  • Known problems with video streaming

    There are some known problems with QuickTime video streaming, some of which I don't understand. Generally, it works, and it works well. Some important issues, however, that you should keep in mind.
    • If you are behind a firewall, you will need to open port 554 and or 7070. Some personal firewalls can be adjusted to open for QuickTime streaming (they open port 554) via software and web browser. If you are behind a corporate firewall, you'll need to have your network administrator open up that port.
    • There is an option in QuickTime player, under Preferences / Registration, that is called "Streaming Transport". We do not stream these videos on port 80; therefore, if the port 80 box is checked, it will not work. Make sure that port 554 is checked. If you use the AutoConfigure button to automatically check for a firewall, and "suggest" a setting, you might get the wrong information. Unfortunately, if you are behind a firewall, the AutoConfigure button will suggest port 80, which, will not work, as we are not streaming the video on port 80. You need to have this set on port 554, and have your network administrator open that port in the firewall.
    • As far as connection speeds go, (Again, Edit/Preferences/Registration/Connection /Speed), we are streaming, preferably, at 256 kpbs DSL/Cable. It is best that you set your QuickTime player to that setting, if you are on a DSL or Cable line. If you are on a 56kbps dial up modem, set your connection speed to that. But, chances are, even though we have optimized these videos to stream under most conditions, a 56kpbs modem might not be fast enough. A fast internet connection is important.
    • Sometimes you will notice that the QuickTime video box will open, with it's controls, but that nothing happens when you click the "Play" arrow button. Sometimes only audio will be heard, without any video. There are a few things that you can try if this occurs. First, refresh your browser page, and allow the QuickTime Player to reload, then try clicking the "start" arrow again. If this does not work, try letting the player download the entire file; ie, allow it to play, even though you don't see anything. Once the player has played the entire file, ie, QuickTime has cached the entire file, try rewinding it and playing it again. If you are still unsuccessful, come back and try again later. The server might be overloaded with requests, or, the gods of the internet might not be happy at that time.
    • Try using a computer that has a faster video card, or a computer that has a video card with more ram memory. Laptops tend to be more unreliable than desktops when it comes to receiving streamed media.
    • These files work, as they have all underwent extensive preparation and testing, but they are subject to all the various nuances and difficulties found on the internet. If you are unsuccessful in viewing any of these, please be patient and try again.


    We hope you enjoy them. There are many, many more currently being edited, produced, converted, and tested, prior to their release on this forum.

    Video Streaming issues

    We are fully aware of the fact that the streaming videos do not work well if you do not have a high speed broadband internet connection. We have used the most modern compression technology available, but, when we formatted the videos for streaming, we formatted them to stream at 256kbps.

    We now know that we can have multiple formats, for those of you who are on lower speed connections, such as 112k or 56k. We are in the process of reformatting the current videos, and will be formatting the future videos, so that people with slower connections might benefit. As this will take some work to do, we don't expect to have the slower speed videos available in the Video Library for the next few weeks, at least not until I get back from Shaolin. Hopefully, more people will benefit from these changes in the future.

    Remember to read all the announcements and the technical support threads concerning the QuickTime streaming. Also make sure that you have your QuickTime player set according to your appropriate connection speed.

    There are a lot more videos on the way; not only the ones that are currently being produced, edited and formatted for streaming, but the ones I'm going to be shooting on this current trip. Please be patient; we're getting this together.

      Some other QuickTime issues

      When trying to stream the videos, make sure that your QuickTime Player settings are set properly. Open your QuickTime player, click on EDIT, PREFERENCES, QUICKTIME PREFERENCES. Then, in the drop down list, choose STREAMING TRANSPORT. Make sure that you set it to "Use this protocol and port ID" to "Use UDP RTSP Port ID 554".

      We stream on port 554. Also, if you are behind a firewall, make sure that your firewall is open for port 554. Also make sure that you have the latest upgraded version of Apple QuickTime.
