Hi Carl, > My parameters are as follows: > (AVCodecContext*) pCodecContext->pix_fmt = AV_PIX_FMT_YUV420P; > AV_PIX_FMT_YUV420P is the default parameter when code_id is AV_CODEC_ID_HEVC > and it is one of raw format. So I think the order of frame I get from > "avcodec_receive_frame(pCodecContext, pFrame);" is PTS and when I try to > display the frame recieved, it can display properly. But its frame->pts is > still not incremental. > I tried to set the pix_fmt to AV_PIX_FMT_NV12, but it doesn't work. The > pix_fmt still change back to AV_PIX_FMT_YUV420P. > Do I set the wrong pix_fmt so that the it doesn't decode to the specific raw > format? I am not familiar with these formats. What I do in this cases is * take deeper look into the examples [1] * debug frame by frame * create a test case using the `ffprobe -show_packets` command on an expected output file and compare them to the packets my code is producing
I am not a libav expert so this is how far I can go. Hope it helps.
