I’m using the hardware video encoder to encode h264 video. My source is YUV420, with seperate Y U and V planes.
The resolution of this video is 1280x720, meaning my buffer sizes should be 921600 for y, and 230400 for U and V.
The resultant (encoded) video doesn’t look right. the Y channel seems to be just fine, but the colors are off. There’s a big green bar at the bottom of the video that seems to indicate my chroma samples aren’t correct.
When i look at the buffers that are mapped for my output planes, the U and V buffers are 276480 bytes wide, which is 1.2 times the size that I expect. I think that the extra space at the end of the buffer means that I’ve got my formatting wrong.
Have I missed something? I’m having trouble understanding why these buffers aren’t the size that I expect.
Thanks for any Insight.
