Dear Support,

I am using Pulse SMS in Firefox 94.01 in Windows 10, https://pulsesms.app. I receive MP4 videos via this SMS web application and Firefox will not open them, they are coming from an Apple IPHONE. I receive the following error and the video will not play.

No Video with supported format and MIME type found

I open the same Pulse SMS app in Google Chrome, MS Edge, Vivaldi and each of those applications plays back the video fine and I hear the sound. I have disabled all extensions in Firefox, and also allowed all all the Site permissions for the web app site, I have turned off enhance tracking, note of the firefox settings seem to help The MP4 will not play. Can anyone point me to a setting that might allow me to playback these videos? I have looked thru the history of Firefox and it seems to be an issue that rears it's head quite often over the years. If anyone has a solution could you please let me know. thank you for your help!

Hello,

Thanks for the Links, I tried all of items in these links and none of them cleared the issue. I also noted this same same issue on a MACBOOK Air using Firefox with the same app. Hoping the Dev team can take a look at it at some point, it is very strange, Installing the Media Pack also did not help.

Any other ideas?

It is possible that the files are send as application/vnd.apple.mpegurl what might not be supported by Firefox.

The Web Console usually shows more information on what media formats the website offers, so you can check that.

cor-el Below is the error I found in the WEB_Console (thank you for the tip)

Cannot play media. No decoders for requested formats: video/3gpp, video/3gpp 818475741370879

The file link shows the file has a .3gp extension, I noted on the WEB that Firefox has fixed this in the past and I am hoping they could fix it in 94.01 or a future version as they have done it before.

Is there a way to submit a request to consider this as a Bug ? Or is there a place to request a fix? If I copy the Video Link to a new tab and it requests what I want to open it with and it plays back fine with opens in Windows TV app, Windoze Media Play, Ifranview, VLC Player and all other Browsers.

It appears to be an MP4 file format recoded to .3gp, would be nice if Firefox could play it back natively like other browsers. I have been a LONG LONG time Firefox user since it came out and really don't want to go to another browser. Thanks for your help!!

Booo Hisssss.... I think this is lame, Chrome, Edge, Opera, Vivaldi all do....

Am using Pulse SMS for WEB and it's an awsome SMS app as it has a simple to use and access WEB app, appears Videos from older Mac Iphones utilize this format.

How can one request consideration to add it back in? video/3gpp;base64

TIA
