range for mov/mp4 format
so the dts and pts will try to set them as the following code:
5640 if (pkt->dts < ref || duration >= INT_MAX) {
5641 av_log(s, AV_LOG_ERROR, "Application provided duration: %"PRId64"
/ timestamp: %"PRId64" is out of range for mov/mp4 format\n",
5642 duration, pkt->dts
5643 );
5644
5645 pkt->dts = ref + 1;
5646 pkt->pts = AV_NOPTS_VALUE;
5647 }
By the comparing hex string by before and after, one byte is different, but I
haven't figured
out where is it yet, but it's related pts and dts value.
[ffmpeg.git]$ hexdump lavf_before.ismv > lavf_before.log
[ffmpeg.git]$ hexdump lavf_after.ismv > lavf_after.log
[ffmpeg.git]$ diff lavf_before.log lavf_after.log

Are the currently created files spec-incompliant? Or will the files
created with this patch be spec-incompliant?

[FFmpeg-devel] [PATCH 1/2] avformat/movenc: initialize pts/dts/duration of timecode packet
From: Limin Wang
Fix below error message when timecode packet is written.
"Application provided duration: -9223372036854775808 / timestamp:
-9223372036854775808 is out of range for mov/mp4 format"
try to reproduce by:
ffmpeg -y -f lavfi -i color -metadata "timecode=00:00:00:00" -t 1 test.mov
Note although error message is printed, the timecode packet will be written
anyway. So
the patch 2/2 will try to change the log level to warning.
The first two test case of fate-lavf-ismv have timecode setting, so the crc of
ref data is different.
Fixes ticket #9488
