Zipstream technology

Introduction

Zipstream is a bit rate reduction technology optimized for video surveillance that reduces the average bit rate by removing unnecessary data and makes it possible to allow higher resolutions, reduce storage cost or to keep recordings for a longer time. To reduce the bit rate, Zipstream reduces the number of bits in the areas of the image that are less interesting from a video surveillance perspective, for example the background. Image details that are important for forensic video analysis, for example faces and license plates, are preserved with enough number of bits.

Axis Zipstream technology for H.264 conforms to the H.264 standard and is compatible with third-party clients and VMS solutions that decode H.264 video. To use the Zipstream dynamic GOP mode, some clients might need to adapt their H.264 playback implementation. The fixed GOP mode works with all implementations.

Note
For more information about Zipstream, see the Zipstream technology white paper.

If the Axis product supports Axis Zipstream technology, some Zipstream elements are enabled by default and will automatically be used when a client requests an H.264 stream. Zipstream can be used together with variable bit rate control (VBR) or with maximum bit rate control (MBR).

Zipstream is affected by the compression parameter in the RTSP request axis-media/media.amp?compression=30. When Zipstream is enabled, this parameter controls the amount of compression applied to the important forensic details. That is, compression only affects the important forensic details. Compression is usually set to 30 and this value is recommended also for Zipstream streams.

Using VAPIX, the Zipstream settings can be controlled through:

  • Zipstream API – Retrieve and configure Zipstream settings such as the strength and GOP mode. These settings will be used for all streams unless overridden in an RTSP stream request. See Zipstream API.

  • RTSP API – Specify Zipstream parameters when requesting a stream. The parameters are used only for the requested stream. See Zipstream in RTSP requests.

Identification

VAPIX® Zipstream API is available if

Property

root.Properties.ZipStream.ZipStream=yes

Firmware

5.80 and later

Product category

Network cameras using ARTPEC-5 and later

Note
Firmware version 6.30 and later is required for FPS mode if root.Image.I#.MPEG.ZFpsMode exists.

Zipstream strength

Zipstream strength is a measure of the amount of bit rate savings. Increasing the strength reduces the bit rate but will also affect image quality outside the area of interest and not affect the forensic details.

By default, Axis products with Zipstream technology are configured to use strength 10 and fixed GOP mode. This setting reduces the bit rate significantly without affecting the visual image quality and is compatible with third-party clients and VMS solutions.

Zipstream strength 30 or higher (30 for cameras with firmware before firmware version 6.30) with dynamic GOP is recommended for cameras that are connected to the cloud and for cameras that record to SD cards and need to limit the bit rate in order to keep recordings for a longer time. To further optimize the use of storage, this setting can be combined with motion-triggered recording and/or maximum bit rate control (MBR).

The following table lists supported Zipstream strengths:

Zipstream strengthDescription
off

Zipstream is disabled.

10
20
30
40
50

Valid Zipstream strengths. Default value: 10

Increasing the strength reduces the bit rate but will also affect the visual image quality. At the default value 10, visual image quality is not affected, but as the strength increases, visual image quality is degraded in unprioritized image areas, for example the background. Image details important for forensic video analysis are kept.

60
70
80
90
100

Deprecated.

Zipstream GOP mode

Zipstream can be used in fixed or dynamic GOP (Group of Picture) mode. Dynamic GOP will reduce bit rate even more and is recommended if the Zipstream strength is 30 or above.

GOP modeDescription
fixed

The GOP length is fixed and set to the Axis product’s default GOP length.

dynamic

When possible, unnecessary I-frames are removed in order to further reduce the bit rate. The GOP length varies between the Axis product’s default GOP length and a configurable, maximum GOP length. The maximum GOP length is used for scenes with no or almost no motion; the default GOP length is used for busy scenes.

Dynamic GOP mode is recommended when the Zipstream strength is 30 or above.

