I. New Android Studio projectNote the point:1. In the "Create Android Project" section, you must tick the "Include C + + support" check box;2. In the Customize C + + Support Section, C + + standard selects "c++11" in the drop-down list.Two. Configuring support FFmpeg in the AS ProjectNote the point:1. Add FFmpeg dependent libraries. Includes the generated header files and. so files.1.1) Copy the include dir

Compile ffmpeg0.8.1 for Android ndk R6 in the 32-bit Ubuntu 11.04 series of articles-use FFMPEG media library in Android (1) and use the compiled FFMPEG library through JNI in Android-use the FFMPEG media library in Android (2). After the article is published, this article will refer to an open-source project of church labs in GitHub, to illustrate how to use the

line. Ffplay: Video playback program. (requires SDL support) Ffserver: Multimedia server After you understand the structure, you will find that if you are looking for a way to convert the video format, that FFmpeg is definitely your first choice, and Libavcodec is the top priority. If the API does not work, refer to Ffmpeg.c, ffplay.c, FFSERVER.C, apiexample.c (decoding), and output_example.c (encoding).

Transferred from: http://www.cnblogs.com/dwdxdy/p/3625766.htmlSince FFmpeg is an open source project based on Linux, the source code is incompatible with the C + + compiler provided by the most common Visual Studio under Windows, so it cannot be compiled with msvc++ and requires a Linux-like build environment under Windows. This article mainly records the process of FFmpeg compilation under Windows.1. Resou

FFmpeg Video and timestamp watermarkThe project needs to add a timestamp to the video, which is of course the best way to ffmpeg. Before finding the right approach, the answer timecode the Internet (water is not light, 2 days here), presumably this is written:Ffmpeg-i wildlife.wmv-vf "drawtext=fontfile=arial.ttf:text= ' fuck ': timecode= ' 09\:57\:00\:00 ': r=25: \x= ( W-TW)/1.5:y=h-(20*LH): fontcolor=white

Run the FFMPEG command in windows,D:/tools/FFMPEG/bin> ffmpeg.exe-I "Download URL of a video file"-F FLV D:/1.flv You can directly convert the Input Source of the download link to 1.flv.

If there is no path entry under the User Variables setting, click the New button to create it. Enter path in the Variable name field. This method allows the current user to use FFmpeg. Other Windows users are not able to use. If you want each user to be able to use it, you need to add it to the path entry in the system variable ; C:

Recently, my friend asked me to help him write a program to convert various video formats into FLV, here we will share with you the difficulties and experiences encountered in programming. 1. engine used: FFMPEG + mencoder2,

Ffmpeg simple video player and ffmpeg player Refer to Lei Xiaohua's simplest FFMPEG-based video player. There is always a problem when porting code to my linux environment, So I simply analyzed and transplanted Raytheon's code for debugging from start to end. Development Environment: Operating System: ubuntu14 Ffmpeg v

The overall call logic is:1. Compile the FFMPEG Library2. Use JNI to write C code, which must contain the corresponding FFMPEG header file3. Write the corresponding Android. mk file, which specifies the C code to be compiled and the dynamic library to be linked.4. Execute ndk-build to generate the corresponding JNI Library5. Create the andorid Java program. The corresponding

, it needs to be freed by calling Av_free_packet. Av_free_packet calls the destruct function of the struct itself, which has two conditions: 1) av_destruct_packet_nofree or 0;2) Av_destruct_packet, of which, in case 1) Only the value of data and size is cleared by 0, which is 2) to actually release the buffer. The FFmpeg internally uses the Avpacket structure to build the buffer load data, providing the destruct function, and if

Problem scenario: Transcode files with FFmpeg. Problem Description: Use PHP to implement transcoding with three methods called Terminal ffmpeg via exec (), PassThru (), System () The code is as follows: To run this PHP file in the terminal, it can be transcoded normally.However, access to this file via the Web cannot be transcoded. Why??Before the full path of the FFm
