Hi,

I went through the mediastream2 code, where, the following is given,

static int enc_set_br(MSFilter *f, void *arg){
        EncState *s=(EncState*)f->data;
        bool_t snow=s->codec==CODEC_ID_SNOW;
        s->maxbr=*(int*)arg;
        if (s->maxbr>=1024000 && s->codec!=CODEC_ID_H263P){
                s->vsize.width = MS_VIDEO_SIZE_SVGA_W;
                s->vsize.height = MS_VIDEO_SIZE_SVGA_H;
                s->fps=17;
        }else if (s->maxbr>=800000 && s->codec!=CODEC_ID_H263P){
                s->vsize.width = MS_VIDEO_SIZE_VGA_W;
                s->vsize.height = MS_VIDEO_SIZE_VGA_H;
                s->fps=17;
        }else if (s->maxbr>=512000){
                s->vsize.width=MS_VIDEO_SIZE_CIF_W;
                s->vsize.height=MS_VIDEO_SIZE_CIF_H;
                s->fps=17;
        }else if (s->maxbr>=256000){
                s->vsize.width=MS_VIDEO_SIZE_CIF_W;
                s->vsize.height=MS_VIDEO_SIZE_CIF_H;
                s->fps=10;
                s->qmin=3;
        }else if (s->maxbr>=128000){
                s->vsize.width=MS_VIDEO_SIZE_QCIF_W;
                s->vsize.height=MS_VIDEO_SIZE_QCIF_H;
                s->fps=10;
                s->qmin=3;
        }else if (s->maxbr>=64000){
                s->vsize.width=MS_VIDEO_SIZE_QCIF_W;
                s->vsize.height=MS_VIDEO_SIZE_QCIF_H;
                s->fps=snow ? 7 : 5;
                s->qmin=snow ? 4 : 5;
 }else{
                s->vsize.width=MS_VIDEO_SIZE_QCIF_W;
                s->vsize.height=MS_VIDEO_SIZE_QCIF_H;
                s->fps=5;
                s->qmin=5;
        }
        if (s->av_context.codec!=NULL){
                /*apply new settings dynamically*/
                ms_filter_lock(f);
                enc_postprocess(f);
                enc_preprocess(f);
                ms_filter_unlock(f);
        }

where, mac fps is given as 17, my doubt is whether linphone will support 25 fps.
