Hi Guys, I'm using libswresample to convert audio between different sample format (planar format to packed format).
To init swcontext I need input audio channel_layout. But today I found a video, when avcode_open called on it to get audio codec, the returned AVCodecContext has channels field 1, but channle_layout 0. Since 0 channle_layout will cause swcontext init error, I'd like to know what 1 channels but 0 channel_layout means and if there's a workaround so that I can call sw resample successfully? Great thanks!
