Decoding H.264 UDP stream Example

[mlbderby998]

Hey I am trying to evaluate using the Intel Media SDK to decode a live UDP H.264 video stream from a hardware video encoder with a focus on low latency (~200ms or lower). I have been looking at the samples but all of the decoder samples only seem to support an input of a video file. Is there way to configure one of the samples to decode a UDP stream or is there another sample project I can use. I am trying to minimize the time required to get a working demo in order to measure some preliminary data on how this decoder performs against some of the other decoders out there.  Thank you for your help.

The easiest way is to inherit from their file class, and use that as the input/output mechanism. This minimises the changes to the Intel code, but also allows you to source the data from a non file source. Thats how I hooked it up to our frame grabber and custom file mechanism.

Hi,

The Media SDK product does not provide samples for all possible integration points.But we have written some white papers and tutorials that you may find interesting in your efforts.

FFmpeg supports a wide range of mux/demux features and codecs that Media SDK does not cover. FFmpeg also has support for UDP streaming. For an example on how to integrate Media SDK with FFmpeg, check out the FFmpeg integration section part of the Media SDK tutorial, here:

Hi Nguyen,

Here is the link for the tutorial package, release 0.0.4 has the ffmpeg integration Petter mentioned.

For the website, we have 3 main sources for media SDK historically, all of there are based on the same API code base while a little bit difference among these:

https://software.intel.com/en-us/media-sdk : this is Media SDK for Windows and Media SDK for Embedded Linux(Yocto)

https://software.intel.com/en-us/intel-media-server-studio : this version is used to support Intel server platform(CentOS, Ubuntu) on Linux.

https://github.com/Intel-Media-SDK/MediaSDK : this is our open source project which support Linux with source code.

Our tutorial code is to enable user to start programming and this is why Petter recommend.

Except to use Media SDK directly, you can also use major media frameworks, FFmpeg and G-Streamer, you can find the installation guide here:
