Failed to read duration of file, Samsung S6 MP4s

moviepy==0.2.2.11

I printed out each line of the file:

It looks like there is no "Duration :" in the header, so this (https://github.com/Zulko/moviepy/blob/master/moviepy/video/io/ffmpeg_reader.py#L264) fails with List index out of range

Even if I skip that if statement and explicitly set result['duration'] to something random (float(5.31)), it fails later down the line here: https://github.com/Zulko/moviepy/blob/master/moviepy/video/io/ffmpeg_reader.py#L273

Any idea why the headers might be corrupt?

Here's some information from VLC

This is another video that gives the same "error reading headers" (from a Samsung S3) when trying to use MoviePy, but it succeeds if I use ffmpeg from CLI

output.png is exactly what I expect... not sure why moviepy can't read the headers. :/

It looks like this was my fault.

I was reading in a file from s3 using requests and writing the contents to a tmp file and reading that into VideoFileClip. For some reason, it worked with some files, but wouldn't work with others without a .seek(0) on the new file.

Closing this for now.
