[Libav-user] MOV and custom IO

I've written some code to change the video container from MOV to MPEG-TS using ffmpeg API successfully. I'm using physical files.
Now i have to change my input from file to custom IO. I changed the code for use custom IO with a callback (read_packet_callback) to feed ffmpeg.
fmtCtx = avformat_alloc_context();
iformat = av_find_input_format(input_fmt);
ibuffer = (unsigned char *) av_malloc(BUF_SIZE + FF_INPUT_BUFFER_PADDING_SIZE)
fmtCtx->pb = avio_alloc_context(ibuffer,
avformat_open_input(&fmtCtx, "in-memory", iformat, NULL)
When i run the code the function avformat_open_input blocks, it reads N chunks of data but don't terminate with or without error. This happens with MOV format. I've tried using MPEG-TS format and this code runs successfully.
There's a special trick for MOV format? Has anyone encountered this problem?
