Internal fIrewire channel changer addon

Cc: Ticket locked: no


Hi, I am running the internal firewire changer on a SA4200HD, this works great but sometimes the box "missfires" and does not send anything on the firewire bus. If you reissue a request to that box it sends some data. Would it be possible to add a behaviour (disabled by default) but that could be enabled by the user in mythtv-setup / Input connections like this pseudo code: bool onChannelChange(ChannelChangeData?& d) {

int i = NUM_RETRIES; bool success = false;

while(i >= 0) {

sendChannelChangeRequest(d); if(isDataPresentOnFWBusFromBox(d.GUID)) {

success = true; break;


} return success;


This would be a nice value added as right now anytime there is a misfire and the recorder create a 0 byte length file, the backend crashes on commercial flagging or mythweb access (while trying to delete the 0byte file)
