no sound in youtube video unless the audio .webm gets ffmpeg-ed into .ogg with "-c copy" first #7048

Closed ghost closed 8 years ago

ghost commented 8 years ago

youtube-dl --user-agent "Mozilla/5.0 (X11; Linux x86_64; rv:39.0) Gecko/20100101 Firefox/39.0" -k https://www.youtube.com/watch?v=DYGc-31mEec

That pulls a *.f136.mp4 video, a *.f251.webm audio , and they get converted into a .mkv but with vlc there's no sound (either on the .webm or the .mkv files, in fact the sound card goes to sleep, even though statistics say that audio gets decoded just fine). If I run opusinfo *.webm I get some errors which say that's not a valid ogg. Then if I convert the webm into ogg via ffmpeg(this shaves 453,728 bytes) then there's audio on the resulting .ogg; this ffmpeg command: ffmpeg -i "file: ASMR Ear (Cleaning) Groomers & Spa Roleplay (unisex)-DYGc-31mEec.f251.webm" -c copy "file:stuff.ogg" I tried renaming webm to ogg but there's still no audio, so that ffmpeg conversion is needed apparently. Maybe's my vlc acting out? (latest git, but config options may matter)

EDIT: forgot to mention youtube-dl version, since it's not latest git: $ youtube-dl --version 2015.09.28-gentoo_no_offensive_sites

Looks like for extracting audio only, the sound works fine(in vlc player) because it gets transformed from webm into opus by youtube-dl via this command: ffmpeg -y -i "file:Epic Action _ Path of Aroha - In The Shadow of a Colossus - EpicMusicVN-BNyuHH7kUJk.webm" -vn -acodec copy "file:Epic Action _ Path of Aroha - In The Shadow of a Colossus - EpicMusicVN-BNyuHH7kUJk.opus"

Command I used: youtube-dl --user-agent "Mozilla/5.0 (X11; Linux x86_64; rv:39.0) Gecko/20100101 Firefox/39.0" --extract-audio https://www.youtube.com/watch?v=BNyuHH7kUJk

And if I pass the -k param, it gets the video file too, but vlc-ing the webm file (or the resulting mkv) still no sound! (good thing it does an opus too, with the -k arg, although maybe it shouldn't pull the video? guess that's another issue though)

Works fine for me with vlc 2.2.0 and mplayer. So it's probably something wrong with either your ffmpeg or vlc.

ghost commented 8 years ago

Thanks for looking into this. I can confirm it works with mplayer. Sorry for the trouble.

EDIT: It's definitely vlc(not ffmpeg) because it does the same thing when compiled without ffmpeg, and this is vlc 2.2.0 (it decodesdemuxes just like the git version, but still no sound) screenshot_2015-10-03_21-38-12

ghost commented 8 years ago

Can you look in vlc Tools->Messages(Ctrl+M) in the Modules Tree tab and say whether the demux is "avformat" or "ogg" while the audio of the .webm is working for you? That's under libvlc->playlist->input->demux...

Looks like for .opus is demux "ogg" but for .webm is demux "avformat" and in the latter case Audio decoded/played remains 0 (for me). (in Tools->Media Information(Ctrl+i) Statistics tab) whether I'm using vlc 2.2.0 or the git version. With or without ffmpeg compiled in. I've no idea how to fix it currently. But clearly since with mplayer works, it must be something on my side.

dstftw commented 8 years ago

This is for 251 webm: vlc

ghost commented 8 years ago

Amazing! I didn't have --enable-mkv which is because gentoo has the matroska USE flag disabled by default, and now it works as it does for you, with demux "mkv" and audio works fine! It previously was demux "avformat" (with no audio being heard)

If any gentoo users stumble upon this no audio (no sound) issue on (some of) the .webm and .mkv files, just remember to USE=matroska when emerging vlc.

Thanks a lot for the help @dstftw ! Much appreciated!

EDIT: for consistency, I'm posting the emerge --info of the working setup:
