I still see people continue to have problems with Dolphin video uploads - errors on a regular basis.
There are a few things you can check.
Many Fast Cgi (CGI/FastCGI) setups upload folders/directories need to be 777, but ffmpeg.exe needs to be set to 755. If not it will error out.
Suphp (may say CGI or CGI/FastCGI) setups folders need only 755 to upload, and ffmpeg.exe should also be set to 755. If you try to set 777 it probably won't work at all.
DSO (Apache Handler - Mod PHP) setups upload folders/directories need to be 777, and ffmpeg.exe should also be 777.
(Variations of these are possible, but the above mentioned are fairly common)
After changing permissions, recheck in Dolphin Administration Host Tools to verify the folders/directories say writeable, and ffmpeg.exe says executable.
Increase max values if necessary by using:
(CGI, FastCGI, Suphp) use a php.ini file to increase values.
(Apache Handler, DSO, Mod PHP) add php_value codes to your main root .htaccess file.
After doing so, check in Dolphin 7 Administration Host Tools again.
Be sure you have also setup and entered the correct cron command path and configuration in your hosts control panel.
You might also disable the H264 codec in:
Video Player Settings
Uncheck the Use H264 Codec
With some setups and configurations H264 does not work or does not work right. If you are having video upload problems you might disable it.
You can also navigate with your favorite ftp client to:
After you have completely uploaded a video, given it a title, description, category, and saved it uploaded videos will appear in the above location.
Once processing begins by cron, it can take up to 5 mins (or more if you have made any custom changes to your cron). Then, on top of that depending on how large the video is it can take a minute or two, or it may take several minutes to totally convert your uploaded video.
Be patient and make sure you allow enough time before you are sure it didn't work. For testing purposes you would be better off uploading a smaller sized video say 1-5 mb's, and uploading one that is in a common or popular format to begin with (maybe a .wmv, .mpg, .mpeg, or other common type).
Make sure your max values are sufficient sizes to upload your video.
You can check these in Administration Panel:
Find Host Params, and also Phpinfo:
Make sure memory_limit, max_execution_time, post_max_size, and upload_max_filesize are large enough to accommodate your video.
For some CGI or CGI/FastCGI setups you may need to increase these values with php.ini in more than just your home or root directory. You may need to place a php.ini file in several folders/directories (where files are uploaded for example, but other locations as well).
DSO/Apache Handler/Mod Php setups usually adding php_value to the main .htaccess file (yoursite.com/.htaccess) is sufficient to cover all folder/directories.Note:
It is also possible that you won't be able to increase these values if your host has disable that feature on the server.
To determine which your host uses navigate in Administration Panel to:
Find the Phpinfo link and near the top look for:
Your host should be able to run executable files (necessary for ffmpeg.exe). If not ffmpeg.exe will not even be allowed to start up/execute.Additional:
