Hello,
as the title suggests - mp4 videos don't seem to play for me since FF
57. See this test site for an example:
https://www.quirksmode.org/html5/tests/video.html - the other two
videos play just fine but not the first one. Used to work in FF 56 and
before without any issues.
I get this message in the dev console: 'Specified “type” attribute of
“video/mp4” is not supported. Load of media resource
../videos/big_buck_bunny.mp4 failed' or on some other sites messages
like this: 'The video on this page can’t be played. Your system may
not have the required video codecs for: video/mp4;codecs="avc1.4d400d
mp4a.40.2" ... ...'.
What is your video hardware? I have intel integrated graphics, and
LFS/BLFS development, and all 3 videos work
(thanks for the link, that makes a good test). Sorry, I know that "it
works for me" is not very useful, but at least we can compare what we
have and what not.
I tried upgrading to ffmpeg 3.4 as per the dev version of The BLFS
Book, also a couple of the decoding libraries I could think of like
libx264 and libx265 but so far no luck.
What about libva (recompile ffmpeg after upgrading libva)?
My base system is LFS/BLFS 7.10 (with a touch of BLFS 7.9 to get the
old KDE4 running but that's probably beyond the point).
As I'm slowly running out of (my arguably a rather limited range of)
ideas, would anyone have an idea what the problem might be?
That's all I can think of now.
Pierre
