Open Caveats - Cisco IP/TV Release 3.5.7
This section lists the open caveats in Cisco IP/TV Release 3.5.7.
IP/TV Content Manager
•
Symptom: When you install IP/TV Content Manager, the installer returns the following error message:
Internal error 2755.3: Server returned unexpected error attempting to install package IP/TV Content Manager.Condition: This error occurs when the installation package is invoked from a mapped network drive.
Workaround: You can either copy the installation package to the system on which it is being installed or use the full path to the system where the installation package is stored, as shown in this example:
\\SYSTEM-Name\InstallSharedDir\CMInstaller\Setup.exe•
Symptom: The web-based program guide shows incorrect and inconsistent schedules. The web-based program guide shows different schedules for the same program when you check the guide at different times.
Condition: This problem occurs when daylight saving time is in effect and continues even after standard time resumes.
Workaround: There is no known workaround.
•
Symptom: When users try to launch the ServerWatch applet from the ServerWatch window, the applet window opens but does not show the server list, and an error message appears in the status bar.
Condition: This problem occurs whenever the ServerWatch applet is launched.
Workaround: Use the ServerWatch window instead of the ServerWatch applet to monitor the server status, number of sessions, allocated bandwidth, and total bandwidth capacity.
•
Symptom: During a software upgrade, IP/TV Content Manager settings on the disk are lost.
Condition: This problem occurs when you uninstall the existing IP/TV Content Manager manually, and then install IP/TV Content Manager in a new location.
Workaround: To preserve IP/TV Content Manager settings, install the new version in the same location as the previous version.
•
Symptom: On-demand programs disappear from the IP/TV Content Manager OnDemand Programs window when the associated media file is removed from the original location.
Condition: This problem occurs when the media file associated with an IP/TV on-demand program is removed from the original location.
Workaround: Restore the media files on IP/TV Server. The on-demand programs reappear in the IP/TV Content Manager OnDemand Programs window when the associated media files are restored on IP/TV Server.
•
Symptom: IP/TV Content Manager sends stale program listings to IP/TV Server. IP/TV Content Manager fails to send the latest guide.tvg file to IP/TV Server.
Condition: This problem occurs when IP/TV Server polls IP/TV Content Manager for program listings.
Workaround: Refresh the program listings in IP/TV Server a few times to obtain the latest program listings from IP/TV Content Manager.
•
Symptom: IP/TV Content Manager lists capture-card options that are unavailable for a program in the Select Capture Card drop-down list.
Condition: This problem occurs for audio-only programs.
Workaround: There is no known workaround.
IP/TV Plug-In
•
Symptom: The helper application does not play in IP/TV Content Manager that is operating on a Windows XP device. Clicking the Load helper application button in the Review Program window of IP/TV Content Manager opens the browser window for the helper application. However, if you click the Start the Viewer link in the helper application browser window, nothing happens.
Condition: This problem occurs when IP/TV Content Manager uses Windows XP.
Workaround: Right-click the Start the Viewer link, and save the program as an .ipt file. After the program download is completed, open the .ipt file.
•
Symptom: The IP/TV plug-in does not function when Silent Install mode is used to install the software.
Condition: This problem occurs when required files are not copied over to the Plugins folder of the browser. When the installation package runs in Silent Install mode, it fails to find the path where the browser is installed.
Workaround: Copy the following files from the [ProgramFilesFolder] \default\plugins folder from the installation package to the Plugins folder of the browser.

•
Symptom: The IP/TV plug-in does not play SlideCast streams from an on-demand program containing SlideCast as well as audio and video streams. The IP/TV plug-in plays only audio and video streams, whereas the QuickTime plug-in plays both SlideCast and video on top of each other in a single window.
Condition: This problem occurs with on-demand programs based on Real-Time Transfer Protocol (RTP) files that contain SlideCast as well as audio and video streams.
Workaround: There is no known workaround.
•
Symptom: Audio for the SlideCast stream is lost when you play a scheduled program containing live SlideCast as well as audio and video (live or file-based) streams using the IP/TV plug-in.
Condition: This problem occurs when the audio and video streams are rendered before the SlideCast stream.
Workaround: Restore the audio for the SlideCast stream by activating the SlideCast window. Use the audio control buttons to activate the window.
IP/TV Server
•
Symptom: A large MP4 file created by recording a live ISO MPEG-4 stream does not play in Windows Media Player or IP/TV Viewer. The device returns an error message, saying that the file format is invalid.
Condition: This problem occurs when a 2-GB or larger MP4 file is created from an ISO MPEG-4 stream.
Workaround: There is no known workaround.
•
Symptom: When an ISO MPEG-4 stream is set to be captured with Common Intermediate Format (CIF) resolution and a frame rate of 30 frames per second (fps), the actual frame rate may fluctuate between 20 and 22 fps.
