Re: Problems of Pinnacle PCTV Hybrid pro stick in linux
Hello Mauro and thanks for your sentences But: 1- For such experienced programmer as you, it is obvious from http://daftar.minidns.net/pctv/problem.html#problem2 , that when no any software could scan the channels, thus at least one important problem is in the kernel side, isn't it? If the problems are only in the userspace, at least one of many good softwares such as mentioned here: http://daftar.minidns.net/pctv/problem.html#problem1 could find the channels during scanning, aren't they? 2- you mentioned most of the comments and logs there provide not much help, i can provide any other help and comment and logs and tests of new changes in driver sources that you want, as i did about 12 days ago for Devin Heitmueller during a chat session in #linux-tv of irc.freenode.net. 3- you mentioned some about my performance complaints, but if you read this part of my writings: http://daftar.minidns.net/pctv/problem.html#c1 you can find the power of my testing hardware is reasonably very very higher than needed by tv showing applications, and the Nvidia-G9500-GT graphic card is more famous than we can relate the problems to its miss functioning, isn't it? 4- i inserted the scan result of another DVB-stick that i had, here: http://daftar.minidns.net/pctv/channels.conf for you , but i had not that DVB-stick now for testing again. it had the afatech-9015 chip set and could find my all 25 digital channel in any linux box by any here: http://daftar.minidns.net/pctv/problem.html#problem1 mentioned software. The only problem with that afatech based DVB was 2 : it could not play the sounds of digital channels except one of digital-TV channels i explained about it here: http://daftar.minidns.net/pctv/problem.html#p-h and here: http://daftar.minidns.net/pctv/problem.html#p-d and here: http://daftar.minidns.net/pctv/problem.html#p-e and here: http://daftar.minidns.net/pctv/problem.html#p-g , any second problem: it was not the analog TV capable. 5- and again the above mentioned paragraph (4) prove that most of problems is in the kernel space not userspace, because that afatech based DVB-stick could find all 25 digital channels during scan and play the by all of mentioned software, and only one of problems is the same as Pinnacle's one: the problem of sounds of that 13 digital tv channel. At end i again tell that, i am in the #linux-tv chat room as dast53 for speaking to solving those problems.

As I told you before, you're mixing clearly userspace issues or limitations with kernel-related ones. For example, there's nothing we can do at driver level to make kaffeine to perform better when decoding an MPEG-2 stream at full screen mode. This is probably either a performance issue with your GPU card or it is just that you're using a software decoder for it, on a slow CPU. Some applications allow, with a few GPU types, to run the MPEG-2 decoder inside the GPU. Yet, there's one relevant information there: 3- And even with kaffeine, the only way that i could watch some TV, was in this manner: Before this DVB-stick i inserted another DVB-USB stick in another linux computer and scan the channels with kaffeine and after finding the channels, quit the kaffeine and copy its database files ( $HOME/.kde/share/apps/kaffeine/* ) into the testing computer for pinnacle DVB-USB hybrid stick. After that copying, i could run kaffeine on the pinnacle DVB and without scanning, thus i had a table of channels and in its main window and when i clicked on a channel, that channel was shown. You mentioned that you did another dvb stick worked, but on another computer. Why such dvb stick didn't work at the computer you tested your Pinnacle device? Also, does the working stick is capable of getting the dvb channels using the scan tool provided at http://linuxtv.org/hg/dvb-apps? If so, please provide us the dmesg produced with the working card and the scan results (with -v, in order to put dvb scan into verbose mode), and the same info with the broken card.

