Why might ffprobe -show_format disagree with -show_data duration ?
2 juillet 2014, par Felix FungFor the purposes for re-encoding a video, I am probing an mp4 (h264/aac) file. I’m wondering why there a discrepancy between the video [STREAM]’s reported duration
duration=6.500000
(while the audio’s duration is 6.54, the video’s duration should be the target) and the duration in provided by the -show_data and -show_format optionsduration=6.466667
may occur as seen in the following output.~/workspace/ (master):ffprobe -show_format -show_streams -show_data -of json original.mp4

Piwik is now using Github issues as our Issue Tracker !
9 juillet 2014, par Matthieu Aubry — Community, DevelopmentThis is an announcement regarding the Issue Tracker used for the Piwik project. We are excited to announce that Piwik has migrated from Trac to now using Github issues for managing our issues !
More than 5,400 tickets and 20,000+ comments from 1,000+ users were migrated to Github. Read on for more information.
Where do I find Piwik Issue Tracker ?
- Piwik main project issue tracker (piwik/piwik)
- Piwik Mobile issues (piwik/mobile2)
- Device Detector issues (piwik/device-detector)
- Piwik iOS SDK (piwik/piwik-sdk-ios)
- See other repositories at github.com/piwik
Benefits of using Github Issues for the Piwik project
There are several advantages of moving to Github issues :
- Faster and responsive user interface
- Better cross-project referencing of issues
- Ability to notify people with the @username functionality
- No spam
- Integration with Pull requests and our Git repository
How do I get notifications for all Piwik tickets ?
To receive notifications for new tickets or new comments in the Piwik project, go to github.com/piwik/piwik, then click the Watch button at the top of the page.
In Github, watching a repository lets you follow new commits, pull requests, and issues that are created.
How do I report a bug in Piwik ?
See Submitting a bug report.How do I suggest a new feature ?
See Submitting a feature request.Next steps
At Piwik we care a lot about Data ownership. For this reason we need to have an up to date copy of all our tickets and comments out of github.com servers. Our next step will be to create and release as open source a tool to let anyone create a Mirror of their Github issues. See #5299.
For more information about the Trac->migration, see #5273.
We look forward to reading your issues on Github !
