[FFmpeg-user] Help converting .mov and .mp4 to .mp4 and playing in JWPlayer5

Tue Jan 14 17:46:42 CET 2014

Hello,

Thank you for your help.

I am still having difficulty with .mp4 files, from your reply I understood that I should also be re-musing mp4 files into mp4. I have tried using the file as is, (with no ffmpeg command run on it) but in JWPlayer5 and JWPlayer6 I am getting audio, but no video. (Although the video plays fine in Quicktime on my local machine)

I have tried using the -pix_fmt yuv420p flag and without with the same results. The original video is 0:39 and the remuxed video is 0:01 in length. I removed all the size flags.

Please let me know if you have any additional insight.

I have tried to remux with the following command:
/usr/bin/ffmpeg -i '/var/www/vhosts/[SERVER_NAME]/public/htdocs/uploads/Eva_La_Rue.mp4' -codec copy -y   '/var/www/vhosts/[SERVER_NAME]/public/htdocs/uploads/Eva_La_Rue.mp4' 2> '/var/www/vhosts/[SERVER_NAME]/logs/ffmpeg/01-14-2014_11-14-42_mp4.log'

To get the following output:
