WFM with FF44 on Win 7. Any error in the console? Could you test with a fresh profile, please. https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles
I am having the same issue with certain mp4 videos. I have attached a sample video to this bug report. I tried opening the video using a clean profile, and I emailed it to someone and they could not play it either. I also tried to disable all of my plugins, but that did not help either. The exact message I am seeing is: "Video can't be played because the file is corrupt." As far as I can tell this only affects Firefox on Windows 7 (44.0.2) The video plays as expected on Firefox 44.0.2 on Centos 6.7. It also plays in VLC, Windows media player, and Chrome. The Video was transcoded using gstreamer 0.10.36 (And no, I cannot upgrade to gstremer 1.0 :-( ffprobe reports the following about the video: Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '.\out.mp4': Metadata: major_brand : mp42 minor_version : 0 compatible_brands: mp42mp41isomiso2 creation_time : 2016-03-04 18:46:04 encoder : VirtualDubMod 18.104.22.168 (build 2540/release) Duration: 00:00:18.24, start: 0.000000, bitrate: 2103 kb/s Stream #0:0(eng): Audio: aac (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 127 kb/s (default) Metadata: creation_time : 2016-03-04 18:46:04 handler_name : SoundHandler Stream #0:1(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 528x224 [SAR 1:1 DAR 33:14], 1970 kb/s, 24.99 fps, 25 tbr, 1250 tbn, 49.99 tbc (default) Metadata: creation_time : 2016-03-04 18:46:04 handler_name : VideoHandler
Also, I believe the problem has to do with the AAC audio stream. When I drop the audio during transcoding, the video plays although without sound of course.

In reply to Loic from comment #5) > https://hg.mozilla.org/mozilla-central/ > pushloghtml?fromchange=9696d1c4b3ba&tochange=986e840a2979 I am not sure I understand your reply. Is there anything else I can help with regarding this issue?
It's a regression range for devs. As the link of video is broken in the original message, I suggest to create a new bug for your issue.
Bug closed as incomplete because the link to the MP4 video posted in the original message is broken. In addition, the reporter didn't answer to the NI flag. Reporter, feel free to reopen this bug if you can provide the video again and reproduce the issue with FF44 or next versions.
