ffmpeg-用音频样本填充音频帧

Question

I'm trying to encode an audio stream to a file. I'm receiving the audio buffers and using avcodec_fill_audio_frame to create an AVFrame and send it to avcodec_encode_audio2 (with some other thing in between - I`m using ffmpeg muxing.c as an example)

The thing is: The audio buffer I'm getting contains 480 samples, the codec I'm using has a frame_size of 1152 (MP2). The result is that the output audio file is kinda "chopped". It sounds like every audio frame has some silent samples in the end.

How can I fix this? Thanks!!

Answer 1

You must fill the AVFrame with up to frame_size (1152 in your case) samples before you pass the frame to avcodec_encode_audio2 .

It sounds like your frame is too small. How are you setting it up? Can you show some code?
