Ok, this is the minimum case:
AVFormatContext *input;
AVPacket pkt;
AVFormatParameters ap;
input=av_alloc_format_context();
input->iformat=av_find_input_format("mpegts");
bio_buffer=(unsigned char *)malloc(bio_buffer_size); //=188
input->pb=av_alloc_put_byte(bio_buffer,bio_buffer_size,
0,this,linsys_read,NULL,NULL);
input->pb->is_streamed=1;
input->pb->max_packet_size=188;
input->flags|=AVFMT_NOFILE|AVFMT_FLAG_IGNIDX;
input->max_index_size=1024*50;
input->max_picture_buffer=1024*100;
memset(&ap, 0, sizeof(ap));
ap.prealloced_context=1;
int r=av_open_input_stream(&input,input->pb,"linsys",input->iformat,&ap);
r=av_find_stream_info(input);
while(!is_exiting()){
av_read_frame(input,pkt);
av_free_packet(pkt);
}
According to the Windows' Task Manager, the program occupies ~7Mb initially,
and ~8.6Mb after 5 min of work. The number, taskman shows, is not constant, it
changes every second, growing up or falling down, but overall trend is growing.

I have a success in reading data from a card and writing them to the stdout and
feeding ffmpeg.exe through the pipe.
The main cycle in my program is following.
uint8_t buf[10340];
int readed;
while(!is_exiting()){
readed=linsys_read(this,buf,10340); //pointer to this function is also
fwrite(buf,readed,1,stdout);
}
return 0;
d:\>main.exe > nul
gives that the program consumes less than 4.5Mb, and this number doesn't grow.
Now, feeding ffmpeg.exe
D:\>main.exe| ffmpeg.exe -y -f mpegts -i - a.mpg

Then taskman shows that main.exe occupies about 600Mb, and its occupation
quickly grows. ffmpeg occupies about 35 Mb and this number also grows.
Messages about mpeg1video are weird, as I know for sure, there is no MPEG1
Video in the stream.

Amounts were not huge per se, memory is leaking very slowly. This report from
the leak detector was for the very short time.
