how can i decode vp8 stream?

[Yang Song]

hello everyone, i have a question here

how can i decode vp8 stream? here stream means ES stream.

i have read ffmpeg decoding_encoding.c, but the video_decode_example decodes a video codec which is frame based,

however vp8 is frame based. So i have to feed ffmpeg exactly a piece of frame each time.

but how can i know each frame size? i have read vp8 rfc chapter 9 but i still don't know how to get frame size.

any help will be highly appreciated.Thank you all.

Hi,

VP8 generally requires the application to provide framing of the video stream. It can't decode a completely raw stream on its own. This usually comes from the container the video is stored or streamed in.
