How to encode and decode image stream frame by frame

[Sean Scheideman]

I am trying to create a video streaming application, where I receive image frames from a usb camera, then encode them using H264. Then I send them to a server and decode them. 

Currently I am pushing frames into a H264 transcoder, then pulling the encoded frames and sending them to the the server. On the server side I push the encoded frames into the decoder and the try to pull, but this fails. 

I am wondering if I am doing this the right way and if this use case is supported? I see there is a previous post from 6/12/13: Decoding with push pull, where a PullPushDecoder sample is referenced, but there is no PullPushDecoder sample for the current version.

Attached are my encoding and decoding implementations. The server is a cpp app and the client is a C# app.

Thanks,

Hi Sean,

On the decoding side likely you need to call Push multiple times before you can get something out of Pull.

Also you must Push whole access units as shown in this example:

Thanks! Not pushing multiple times was the issue.
