High Efficiency Image File Format (HEIF)

https://en.wikipedia.org/wiki/High_Efficiency_Image_File_Format

High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. It was developed by the Moving Picture Experts Group (MPEG) and is defined as Part 12 within the MPEG-H media suite (ISO/IEC 23008-12). MPEG claims that a HEIF image using HEVC requires about half the storage space as the equivalent quality JPEG. HEIF also supports animation, and is capable of storing more information^{[citation needed]} than an animated GIF or APNG at a small fraction of the size.

Introduced in 2015, HEIF was adopted by Apple in 2017 with the introduction of iOS 11, and support on other platforms is growing.

HEIF files are a special case of the ISO Base Media File Format (ISOBMFF, ISO/IEC 14496-12), first defined in 2001 as a shared part of MP4 and JPEG 2000. This file format standard covers multimedia files that can also include other media streams, such as timed text, audio and video.

High Efficiency Image Container (HEIC) in iOS 11 and macOS High Sierra in 2017.

HEIC And HEIF

HEIC is the container or file extension that holds HEIF images or sequences of images. HEIF borrows technology from the High Efficiency Video Compression (HEVC) codec, also known as h.265. Both HEVC and HEIF are proprietary technologies developed by the Moving Picture Experts Group (MPEG).

HEIF came into the mainstream when Apple made it the default format for its pictures on iOS11 devices and macOS High Sierra. However, other operating systems or websites don’t yet support HEIF and its HEIC file extension, so Apple’s operating systems will automatically convert the images to JPEG when users want to share them with friends who don’t use Apple products.

HEIC files can store not just multiple individual images, but also their image properties, HDR data, alpha and depth maps, and even their thumbnails.

Exploring the Kanda QooCam 4K - pass1

I was hoping  to get live streaming off this camera, and it would appear if you have a 64 Bit android device their app can see a live video feed?

There is a Live option on the windows app that appears to do nothing.

 The USB doesn't show up as a video driver.


You can connect with the device over Wifi

To do this power on the device and wait for the power up tune to play.

one well timed (approx 1 second) power button push and it will beep and the blue wifi like will come on.

Scanning your wifi network SSID's, and you will see something like:

QOOCAM-06515

your camera id will vary based on the last 5 digits of the serial number.

password is : 12345678




From Linux, this command works but I was seeing many errors.

DVB Steering Board Approves Phase 2a of 3DTV Specification

DVB is pleased to announce that at the 71st Meeting of the Steering Board, Phase 2a of the DVB-3DTV specification was approved. The specification will be submitted immediately to the European Telecommunications Standards Institute (ETSI) for formal standardisation. An amended DVB-3DTV BlueBook is to be published to reflect the addition to the specification.

The Phase 2a system, also known as “Service Compatible Mode” is designed to meet the needs of those who need to provide normal HDTV receivers with a 2D version of the 3D programme from the same broadcast channel, and at the same time improve the quality of the 3DTV images. Phase 2a provides a 2D version plus an MPEG MVC top-up signal. Although they are tailored to their different environments, both 3D Blu-ray and Phase 2a use MVC, which will enable receivers to include both capabilities.

The 3DTV Phase 1 specification was published in 2011 for “Frame Compatible” delivery, where the essential requirement was that existing HDTV set-top boxes would allow viewers to watch 3D (if they had a 3D display). This is the most used 3DTV broadcast form in the world today.

Code to create MPEG2 transport stream or a program stream

MonoLite, MPEG2Repair & NullPacketSaver MPEG2 transport stream tools

Unfortunatly these are just windows EXE's and no code, sorry linux users :(

This is code from Mark Wilczynski

From MPEG2 HDTV Transport Stream Tools:

monoLite - Alternative TS file player for NMT based media players.
Alternative player application for NMT (Network Media Tank) based media players such as the PCH-A100, PCH-A110, and others from E-Great, HDX, etc.


MPEG2Repair - Used to find and repair errors in MPEG2 transport stream files.  Windows application for testing HDTV transport streams to make sure they are Mpeg2 compliant. It detects and repairs low level .ts (transport stream) errors. It is useful for fixing MPEG2 streams received via broadcast systems like ATSC or DVB, before loading them into other video editing and/or repair tools like VideoRedo or ProjectX.



NullPacketSaver - Used for splitting, joining, and null packet backup of MPEG2 transport stream files.


It looks like this code's moved around a bit since he's hosting it on his DSL/Cable Providers site.   A google on mwilczyn is interesting.

Samsung Chromebook Series 5

Samsung Chromebook Series 5 Review & Rating | PCMag.com

There have been some improvements since Google debuted Chrome OS in the CR-48. For one, Flash support, particularly high-definition videos from YouTube and Hulu, has reaped the benefits of hardware acceleration. Videos played back smoothly and lag-free for the most part, but I would have liked Chrome OS to default to a better video quality than 360p . You have to manually adjust to a higher quality setting. When I say HD support, I really mean 720p max (1080p videos choked in YouTube).

A new media player is also included with Chrome OS plays back actual video and music files, as opposed to streaming them from a Web-based service like Amazon's Cloud Player, Pandora, Slacker, etc. But it's very primitive and the media files will have to come from an external device, such as a USB storage devices or an SD card (through the 4-in-1 media card slot). Chrome OS recognizes external storage devices almost immediately, and you browse through files and folders like you would with Windows. The media player handled 1080p MP4 video files and most audio formats very well, even those that were encoded at high bit-rates. But it also left out a bunch of video formats: The media player isn't compatible with mpeg, AVI, WMV video files, and certainly not Blu-ray.

Video is the future! It's one of the few things I am sure of.

  You would think Chrome OS out the gate would focus on that first and foremost.  Everything else being far easier and less demanding other the maybe 3D graphics rendering.

Nero Files Antitrust Complaint Against MPEG-LA

From Slashdot:
"German technology company Nero AG has filed an antitrust complaint against the MPEG-LA, the company that manages the H.264 patent pool. Nero claims that the MPEG-LA has violated the law and achieved and abused 100% market share, by, among other things, using 'independent experts' that weren't independent after all, not weeding out non-essential patents from the pool (in fact, it has grown from the original 53 to more than 1000), and retroactively changing previously-agreed-on license terms."

AMR codec source code and Standards docs.

Adaptive Multi-Rate (AMR) is a patented audio data compression scheme optimized for speech coding. AMR was adopted as the standard speech codec by 3GPP in October 1998 and is now widely used in GSM and UMTS mobile phone standards.
AMR is also a file format for storing spoken audio using the AMR codec. Many modern mobile telephone handsets will allow you to store short recordings in the AMR format, both open source (see the external links) and commercial programs exist to convert between this and other formats such as MP3, although it should be remembered that AMR is a speech format and is unlikely to give ideal results for other audio. The common filename extension is .amr.
