Android H264 Decode Non-existing Pps 0 Referenced

In Android JNI, using ffmpeg with libx264 use below codes to encode and decode raw rgb data!. I should use swscale to convert rgb565 to yuv420p as required by H.264. But not clear

Solution 1:

In your decode_inline() method, right after specifying the size, here are some codec parameters that you can play with to get the higher quality. I filled in the values to get you started:

c->gop_size = 10;                                       // one intra frame every ten frames
c->max_b_frames = 1;                                    // max # of b-frames 
c->keyint_min = 1;                                      // min GOP size
c->i_quant_factor = (float)0.71;                        // qscale factor between P and I frames
c->b_frame_strategy = 20;                               
c->refs = 4;                                            // number of reference frames
c->trellis = 1;                                         // trellis RD Quantization
c->qcompress = (float)0.8;                              
c->qmin = 20;                                           // min quantizer
c->qmax = 51;                                           // max quantizer
c->max_qdiff = 4;                                       // max quantizer difference between frames

Let me know how it goes.
