Hi,
Is ca_set_pmt() from section 8.4.3.4 of EN50221 spec?
It looks like the offset is wrong for fetching ES length. I did some
modifications do dst_ca.c aswell. Aslo, the offset for fetching CA
descriptor (checking for 0x09) looks like wrong offset to me. The
relevant code for the additional debug info below is;
buf_offset += 1;// hw_offset += 1;
for (i = buf_offset; i < length; i++) {
// dprintk("%s: Stream Header ", __FUNCTION__);
count = copy_string(hw_buffer->msg, p_ca_message->msg,
hw_offset, buf_offset, 5);
modify_4_bits(hw_buffer->msg, (hw_offset + 3));
hw_offset += 5, buf_offset += 5, i += 4;
debug_string(hw_buffer->msg, hw_offset, (hw_offset - 5));
dprintk("%s: buf_offset-2
[p_ca_message->msg[buf_offset-2]]=%02x
[%02x]\n",__FUNCTION__,buf_offset-2, p_ca_message->msg[buf_offset-2]);
dprintk("%s: buf_offset-1
[p_ca_message->msg[buf_offset-1]]=%02x
[%02x]\n",__FUNCTION__,buf_offset-1, p_ca_message->msg[buf_offset-1]);
dprintk("%s: ES Info length bytes = [%02x %02x]\n",
__FUNCTION__, p_ca_message->msg[buf_offset - 1],
p_ca_message->msg[buf_offset]);
es_info_length = 0;
es_info_length = p_ca_message->msg[buf_offset-2] & 0x0f;
es_info_length <<= 8;
es_info_length |= p_ca_message->msg[buf_offset-1];
// es_info_length = ((es_info_length |
(p_ca_message->msg[buf_offset - 1] & 0x0f)) << 8) |
p_ca_message->msg[buf_offset];
dprintk("%s: ES info length=[%02x]\n", __FUNCTION__,
es_info_length);
if (es_info_length) {
dprintk("%s: buf_offset+1
[p_ca_message->msg[buf_offset+1]]=%02x
[%02x]\n",__FUNCTION__,buf_offset+1,p_ca_message->msg[buf_offset+1]);
dprintk("%s: buf_offset+2
[p_ca_message->msg[buf_offset+2]]=%02x
[%02x]\n",__FUNCTION__,buf_offset+2,p_ca_message->msg[buf_offset+2]);
dprintk("%s: buf_offset+2
[p_ca_message->msg[buf_offset+3]]=%02x
[%02x]\n",__FUNCTION__,buf_offset+3,p_ca_message->msg[buf_offset+3]);
// copy descriptors @ STREAM level
if (p_ca_message->msg[buf_offset + 2] == 0x09)
{ // Copy CA descriptor only
copy_string(hw_buffer->msg,
p_ca_message->msg, hw_offset, buf_offset, (es_info_length - 1));
dprintk("%s: Descriptors @ STREAM
level...!!! \n", __FUNCTION__);
}
}
}
