JCodec is a pure Java implementation of popular video and audio codecs, including H.264, VP8, MPEG, ProRes, and AAC, along with container demuxers/muxers like MP4, MKV, and MPEG TS. It runs on standard Java and Android with no native dependencies.

Use cases

• decode h264 video in pure java without native libraries
• encode or decode mp4 files from java
• extract frames from video in an android app
• demux or mux matroska mkv files in java
• convert video frames to bufferedimage in java
• read prores video files in jvm applications
• process mpeg ts streams in java

When to choose

• you need video/audio codec functionality in pure Java or on Android without native dependencies
• you want a BSD-licensed library for MP4/MKV demuxing and muxing on the JVM
• you need basic H.264 decoding or ProRes encode/decode in a Java application

When to avoid

• you need high performance or full-featured encoding/decoding - native libraries like FFmpeg are far faster and more complete
• you need advanced H.264 encoding features like CABAC or rate control, which are not yet implemented
• you need MP3 decoding or AAC encoding, which are still on the roadmap
