Note
Open Caveats in IP/TV Release 5.2.5
This section lists the open caveats in Cisco IP/TV Release 5.2.5.
IP/TV Server
•
Symptom: A large MP4 file that is created by recording a live ISO MPEG-4 stream does not play in the 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: Audio and video are noncontinuous and not synchronized 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: You can 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 Program Manager.
•
Symptom: When you play a live program with an ISO MPEG-4 stream in IP/TV Viewer, the video appears distorted.
Condition: This problem occurs only if the resolution for the ISO MPEG-4 video is customized.
Workaround: For ISO MPEG-4 video, use only the resolutions available in the Predefined drop-down list in the Multimedia Source Information section of the New Scheduled Program window. Avoid changing the resolution settings for ISO MPEG-4 video.
•
Symptom: It takes too much time to export RTP files when you use the Media File Exporter utility.
Condition: This problem occurs when you export an RTP file to MOV format by using the Media File Exporter utility.
Workaround: There is no known workaround.
•
Symptom: A live program shows a drop in frame rate when the bandwidth settings are changed in IP/TV Program Manager.
Condition: This problem occurs when you change the bandwidth settings of an existing live program.
Workaround: To change the bandwidth settings of a live program, re-create the program with the desired bandwidth.
•
Symptom: IP/TV Broadcast Server stops functioning when it receives a request for the same on-demand program from two IP/TV Viewers.
Condition: This problem occurs when two IP/TV Viewers request an .mpg file-based on-demand program that contains an MP2T stream.
Workaround: When recording an MP2T stream, use MOV recording instead of using MPG or MP4 recording.
•
Symptom: You are unable to preview a live MPEG-4 program on the server by using Program Details > Video > Show Preview.
Condition: This problem occurs with a scheduled program that is an ISO MPEG-4 video with the frame size set to 352 x 288 and AAC 16-kHz stereo audio.
Workaround: There is no known workaround.
•
Symptom: Certain pre-positioned MP4 files cannot be played back when streamed by the Cisco Streaming Engine.
Condition: This problem occurs when you stream nonhinted MP4 files over the Cisco Streaming Engine. (Hint tracks contain packetization information that tells the streaming server how to package the media data. The streaming server uses the packetization information in the hint tracks to stream the media data to the network. Nonhinted files do not have hint tracks.)
Workaround: Use only hinted MP4 files for steaming over the Cisco Streaming Engine.
•
Symptom: IP/TV Broadcast Server shuts down abruptly during startup or takes too long to display program listings.
Condition: This problem occurs when the IPTVMedia folder has more than one hundred nonmedia files.
Workaround: Add the types of nonmedia files in the IPTVMedia folder to the Invalid File Types section of the iptvserv.ini file, and then restart IP/TV Broadcast Server.
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 by 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: IP/TV Viewer becomes unresponsive when the display resolution settings are changed.
Condition: This problem occurs on IP/TV Viewer that uses Microsoft Windows XP.
Workaround: Stop and exit any program that is being played by IP/TV Viewer before changing the display settings.
•
Symptom: The display disappears or video freezes when you switch between two IP/TV Viewer windows that are 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 increases.
Condition: This problem occurs when the Windows NT Server does not meet the minimum hardware requirements that are 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 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: A live-capture program that uses Video for Windows (VFW) and AAC audio appears blurred in the IP/TV Viewer window.
Condition: This problem occurs only when you use the Video for Windows and AAC audio combination for live capture.
Workaround: Use MPEG-4 video when you are using AAC audio for live capture.
•
Symptom: The audio on IP/TV Viewer has echoes when you play a program that uses AAC audio.
Condition: This problem occurs when you play a program that uses AAC audio. However, this problem is less severe for programs that use AAC, 44,100-Hz audio.
Workaround: Use MP3 audio instead of AAC audio.
•
Symptom: IP/TV Viewer stops responding when you start a program that contains Microsoft MPEG-4 video.
Condition: This problem occurs when the mpeg4mod.dll file is missing from the device on which IP/TV Viewer is installed.
Workaround: Copy the mpeg4mod.dll file to the system32 folder of the device. (The mpeg4mod.dll file comes with Windows Media Player and is a filter for Microsoft MPEG-4.) Alternatively, install Windows Media Player Version 7.1.x or later on your device.
•
Symptom: Video of a program that uses MPEG-1 appears scrambled.
Condition: This problem occurs when you have an MPEG-2 program also streaming from the IP/TV Broadcast Server that is streaming the MPEG-1 stream.
