Description
hello I am currently using version 1.5.3,avformat_find_stream_info () will execute for about 2 seconds.So i need to close avformat_find_stream_info().If I call grabber.start (false), I will get an error message：Did not find a video or audio stream inside "java.io.BufferedInputStream@3b424c84" for videoStream == -1 and audioStream == 2147483647.
I already know the information of some video sources, but I do n’t know how to use the information I know to make the program run normally after closing avformat_open_input ()。
Should I set the information I know here?
grabber.setVideoOption("vcodec", "copy"); grabber.setFormat("mpeg"); grabber.setPixelFormat(avutil.AV_PIX_FMT_YUV420P); grabber.setVideoCodec(avcodec.AV_CODEC_ID_H264); grabber.setAudioStream(Integer.MAX_VALUE); grabber.setFrameRate(25); grabber.setImageWidth(1280); grabber.setImageHeight(720);
If yes, what properties do I need to set to allow the program to execute normally? If not, where do I need to set up some video information I know?
I'm helpless about this, can you give me some help? thank you very much!
