Marc Pierson Message Info Reads: 46890 Responses: 0 Posted: 5/14/03; 1:16:57 PM  We will use this space to chronicle the development of a stable process for creating streaming content for weblogs stories. Today Christine Kelly, Rachael Lucy, and Marc Pierson met to develop a plan. We created a high level flow chart and generated several tasks. Christine will begin making digital audio files and will FTP them to the server (with Jack's guidance). Jack will work out the FTP routine and hopefully find icons that will indicate audio and video content in our weblogs. Jeff Blomquist, Jack, and I worked out some issues about the relation of the server to the firewall. So we should have the server on-line soon. How is this for a start?

Mancilla Message Info Reads: 46919 Responses: 0 Posted: 5/14/03; 6:39:54 PM  Pretty amazing. Soon. ... I expect to see the server (over the net) tomorrow. Then I will check out the serving with some test files. Remember that we are working with QuickTime movie files. ... Whatever video we are working with, the end result will be a streaming quicktime movie. ... Just something to keep in mind while you are looking around.

Now she will be able to encode .WAV files as QuickTime .MOV files and stream them from the QuickTime server. I also gave her software and hardware for transcription of digital files--WavePedal is the name of the package. It works great. Small but quick steps.

Marc and I have a couple movies up there that need to be viewed with QuicktimePlayer right now. ... Marc's movie should be able to be viewed in your Quicktime player if you start your player and then in the file menu, choose "Open Url." Here are a couple URLs to try. You cannot click on these URLs, they need to be opened in your QuickTime Player. You could try both these (With and without the port number.) <rtsp://170.96.240.28:80/marcpierson2/escapeFire.mov> <rtsp://170.96.240.28/marcpierson2/escapeFire.mov> You could try both these (With and without the port number.) <rtsp://170.96.240.28:80/ijak/front1.mov> <rtsp://170.96.240.28/ijak/front1.mov> Movies need to be "Hinted" in order for the server to serve them. "Hinted" is just a name and a verb, that means that the audio and video tracks of the movie get looked at and then annotated so that the server knows how to serve the movie to the various clients that will view the movies. The "Hinted" audio and video tracks then become additional tracks in the movie. Right now we are having a little problem, in that some people need to have a port number in the URL in order to view the movie.

BE SURE TO USE QUICKTIME 6 as it has many important features that we intend to use. For folks on the implementation team: If you are behind a firewall that blocks downloading this application and  and are on the P2 project ask you desk top rep to install it. Good luck. We are learning. Give Jack lots of constructive feedback as we get this going. If you have problems talk with Marc Pierson or Lori Nichols.

Jack F. Mancilla Message Info Reads: 46959 Responses: 0 Posted: 5/17/03; 8:40:13 AM  This is a blank spot. ... But it does represent a stream that is waiting to be played. It is the same as the automatic stream except for the fact that this stream waits for the client to say, "Play." We are having some problems with the streaming. I have submitted a report to Apple. This is a link to the story that documents some of this problem. <http://www.wwpp.org/users/0000028/stories/2003/05/21/windows2000ProblemWithQuic.html> Marc Pierson Message Info Reads: 46619 Responses: 0 Posted: 5/21/03; 6:31:46 AM  Jack, The above .mov begins streaming when the page is opened. In a discussion page I think that it should be set to require the user to "press" play. Can you do that.  Inside the firewall the quality is still poor but it does play. One suggestion on the quality: is that a way on the server or on the PC to tell it to accumulate a significant portion of the stream before beginning to play? Marc Pierson Message Info Reads: 46784 Responses: 0 Posted: 5/21/03; 6:34:30 AM  Jack, can we give the end user the option of downloading the whole file OR choosing streaming? I hope so. If so why not try to set one of those choice scenerios up in this discussion. Please turn off the auto stream on page loading on your end or tell the user how to do it here. I will look for local controls on QT. BUT nice work getting it to STREAM INTO THE WEB PAGE. Jack F. Mancilla Message Info Reads: 46939 Responses: 0 Posted: 5/21/03; 7:40:29 AM  The stream is automatic. There is no way to accumulate a larger portion of the stream, like increase a buffer size. ... We can give the user the choice to view the stream, or to download the entire movie. We can also place progressive movies on the site that do accumulate some of the movie before the movie starts to play. Marc Pierson Message Info Reads: 46681 Responses: 0 Posted: 5/21/03; 4:56:13 PM  Please make it happen that we test the progressive streaming as well as the full download prior to playing. Thanks Jack Lori Nichols Message Info Reads: 46736 Responses: 0 Posted: 5/23/03; 12:55:21 PM  Try try again.  On opening the discussion page I got an "error with a plug in  on the page" message.  Tried to run rtsp://170.96.240.28/ijak/front1.mov in Quick time...  Got a "10061 connection failed" message. Clicked on the Watch Now button under Jack's picture and got the following: Couldn't open the file, because a necessary data reference could not be resolved. Tried to update QuickTime and got an error message saying the updater wasn't a valid Win32 application: Marc Pierson Message Info Reads: 46706 Responses: 0 Posted: 5/23/03; 2:32:14 PM  Lori, can your desk top guy trouble shoot the last, non-valid Win32 application? Jack is working with Jon Lussier on the others: from Jack to Jon-- Jon, Are you sure we are not behind some kind of firewall? I have been fighting a problem with streaming over port 80. ... Today, I did a port scan from here in San Diego of the X-Server I did a port scan from San Francisco, and I did a port scan from the Manila server in Bellingham. And I did a port scan from the X-server. The X-server says that the port is open. Everything else says that the port is closed. So we are losing the ability to stream over port 80 somewhere between the x-serve and the rest of the world. Jack Jack F. Mancilla Message Info Reads: 46736 Responses: 0 Posted: 5/24/03; 10:56:34 AM  Something happened yesterday (Friday), and I now have access to port 80 from the wwpp Quicktime server and the wwpp manila server, but nowhere else. Here is a page of images that illustrate the port scans and the access attempts. <http://www.wwpp.org/users/0000028/stories/2003/05/24/port80ProblemsOutsideWwppL.html> Marc Pierson Message Info Reads: 46945 Responses: 0 Posted: 5/28/03; 6:45:27 AM  Jack, could you place here the current thinking on the barriers to seeing streaming content inside PeaceHealth and HInet AND the plans to resolve. Thanks. Jack F. Mancilla Message Info Reads: 46846 Responses: 0 Posted: 5/28/03; 9:02:03 AM  Since I am not behind a firewall. I have no way of testing which of these work. ... So a little help and a couple tests would be nice. These URLs are to be copied (without the "<" and ">" symbols)and pasted into your QuickTime player, using the QuickTime Players "Open URL" command. ... <rtsp://170.96.240.28:554/ijak/front1.mov> RTSP with Port number <rtsp://170.96.240.28/ijak/front1.mov> RTSP without Port number <http://170.96.240.28:80/media/movies/ijak/front1.mov> HTTP with Port number <http://170.96.240.28/media/movies/ijak/front1.mov> HTTP without Port Number Once I have an idea as to which works, I will take the next step. P.S. You may need to check your preferences in the QuickTime Player. This is a story to help you check that you have the correct protocall setup in your player. ..
