Queue.offer(nvertIndexToXYPosition(rectangleData.indexOf(rectTapped), ())) Inspired by many other FFmpeg on Android implementations out there (mainly the guadianproject), I found a solution (with Lame support also).Val seedColor = instance.rectangles?.color ?: Color.WHITE Thanks, Any assistance needed, please let me know. Hope i idid not confuse you more after all this. enable-encoder=mp2 -enable-decoder=mp2 (For Audio support) enable-encoder=mpeg4 -enable-decoder=mpeg4(For video support) PheProgrammatically build.sh should contain the following code: -enable-muxer=avi -enable-demuxer=avi (Generic for both audio/video. Mpeg4 Encoder, mpeg4 decoder, mp2 encoder, mp2 decoder, avi muxer, avi demuxer. So if you want to use avi format, you need to enable Video components + Audio components.Įx, for avi, you need to enable the following. Muxer/demuxer is used to combine/separate the frames from a file used while encoding/decoding. AVI is not a codec, it is a container which uses Video codec of Mpeg4 and Audio codec of mp2. => Audio = encoder + decoder + Muxer + Demuxer(mp2 + mp2 + avi + avi - Example for avi container)Ĭodec(name is deriverd from a combination of en*co*der/*dec*oder) is just a part of format which defines the algorithms used to encode/decode a frame. => Video = encoder + decoder + Muxer + Demuxer(Mpeg4 + Mpeg4 + avi +avi - Example for avi container)

Any vulnerability in decoders for any of the numerous formats could be exploited to gain arbitrary code execution. FFmpeg supports a huge variety of formats, both popular and obscure, for video, audio, and images formats.
When we say a video file, ex : avi, it is combination of both audio and video There are security risks, especially if you allow arbitrary formats. It took a lot of time for me to realize this. Else the corresponding code will not be included in the libraries. You can use either of them.Įxtra tip i would like to offer is that when you are building the ffmpeg code, inside build.sh you need to enable the muxers/demuxers/encoders/decoders of the formats you want to use. You can see two projects named P and P86. Here is a link to the project from or run the command " git clone " in a terminal. In that project you have the whole setup ready which you can use to continue your investigation. Currently it is having bugs but developers are working continuously. This would be your first step.Ģ) Dolphin player is a open source project for Android. You will get an idea as to which API's inside ffmpeg you should call. Here, you can see the code where encoding/decoding is done.
Google has many special features to help you find exactly what youre looking. But i can guide you in following ways.ġ) Inside the ffmpeg directory of source code, you have output_example.c or api_example.c. Search the worlds information, including webpages, images, videos and more.

Now to answer the question of how to use this library, i would say that it is not so simple to write it here. It supports different formats of codecs and containers. ffmpeg is an effort in improving it day by day. The best documentation can be found in the headers.įor various reasons, Multimedia was and is never easy in terms of achieving the task without compromising on efficiency. Regarding using ffmpeg for playback, there are many examples (the ffmpeg binary itself is a good example), here's a basic tutorial. There's enough documentation on JNI out there, you should be fine. Use the ffmpeg-wrapping dynamic library from your java sources. The NDK allows you to easily link against the static libraries you've generated in step 1, just add a line similar to this to Android.mk: LOCAL_STATIC_LIBRARIES := libavcodec libavformat libavutil libc libz Basically you'll need to write some C/C++ code to export the functionality you need out of ffmpeg into a library java can interact with through JNI. There's a lot of documentation out there on how to work with the NDK. The source code of this app is available on GitHub on the link given below. Input and output commands managed by the app. You'll need to extract bionic(libc) and zlib(libz) from the Android build as well, as ffmpeg libraries depend on them.Ĭreate a dynamic library wrapping ffmpeg functionality using the Android NDK. The description of FFmpeg App Now execute FFmpeg commands on your Android smartphone. Simply place the sources under /external and make away.

ts to mp4 ffmpeg android convert mp4 video in video/mp4 codecsavc1. This was achieved by building olvaffe's ffmpeg android port ( libffmpeg) using the Android Build System. FFmpeg is the leading multimedia framework, able to decode, encode, transcode. Build static libraries of ffmpeg for Android.Here are the steps I went through in getting ffmpeg to work on Android:
