I have used my Android cell phone to record online lectures while driving home. The problem is that the version of Android across all my devices is 32 bit, so the maximum file size is limited. Because of this I now have dozens of MP4 files which cannot be played because they were not properly closed out (no EOF given). I've tried: Arista Transcoder Avidemux & Avidemux 2.6 (GTK+, QT and Jobs) Flowblade Movie Editor Handbrake Kdenlive LiVES OpenShot Video Editor Pitivi Transmageddon Movie Transcriber VLC But with no useful result.
How does one restore playability to MP4 files which were improperly stopped while recording? My last idea is to try Testdisk to see if it can produce functional MP4 files from the existing non-functional files (I've avoided it so far because of the volume of time and space it requires to even attempt as much).
Thank you, David
