Current version is
7.5.7458 on OSX 10.9.5
I am having a similar issues to your fix in 7.2 video player doesn't work but it seems to be around the ffmpeg application.
I have my code as follows
#Use VideoJS for video playback (as opposed to FlashPlayer, which we are deprecating)
#If using FFMpeg to generate video thumbs and previews, uncomment and set next line.
# Create a preview video for ffmpeg compatible files? A FLV (Flash Video) file will automatically be produced for supported file types (most video types - AVI, MOV, MPEG etc.)
$ffmpeg_preview_seconds=120; # how many seconds to preview
$ffmpeg_preview_options="-f flv -ar 22050 -b 2048k -ab 32k -ac 1";
# ffmpeg_global_options: options to be applied to every ffmpeg command.
#$ffmpeg_global_options = "-loglevel panic"; # can be used for recent versions of ffmpeg when verbose output prevents run_command completing
#$ffmpeg_global_options = "-v panic"; # use for older versions of ffmpeg as above
$ffmpeg_global_options = "";
#$ffmpeg_snapshot_fraction=0.1; # Set this to specify a point in the video at which snapshot image is taken. Expressed as a proportion of the video duration so must be set between 0 and 1. Only valid if duration is greater than 10 seconds.
#$ffmpeg_snapshot_seconds=10; # Set this to specify the number of seconds into the video at which snapshot should be taken, overrides the $ffmpeg_snapshot_fraction setting
# $ffmpeg_command_prefix - Ability to add prefix to command when calling ffmpeg
# Example for use on Linux using nice to avoid slowing down the server
# $ffmpeg_command_prefix = "nice - n 10";
# If uploaded file is in the preview format already, should we transcode it anyway?
# Note this is now ON by default as of switching to MP4 previews, because it's likely that uploaded MP4 files will need a lower bitrate preview and
# were not intended to be the actual preview themselves.
# Option to always try and play the original file instead of preview - useful if recent change to $ffmpeg_preview_force doesn't suit e.g. if all users are
# on internal network and want to see HQ video
# Encode preview asynchronous?
# Find out and obey the Pixel Aspect Ratio
# Use New qscale to maintain quality (else uses -sameq)
$ffmpeg_use_qscale = true;
However in installation checks I get "FAIL:
'/usr/local/bin/avconv' not found"
I've tried custom installs of ffmpeg from ffmpegx, macports, brew, just a compiled folder in applications adjusting the path every time but its always trying to locate avconv.
Side effect of all this is I either get a 100x100 px box of the video playing in the top left corner or nothing plays. if I turn on $video_preview_original=false; (making this True) the system plays the file but only if its an mp4.
