Recently in the development of dm368, intends to transplant a gst-rtsp-server on 368. First on the computer to toss a day, finally can run.Gstreamer-0.10 was previously installed on my virtual machine (the GStreamer version is too new and some plugins are not available). GStreamer and Base,good,ugly,bad related plug-in installation did not encounter any problems. Here are the problems I encountered in compiling gst-
One, RTMP, RTSP, HTTP protocolThese three protocols belong to the Application layer protocol in the Internet TCP/IP five layer architecture. Theoretically these three kinds can be used for video broadcast or on-demand. But usually, live broadcast with RTMP, RTSP. And on-demand with HTTP.The following are the characteristics of the following three respectively. The 1,RTMP Protocol (1) is a streaming media pr
Objective:
Using the javacv1.2 version, refer to the code on the Internet, encountered a number of very serious problems, the last one to eliminate the solution. The main issues to be addressed are:
Problem one, ffmpeg default is the way to use UDP, often the problem of packet loss, you need to change the UDP to TCP can be resolved, the following is the content of the error:
Input #0, RTSP, from ' RTSP://A
achieve non-linear upper sampling, the pool index is the decoder corresponding to the encoder for maximum pooling operation calculation. This eliminates the need for learning to sample, maps that are sampled are sparse, and then convolution with a trained filter core to produce dense feature maps. The result of the segmentation is very coarse, mainly because the maximum pooling layer and the reduced sampling reduce the resolution of the feature maps.
1. s60 uses a multimedia framework (MMF) for video and audio playback and recording. It has a plug-in architecture and can use multiple types of plug-ins for media playback and recording, for example, the RealPlayer engine is a plug-in for the MMF controller and supports video and audio playback and stream. 2. The s60 built-in player uses the RealPlayer engine. HTTP streaming media is not supported, because all video data must be read into the cache at one time before display. 3. the common form
With the arrival of 3G, the bandwidth is higher and the traffic fee is lower, and multimedia applications such as mobile phone and TV will surely develop greatly. I will sum up my previous experience, I will discuss with you how to create a VoD solution for mobile phones, and finally provide a preliminary client implementation result. Welcome to the discussion.
First, let's talk about the architecture. For ease of management and expansion, bandwidth restrictions, and multi-user concurrency, comm
Recently, due to the need to implement RTSP-based transmission RM rmvb, no existing solutions have been found on the Internet. Only one live555 has implemented the RTSP service, but only supports RTP transmission of mpg, MP3, WAV and other formats. rm seems very unpopular in the Open Source Field, probably because the formats and protocols are private and not open. Then we started to develop rmvb over

RTP/RTCP/RTSP/SIP/SDP RelationshipRTP (real-time transport protocol, Transport layer)Real-time Transport Protocol) is a Transport layer protocol for multimedia traffic on the Internet. The RTP protocol details the standard packet format for transmitting audio and video over the Internet. RTP protocols are commonly used in streaming media systems (with the RTCP protocol), video conferencing and a Push-to-talk system (with either a/p or SIP), making it
HTTP (Hyper-Text Transfer Protocol), RTSP (Real Time Streaming protocol live Stream Transfer Protocol), RTMP (Routing Table Maintenance Protocol Routing Tables Maintenance Protocolis the application layer protocol, theoretically can do live, on-demand, in fact, live more than rtmp and RTSP, on-demand and more with RTSP and HTTP.

data packets. therefore, the server can dynamically change the transmission rate or even the type of the payload. RTP and RTCP can be used together to optimize transmission efficiency with effective feedback and minimal overhead. Therefore, it is particularly suitable for transmitting real-time online data.

This document records a simple H.265 (HEVC) Video Encoder Based on libx265. The previously recorded encoder uses FFmpeg to call libx265 for encoding. For example:

ASP a very obvious feature is that the page is processed after the server is sent to the browser content in the standard HTML format, so that the effective protection of the original Code of the page program is not easily access by the client (of course, Ms Bugs are constantly that is another matter.) ^_^).