Workaround: Edit iptv.ini file and modify the values of the Bufs and SizeBufs parameters of [VidMPEGProp] property. Set the value of Bufs to 1500 and that of SizeBufs to 5000.
•
Symptom: When you play an on-demand program in IP/TV Viewer, you experience breaks in audio and video playback.
Condition: This problem occurs when you perform consecutive jump operations, forward or backward, for an on-demand program by using the VCR controls in the IP/TV Viewer on-demand program window.
Workaround: Use the Position Control slider bar for video positioning. If the problem persists, pause and restart the playback.
•
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 alternate 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: Restart the audio of the on-demand program by closing and reopening the program.
•
Symptom: Certain versions of .asf files do not play properly on IP/TV. Video does not play in some cases, while the audio plays with a stutter. For video failure, 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, whereas for Windows Media video it supports only up to Version 3.
Workaround: Avoid using Windows Media codecs later than Version 3.
•
Symptom: IP/TV ScreenCaster displays a black screen that contains dark images of the desktop windows and closes down abruptly.
Condition: This problem occurs when the display color settings of the device are set to 256 colors.
Workaround: Change the color settings of your device to 32-bit true color. To change the color settings, choose Start > Settings > Control Panel > Display > Settings > Colors.
•
Symptom: Live MPEG-4 video lacks clarity and appears distorted.
Condition: This problem occurs only for live programs encoded using Microsoft MPEG-4.
Workaround: Use ISO MPEG-4 encoding instead of Microsoft MPEG-4.
•
Symptom: IP/TV Viewer becomes unresponsive or generates errors and shuts down when it plays a scheduled program associated with an IP/TV channel.
Condition: This problem occurs if the password setting of the associated channel is modified while the program is playing.
Workaround: Avoid modifying the password setting of an IP/TV channel less than 10 minutes before a program is scheduled to begin or while a program is playing. Alternatively, stop or disable the programs that are associated with the channel, and then modify the channel settings.
•
Symptom: IP/TV Viewer switches the windows for SlideCast and video; that is, the SlideCast window contains video, and the video window contains SlideCast.
Condition: This problem occurs when both of the following conditions are true:
–
–
Workaround: There is no known workaround.
•
Symptom: When a password-protected NetShow on-demand program launches from an on-demand playlist, the program plays even if the password is not provided. The program continues to repeat many times until you close the password dialog box by either entering the correct password or clicking the Cancel button.
Condition: This problem occurs only when the NetShow on-demand program is launched from the on-demand playlist. This problem does not happen if the NetShow on-demand program launches as the first program of the on-demand playlist.
Workaround: There is no known workaround.
Resolved Caveats in IP/TV Release 5.2.5
This section lists the resolved caveats in IP/TV Release 5.2.5.
IP/TV Server
•
CPU usage reaches a level of 90 to 95 percent when four CIF streams of ISO MPEG-4 with MP3 audio stream from IP/TV 3427 Broadcast Server models. This problem occurs when IP/TV Broadcast Server operates as a Windows service.
•
Audio and video do not synchronize for live programs that use Microsoft MPEG-4 video and MP3 22050-Hz stereo. This problem occurs when the live programs stream for a long duration (5 hours or more).
•
When you stream an ISO MPEG-4 program that uses MP3 22-KHz audio for a long time, the program shows a drop in frame rate.
•
Mapping of Multicast IP address and track IDs in .prg file is incorrect for some programs that use .mov or .mp4 files that have track IDs in an incorrect order.
•
Video appears distorted and unclear for programs that use Microsoft MPEG-4 video.
•
When you stream an IP/TV program, which contains ISO MPEG-4 video and MP3, 22-KHz audio, for more than 15 hours, the program stops abruptly.
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.
•
Audio and video of an .mp4 file-based program go out of synchronization. This problem occurs when you play an .mp4 file-based program that contains ISO MPEG-4 video and MP3, 22-KHz audio.
•
When you play an on-demand program that uses a .mov file, video does not play in IP/TV Viewer. This problem occurs when the program uses a .mov file that is created from an.mp4 file by using the media exporter utility of IP/TV Broadcast Server.
•
IP/TV Viewer fails to update the IP/TV Program 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 Program Manager address. However, this problem does not affect the user who actually performs the installation using the Silent Install mode.
•
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.
•
Symptom: Audio and video go out of synchronization for programs that use MPEG-1 video and MPEG audio. This problem occurs when you stream the program continuously for more than 48 hours.
