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 Khirnov 79a60c8e77 hevc_mvs: initialize the temporal MV in case of missing ref

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.

Anton Khirnov 7b588bb691 svq1: do not modify the input packet 
The input data must remain constant, make a copy instead. This is in

Also, check the size of the header, avoiding invalid reads on truncated
data.

Anton Khirnov 194be1f43e lavf: switch to AVStream.time_base as the hint for the muxer timebase 
Previously, AVStream.codec.time_base was used for that purpose, which
was quite confusing for the callers. This change also opens the path for
removing AVStream.codec.

The change in the lavf-mkv test is due to the native timebase (1/1000)
being used instead of the default one (1/90000), so the packets are now
sent to the crc muxer in the same order in which they are demuxed
(previously some of them got reordered because of inexact timestamp
conversion).

Anton Khirnov 0957b274e3 lavc: add an option to enable side data-only packets during encoding 
Some encoders (e.g. flac) need to send side data when there is no more
data to be output. This enables them to output a packet with no data in
it, only side data.
