Anton Khirnov 7784f47762 lavf: stop using avpriv_flac_parse_streaminfo()
The only parameters needed by the demuxers are the sample rate and sample
count, which can be trivially extracted manually, without resorting to
an avpriv function.

Anton Khirnov 56dc46a189 riffenc: do not fall back on AVCodecContext.frame_size for MP3
It will not be set unless the codec context is used as the encoding
context, which is discouraged. For MP2, av_get_audio_frame_duration()
will already set the frame size properly. For MP3, set the frame size
explicitly.

Anton Khirnov 874792641e vorbis_parser: use a dedicated AVClass for logging
Currently, the API takes an external AVCodecContext, which is used only

an AVCodecContext in the following commits.

Anton Khirnov 685be3d1ae libvpxenc: add static-thresh private option
Currently, this option is accessed through AVCodecContext.mb_threshold,
which originally controlled reusing MB data when transcoding mpeg to
mpeg. Since the libvpx meaning is completely different from the original
mpegvideo meaning, it is better to use a separate private option for
this.

Anton Khirnov 2d6e58497e lavf: switch to AVCodecContext.framerate for demuxing 2014-10-15 06:37:55 +00:00
Anton Khirnov 7ea1b3472a lavc: deprecate the use of AVCodecContext.time_base for decoding
When decoding, this field holds the inverse of the framerate that can be
written in the headers for some codecs. Using a field called 'time_base'
for this is very misleading, as there are no timestamps associated with
it. Furthermore, this field is used for a very different purpose during
encoding.

Add a new field, called 'framerate', to replace the use of time_base for
decoding.

Anton Khirnov eabdc2a830 lavf: use initial_padding instead of deprecated delay 2014-10-13 19:10:30 +00:00
Anton Khirnov 2df0c32ea1 lavc: use a separate field for exporting audio encoder padding
Currently, the amount of padding inserted at the beginning by some audio
encoders, is exported through AVCodecContext.delay. However
- the term 'delay' is heavily overloaded and can have multiple different
  meanings even in the case of audio encoding.
- this field has entirely different meanings, depending on whether the
  codec context is used for encoding or decoding (and has yet another
  different meaning for video), preventing generic handling of the codec
  context.

Therefore, add a new field -- AVCodecContext.initial_padding. It could
conceivably be used for decoding as well at a later point.

Anton KhirnovandMichael Niedermayer d92550d191 lavf: eliminate ff_get_audio_frame_size()
It is basically a wrapper around av_get_audio_frame_duration(), with a
fallback to AVCodecContext.frame_size. However, that field is set only
when the stream codec context is actually used for encoding or decoding,
which is discouraged.

For muxing, it is generally the responsibility of the caller to set the
packet duration.
For demuxing, if the duration is not stored at the container level, it
should be set by the parser.

Therefore, removing the frame_size fallback should not break any
important case.
