Hi,
since build https://www.avidemux.org/nightly/win64/avidemux_r200415_win64Qt5_96.zip GUI seems to be non responding when using "Video size (Two Pass)" mode.
It appears during first pass only, second pass is OK.
Encoding in the background works fine, but any action on GUI (f.e. click on pause/stop button) is very slow - have to wait long time.
Win10 64bit, tested with multiple codecs (x265, h264) - always the same...
Should be [gui_savenew] Print first pass progress to the log only when it advances (https://github.com/mean00/avidemux2/commit/7f0f7f53e56cd0e925a9fc3a8626fdfe5f556283), evaluating options...
Should be fixed now (https://github.com/mean00/avidemux2/commit/e0d9f08dcb12fe7a0259611461e3e9b9a03f1eb2), thank you very much for your report. The regression was not evident with short samples I used for testing :-[
My pleasure... Thank you.
