9f0b6e6827 vocdec: do not create the stream in read_header() 
The stream parameters are not known until we read a packet, so postpone
creating it until then.

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.

72d658766e mp3dec: replace avpriv_mpa_decode_header with avpriv_mpegaudio_decode_header 
The latter does not require a full AVCodecContext and still provides all
the functionality needed here.

955aec3c7c mpegaudiodecheader: check the header in avpriv_mpegaudio_decode_header 
Almost all the places from which this function is called already check
the header manually and in the two that don't (the mp3 muxer) the check
should not cause any problems.

9f1eccb97b ff_parse_specific_params: do not use AVCodecContext.frame_size 
It will not be set unless the muxing codec context is also the encoding
context, which is discouraged. When the frame size is not known from
av_get_audio_frame_duration(), the fallback should still be good enough.

1f008f34d5 rmenc: do not use AVCodecContext.frame_size 
It will not be set if the stream codec context is not the encoding
context. Use av_get_audio_frame_duration() instead, it should work for
all audio codecs supported by the muxer.

for mov files but was not done for A_QUICKTIME" mkv files.
