I have greatly simplified it to understand how I am trying to use avscale, as it is done in different threads using buffers to use other ARM cores. avcodec_send_packet(pCdcCtxInp, pPktInp); avcodec_receive_frame(pCdcCtxInp, pFrm); pFrm->pts = av_rescale_q(pPktInp->pts, pFmtCtxInp->streams[0]->time_base, pCdcCtxInp->time_base); avcodec_send_frame(pCdcCtxOut, pFrm); avcodec_receive_packet(pCdcCtxOut, pPktOut); pPktOut->pts = av_rescale_q(pFrm->pts, pCdcCtxInp->time_base, pCdcCtxOut->time_base); pPktOut->dts = pPktOut->pts;
