Original commit message from CVS:
bugfixing:
- Fix for bug 93479
- Fix for bug 103659
- Did not set interleaved/non-interleaved correctly
- Changed g_print to DEBUG to disable unwanted output
Alsa is still not really useful. Missing is for example:
- Support for Relinking in paused state (when going to next song in gst-player)
- A bug when using gst-launch filesrc ! spider ! alsasink
- Support for events
- Padtemplates exporting proper caps
- general cleanliness
K, back to work ;)
