[FFmpeg-devel] output pictures storage?

[boku]

Dear all,
    I'm studying the ffmpeg libavcodec and wonder where the output frames or
pictures are stored?
Is it the AVFrame->uint8_t *data[4]; ?
    Secondly, do you know which functions is to do the malloc for those
output buffers?
Is it int (*get_buffer)(struct AVCodecContext *c, AVFrame *pic)  of
AVCodecContext?

Thank you!
BR,
