What is SoftCSA?With
SoftCSA, Enigma2 acquires a native software decryption capability for channels with Algorithm 3 (CSA-ALT) Encryption. These channels cannot be decrypted by the hardware descrambling unit of the receivers and have previously had to be used via the StreamRelay detour to be handled in OSCam.
SoftCSA integrates decryption directly into Enigma2 – the encrypted transport stream is received, decrypted in software and seamlessly passed on to the decoder. The result: faster switching, better performance and full feature support.
Why does that make sense?- No StreamRelay Overhead: No more double HTTP connection
- Direct descrambling of the AV stream in the Enigma2 process
- Better performance on channel change and timeshift
- Less interruptions and more stable playback
- Full recording functionality
How to install?- Check your receiver's compatibility. Your box must be listed here (https://images.mynonpublic.com/openatv/build_status_devel76.html).
- Install the latest version of OpenATV 7.6.0 (https://www.opena.tv/app.php/atv_images) (or update to the latest stable version 7.6.0)
- Install manually OSCam Master from Secret-Feed (newest version with WITH_EXTENDED_CW):
wget --no-check-certificate -O - -q http://updates.mynonpublic.com/oea/feed | bash
opkg install oscam-master
- In case of problems with libdvbcsa Library please install it manually and repeat previous step:
opkg install libdvbcsa1
- Disable StreamRelay (if enabled)
- Select station in the channel list -> "Play the channel without StreamRelay"
- Rename/delete the file /etc/enigma2/whitelist_streamrelay if exist
- Delete [streamrelay] section in oscam.conf
- Customize OSCam Configuration. In the section [dvbapi] the oscam.conf please add:
pmt_mode = 6
extended_cw_api = 1
Alternatively via the OSCam WebIF under Config -> DVBApi.
- Use the Oscam-master as main softcam
- Success control. If the following entry appears in the OSCam log, everything is set up correctly:
2026/07/01 21:09:34 c (dvbapi) Client connected: 'Enigma2' (protocol version = 3)
