Record

The importance of video is gradually increasing in various industries, especially with the application of artificial intelligence. This makes capturing and recording a large amount of video data crucial. In order to achieve high-quality video recording, post-production, and digital content reuse, we rely on powerful equipment for encoding and decoding. The quality of video encoding and decoding directly impacts the final digital content, and the compatibility of file formats presents challenges for developers.

However, video requirements vary in different industries. In the field of security surveillance, each camera image typically needs to be recorded independently, often requiring simultaneous recording of 32 to 64 high-definition channels. In the broadcast and television industry, news reporting requires real-time video editing, and video from different perspectives must be synchronized for recording. This approach is quite different from other industries. In the medical and financial sectors, privacy and security are paramount. Providing encryption and backing up multiple target files based on different bitrates and resolutions can provide additional security to customers.

Furthermore, professional video recording often requires a deep understanding of encoding and decoding algorithms. If developers are not familiar with the specific characteristics of a particular industry or lack the assistance of professional encoding and decoding technical personnel, they may encounter issues during development, such as bitrate control, video loss, and excessive consumption of system resources.

In summary, video product developers typically face three major challenges :

Encoding and Decoding Technical Capabilities

From MPEG2 to H264/H265, and now to the latest AV1 encoding and decoding, different encoding algorithms require developers to adjust and optimize complex parameters and fine-tune stability and latency, all of which have a decisive impact on project success.

Encoding and Decoding Efficiency Issues

In the past, the CPU was the primary encoding and decoding tool. However, with the rise of GPU technology, developers must learn how to utilize GPU hardware acceleration and CUDA programming to meet the demands of high-resolution and multi-channel recording. Additionally, having a professional CODEC team for technical collaboration with chip manufacturers is crucial when encountering issues in implementing recording on GPUs.

Multimedia Data Formats

Different industries use various data formats, which may be combined into different containers during packaging. For example, the professional audio and video market may prefer MP4, while broadcast television may use TS streams or MPTS multi-stream packaging. In addition, M3U8 technology is indispensable for mobile phones and tablets. This diversity requires developers to support and understand multiple data formats.

Therefore, as a leading manufacturer of audio and video capture cards with 30 years of accumulated experience, YUAN fully understands the challenges that developers face in video recording and editing. It has provided the NexVDO SDK to bridge the gap and make video encoding and decoding more accessible.

NexVDO SDK has the following key features :

GPU Hardware Encoding and Decoding Technology

Traditionally, audio and video compression primarily relied on the processing power of CPUs. However, with the continued development of GPU technology, we have been able to fully harness the potential of powerful GPUs in video encoding and decoding, gradually overcoming the limitations of CPU performance. NexVDO SDK integrates GPU encoding and decoding technologies such as NVIDIA NVENC, Intel MediaSDK, and AMD VCE, allowing developers to easily access these technologies through a unified interface.
 

Diverse Recording Modes

Different industries and applications require different recording modes. NexVDO SDK supports various modes, including pre-recording, synchronous recording, time-shift recording, 3D recording, multi-data stream recording, and encrypted recording. This diversity allows us to meet the needs of different industries, whether it is surveillance requiring simultaneous recording of multiple channels or the medical field requiring precise synchronous recording and 3D recording.

Professional Playback and Editing Engine

NexVDO SDK has redesigned the file playback engine, especially catering to the high demands of the professional broadcasting market for frame-by-frame playback and editing, as well as the requirements of the security market for rewind playback and the needs of game streaming for replaying exciting segments.

NexVDO SDK provides a complete solution to help developers overcome various challenges in audio and video recording, providing high-quality audio and video recording, post-production, and digital content creation. Whether your application scenario is surveillance, broadcasting, medical, or any other field, NexVDO SDK offers powerful support to make your application stand out.
