Q2) when i run "cat /dev/dvb/adapter0/dvr0 > ~/dvbs.ts" and the card is tuned to DVB-S channel with MPEG-2 video then i got playable (with mplayer) TS file, but when i do the same for DVB-S2 channel with H.264 video mplayer plays only the audio and reports: TS file format detected. VIDEO MPEG2(pid=767) AUDIO MPA(pid=768) NO SUBS (yet)! PROGRAM N. 0 MPEG: FATAL: EOF while searching for sequence header. Video: Cannot read properties. so how to dump correct TS file with H.264 video ? thank you! best wishes, konstantin On 10/14/07, Konstantin Dimitrov <kosio.dimitrov@xxxxxxxxx> wrote: > hello Manu, > > i have Technisat Skystar HD card with STB0899 revision C2L, so early > today i got your code from http://jusst.de/hg/multiproto and run some > tests. > > i'm using hacked szap from http://abraham.manu.googlepages.com/szap.c > with the patch from here: > > http://www.linuxtv.org/pipermail/linux-dvb/2007-October/021054.html > > and the following locktest.sh shell script: > > #!/bin/sh > i=0 > j=0 > while [[ $i -lt $4 ]] > do > i=$((i + 1)) > ./szap -t $3 -x $1 > if [[ $? -eq 1 ]] > then > echo "fail: $i" > j=$((j + 1)) > fi > sleep $2 > done > echo "succ: $((i - j)) | fail: $j" > > i run all tests on Astra 19.2E satellite with the following channels.conf: > > Pro7HD:12722:h:0:22000:255:259:10200 > NRJ:11538:v:0:22000:608:628:6908 > > for every test i do the following steps: > > 1. trim /var/log/debug, /var/log/syslog, /var/log/messages > 2. modprobe stb6100 verbose=5; modprobe stb0899 verbose=5; modprobe budget_ci > 3. run locktest.sh, e.g. for the DVB-S channel i run "locktest.sh NRJ > 5 0 20 > szap.out.nrj", which means: tune to channel NRJ, sleep for 5 > seconds between two consecutive tune tries, use DVB-S and do 20 tune > tries; for DVB-S2 i run "locktest.sh Pro7HD 5 2 20 > szap.out.pro7hd" > 4. rmmod budget_ci; rmmod stb0899; rmmod stb6100 > 5. save /var/log/debug, /var/log/syslog, /var/log/messages and > szap.out.$chan_name > 6. go to 1. > > i repeated the test many times and the results are similar. > > the attached "nrjhits.tar.gz" contains the logs for one of the DVB-S > tests, 16 successful locks out of 20, try 7, 8, 9 and 17 fail to lock, > some interesting things that i've noticed during the DVB-S test are: > - in 3 out of 5 runs of "locktest.sh NRJ 5 0 20" always exactly try 7, > 8, 9 and 17 fails to lock, so seems like same kind of pattern > - when run "locktest.sh NRJ 5 0 100", i got around 80 successful locks > out of 100, but when run "locktest.sh NRJ 45 0 100", i got around 95 > successful locks out of 100, so seems that increasing the sleep time > between two consecutive tune tries significantly increase the > successful lock rate > > during one of the DVB-S tests with "locktest.sh NRJ 5 0 20" i received > the following message "FE_DISEQC_SEND_BURST failed: Connection timed > out" and that test have only 9 successful locks out of 20, try 2, 3, > 4, 6, 7, 8, 9, 15, 16, 17 and 19 fails to lock, the attached > "nrjhits_diseqc.tar.gz" contains the logs from that test, because > maybe "FE_DISEQC_SEND_BURST failed: Connection timed out" is somehow > connected to the (un)successful lock rate. > > the attached "pro7hd.tar.gz" contains the logs for one of the DVB-S2 > tests, 18 successful locks out of 20, try 12 and 14 fail to lock, > increasing the sleep time between two consecutive tune tries with > DVB-S2 doesn't help and i always have around 90% successful locks. > > so, to summarize i got about 80% successful lock with DVB-S and 90% > successful locks with DVB-S2. > > i am open to help you with what i can, e.g. running more tests under > your instructions, etc. > > also i have some questions: > > Q1) here: > > http://linuxtv.org/pipermail/linux-dvb/2007-January/015585.html > > you are saying that revision C1L of STB0899 is faulty, fails to lock a > lot and we shouldn't buy cards with STB0899 revision C1L, but here: > > http://linuxtv.org/pipermail/linux-dvb/2007-October/021133.html > > you are saying that cards with C1L tune quiet fine and the lock > problems are only with revision C2L, so that confuses me a lot, could > you please clarify the situation with different revisions of STB0899 ? > > Q2) when i run " > > _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
