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 d754ed4172 riffenc: take an AVStream instead of an AVCodecContext 
It will be useful in the following commits.

Also, rename the AVCodecContext pointer name from 'stream' to 'codec'.

Anton Khirnov f792d3cbb8 lavf: add the notimestamps flag to the muxers missing it 2014-06-18 15:03:31 +02:00
Anton Khirnov cfbdd7ffbd rtpenc: base max_frames_per_packet on avg_frame_rate, not codec timebase 
Fall back to 1 (which is what is used for most cases anyway) when the
framerate is not set.

Anton Khirnov 894682a973 Remove avserver. 
It has not been properly maintained for years and there is little hope
of that changing in the future.
It appears simpler to write a new replacement from scratch than
unbreaking it.

Anton Khirnov e19d48dfce flac muxer: support reading updated extradata from side data 2014-06-01 08:32:33 +02:00
Anton Khirnov 0097cbea69 flac muxer: accept only STREAMINFO extradata 
The other format (full flac header blocks) should not be exported by any
demuxers anymore.

This allows to drop an avpriv_ function and also simplify the following
commits.

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.

Anton Khirnov 43e7f0797f flvenc: only write the framerate tag based on avg_frame_rate 
Do not fall back on the codec timebase, since that can be anything for
VFR video.

Anton Khirnov cf6977712c movenc: write avg_frame_rate as the framerate, not the codec timebase 2014-05-29 08:01:23 +02:00
Anton Khirnov 81eec081af matroskaenc: base DefaultDuration on the framerate, not the codec timebase 
This results in DefaultDuration not being written when the framerate is
not known, but as this field is purely informative, this should not
break any sane demuxers.

It is commonly stored in a vorbiscomment block in codec private data.
 2014-05-28 07:50:32 +02:00
Anton Khirnov 4efdadc8ec matroskadec: export just the STREAMINFO block as FLAC extradata 
It contains all information that is used by the decoder and the other
FLAC-capable demuxers (flacdec, ogg) export only STREAMINFO as well.

Anton Khirnov 5fdaf312c5 flac: make avpriv_flac_parse_block_header() inline 
This avoids all the ABI troubles associated with avpriv_.
Since this function is very small and does not depend on any tables,
making it inline should have no adverse effects.

Anton Khirnov f13ffb6636 flacdec: do not overwrite a channel layout set by the caller 
The channel layout mask for non-standard layouts is typically stored at
the container level (as a vorbiscomment tag) for FLAC.

Anton Khirnov cdf58f0599 avpacket: fix copying side data in av_packet_copy_props()

 2014-05-18 10:19:35 +02:00
Anton Khirnov fd056029f4 lavc: add avcodec_free_context(). 
Right now, the caller has to manually manage some allocated
AVCodecContext fields, like extradata or subtitle_header. This is
fragile and prone to leaks, especially if we want to add more such
fields in the future.

The only reason for this behaviour is so that the AVStream codec context
can be reused for decoding. Such reuse is discouraged anyway, so this
commit is the first step to deprecating it.
