libextractor: AVCodecContext Struct Reference

Some codecs need additional format info. It is stored here. If any muxer uses this then ALL demuxers/parsers AND encoders for the specific codec MUST set it correctly otherwise stream copy breaks. In general use of this field by muxers is not recommanded.

encoding: Set by libavcodec.
decoding: Set by libavcodec. (FIXME: Is this OK?)

int AVCodecContext::me_method

Motion estimation algorithm used for video coding. 1 (zero), 2 (full), 3 (log), 4 (phods), 5 (epzs), 6 (x1), 7 (hex), 8 (umh), 9 (iter), 10 (tesa) [7, 8, 10 are x264 specific, 9 is snow specific]

uint8_t* AVCodecContext::extradata

some codecs need / can use extradata like Huffman tables. mjpeg: Huffman tables rv10: additional flags mpeg4: global headers (they can be in the bitstream or here) The allocated memory should be FF_INPUT_BUFFER_PADDING_SIZE bytes larger than extradata_size to avoid prolems if it is read with the bitstream reader. The bytewise contents of extradata must not depend on the architecture or CPU endianness.

encoding: Set/allocated/freed by libavcodec.
decoding: Set/allocated/freed by user.

AVRational AVCodecContext::time_base

This is the fundamental unit of time (in seconds) in terms of which frame timestamps are represented. For fixed-fps content, timebase should be 1/framerate and timestamp increments should be identically 1.

decoding: Set by libavcodec.
