I am uploading to the server now:

Ticket #2398.wtv (sample to repeat problem)
Ticket #2398.txt (req text file related to this case)
Ticket #2398.log (same log file as attached)

FYI after conversion, you will need to seek to around 4m:40s for the skipping to become apparent.

Ticket #2398.wtv failed to upload to server, for some reason after a while my connection disconnects from the ftp.

The new file will be here: http://www.4shared.com/folder/fx0nRHmq/mediastuff.html once complete.

It is completely unacceptable to upload a sample to a site that requires login.

comment:4 follow-up: Changed 4 years ago by dodgexander

It is completely unacceptable to upload a sample to a site that requires login.

Sorry I didn't realise it needed a login!

I tried:

Your ftp server (connection broke)
Mediafire (200mb limit)
Datafilehost (100mb limit)

Any suggestions where I can upload it? If you sign up for free on 4shared you can download it, would save me a lot of time. Otherwise Ill upload elsewhere.

Replying to dodgexander:

I tried:

Your ftp server (connection broke)

While this will not help you I'd still like to add that last month a 11G sample was uploaded (successfully) to our ftp server.

I expect it was, but perhaps not from a rural adsl 1 connection with the reliability of *.

I can try again I guess.

Ticket 2398.wtv is available on the ftp server.
Please don't get mixed up with the file: Ticket #2398.wtv which is a failed upload.

  • Keywords wtv h264 dts added
  • Reproduced by developer set
  • Status changed from new to open
  • Summary changed from Copy Encoder Produces Broken Output to Bad timestamps for h264 wtv
  • Version changed from unspecified to git-master

Sample uploaded to http://samples.ffmpeg.org/ffmpeg-bugs/trac/ticket2398/

The input sample plays fine with WMP, if video gets remuxed with FFmpeg, the resulting file plays with visible stutter in WMP, this (probably) corresponds to the "invalid pts, clipping" messages. Reproducible both with and without audio.

Maybe a duplicate of ticket #2233.

comment:10 Changed 3 years ago by michael

  • Summary changed from Bad timestamps for h264 wtv to Bad timestamps when remuxing h264 wtv to ts

comment:11 Changed 3 years ago by cehoyos

Remuxing the video to mov and avi produces identical (or at least very similar) problems on playback with vanilla WMP.

comment:12 Changed 3 years ago by cehoyos

Also reproducible when remuxing to asf:
$ ffmpeg -i Ticket\ 2398.wtv -vcodec copy -ac 2 out.asf

comment:13 Changed 3 years ago by dodgexander

Any info on this problem? What happens next?

comment:14 Changed 3 years ago by ramitbhalla

Anyone any insight into this?
