Negotiated Codec failed H264

[Carlos Antonio Perea Gómez]

Hi guys, 

I have the following issue:

I am running androidx86 on a vm, and I am testing a self-written application to stream video encoded with H264.

With a more generic codecs in the SetSendParameters i get VP8/9 negotiated. If I narrow down the request to H264 it fails to negotiate. 

I can see codec is installed:

12-10 16:30:30.618 12644 23027 I CPM.ConnectActivity: Codec info: Name OMX.google.h264.encoder, Encoder true, Supports [video/avc]

With generic request (including VP8, VP9):

With H.264 only request:
