[FFmpeg-devel] [PATCH] doc/examples/decode_audio: read the audio data from data[0]

[Steven Liu]

only frame linesize[0] can get length size,
i have tested before patch like this:
ffmpeg -i /Users/liuqi/input.mp3 -codec:a ac3 -ac 5 a.ac3
./doc/examples/decode_audio a.ac3 a.pcm
ffplay -f f32le -ac 5 -ar 44100 a.pcm
