I'm running into an issue where setting the bitrate for a 1280x720 video to 4mbps is seeemingly ignored. The video encodes at most ~1.7mbps. To be sure this is not some issue with my code I used raspivid to test this and it gives about the same result. Where I set the bitrate to 4 or 10mbps but it n...

I'm using the HW encode (vc.ril.image_encode) to produce a jpeg file. I can do this just fine with RGB24 and RGBA. After some testing and getting familiar with mmal I wanted to use YUV data as the input but I'm having an issue with getting YUV(I420) to work. Does the input port accept I420 as an acc...

I solved my own problem and just in case anyone needs the solution. I needed to send a buffer to the output port before I send the input buffer. ... * get buffer from the output ports pool * send buffer * get buffer from the input ports pool * send buffer * wait for input port callback to complete *...

I'm trying to pass a bitmap rgb image data buffer to the encoder component that will compress the data to jpeg. This does not rely on the camera component and is only the encoder component. I have these steps... * create the encoder component * set the input port format to the width, height, and enc...
