Does minisatip forward PMT pid?

Post by a19a »

Hi,
I am trying to record the PMT pid with

curl -s -m 3 -o video.ts "http://vuzero:8080/?src=1&freq=11766&sr ... 17,18,1101"

but the resulting .ts file does not contain the PMT pid (1101).

If I record the PCR pid (501) and the PMT pid, then the PMT is included in the ts file.

Could you help me please?

minisatip running on Vu+ (OpenViX) with minisatip_mips_gigablue_dvbcsa binary from this site.

Hi,
AFAIK this is by design, but can you explain why you need it in a record.

Yes, I want to record all the pids from a transponder.

Setting pids=8192 or pids=all in the url doesn't work, so I need to record the PMT to read the other PIDs.

How can I do that?

Thanks

Hi,
then you can add the pmt pids to the URL.

I try to explain.
I want to record all the transponder's pids.
Since on Enigma2 there is a limitation that prevents to use ioctl DMX SET PES FILTER (you can't used pids=8192), I need to read the PAT to get the PMT pids.

Then with PMT pids I can get the video, audio, teletext pids ecc. that I want to include in the url's parameter pids.

Here is the problem.

If I try to record from minisatip only with pids=0,1101 (0 = PAT, 1101 = one of the PMT pids of the transponder), then I get only the PAT pid in the .ts file, not the PMT pid!

So I can never read what are the other pids.

Could you fix that?

Thanks.

I think there are couple of requests for this feature. I could try to implement it by adding a pid filter for all the pids from the PMT.

Please do it!

I make an example to explain this strange behavior

Channel: RAI 1 HD (Hotbird 13E)

I record the stream asking for these PIDs: PAT (0), CAT (1), NIT (16), SDT/BAT (17), EIT (18), TDT/TOT (20), PMT (1101)

curl -m 20 -o video.ts "http://vuzero:8080/?src=1&freq=11766&sr ... 18,20,1101"

I check the recorded TS file with tsanalyze (from TSDuck)

tsanalyze --normalized video.ts

And I find in the stream the PID I requested but I can't read in the PMT the other PIDs values (video, audio, subtitles, ecm etc.)!

service:id=3401:tsid=5200:orignetwid=318:access=clear:pids=1:clearpids=1:scrambledpids=0:packets=0:bitrate=0:bitrate204=0:servtype=1:pmtpid=1101:pidlist=1101:provider=Rai:name=Rai 1 HD

pidlist lists only the PMT pid! Not the video, audio etc.

If I request the PMT I don't want to record the video, audio etc., but the PMT should list all the other PIDs values for the service!

Thanks!

Hi,
can you also post the minisatip start parameters you use.
