here is the following environment:
- 1and1 shared hosting (they do not have ffmpeg installed, all good)
- i built a static ffmpeg binary that does not require dynamic loading of shared libaries (i built this on an Ubuntu system)
- ffmpeg binary is fully accessible and is able to get access
- executing the same command terminal or executing a php/perl script via terminal works fine…however, both scripts through a browser/web request fails with the following:
Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

You can see i have the full path of my ffmpeg binary and that it is executing. Here is what it looks like successfully via terminal:

The user running the script at terminal AND the apache user are the same user…i have verified this.
Something about the environment apache is running through is killing me…i dont have access to apache error logs unfortunately.
As a side note…i am trying to utilize the Video Embed & Thumbnail Generator for wordpress.
Any help appreciated, thanks!