The default GOP length is defined by parameter Image.I#.MPEG.PCount. In RTSP requests, the default GOP length can be overridden by videokeyframeinterval.

Note
Using dynamic GOP can result in long key frame intervals. Depending on the H.264 playback implementation, long key frame intervals could cause problems viewing recorded video in some clients and VMS solutions.

For more information, see the Axis Zipstream Technology white paper.

Zipstream FPS mode

There are two frame rate (fps) modes available.

Fps modeDescription
fixed

The fps will be the default one set for the stream (it may vary due to rate control limitation).

dynamic

The dynamic fps mode shall be triggered by the motion in the scene, if using Zipstream strength of 30 or above it is recommended to use dynamic fps mode.

Dynamic fps is off when Zipstream strength is set to off.

It is the user’s choice to activate/deactivate this feature independently from the other Zipstream parameters.

The fps is defined by parameter Image.I#.MPEG.ZFpsMode

Note
Some VMS might adversely affect the user experience, for example fps may reduce and the user may think the stream has frozen.

For more information, see the Axis Zipstream Technology white paper.

Zipstream minimum FPS mode

The minimum dynamic frame rate. This parameter is only relevant if Ziptream = ON and dynamic FPS = dynamic.

Minimum FPS modeDescription
00 means that the FPS is allowed to go as low as the dynamic frame rate can go. If a value is greater than 0 the dynamic frame rate is not allowed to go below the specified value.

Zipstream in RTSP requests

If the Axis product supports Zipstream technology for H.264, Zipstream is enabled by default and used in all RTSP streams. Zipstream settings, such as the strength and GOP mode, are defined by VAPIX® Zipstream API and will be used when a client requests an RTSP stream. Clients can override the Zipstream settings by including Zipstream URL parameters in the RTSP request.

RTSP video stream with Zipstream strength 20 and fixed GOP mode:
rtsp://myserver/axis-media/media.amp?videocodec=h264&resolution=1920x1080
&videozstrength=20&videozgopmode=fixed
RTSP video stream with Zipstream strength 30 and dynamic GOP mode:
rtsp://myserver/axis-media/media.amp?videocodec=h264
&videozstrength=30&videozgopmode=dynamic
RTSP video stream with dynamic Zipstream GOP mode and maximum GOP length 400:
rtsp://myserver/axis-media/media.amp?videocodec=h264
&videozgopmode=dynamic&videozmaxgoplength=400
RTSP video stream with dynamic Zipstream GOP mode, maximum GOP length 400 and minimum GOP length 32:
rtsp://myserver/axis-media/media.amp?videocodec=h264
&videozgopmode=dynamic&videozmaxgoplength=400&videokeyframeinterval=32
RTSP video stream without Zipstream (not recommended):
rtsp://myserver/axis-media/media.amp?videocodec=h264&videozstrength=off
RTSP video stream with fps mode dynamic:
rtsp://myserver/axis-media/media.amp?videozfpsmode=dynamic
RTSP video stream with videozminfps, set to 15 in this example (only when videozfpsmode is set to dynamic):
rtsp://myserver/axis-media/media.amp?videozminfps=15

The RTSP API is described in Video streaming over RTSP. Available URL parameters are listed described in Parameter specification RTSP URL.

Zipstream API

Description

VAPIX® Zipstream API is used to configure Zipstream technology. Using the API, the Axis products Zipstream settings such as the strength and GOP mode can be configured. The Zipstream settings are used for all RTSP streams but are overridden if Zipstream URL parameters are included in the RTSP request.

Supported functionality:

  • List the current Zipstream settings.

  • Set the Zipstream strength.

  • Set the Zipstream GOP mode.

  • Set the maximum Zipstream GOP length.

  • Set the Zipstream FPS mode (from firmware 6.30 and later).

Zipstream is enabled by default but can be disabled by setting the strength to off.

Get schema versions

Use zipstream/getschemaversions.cgi to retrieve the supported XML schema versions.
