thank you for your testing
patch https://github.com/jocover/jetson-ffmpeg/commit/e892195797ada3599a737265150559fbac8d0151
Unfortunately it just segfaults now:
Here is the backtrace from gdb:
(gdb) bt
Backtrace stopped: previous frame identical to this frame (corrupt stack?)
The patch provided here https://github.com/jocover/jetson-ffmpeg/commit/e892195797ada3599a737265150559fbac8d0151 seems to make things worse, I would suggesting reverting it from master until a working solution can be found.
is it required to scale on cuda? or is the multimedia api capable of doing custom framesize scaling?
hi, does somebody know, how to scale on hardware?

(And then it just sits, there, a non-patched ffmpeg works fine.)
