MPEG Streamclip will no longer open/play mp4s etc.
Hello,
I recently had to reinstall OS X 10.11.3 and all other open source and licence purchased software onto my Mac HD.
The unique free MPEG Streamclip 1.9.2 will recognise title of mp4 file (shows in application viewing window) but says "File open error: unrecognised file type".
Clicking "open Anyway" button brings up window "File open error: can't find video or audio tracks" warning.
This free program is quite unique in that, despite being free, it alone enables users to change video frame size, alter brightness, contrast and saturation as necessary as well as converting to a range of alternate formats.
Has any other users of MPEG Streamclip experienced this inability to open mp4 and other video format files under El Capitan 10.11.3 ( MPEG Streamclip worked fine under 10.11.2 and earlier OS X versions? I will be grateful for any advice you can offer.
Sincerely, paulranger1.
