Anton Khirnov 09ae7b81ea flvdec: do not create any streams in read_header() The current muxer behaviour is to create streams in read_header() based on the audio/video presence flags, but fill in the stream parameters later when we actually get some packets for them. This is rather shady, since other demuxers set the stream parameters immediately when the stream is created and do not touch the stream codec context after that. Change the flv demuxer to behave in the same way as other similar demuxers -- create the streams only when we get a packet for them.		2015-12-12 21:26:48 +01:00
