Recently, due to freerdp, ffmpeg needs to be installed. However, yum cannot be installed and related rpm packages cannot be found for installation. You have to use the source code to install it in RedHat. For details, see the following steps. 1. Download ffmpeg. I am in this region Recently, due to freerdp, ffmpeg needs to be installed.

The more important functions and data structures in FFMpeg are as follows: 1. Data structure: (1) Avformatcontext (2) Avoutputformat (3) Avinputformat (4) Avcodeccontext (5) Avcodec (6) Avframe (7) Avpacket (8) Avpicture (9) Avstream 2. Initialization function: (1) Av_register_all () (2) Avcodec_open () (3) Avcodec_close () (4) Av_open_input_file () (5) Av_find_input_format () (6) Av_find_stream_info () (7) Av_close_input_file () 3.

The multimedia framework opencore of the andorid platform supports the following audio formats: audio pp(.3gp-4、mpeg-4(.mp4 ,. m4a), MP3, Type 0 and 1 (. mid ,. xmf ,. mxmf ). also rtttl/RTx (. rtttl ,. RTX), audio) (commonly used relatively more than ,、wave(.wav). Only two video formats are supported: 3GP and MP4. Obviously, too few video formats are supported, it is far from enough to make a general multimedia player. Such formats as RM, rmvb, and Avi are the most common video formats. We can

About 3GPP In todays mobile phones the 3GPP standard is widely in use for videos on the phone. Newer camera mobiles can take movies from their integrated camera which are encoded in 3GPP (usually with suffix. 3GP ). Currently, 3GPP standards are widely used in mobile phone video screens. Recently, mobile phones can use their own integrated cameras to take a 3GPP-encoded movie (usually later. 3GP ). 3GPP stands for 3rd Generation Partnership project and is a c

There is no good in Linux under the integrated dev

During video processing, you usually need to codec the video data. At this time, using the open-source FFMPEG video and audio processing solution is the choice of most programmers, after all, writing your own codecs is too inefficient, and in most cases it is not enough to write... However, it is only the first step to use FFMPEG, because it is quite troublesome to build the environment later. There are tw

This document records a video transcoding device based on FFmpeg on an Android platform. The transcoding is actually ported from the FFMPEG.C source code in the FFmpeg project. For FFMPEG.C source code can refer to the article "FFMPEG.C function structure simple analysis (Drawing)", here will not repeat the record.SourceThe directory structure of the project. The Java source code is in the SRC directory, an

We plan to record two examples of the simplest FFMPEG for memory read/write. All previous FFMPEG examples operate on files. For example, "100-line code implementation of the simplest Video Player Based on FFMPEG + SDL" plays a video file. The simplest FFMPEG-based transcoding program also converts a video file into ano
