Which is it the value of pCodecCtx->codec_id that you pass to
avcodec_find_decoder()?

Hi,
Im trying to execute a example program given in ffmpeg folder ,
_1.1. Register all formats and codecs_
av_register_all();
avcodec_register_all();
avformat_network_init();
works fine
_1.2. Open video file_
char *drone_addr = "http://192.168.1.1:5555";;
AVFormatContext *pFormatCtx = NULL;
while(avformat_open_input(&pFormatCtx, drone_addr, NULL, NULL) != 0)
printf("Could not open the video file\nRetrying...\n");
works fine
_1.3. Display information_
// Retrieve stream information
avformat_find_stream_info(pFormatCtx, NULL);
// Dump information to standard output
av_dump_format(pFormatCtx, 0, drone_addr, 0);
works fine
_1.4. Find decoder _
// Get a pointer to the codec context for the video stream
// and find the decoder for the video stream
AVCodecContext *pCodecCtx;
AVCodec *pCodec;
pCodecCtx = pFormatCtx->streams[0]->codec;
pCodec = avcodec_find_decoder(pCodecCtx->codec_id);
the condition fails.. avcodec_find_decoder always fails.. any help
Thanks in advance
