Transcoder Guide

Supported Card Model:

• Nvidia

  • P4000 (support h264/h265)

  • tesla k10 (support h264)

  • includes cuda decoding.

• Intel

Integration Steps:

• Nvidia

  • Install Ubuntu 16, 20

  • Install Nvidia driver and Nvidia ffmpeg.

    • installation steps

    • copy new ffmpeg into ezserver folder

• Intel

  • install Intel QuickSync driver and its ffmpeg

    • read the ffmpeg part of the pdf.

    • copy new ffmpeg into ezserver folder

Panel Setting 

GPU Trasncoding:

• Add UDP, HTTP or RTMP input Links into Channel: Media source.

 

• If the server has 2 network cards, the 1st card for HLS output and the 2nd card for multicast input. Click More icon of the channels to select the 2nd card for input  as below.

• Select Adaptive Bitrate.

• Set Desired bitrate (unit: kbps).

• Select Video Format (h264, h265).

  • h264_nvenc and h265_nvenc options use Nvidia GPU resource.

• URL for restreamer or players

  • Syntax: http://ip_address:port/ChannelName.m3u8?u=xxxx:p=xxxx

  • Syntax: http://ip_address:port/chx.m3u8?u=xxxx:p=xxxx

  • Ex. 1: http://test:1234@172.16.10.50:8000/TV1.m3u8

  • Ex. 2: http://test:1234@172.16.10.50:8000/ch4.m3u8

Examples:

• Option 1: Single Bitrate: 500kbps and video format :h264_nvenc.

• for h264_nvenc supports udp, http and rtmp input link.

• Option 2: Single Bitrate: 500kbps and video format :h265_nvenc with ffmpeg extension options.

• for h265_nvenc supports http, rtmp input, but not support udp multicast input.

• Option 3: Multiple Bitrates: 500kbps, 1200kbps, 3000kbps and video format :h264_nvenc.

• for h264_nvenc supports udp, http and rtmp input link.

• Option 4: Multiple Bitrates: 500kbps, 1200kbps, 3000kbps and video format :h265_nvenc.

• for h265_nvenc supports http, rtmp input, but not support udp multicast input.

Intel examples:

• same as Nvidia setting except video format by h264_qsv.

Logo watermark channel:

• Click Edit more options of one channel and select Constant Bitrate (External transccoder) as below:

  

• Click Save button.

• Add transcoder_path=ffmpeg -i logo.png -filter_complex 'overlay=10:10' in ezserver_config.txt.

• restart ezserver

• Streaming URL: http://192.168.0.10:8000/getlink?username=test:password=1234:type=hls

CPU Transcoding:

Using FFmpeg transcoding input streams to H264/H265 format with multiple bitrate for Apple HLS streaming. 

Channel Input:

• Add UDP, HTTP or RTMP input Links into Channels

Add Channels	Select the 2nd network card for multicast input (optional)

Channel Output:
