Summary

0002717: Multi-stream video should be split when clips are added

Description

For multi-stream video + audio recordings (see Additional Information section for ffmpeg stream dump) only the first video + audio stream is accessible.

http://www.youtube.com/watch?v=30oYtId7WzI [^] is a bug report issued against Camtasia related to multi-stream recordings which show how ScreenFlow (correctly) and Mac Camtasia (incorrectly) allows access to different streams.

Steps To Reproduce

Add a multi-stream clip to Kdenlive and only first video + audio stream(s) are available.

Notes
(0008265) dfavor (reporter) 2012-09-03 19:39	iMovie (correctly) allows access similar to ScreenFlow.

(0008276) j-b-m (administrator) 2012-09-05 07:34	Can't you access other streams from the clip properties > advanced tab, using the audio/video indexes? However, i agree that we could have an option when importing such clip to either ask which stream to use or to add one clip for each stream...

(0008288) j-b-m (administrator) 2012-09-07 15:12	Could you attach here a short sample of a multiple video stream file for our tests?

(0008293) j-b-m (administrator) 2012-09-08 00:20	Ok, I have found a sample clip and improved Kdenlive. Now, when you add a clip that has several video streams, a dialog pops up asking if you want to import the other streams into your project (see attached screenshot). Also, now the clip refreshes correctly if you change the audio or video index in the Clip Properties dialog (advanced tab). Before, you had to reload the clip to see the change.

(0008295) dfavor (reporter) 2012-09-08 01:38	Great!

(0008296) j-b-m (administrator) 2012-09-08 08:55	I would be interested to have your opinion on the workflow. Currently it works like this: When adding a multi stream clip in Kdenlive, it imports a clip using the first audio and the first video stream. Then, a dialog pops up asking if you want to import other streams, with a list of the other video streams. If you want the other stream, you must click in the checkbox next to the stream. The other clip is then added to the project. Does. That seem ok to you, or do you think we should have an option to automate this?
