After work everyone likes to watch video to pass the time, many Win8 system users download the use of the Storm audio and video player to watch videos, with hundreds of kinds of TV dramas. Sometimes you turn on the storm. Video playback The problem that cannot play the next episode automatically, and the error code "40

In practice, you need to change the two time parameter values! The command parameters are described as follows:
-O outputted target file name

During this period of time on csdn, many people in the same industry, especially those who use FFMPEG for video/audio encoding/decoding, some of which have many years of experience ", some are just beginners. During my discussion with you, I suddenly found a problem: There seems to be an insurmountable gap between the "Great God" and beginners.

the sampling frequency is the sampling period or the sampling time, which is the time interval between the samples. The popular speaking sampling frequency is refers to the computer each second gathers how many sound samples, is describes the sound file the quality, the tone, the measurement sound card, the sound document standard. In today's mainstream acquisition card, sampling frequency is generally divided into 22.05KHz, 44.1KHz, 48KHz three levels, 22.05KHZ can only achieve FM broadcast so

If you need to access images, audios, and videos of different encoding formats in your work, you are likely to be using multiple tools to convert these diverse media formats. It would be great if there is a multi-in-one conversion tool that can process all image/audio/video formats. FormatJunkie is such a multi-in-one media conversion tool, which has an extremely friendly user interface. Even better, it is

The purpose
1, ES Stream (Elementary stream), original stream. is a A/D conversion, encoded after the output of the data stream, is directly from the encoder output data stream;
1) ES is packaged in PES and converted to PES packs.
2) ES is a stream of data that contains only one content, such as audio data or video data.
3) A packaged PES stream contains only one content.
2, PEs stream (Packet Elementary Stream), the
WEBRTC source code, the transmission and reception of video packets is taken as an example, and the implementation of Anck packet retransmission mechanism is deeply analyzed. The main contents include: SDP negotiation Nack, receiving end packet loss determination, NACK message construction, sending, receiving and parsing, RTP packet retransmission. The following are discussed in detail.I. SDP negotiation NACKThe nack is used as the RTP layer feedback