Condition: The problem occurs when IP/TV Server operates as a Windows service on a device that has the Network Associates VirusScan program installed.
Workaround: Disable the VirusScan program (Start > Programs > Administrative tools > Services > McShield), or use IP/TV Server as an application.
•
Symptom: An error message appears when you try to play back MP4 files using the QuickTime plug-in.
Condition: This problem occurs only when you use the QuickTime plug-in to play MP4 files locally.
Workaround: Use Windows Media Player to play MP4 files. The IP/TV Server package contains a plug-in that enables Windows Media Player to read MP4 files recorded by IP/TV.
•
Symptom: Audio and video are noncontinuous and out of sync with each other in higher-frequency linear audio in Microsoft MPEG-4 and H.261 streams.
Condition: This problem occurs in programs with audio frequencies of 22 kHz and 44 kHz. For an audio-only program, this problem occurs at 44 kHz linear frequency.
Workaround: Choose one of the three MP3 audio formats (MP3, 8000 Hz Mono; MP3, 11025 Hz Stereo; or MP3, 22050 Hz Stereo) from the New Scheduled Program window or Edit Scheduled Program window of IP/TV Content Manager.
•
Symptom: An .rtp file-based IP/TV scheduled program fails to play, generating an "invalid password" error in the IP/TV Server error log.
Condition: This problem occurs in scheduled programs that are created by recording a password-protected live program to an .rtp file.
Workaround: There is no known workaround.
•
Symptom: File transfers fail when going from an IP/TV Broadcast Server to an IP/TV Archive Server.
Condition: This problem occurs when you set up a file transfer from an IP/TV Broadcast Server that is installed outside of a firewall to an IP/TV Archive Server that is situated inside the firewall.
Workaround: There is no known workaround.
•
Symptom: Video of a program using MPEG-1 appears scrambled.
Condition: This problem occurs when you have an MPEG-2 program that is also streaming from the IP/TV Broadcast Server that is streaming the MPEG-1 stream.
Workaround: Edit the iptv.ini file to increase the values for Bufs and SizeBufs variables of [VidMPEGProp] property. Increase the value of Bufs to 1500 and the value of SizeBufs to 5000.
•
Symptom: For a SlideCast program, the SlideCast server (IP/TV Server configured for slide capture) attempts to launch a video capture session and fails. IP/TV Server launches an error message in the IP/TV event log, saying that the capture card was not found.
Condition: This problem occurs for programs that contain SlideCast and live-capture streams.
Workaround: Restart the SlideCast server.
•
Symptom: IP/TV Server fails to launch a program when the program bandwidth is greater than 5700 kbps.
Condition: This problem occurs when you set the bandwidth to more than 5700 kbps for a program that is based on live MPEG-1 video and MPEG audio.
Workaround: There is no known workaround.
IP/TV Viewer
•
Symptom: Web Presenter programs that are created by using PowerPoint 2000 do not play in IP/TV Viewer. Web Presenter HTML does not work with PowerPoint 2000.
Condition: This problem occurs when the slides in the Web Presenter programs are created using PowerPoint 2000.
Workaround: PowerPoint 2000 is backward-compatible with earlier versions for creating slides that work properly with IP/TV Web Presenter. Therefore, use the backward-compatibility feature to save slides for Web Presenter programs to an earlier version of PowerPoint. Alternatively, use the ScreenCaster feature of IP/TV Web Presenter to capture the JPEG files for the presentation.
•
Symptom: The Help > About Windows Media Technologies link does not work properly. It returns a Document Not Found error page or takes you to the IP/TV 3400 Series Server page of the Cisco.com website.
Condition: This problem occurs when you access IP/TV Viewer help.
Workaround: There is no known workaround.
•
Symptom: When the program information of a program that is already playing is modified in IP/TV Content Manager, IP/TV Viewer opens an additional window to play the program.
Condition: This problem occurs on IP/TV Viewer when both IP/TV Server and IP/TV Viewer are installed on the same device.
Workaround: There is no known workaround. However, we recommend that you install IP/TV Viewer and IP/TV Server on different devices.
•
Symptom: When you change the display resolution settings, the program stops playing, and IP/TV Viewer stops responding.
Condition: This problem occurs when IP/TV Viewer operates on Microsoft Windows XP.
Workaround: Disable the DirectDraw and Direct 3D acceleration settings at Start > Settings > Control Panel > Display > Advanced > Troubleshooting.
Alternatively, follow these steps:
–
–
–
•
Symptom: The display disappears or video freezes when you switch between two IP/TV Viewer windows playing simultaneously.
Condition: This problem occurs when the UseDSoundRenderer=1 setting is disabled in the iptv.ini file.
Workaround: Enable the UseDSoundRenderer=1 setting in the iptv.ini file.
