Generate lots of huge size tmp MediaDataBox files after cutting and appending MP4 clips #315

Hi,

I found lots of huge size tmp files after cutting and appending MP4 clips: Any solution I can apply?

isoparser and muxer version is 1.9.34.

[root@localhost temp]# du -h * 11M MediaDataBox3353323537304459708org.mp4parser.boxes.iso14496.part12.MediaDataBox@648dabab 38M MediaDataBox4936790949145394189org.mp4parser.boxes.iso14496.part12.MediaDataBox@2d9239fc 5.8M MediaDataBox533456596869457275org.mp4parser.boxes.iso14496.part12.MediaDataBox@334394a1 3.1G MediaDataBox8634033729187507380org.mp4parser.boxes.iso14496.part12.MediaDataBox@2f5cd9a4

Thanks Evan

Hey sorry this is another question and not an answer.. I added the muxer dependency in pom.xml, but it still says can't resolve 'muxer', and I get the following errors:

I was hoping you could help me?

Met this problem too. I've run out of /tmp space when just wanted to list and display video and audio streams metadata. I expected that /tmp will be cleared when i call .close() on an IsoFile instance, but it does not. Is it really necessary to unpack the full media into /tmp when i'm just reading content?

Hello

Thanks a lot for this fix (https://github.com/sannies/mp4parser/commit/7bc0bbb638fba8bfa078172b07fb6b4a60d3894c), but I think it will not solve the issue on server-side applications. Since the process never exists, the files will not be deleted, and that leads to running out of disk space (which can cause the application to crash).

I think mp4parser should provide a way to free up resources such as disk space.

best regards

I have same problem. Any one know where I can access MediaDataBox to change source files and delete tmp file?

scooter1556 commented 4 years ago

I am using this library as part of a server-side media transcoding solution and have realised today that my /tmp directory is consuming 150GB and contains hundreds of MediaDataBox* files. The application isn't designed to be restarted frequently and can run for weeks/months/years which makes this a big issue. Is there an alternative way to ensure temp files get cleaned up on closing of an IsoFile? The only other thing I can think to do is add a routine to frequently check for temp files and delete them but this isn't ideal and seems hacky.
