| Bugs | ||||
| x | Interaction between standards organizations (ETSI, ITU, ISO, ...) and also between standards itself sometimes is very complex, especially when standards are enhanced or collide with other drafts. So bugs are very likely (also programming bugs...). Due to missing or proper test streams, some features are implemented without possible real life testing... So please report any bug or odd behavior and also check latest source from cvs. |
The feature list reflects the status of the
CVS. This list may not be
complete...
Some features do not work using DVB-API 1.
