Greetings,
I'm wondering if anyone would be able to create an import filter that allows VirtualDub to open 'DASH' format.
DASH is a format that YouTUBE uses to stream 720p and 1080p by separating both the audio and video streams. There is a Firefox plugin: Youtube Video and Audio Downloader, which allows you to download these streams and it would be great if we could add the audio / video tracks directly into VirtualDub.
Even though the files are AVC/H.264 and AAC, the major_brand is 'DASH' so VirtualDub doesn't recognize it. In order to be able to edit the video, you have to first mux it with ffmpeg.
Here's some output from Mediainfo:
| CODE | Format : dash Codec ID : dash File size : 44.6 MiB Duration : 4mn 32s Overall bit rate : 1 375 Kbps
Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : Main@L3.1 Format settings, CABAC : Yes Format settings, ReFrames : 3 frames Codec ID : avc1 Codec ID/Info : Advanced Video Coding
|
| CODE | Format : dash Codec ID : dash File size : 8.27 MiB Duration : 4mn 32s Overall bit rate mode : Constant Overall bit rate : 255 Kbps
Audio ID : 1 Format : AAC Format/Info : Advanced Audio Codec Format profile : LC Codec ID : 40
|
Thanks! |

Very doubtful that someone would bother, when there are loads of things that can download files from youtube as mp4, flv etc that load using existing plugins
I use JDownloader as a general file downloader, and that also lets you download from youtube in all formats/resolutions http://board.jdownloader.org/showthread.php?t=54725 Just copy the url and it gives you a list of available files There are plenty of others as well, including firefox plugins or greasemonkey scripts that will do it but jdownloader does what I need so I'm not testing everything else :-)

Anything that downloads as 1080p must mux the two streams since they are separate. The plugin I linked does that using ffmpeg but only if you use the default Firefox downloader.
I use DownThemAll so I can control speed and not choke my connection and the plugin integrates with it but it will not mux the streams afterward, I have to do it manually. I just thought it would be nice to be able to batch it all in VirtualDub where I can apply other filters and trim off ESRB notices and other junk. |

<Shrug> jdownloader just does it all for me (muxing, speed limiting etc) so that's not a problem
A plugin for virtualdub would be a lot of work to replicate what's already out there or could be done with little effort Unless a coder decided it'd be a nice side project or something they want themself, I can't really see it happening

The FFMpeg Input Plugin can already open dash files (they are a variation of the MP4 container).
