Timeline does not start when trying to encode with a video/quicktime container #39

Closed lubosz closed 11 years ago

lubosz commented 11 years ago

This script shows that the timeline does not start for quicktime, but for matroska. Same codecs.

Yes, that's something to add to integration tests, fairly simple, for now we only test encoding with an ogg profile.

These is a excerpt of the log (i deleted duplicate errors) from the integration test suite

Lines like these confirm this bug: ges/integration.c:432:E:render:test_effect_render_to_aac_h264_quicktime_mp3_h264_mov:0: (after this point) Test timeout expired

Do you also encounter them?

Yes we do, working on fixing these one error at a time :)

This can be closed, I was using a wrong caps constructor (or it was fixed somewhere else in gst)

This works now:
