I'm passing the following pipeline string to the gst_rtsp_media_factory_set_launch function to create an rtsp output:
souphttpsrc location=[some https url.m3u8] ! decodebin ! videoscale ! video/x-raw,width=1080,height=720 ! x264enc ! rtph264pay name=pay0 pt=96
So long as I set the height and width to match the original video, in this case 720 x 480, everything works. However if I actually try to change the size, it fails.
I get many errors from GST_DEBUG=2, but the first one is this:
0:00:08.560644403 63781 0x7ff24403ad20 ERROR vaapivideomemory gstvaapivideomemory.c:254:map_vaapi_memory: failed to make image current

The same pipeline works if I substitute videotestsrc as the source; additionally, oddly enough, I'm about 90% sure this worked on a different PC I no longer have access to.
