mp4 video available using the format attribute -f string youtube-dl -f 'best' You can list the formats and see which is best for you youtube-dl -F Maybe have youtube-dl call the powershell script after each iteration. Like I could have youtube-dl download the audio, video, metadata and thumbnail to file, and then write a powershell script that does all I need to do. If not.then I think I might just go the route of writing this all myself in powershell.

if not mp4, convert video file to mp4 - extra step that I want to happen.

So.does anyone know, if there is a way to tell youtube-dl that when it downloads the video file, to immediately convert it to a given type (MP4) before doing anything else? However.if the video only webm file were first converted to MP4, then none of this would be a problem. My youtube-dl command (as recommended by the marked answer). This, all I simply needed to do was add '-merge-output-format mp4' to My solution was toĮxclude WEBM audio formats by using 'bestaudio'. (can be passed in via a youtube-dl parameter). In order to force this conversion you must add '-strict 2' to ffmpeg YouTube uses OpusĮncoding for WEBM audio, which when youtube-dl tried merging the twoįiles, it would end up having to use an MKV container rather than MP4īecause ffmpeg doesn't safely allow WEBM/Opus within an MP4 container. Was WEBM audio that was causing the problem. Was actually happening was that WEBM video was working fine, but it UPDATE: I later remembered the above statement is not accurate. Since this step is performed prior to the thumbnail embedding via AtomicParsley.An error is thrown, because MKV are not supported for thumbnail embedding. In cases where the 'bestvideo' is a webm detects that WEBM + M4A are incompatible and will be merged into an MKV file rather than MP4 (like it normally would). My current command: youtube-dl -f 'bestvideo+bestaudio/best' -embed-thumbnail -add-metadata

Output final file as MP4 - cannot be MKV.

Download the best video + best audio (default to 'best' if combo not.

For some of the more advanced options, there isn't much documentation, and I'm still learning Python.so going through the source code has been an endeavor.

I've found what I thought was exactly what I wanted.but I've run into a snag, and I'm curious to see if any of the more advanced options of youtube-dl could help solve my problem. I've poured through the youtube-dl documentation.
