This directory contains examples of how to use ffmpeg based on the examples here but using the low-level golang bindings.

• decode_audio - libavcodec decoding audio API usage example. Decode data from an MP2 input file and generate a raw audio file to be played with ffplay.
• decode_video - libavcodec decoding video API usage example. Read from an MPEG1 video file, decode frames, and generate PGM images as output.
• demux_decode - ibavformat and libavcodec demuxing and decoding API usage example. Show how to use the libavformat and libavcodec API to demux and decode audio and video data. Write the output as raw audio and video files to be played by ffplay.
• encode_audio - libavcodec encoding audio API usage example. Generate a synthetic audio signal and encode it to an output MP2 file.
• encode_video - libavcodec encoding video API usage example. Generate synthetic video data and encode it to an output file.
• mux - Muxing - libavformat/libavcodec muxing API usage example - NOT COMPLETED Generate a synthetic audio signal and mux it into a container format.

• resample_audio - libswresample API usage example. Generate a synthetic audio signal, and Use libswresample API to perform audio resampling. The output is written to a raw audio file to be played with ffplay.
• scale_video - libswscale API usage example. Generate a synthetic video signal and use libswscale to perform rescaling.
• show_metadata - libavformat metadata extraction API usage example. Show metadata from an input file.
