I have some code that worked without issue up until now. When I pass a file
path into avformat_open_input I can create a pFormatCtx, but none of the
streams have any codec information associated with them, ie
pFormatCtx->streams[i]->codecpar is null. I assume that my codecs are not being
opened? I know that av_register_all() is deprecated, but otherwise
avformat_open_input doesn’t work. I am using 3.4.2 of ffmpeg. Any assistance is
appreciated.

av_register_all();
int error = avformat_open_input(&pFormatCtx, filePath, NULL, NULL);
if(error != 0){
char * errorString= (char*)malloc(AV_ERROR_MAX_STRING_SIZE);
(void) av_strerror(error, errorString, AV_ERROR_MAX_STRING_SIZE);
printf("%s\n", errorString);
status = K_CANT_OPEN_FILE; // Couldn't open file
return;
}
if(avformat_find_stream_info(pFormatCtx, NULL)<0){
status = K_NO_STREAM_INFO; //NO STREAM INFO
return;
}
videoStream = -1;
for(i = 0; i < pFormatCtx->nb_streams; i++){
AVStream * stream = pFormatCtx->streams[i];
if(pFormatCtx->streams[i]->codecpar->codec_type == AVMEDIA_TYPE_VIDEO)
{. // <—codecpar is NULL
videoStream=i;
break;
}
