Can you reproduce your problem with ffmpeg (the<br>
application)? Do you agree that it is significantly<br>
easier to reproduce issues with ffmpeg (the application)<br>
than with custom C code?<br>
<br></blockquote><div>You see, if I call ffmpeg through executable, then I can choose a preset and encode it, after it is done with encoding, ffmpeg.exe application exits. Now, if I choose another preset and pass it through ffmpeg, then it is basically a different process, in which case this (bug/observation) does not apply (hence not reproducible).<br>
<br></div><div>On a broader scale: suppose I have an application that can encode to HEVC using different presets. I can choose a preset and encode it, but after 1st time encoding, if I select another preset (like mentioned with original email), I cannot encode it. So in order to do that, I must first close my application, launch it again, select an input file, then choose another preset, then encode it again (which will work)<br>

Did you try with x265 (the executable)?<br>
I am not sure if using different presets for two-pass<br>
encoding is supported, I am quite sure it is not<br>
recommended.<br>
<br></blockquote><div>Have not tried yet, but I doubt it is relevant since x265.exe will be another application again.<br><br>Surprisingly: I can choose following presets and interchange them without libx265 giving me any error:<br>
