FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

• libavcodec provides implementation of a wider range of codecs.
• libavformat implements streaming protocols, container formats and basic I/O access.
• libavutil includes hashers, decompressors and miscellaneous utility functions.
• libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
• libavdevice provides an abstraction to access capture and playback devices.
• libswresample implements audio mixing and resampling routines.
• libswscale implements color conversion and scaling routines.

Tools

• ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
• ffplay is a minimalistic multimedia player.
• ffprobe is a simple analysis tool to inspect multimedia content.
• Additional small tools such as aviocat, ismindex and qt-faststart.

Ffmpeg custom

How can I use custom command ffmpeg cli Android

Unknown encoder 'libx264'

Hi I use this command which should work but it's not:

ffmpeg -i rtsp://0.tcp.ngrok.io:15082/stream.sdp1 -vcodec libx264 -vb 150000 -g 60 -vprofile baseline -level 2.1 -acodec aac -ab 64000 -ar 48000 -ac 2 -strict experimental -f mp4 /sdcard/a.mp4

The error says "Unknown encoder 'libx264'"

Did you support x264?

"No Java Virtual Machine has been registered" error

Hello,
I compiled FFmpeg on my machine to enable "mediacodec" library.
This is the command line to configure the compilation:

./configure --cross-prefix=/root/arm64-toolchains-r14b/bin/aarch64-linux-android- --sysroot=/root/arm64-toolchains-r14b/sysroot/ --arch=arm64 --target-os=android --extra-cflags="-pie" --extra-ldflags="-pie" --bindir="$HOME/bin" --enable-gpl --disable-shared --enable-static --enable-runtime-cpudetect --enable-hwaccels --enable-neon --enable-jni --enable-mediacodec --enable-decoder=hevc_mediacodec --enable-omx --enable-nonfree --enable-pthreads

The FFmpeg command line works just fine.
However, when I run FFmpeg with "mediacodec" decoder decode a video sequence I got the error below.
Here is the command I used: "-vcodec hevc_mediacodec -i <video_sequence> -f null /dev/null"

如何編譯出 libffmpeg_arm64.so

大神你好我有購買你的專業版因為我想要增加 x264 x265等功能,
按照你的How to Compile FFmpeg有成功編譯出來,
libavcodec.a ibavfilter.a libavutil.a libswscale.alibavdevice.a libavformat.a libswresample.a
這幾個檔,
請問我要如何將這些檔案打包成 libffmpeg_arm64.so 作為客製化的二進制檔案自己使用,
下面是我的編譯腳本希望大神能指引一些步驟方向,
謝謝

failed with custom ffmpeg

I've added custom ffmpeg build and got the following error, which is obviously related to the apk:

Unrecognized option 'magiclen.org'.
Error splitting the argument list: Option not found

Error splitting the argument list: Option not found

我下載了 FFmpeg-For-MagicLen-Applications-3.0.2的 ffMpeg源代碼,
和您提供的配置文件,build_arm.sh 在修改了NDK路徑之後, 成功編譯出了arm 和arm_neon 文件夾的libffmpeg.so,但是我在執行libffmpeg.so的時候,提示我如下信息:

Welcome to my website:
https://magiclen.org
Error splitting the argument list: Option not found

我開始以為是編譯so文件的問題,所以我直接使用您編譯的libffmpeg_arm.so
同樣的提示.

另外,
我執行的命令是 /data/data/... libffmpeg.so -version .
我使用您編譯的ffmpeg 2.3 的so文件,是可以成功執行命令行的.
我想使用最新版本的ffmpeg, 我的源代碼MainActivity

期待您的回復.

作者你好！你可不可以再额外编译一个arm静态连接版本的ffmpeg二进制程序？

如题，感觉APP版本不如命令行的好用
