[FFmpeg-devel] [PATCH] Description of avcodec_encode_audio()
Fri Apr 3 11:05:52 CEST 2009
You really seem to be missing my point here. Let me give you an example.
I wish to encode 1920 samples of audio to a 16-bit PCM format, say for example using CODEC_ID_PCM_S16BE.
I need to set the size of the output buffer, buf_size, to 1920 * 2 = 3840 to achieve that.
But that is less than FF_MIN_BUFFER_SIZE so I am in conflict with the instructions for the function.
And furthermore, according to the instruction the number of samples read from input would be:
buf_size * input_sample_size / output_sample_size
= 3840 (wrong, it is 1920 samples)
