Hi I am Rupesh from India and I have a PC with Linux installed and I have large size YouTube and WhatsApp MP4 files with codec x264. I want to convert these files into MP4 files with codec x265.
I have tested to convert these files using ffmpeg command x265 pass 1 and Linux shell script and I have successfully completed without any errors but I want to use ffmpeg tool x265 pass 2 to do the same job but I can't.
I got the following code from ffmpeg website and first I have tried to convert a single file and after that I have tried to use the similar code in Linux shell script.
Upon running the above command I am able to see .log and .cue files in the current directory.
For all cases I got only the following two errors.
The code I have executed without pass 2 is the following.
Can you suggest why I can't do the same job in pass 2 of ffmpeg command which has been successfull in pass 1 of ffmpeg command x265.
