A Possible LCEVC Mobile Video Recording?

Most modern consumer mobile computing devices, whether high-end flagship or mid-range, equipped with photo capture and/or video recording have an option to use either JPEG or RAW in photography and either H.264 or H.265 in video, depending on a given quality of performance that often affects the user experience of every consumers. Of course, in order the image or video quality must be in reduced in artifact, every image or video encoding must have an enhanced computing algorithms while reducing data bandwidth and memory capacity without sacrificing the demand of streaming and storage.

Although H.265, better known as HEVC (High Efficiency Video Coding), was now available on flagship high performance cellphones and even professional-grade video cameras, the majority of mid-range performance cellphones, an affordable mobile video vehicle drive surveillance (known as dashcam), and even affordable digital TV tuner box still stuck on H.264. If not only because HEVC has a lot of patent pools as a result of high price tag to pay both on devices and even subscription fee to stream video, then H.264 has a lot of limitations in terms of basic performance and user experience in an attempt to make high quality and high frame rate video at lower bandwidth as a result of terrible artifact.

So why not try LCEVC-compliant H.264 mobile video software recording for mid-range devices? Well, this in my view may be an engineering challenge to substitute standalone HEVC, and that this may take time and effort to make the system perfect for low-income consumers in developing countries. If this would push through, what possible method could program the system?

As a disclaimer, I am not a computer engineer nor an expert in any scientific expertise but rather a guide to suggest for legitimate electronic computing engineering to try to experiment the system.

Suppose an LCEVC-compliant H.264 video recording starts at lower resolution and an optional high frame rate capture as a base layer in default luminance and the succeeding layer has in-between standard and high resolution producing "canvass-style" detail known as "residuals". Depending on software and hardware configuration, the base video encoding may assign on either graphics processing cores while the residual layers may assign on the other cores.

In order that the combined base and residual video layers after recording must be "in-sync" to reduce detail smearing during playback, they must equip with special time stamping as a "stopwatch".

An LCEVC-based H.264 recorded video content has only a near equivalence of HEVC video content in terms of video quality and reduced computing complexity. Depending on the software requirement to decode the content, it may likely work on legacy devices without straining a limited computing power on older mobile processor, mostly ARM-based.

For now, no mobile apps has released to include LCEVC software video recording (such as Open Camera), unless it requires extensive research to experiment the system to become compatible for mid-range mobile video recording devices to consumers.
