firefox can't play videos (on DragonFly)

[mneumann]

It shows "Your browser can't play this video".

[jrmarino]

that suggests it's a codecs thing. Can you check a video and ascertain if the codec is installed? if not, firefox should be pulling those in.

[mneumann]

@jrmarino ffmpeg is installed via ravenports. I can use ffplay to play videos with it.

Tried to install gstreamer, but firefox plays no videos either.

[jrmarino]

I was curious about right-clicking on the video to get info on the needed codecs.

This is what right-clicking and selecting "Copy Debug info" shows:

I don't see the video codec.

Clicking on "Stats for nerds" displays a row "Codecs", but leaves it empty :/

[mneumann]

I think, without a proper video decoder, you cannot display the codec properly :/

[mneumann]

Opening the developer console gives more info:

HTTP “Content-Type” of “video/mp4” is not supported. Load of media resource 
data:video/mp4;base64,AAAAHGZ0eXBpc29tAAACAGlzb21pc28ybXA0MQAAAAhmcmVlA.....

[jrmarino]

perhaps there's a missing map file (to map video/mp4 to ffmpeg)?

[jrmarino]

@jrmarino ffmpeg is installed via ravenports. I can use ffplay to play videos with it.

Tried to install gstreamer, but firefox plays no videos either.

I interpret this to mean both the primary and tools subpackages of "ffmpeg" are installed.
Just curious, is ffmpeg dev subpackage installed? if not, can you temporarily install it and try firefox again?

[mneumann]

yes, both primary and tools are installed. dev packages does not help either:

root@letsnote:/home/mneumann # rvn info|grep ffmpeg

ffmpeg6~dev~std~6.1.2_2                      Play, record, convert, and stream audio and video (dev)```

[mneumann]

Dunno where I could configure the map file. It should not open ffmpeg as an external application. The media player should be built into Firefox. Maybe it's not properly configured at compile time...?

[jrmarino]

ffmpeg~dev~std~7.1 wasn't installed though ...

[mneumann]

you are referring to build time?

[jrmarino]

no, when you showed output of "rvn info|grep ffmpeg", the ffmpeg dev package wasn't installed. only ffmpeg6's was installed.

[mneumann]

It is installed and still no videos:
