atom_trak_tx3g_update_dimension:
- not sure why height is multiplied by 0.15; this doesn't seem right (although
the dimensions are ignored by all players I tested this with)
atom_trak_set_subtitle_commons:
- subtitle track should have alternate group set; for now set it to 2 for all
subtitles (all other track have zero).
- layer should be above video, which has layer 0.
gst_qt_mux_prepare_tx3g_buffer:
- tx3g buffer should not be null terminated. use strnlen to get actual length
- buffer duration must be set manually. gst_buffer_copy_into doesn't copy
duration when length differs (seriously though, that's not very intuitive)
gst_qt_mux_add_buffer:
- should not compute DTS for sparse streams, as the gaps are handled later
using empty buffer
gst_qt_mux_request_new_pad:
- gst_collect_pads_add_pad should be called with lock = FALSE for sparse
streams, otherwise the pipeline stalls waiting for subtitle buffer that might
not come
