   mchehab: #define DVB_USB_STREAM_BULK(endpoint_, count_, size_) { \
   <br> .type = USB_BULK, \
   <br> .count = count_, \
   <br> .endpoint = endpoint_, \
   <br> .u = { \
   <br> .bulk = { \

   <br> } \
   <br> basically, it does USB bulk transfers (so, no warranty about a continuous transfer rate)
   <br> it uses 10 buffers of 4096 bytes
   <br> actually, it allocates 10 buffers of 4096 bytes
   <br> that doesn't necessarily uses all of those
   <br> as the hardware can send URBs with a smaller burst transfer
   <br> if you want to know how many bytes, you'll need to either sniff the USB bus or to add some printks at the Kernel's logic
   funman: <u>mchehab</u>: why would I get overflow for some sat streams and not others ?
   kierank: " read failed: Value too large for defined data type"
   funman: <u>kierank</u>: yes that's EOVERFLOW
   mchehab: probably due to their bitrate
   kierank: it doesn't seem dependent on whether the bitrate is high or low
   mchehab: hard to tell, as the DMA itself depends on the hardware
   <br> (or, typically, a firmware - as most devices either use a RISC or a FPGA)
   iridium_: is there a reason why most headers required for building dvb drivers reside in drivers/media/dvb-core/ and not somewhere beneath include/? this makes building out of tree drivers against distro kernels quite painful
   zomaar: So I spent an entire day getting this thing working and in the end the problems were caused by nouveau and some hardware renderer not working
   <br> I mean hd pau or whatever
   <br> And I mean, Kaffeine crashes on any video output, so does Xine
   <br> And VLC doesn' work until I select another video output mode. Great.
   <br> But today I had television.
   <br> But not for long, I don't know what changed but for the first time nothing works anymore.
   <br> Scans don't work (dvb_read_segment error)
   <br> dvb_read_sections
   <br> While it does have signal after that it crashes.
   <br> ERROR    dvb_read_sections: no data read on section filter
   <br> And I changed nothing to my system. Did a hard reboot (power off)
   <br> Still the same, suddenly it stopped working.
   <br> Did I break it by using the wrong drivers?
   <br> All I know is that I see no chance of this returning to normal because there is nothing I did?
   <br> Earlier in the same boot it still worked :-/.
   <br> I don't know if dmesg output changed.
