View Full Version : [ubuntu] How to convert invalid MP4 for playback on the PS3
May 31st, 2011, 12:45 PM
I've just been searching in vain for a way of converting a MP4 I have that is h264 video and aac audio, so that it will play properly on the PS3.
It currently will play on the PS3 but at double frame-rate and without sound. Does anyone have any ideas. I'm not particularly wanting to re-encode the whole thing.
Even advice as to how to demux the audio and video streams from the MP4 would be useful.

Not much success with the demuxing. I've found little in the way of advice for how to handle MP4s, most online guides tend to focus on MKV to MP4 and use mkvextract to demux audio and video streams. (For examples see here (http://www.ode2.com/?p=11).)
I've had better success with transcoding (though it takes a bit longer). This page (http://www.prupert.co.uk/2009/10/10/how-to-use-ffmpeg-to-transcode-video-for-the-ps3/) has instructions for transcoding using ffmpeg, libfaac and libx264 into PS3 compatible MP4 that worked for me.
The second ffmpeg command on the page worked:
ffmpeg -y -i my_video_file -vcodec libx264 -level 41 -vpre normal -crf 24 -threads 0 -acodec libfaac -ab 128k -ac 2 -ar 48000 my_video_file_out.mp4
However I had to install the unrestricted video libraries from medibuntu.org (http://medibuntu.org/repository.php). Follow the 2 sets of instructions on the page for Adding the repository then upgrade:
sudo apt-get upgrade
Would still like to know if anyone can do this without transcoding. The exact video MP4 I'm trying to make compatible is the MP4 files produced using get-iplayer.

Sometimes those files from get_iplayer are available in different versions.
Have you tried the different ones with your PS3 ?
640x360 (382Kbps - LOW BITRATE !)
--mode=flashhigh (Not needed, because it's the default).
