Cant achieve the higher 720p quality ..

[greathappyforest]

I installed ffmpeg, and set up 'post_processor' => 'ffmpeg', but it looks like not working on youtube-dl gui.

Just wondering if there is any extra conf I didn't setup to enable ffmpeg?

[Kallys]

Hi! No there is no extra conf, MediaDownloader only checks if post_processor is actually installed, and youtube-dl should auto-detect it. Does MediaDownloader prevent you to start your download or MediaDownloader actually downloads but unwanted quality?

[greathappyforest]

Actually, I installed the MediaDownloader with the docker, and 'ffmpeg', youtube-dl and MediadDownloader are in the same container. However, when I trying to download the higher quality than 720p. The best option combine video and audio are always returned 720p videos, but I can see and download higher quality video or audio separately in the direct download.

I'm not familiar with docker, but what I could suggest to you is to test directly youtube-dl from a terminal. Output will help to determine if problem is from youtube-dl or MediaDownloader. youtube-dl -f bestvideo+bestaudio url_to_video

I think I got a k4 video download with youtube-dl inside docker. Can you check the parameter " --prefer-ffmpeg" correctly passing from frontend?

[Kallys]

I sent you a PR for you to test. I'm about to publish MediaDownloader v1.0 (which is a total rework), so I won't publish a clean fix for this bug, but I hope it will help you to wait until new version get released!

[greathappyforest]

Not work actually. I'm just wondering does ffmpeg works if running without docker? Can the new version running in the docker?

[Kallys]

Actually, it does work with avconv which is the default post processor used by youtube-dl (auto-detected). I never test with ffmpeg, but I know some linux distributions install ffmpeg instead of avconv (when you're installing avconv) and only do a symlink from avconv to ffmpeg. In current official version (v0), there is no real support of post processors. In new version (v1, now in dev branch), support is planned but not integrated.

Can you try installing avconv in your docker ?

Just added avconv and tried. Post-processors was also not working with avconv in the docker.

[Kallys]

Could be a docker integration issue (as I already said, I'm not a docker user). If you feel adventurous enough, you could try to install new version (v1b). This version would next allows you to add extra arguments to youtube-dl (such as post-processor path and preferences).

[Kallys]

Currently, post processing does not work in v1b (cf #13 ) Thanks for your patience, I'm working on it.
