see av_find_best_pix_fmt_of_2()
Global avcodec_get_edge_width (void)
CODEC_FLAG_EMU_EDGE is deprecated, so this function is no longer needed
Global avcodec_get_pix_fmt_loss (enum AVPixelFormat dst_pix_fmt, enum AVPixelFormat src_pix_fmt, int has_alpha)
see av_get_pix_fmt_loss()
Global avcodec_set_dimensions (AVCodecContext *s, int width, int height)
this function is not supposed to be used from outside of lavc
Global AVCodecContext::codec_name [32]
this field is not used for anything in libavcodec
Global AVCodecContext::error_rate
use the 'error_rate' private AVOption of the mpegvideo encoders
Global AVCodecContext::get_buffer )(struct AVCodecContext *c, AVFrame *pic)
use get_buffer2()
Global AVCodecContext::pkt
this field is not supposed to be accessed from outside lavc
Global AVCodecContext::release_buffer )(struct AVCodecContext *c, AVFrame *pic)
custom freeing callbacks should be set from get_buffer2()
Global AVCodecContext::reordered_opaque
in favor of pkt_pts
  • encoding: unused
  • decoding: Set by user.
Global AVCodecContext::request_channels
Deprecated in favor of request_channel_layout.
Global AVCodecContext::thread_opaque
this field should not be used from outside of lavc

this field is unused
Global AVFrame::reordered_opaque
in favor of pkt_pts
Global avpicture_deinterlace (AVPicture *dst, const AVPicture *src, enum AVPixelFormat pix_fmt, int width, int height)
- use yadif (in libavfilter) instead
no codecs use this capability
edges are not used/required anymore. I.e. this flag is now always set.
use the "gmc" private option of the libxvid encoder
passing reference-counted frames to the encoders replaces this flag
use the flag "mv0" in the "mpv_flags" private option of the mpegvideo encoders
use the flag "naq" in the "mpv_flags" private option of the mpegvideo encoders
File dict.h
AVDictionary is provided for compatibility with libav. It is both in implementation as well as API inefficient. It does not scale and is extremely slow with large dictionaries. It is recommended that new code uses our tree container from tree.c/h where applicable, which uses AVL trees to achieve O(log n) performance.
this option does nothing
there is no libavcodec-wide limit on the number of B-frames
Group lavc_resample
use libswresample instead
use the AV_PIX_FMT_FLAG_* flags
Global sws_format_name (enum AVPixelFormat format)
Use av_get_pix_fmt_name() instead.
Global sws_getContext (int srcW, int srcH, enum AVPixelFormat srcFormat, int dstW, int dstH, enum AVPixelFormat dstFormat, int flags, SwsFilter *srcFilter, SwsFilter *dstFilter, const double *param)
Use sws_getCachedContext() instead.
