Hi,
Can I know the given input file format?
If it is valid file format to convert as flv, please check the
following cases
1. you have to give permission to the ffmpeg utility to run on aspnet
user account
2. Read/Write permissions should be given to the input and output
directories as well as ffmpeg utility.
3. Check disk space whether it is enough.
4. and check Input file format too, whether it is convertible as flv.
(you can check this compatibility in ffmpeg site).
If still you can't fix this bug, debug the code let me know the actual
exception was thrown
Thanks,
Syed.
