Before we just merged everything in pretty much random ways ad-hoc instead of keeping state properly. In 0.10 that was how it worked, but in 1.x the tag events sent should always reflect the latest state and replace any previous tags. So save the upstream (stream) tags, and save the tags set by the decoder subclass with merge mode, and then update the merged tags whenever either of those two changes. This slightly changes the behaviour of gst_video_decoder_merge_tags() in case it is called multiple times, since now any call replaces the previously-set tags. However, it leads to much more predictable outcomes, and also we are not aware of any subclass which sets this multiple times and expects all the tags set to be merged. If more complex tag merging scenarios are required, we'll have to add a new vfunc for that or the subclass has to intercept the upstream tags itself and send merged tags itself. https://bugzilla.gnome.org/show_bug.cgi?id=679768 |
