#264070 — Firefox 115.5.0esr(64-bit) can't show mp4

[Multipart message — attachments visible in raw view] — view raw

When I try to view a mp4 video in Firefox 115.5.0esr(64-bit) on Debian
GNU/Linux 10 (buster), it puts up a sad-face window saying "No video
with supported format and MIME type found." It doesn't offer to
download the file, or play it with an external application.

ffmpeg is installed and up-to-date.

Can it be made to work?

Hi,

The problem here seems to stem from the video being 'Simple Profile' for MP4.

https://en.wikipedia.org/wiki/MPEG-4_Part_2

Some further testing maybe in order and an issue submitting if this is widespread.

Phil

Please do not send separate copies of replies to everyone who has posted 
in a thread.

Use Reply To List, if your email application provides that option, or, 
if you use Reply To All and that includes multiple email addresses in 
the To field, delete all email addresses from the To field, apart from 
the list email address.

Why annoy people through multiple reply copies, and, waste bandwidth of 
your victims?

Hi,

The reply going to 'all' was in error, apologies.

Your overreaction and use of the word 'victims' regarding this error is offensive. Please do not
speak via any medium to me like this again.

Hi,

It seems the 'simple profile' falls under H.263, which no longer has major browser support.

Hi,

I had a play with one of my ffmpeg video conversion scripts.

For the most compatible MP4 to deliver to your website visitors, I would use the 'main' profile with
ffmpeg. As an extra, I looked at restricting the 'bitrate' and also using the 'veryslow' preset to
try for better compression.

The bash script attached I think gives wide compatibility and good end file size - around 10.6MB. I
hope this is of help to you in its current form of if you wished to make changes to it for your
needs.

Regards

Phil

1. I believe that it is wrong to post the whole of a reply as you have, 
immediate before the signature of the person to whose message, you are 
replying, as it makes it too easy for people to misconstrue, for 
example, in the above case, that what you posted, was posted by me.

2. "I would expect Firefox to offer to download the file or choose a 
viewer" - I believe that you can configure Firefox to apply a third 
party application, such as a viewer of video files, for dealing with 
particular file types/extensions.

3. "I would expect Firefox to offer to download the file or choose a 
viewer" - why do you not simply download and install one or some of the 
video downloader add-ons that are available for Firefox?

4. If you do not know how to do either 2 or 3, I suggest that you 
subscribe to, and, post a query to, https://groups.io/g/firefox-support

I have not exactly the same problem but video related. 115.3.0 esr can 
play videos mostly OK but after an extended period of time (say a day or 
so) the video controls become sluggish and the CPU goes through the 
roof. I have to completely kill all processes including the video 
container processes before it can be restarted and run normally.