We all are volunteers, and, while we spend some of our spare time to help people, we expect that the people to be nice and answer with technical information that will allow us to help,. http://daftar.minidns.net/pctv/problem.html#problem2 , that when no any software could scan the channels, thus at least one important problem is in the kernel side, isn't it? You told you tested it with two cards, having different results. Without the debug logs from both cards, there's no way to identify what's happening. If the problems are only in the userspace, at least one of many good softwares such as mentioned here: http://daftar.minidns.net/pctv/problem.html#problem1 could find the channels during scanning, aren't they? No. The scan procedure happens partially on userspace and partially on kernelspace. It is userspace task to decode the MPEG-TS and seek for for the Program Identifiers. 2- you mentioned most of the comments and logs there provide not much help, i can provide any other help and comment and logs and tests of new changes in driver sources that you want, as i did about 12 days ago for Devin Heitmueller during a chat session in #linux-tv of irc.freenode.net. Ok. Then please provide the logs for the both cards, showing what happens during the scan. We need scan -v log and the kernel logs (the command to get it is: dmesg). Please enable frontend, em28xx and af9015 debug logs, for us to know what the kernel is doing. 3- you mentioned some about my performance complaints, but if you read this part of my writings: http://daftar.minidns.net/pctv/problem.html#c1 you can find the power of my testing hardware is reasonably very very higher than needed by tv showing applications, and the Nvidia-G9500-GT graphic card is more famous than we can relate the problems to its miss functioning, isn't it? It doesn't matter what Nvidia card you're using. The more expensive process is the MPEG decoding. If that happens on userspace, it is your CPU that will be used. HD streams require too much CPU. With the right software and the right video board driver, this task could be send to the Graphics card (GPU), by using an API (like vdpau), but not all software supports, and it requires a GPU-accelerated codec for the video standard (typically, mpeg2). I'm not sure if Kaffeine currently offers GPU-accelerated mpeg2 codec, and if the nouveau or the Nvidia proprietary driver is compatible with Kaffeine's GPU's codecs. 4- i inserted the scan result of another DVB-stick that i had, here: http://daftar.minidns.net/pctv/channels.conf for you , but i had not that DVB-stick now for testing again. it had the afatech-9015 chip set and could find my all 25 digital channel in any linux box by any here: http://daftar.minidns.net/pctv/problem.html#problem1 mentioned software. It is interesting to see the logs for the af9015 device, and see what is it doing different than the Pinnacle one. The only problem with that afatech based DVB was 2 : it could not play the sounds of digital channels except one of digital-TV channels i explained about it here: http://daftar.minidns.net/pctv/problem.html#p-h and here: http://daftar.minidns.net/pctv/problem.html#p-d and here: http://daftar.minidns.net/pctv/problem.html#p-e and here: http://daftar.minidns.net/pctv/problem.html#p-g , From your descriptions, it seems that the program identifiers sent by the TV stations are wrong, or the userspace application is getting it wrong. Basically, each MPEG-TS stream has several PID's. each of them can have an audio or a video stream (there are also other types, but those two are the rellevant ones). The video and audio stream should be associated, otherwise, you won't be able to hear audio. There is another alternative: eventually, your country is using an audio codec that it is currently unsupported (or it requires you to install one additional libarary and re-compile your application). any second problem: it was not the analog TV capable. 5- and again the above mentioned paragraph (4) prove that most of problems is in the kernel space not userspace, because that afatech based DVB-stick could find all 25 digital channels during scan and play the by all of mentioned software, and only one of problems is the same as Pinnacle's one: the problem of sounds of that 13 digital tv channel. Probably, but hard to know without having both logs to compare. At end i again tell that, i am in the #linux-tv chat room as dast53 for speaking to solving those problems. I'm traveling abroad this entire week, and next week I'll be handling the pending work. Also, as the merge window will probably be opened next week, I'll be busy submitting the patches we have upstream. So,

( i thought that the experienced programmer is a good adjective. ) i provided some of logs you told: the log of dmesg during inserting the Pinnacle's DVB-Stick and output of scan -v and some others here: http://daftar.minidns.net/pctv/some-log1.zip . This file has a file named readme-first.txt containing description of its contents. i will try to provide again the afatech-9015 based DVB-stick to find the logs you want about it.
