Description of your issue, suggested solution and other information

When renaming a file at status=finished using a progress hook youtube-dl tries to post process the file using the old filename. Would it be possible to delay status=finished until post processing is also finished? Or to provide another status for the progress hook (status=postprocessed)?

I know this is old, but since google brought me here as well, I'll answer for the future.

Unfortunately, one cannot rename in this fashion as ffmpeg is looking for d['filename'] to do it's conversions.
The way I see it, there are 3 options to fix this issue.
1.) (I believe this only works for YouTube)Simulate the playlist with the same ydl_opts as if downloading, grab the desired video title and video id, pass the title through rename_files() then
ydl.download(https://www.youtube.com/watch?v=<your_video_id> without the "<>".
2.)rename all of the files after the download call you can use something like:
with youtube_dl.YoutubeDL(ydl_opts) as ydl: playlist_dict = ydl.extract_info(podcast['url'], download=False) for video in playlist_dict['entries']: title = video.get('title')
3.) skip pre defined post and import ffmpeg on your own and run that after the rename in the hook function.
