Tvheadend

The log is incomplete. Please, subscribe for one channel for 60 seconds when the CAM becomes ready.

Could you retest with this change?

I pushed some minor changes to the master repository, but I don't think that it will fix the dead-after-capmt problem.

I need to look what the previous code does for your hw. Please, do this for working version of tvh:

Obtain PID of freshly started tvheadend:

$ ps ax | grep tvheadend
19583 pts/0    Rl+    0:04 ./build.linux/tvheadend ....

Obtain file descriptor number for /dev/dvb/adapter0/ca0 using tvh's PID 19583:

$ ls -la /proc/19583/fd | grep /ca0
lrwx------. 1 perex perex 64 17. pro 18.22 27 -> /dev/dvb/adapter0/ca0
                                           ^^

So main PID for tvheadend is 19583 and file descriptor number for /dev/dvb/adapter0/ca0 is 27. Run strace (replace appropriate values with yours):

strace -f -tt -P /dev/dvb/adapter0/ca0 -e trace=write,read -e write=27 -e read=27 -p 19583 2> strace.txt

If CAM is ready, run streaming for one channel for 60 seconds (it must work). Then break strace (after 10 seconds after streaming).

Upload strace.txt, if it contains something like:

[pid 19056] read(26, "\0\1\200\2\1\0", 8192) = 6
 | 00000  00 01 80 02 01 00                                 ......           |
[pid 19056] write(26, "\0\1\240\1\1", 5) = 5
 | 00000  00 01 a0 01 01                                    .....            |
[pid 19056] read(26, 0x7ff1562ca810, 8192) = -1 EAGAIN (Resource temporarily unavailable)
[pid 19056] read(26, "\0\1\200\2\1\0", 8192) = 6
 | 00000  00 01 80 02 01 00                                 ......           |
[pid 19056] write(26, "\0\1\240\1\1", 5) = 5
 | 00000  00 01 a0 01 01                                    .....            |

Pls, retest with v4.3-811-ge06ffd87b (latest).

The last strace does not contains full hexadecimal dumps for read/write - update '-e write=' and '-e read=' numbers correctly. Please, tune same channel as in tvheadend.log (Animal Planet HD) - only this channel.

As I said on IRC, since last version I cant open more than 16 different channels using oscam (with oscam patched). Is now needed to increase DEMUX limit on tvheadend config? I'm not sure from which version this happens. Previously tvheadend when filling 16 channels by demux opened another demux of 16, etc.

Hi Pablo

Think you have commented wrong post, this is about hardware CAM

I checked capmt from dvb-apps (liben50221) and the new code, and it's identical now:

(first line is from dvb-apps, the second - upper hexa - from new tvh code).

I know that it's not big fun, but could you do new whole trace (working tvh) + tvh logs (new tvh) like:

for working tvh:

1) disable CAM - shutdown tvh
2) start tvh
3) run strace
4) enable CAM
5) play a channel (Animal Planet HD)
6) stop strace

for non-working tvh (same as you did before):

1) start tvh (enable CAM if it's not enabled)
2) play a channel (Animal Planet HD)
3) upload the log with traces
4) shutdown tvh
5) upload log

Pls, wait the instructions are not perfect.. It won't work.

Ok, here are much more simpler instructions, run this for both (working/non-working) tvh - immediately after tvh start:

strace -tt -f -P /dev/dvb/adapter0/ca0 -s 4096 -xx -p $(ps ax | grep tvheadend | grep -v grep | cut -d ' ' -f 1) 2> trace-working.txt

Try to watch 'Animal Planet HD'. Stop tvh and strace.

Upload both files here.

The traces in 'trace-working.txt' are a bit late. The -bad version is ok. Could you restart tvh and do strace on the one line? I need only updated 'trace-working.txt'.

Please, retest with the master. If it does not work, upload '--trace en50221' log for the 'bad' tvh, again.

Could you try to add CAID 5601 to the configuration / stream / CA stream filters with the action 'IGNORE' ?

Unfortunately no difference

Sorry, it works, thanks for all your help!

I fixed the CAID issue (you may remove the explicit filter now). I believe that your problem is completely fixed now.

Did update to the new version and did remove the filter and everything works! :D

Thank you for all your help and hope you have a good weekend / Christmas and a happy new year
