When you compile code, the output depends on the architecture target. Arm cpus are most common, but x86 is unusual. arm-v7a, arm-v7a-neon, arm64-v8a, x86 and x86_64īasically, a given Android device might have an arm or an x86 cpu, these are just different architecture types from different manufacturers.No extra code required when we use pre-defined queries. Let’s take one example of query: Cut a small part from video using time val query : Array = “-i”, “input video path.MP4”, “-ss”, “startTime(00=hrs:00=Min:00=Sec:00=m.Sec)”, “to”, “endTime(00=hrs:00=Min:00=Sec:00=m.Sec)”, “-r”, “$FRAME_RATE”, “-preset”, “ultrafast”, “output video path.MP4”Īdd an easy way to execute the In-build command(Query): val startCutTimeString = "00:01:00" (HH:MM:SS) val endCutTimeString = "00:02:00" (HH:MM:SS) val query:Array = FFmpegQueryExtension.cutVideo(inputPath, startCutTimeString, endCutTimeString, outputPath) CallBackOfQuery.callQuery(this, query, object : FFmpegCallBack )

To integrate FFmpeg in your android application you can use pre-compiled libraries like FFmpeg, which provide multiple predefined multimedia operations(Queries) and which is easy to integrate by adding FFmpeg dependency in app module gradle file and sync project.

Supports zlib and Media-codec system libraries.

Finally those are passed to the muxer, which writes the encoded packets to the output file. After filtering, the frames are passed to the encoder, which encodes them and outputs encoded packets. The decoder produces uncompressed frames, which can be processed further by filtering. When there are multiple input files, FFmpeg tries to keep them synchronized by tracking lowest timestamp on any active input stream.Įncoded packets are then passed to the decoder. FFmpeg calls the libavformat library (containing demuxers) to read input files and get packets containing encoded data from them.
