eXtra-fast Essential Video Encoder (XEVE)

The eXtra-fast Essential Video Encoder (XEVE) is an opensource and fast MPEG-5 EVC encoder.

MPEG-5 Essential Video Coding (EVC) is a video compression standard of ISO/IEC Moving Picture Experts Group (MPEG). The main goal of the EVC is to provide a significantly improved compression capability over existing video coding standards with timely publication of terms. The EVC defines two profiles, including "Baseline Profile" and "Main Profile". The "Baseline profile" contains only technologies that are older than 20 years or otherwise freely available for use in the standard. In addition, the "Main profile" adds a small number of additional tools, each of which can be either cleanly disabled or switched to the corresponding baseline tool on an individual basis.

Quality comparison

MPEG-5 Baseline Profile vs. MPEG-4 AVC/H.264

MPEG-5 EVC Baseline Profile can show 2-times better coding gain over MPEG-4 AVC/H.264 codec and superior quality on the same bitrate

MPEG-5 Main Profile vs. HEVC/H.265

MPEG-5 EVC Main Profile can show 2-times better coding gain over HEVC/H.265 codec and superior quality on the same bitrate

Programming Guide

The following code is a pseudo code for understanding how to use the library

#include <xeve.h>

#define MAX_BITSTREAM_SIZE (10*1000*1000) /* 10Mbyte, need to be set properly */

/* prepare coding parameters ***************************/
XEVE_CDSC cdsc;
cdsc.max_bs_buf_size = MAX_BITSTREAM_SIZE;

/* get default parameters */
xeve_param_default(&cdsc.param);

/* set specific profile, preset, tune, if needs */
xeve_param_ppt(&cdsc.param, XEVE_PROFILE_BASELINE, XEVE_PRESET_SLOW, XEVE_TUNE_NONE);

/* create new instance *********************************/
XEVE id = xeve_create(&cdsc, NULL);

/* encode pictures *************************************/
XEVE_BITB bitb; /* bitstream buffer */
memset(&bitb, 0, sizeof(XEVE_BITB));
bitb.addr = malloc(MAX_BITSTREAM_SIZE); /* assign buffer */
bitb.bsize = MAX_BITSTREAM_SIZE;

XEVE_STAT stat; /* encoding status */
XEVE_IMGB image; /* input picture */

while (!end_of_sequence)
{
    end_of_seqeunce = read_image(&image); /* read new image */

    xeve_push(id, &image); /* input new image to encoder */
    ret = xeve_encode(id, &bitb, &stat); /* actual encode image to bitstream */

    if (ret == XEVE_OK && stat.write > 0)
    {
        write_bitstream(bitb.addr, stat.write); /* write encoded bitstream */
    }
}

/* clean-up ********************************************/
xeve_delete(id);
