1080P HD display at the same time. Ability to create powerful virtual machinesWith Workstation Pro, you can now create virtual machines with up to 16 virtual CPUs, 8 terabytes of virtual disks, and up to five GB of memory to run the most demanding desktop and server applications in a virtual environment. You can make graphics-intensive applications more capable of processing by assigning up to 2 GB of video memory for virtual machines. support for th
To play and record audio on iOS devices, Apple recommends that we use the Avaudioplayer and Avaudiorecorder classes in the Avfoundation framework. Although the usage is simpler, it does not support streaming; This means that before playing the audio, you must wait until the entire audio load is complete before you can start playing the
how to make video and audio time-stampinghttp://blog.csdn.net/wfqxx/article/details/5497138
1. Video time stamp
PTS = inc++ * (1000/fps); Where Inc is a static, initial value of 0, each time the timestamp Inc plus 1.
In FFmpeg, the code in
pkt.pts= m_nvideotimestamp++ * (M_vctx->time_base.num * 1000/m_vctx->time_base.den);
2. Audio time stamp
PTS = inc++ * (frame_size * 1000/sample_rate)
The code in FFmpeg
Real-time audio and video domain UDP is the king
In the Internet, audio and video real-time interaction using the Transport Layer Scheme has TCP (such as: RTMP) and UDP (such as: RTP) two kinds. The TCP protocol can provide a relatively reliable guarantee for data transmission between two endpoints, which is achieved through a handshake mechanism. When the data is passed to the receiver, the receiver checks

As a mid-range product, advanced features such as SLI and SDI are not provided. However, FX 1800 has the essence of quadro: Cuda GPU computing.
Cuda (compute unified device architecture) is a new infrastructure that uses GPU to solve complex computing problems in business, industry, and science. It is a complete gpgpu solution that provides direct access interfaces for hardware, without the need to rely on graphical API interfaces to achieve GPU access in the traditional way.
