Version history

OSCam history is accessible through Trac timeline at: https://git.streamboard.tv/common/oscam/-/commits/master

Repositories

GIT repository: git clone https://git.streamboard.tv/common/oscam.git oscam

Building OSCam from source

For more information and examples on using the build system, please see README.build and README.config files.

Building OScam for different CPUs (cross-compilation)

First you need to install the target CPU toolchain. Already built toolchains for various architectures can be downloaded from:

https://git.streamboard.tv/common/oscam/-/wikis/CrossCompiling

In order to cross compile OSCam you need to set CROSS variable when running make. For example to compile for SH4 architecture you need to run: make CROSS=sh4-linux- or if your cross compilers are not in your PATH - make CROSS=/opt/STM/STLinux-2.3/devkit/sh4/bin/sh4-linux-.

Dependencies

OSCam by default do not depend on external libraries except when compilation with SSL is requested. In that case openssl (libcrypto) library must be installed.

OSCam supports building with the following external dependencies:

  • libcrypto (libssl) - 'make USE_LIBCRYPTO=1'
  • libusb - 'make USE_LIBUSB=1'
  • PCSC - 'make USE_PCSC=1'
  • SH4 STAPI support - 'make USE_STAPI=1'
  • SH4 STAPI5 support - 'make USE_STAPI5=1'
  • Coolapi support - 'make USE_COOLAPI=1'
  • AZBOX support - 'make USE_AZBOX=1'

For STAPI support you need to download liboscam_stapi.a library and place it in stapi directory under oscam/ root dir. liboscam_stapi.a can be downloaded from: https://board.streamboard.tv

For STAPI5 support you need to download liboscam_stapi5.a library and place it in stapi directory under oscam/ root dir. liboscam_stapi5.a can be downloaded from: https://board.streamboard.tv

For more information and examples on using the build system, run make help.

Help and Support

man pages and configuration examples are in Distribution/doc directory.

oscam-patched's Issues

PowerVu not descrambling

EMM and ECM keys match, no issue in logs. But no image/sound appears in some transponders.
Currently in EMU = 801. Platform: Linux PC.

What info do I need to send for troubleshooting?
Thank you

aarch64

How does DES decoding work for you in PowerVu (1W/TV5, 5E/SIS, 5E/MTN, 16E/SNAI, 16E/IPPICA) in aarch64 (DM One-Two)?

CW shows OK (sometimes ECM Checksum error), but no picture.

With CSA in PowerVu (9E/AFN) , the picture is fine.

Revision number

Hi @nautilus7,
at this time we have (as workaroud) a virtual revison number counting in oscam official. See: https://github.com/oscam-emu/oscam-patched/blob/master/config.sh#L713-L718
This breaks now, because oscam-patched does not have the same commit count as the orginal repo.

Do you have an idea how to manage this? Short resolution is to change the offset here + 2 (and increment it with every additional commit in oscam-patched that oscam official does not have)

But the main issue came from oscam official. There we have no pipeline setup until now to use another revision number generation approach. Maybe we should create an issue in gitlab and discuss the oscam way there...

oscam-emu will not allow remote client to AU keys

Even with AU enabled I cannot get a remote client (oscam using cccam protocol) to update the ECM keys in oscam-emu.
It seems the EMM filters (UAs) are not sent.
From the client log

(dvbapi) Demuxer 0 matching reader  XxxxxxX  against available emmpids -> START!                              
(reader) XxxxxxX  [cccam] EMM: reader 0E00 match since emmpid has no provid -> SEND!                          
(dvbapi) Demuxer 0 cardsystem for emm filter for caid 0E00 of reader  XxxxxxX  not found                      
(dvbapi) Demuxer 0 matching reader  XxxxxxX  against available emmpids -> DONE!                               
(dvbapi) Demuxer 0 handles 0 emm filters                                                                      
(dvbapi) Demuxer 0 filter1[0] = 80, filter mask[0] = F0, flt&mask = 80 , buffer[0] = 80, buffer[0] & mask = 80

Is it possible to fix this?

AU works fine on the local server.
If the correct ECM keys are in the SoftCam.key file of the server then the client gets a picture.
It is just the EMM keys AU'ing that is the problem.