•
Symptom: MPEG-2 live video jitters on IP/TV Viewer. The jitter is quite obvious when the bandwidth of the program is increased.
Condition: This problem occurs when the Windows NT Server does not meet the minimum hardware requirements needed for IP/TV Viewer.
Workaround: There is no known workaround. However, this problem does not occur on devices that satisfy the minimum hardware requirements that are recommended for IP/TV Viewer.
•
Symptom: When you watch two IP/TV programs simultaneously, video is lost for one window when you switch to the other.
Condition: This problem occurs on a device that uses Windows XP.
Workaround: To fix this problem, disable the DirectDraw setting on the Hardware acceleration slider bar. Access the slider bar from Start > Settings > Control Panel > Display > Settings > Advanced > Troubleshooting.
•
Symptom: The video of an IP/TV program is unclear and pixelated.
Condition: This problem occurs when you play a program based on the Microsoft MPEG-4 or Video for Windows codec.
Workaround: Use ISO MPEG-4 video instead of Microsoft MPEG-4.
•
Symptom: The video fails when you try to view a program in full-screen mode.
Condition: This problem occurs when the following types of programs are played on a Windows 2000 Server PC with DirectX Version 8.1 installed:
–
–
Workaround: There is no known workaround.
•
Symptom: A SlideCast program using a native PowerPoint presentation does not play in IP/TV Viewer.
Condition: When you use a native PowerPoint presentation for SlideCast, the slides do not reach the temporary Internet files folder of the PC that runs IP/TV Viewer. The IP/TV Viewer error log shows a "file not found" error.
Workaround: Use ScreenCaster instead of SlideCast.
•
Symptom: The audio does not switch between on-demand and scheduled programs.
Condition: When an MP2T-scheduled program and an on-demand program are played concurrently, the audio does not switch between the programs when the windows are made active on an alternating basis. The audio plays correctly with two simultaneous on-demand programs. However, with an on-demand program and a scheduled program, the audio does not start in the on-demand program even when the scheduled program is closed. This problem occurs on IP/TV Viewer that uses Microsoft Windows 98.
Workaround: To restart the audio of the on-demand program, close and reopen the program.
•
Symptom: An .sdf file that is created by copying an on-demand program is not reflected in the IP/TV Viewer program listings.
Condition: This problem occurs when you add an .sdf file to the program listings by using the From File option instead of using the IP/TV Content Manager that is configured in IP/TV Viewer. However, this problem occurs only with .sdf files that are created by copying on-demand programs.
Workaround: Remove the IP/TV Content Manager that is configured in IP/TV Viewer and then specify the filename by using the From File option in the Content Managers dialog box (accessed by choosing Settings > Content Managers in the IP/TV Viewer Program Listings window).
•
Symptom: Certain versions of .asf files do not play properly on IP/TV. Video does not play in some cases, while audio plays with a stutter. When video fails, IP/TV returns an error message saying that the required compressor is not available.
Condition: This problem occurs with .asf files later than Version 3. IP/TV supports Windows Media audio up to Version 8 but supports only up to Version 3 for Windows Media video.
Workaround: Avoid using Windows Media codecs later than Version 3.
Resolved Caveats - Cisco IP/TV Release 3.5.7
This section lists the resolved caveats in IP/TV Release 3.5.7.
IP/TV Server
•
CPU usage reaches a level of 90 to 95 percent when four CIF streams of ISO MPEG-4 with MP3 audio are streamed from IP/TV 3427 Broadcast Server models. This problem occurs when IP/TV Broadcast Server operates as a Windows service.
•
An ISO MPEG-4 program using MP4 22-KHz audio sometimes shows a drop in frame rate when the program streams for a long duration.
•
Video appears distorted and unclear for programs that use Microsoft MPEG-4 video.
•
Video that contains fast movements appears distorted and lacks clarity. This problem occurs for programs that use ISO MPEG-4 video with MP3 22-KHz audio.
IP/TV StreamWatch
•
IP/TV StreamWatch does not save user information for an IP/TV scheduled program that has repeat broadcasts scheduled. When you choose Monitor and Log option for a scheduled program with repeat broadcasts, IP/TV StreamWatch updates the information about the clients in the Status window, but does not save the information to the database.
IP/TV Viewer
•
Web Presenter stream from an .mp4 file-based program fails to play. However, audio and video streams of the program play properly.
•
IP/TV StreamWatch does not show client information for IP/TV Viewer clients that are configured for unicast Real-Time Transport Control Protocol (RTCP) feedback.
•
IP/TV Viewer fails to update the IP/TV Content Manager address from the iptv.ini file when users use the Silent Install option for multiple users. This problem occurs when Silent Install mode is used after the iptv.ini file has been edited to configure a new IP/TV Content Manager address. However, this problem does not affect the user who actually performs the installation by using the Silent Install mode.
