H264 480p videos won't play on my iPhone 3G (5 posts)

    Hi Kyle,

    Thanks for a great plugin! I only just found it a few weeks ago, I had no idea something as great as this existed for WordPress.
    I am using the latest version of FFMPEG, 5th December 2013. The H264 and AAC all convert fine, and the OGG and WEBM if I need them.
    I did get some stream errors earlier on some files while trying to convert, but seems ok for now.
    My only question is, I make an HD version H264 and also a 480p version in H264 for mobile devices. It all works fine on all browsers and my HTC One droid, but when I checked with my old iPhone 3G, the videos don't play on it. Possible they also don't play on other iPhones.
    I don't have a newer iPhone, so I can't check.
    Since we have to keep the Apple lovers happy as they make up a load of viewers do you know the solution for this?. I am using the Video.js player, it just spins on the iPhone, only plays two videos I uploaded that were small in size to begin with, so I am thinking, maybe the javacode isn't switching to the 480p version of the file, due to something conflicting. I also have qt-faststart enabled to fix the H264 streaming headers while encoding videos.

    Here is the FFMPEG sample H.264 encode command:

    /var/www/ffmpeg -y -i "http://www.jasondolan.co.uk/wp-content/plugins/video-embed-thumbnail-generator/images/sample-video-h264.mp4" -acodec libvo_aacenc -b:a 160k -s 640x360 -vcodec libx264 -profile:v baseline -pix_fmt yuv420p -level:v 30 -crf 23 -threads 0 "/var/www/wp-content/uploads/2013/12/sample-video-h264-480p.mp4"

    Here is the FFMPEG test output::

    Hi Jason, I'm glad you're enjoying the plugin, but I'm not willing to put in the work to support a 5-year-old cell phone. In my experience it works fine on iPhones 4 and up.

    Hi Kyle,

    It's actually an iPhone 3GS. So not as old as 5 years yet. 2010 model.
    I can play any video, it's just if the original is HD and I convert original to H264 it won't play on it, even with 480p.

    I am able to play with Wowza on the same phone, so probably some code.
    but when I looked into the specs, baseline, 3.0 but the audio must be 64K.
    Could be that.

    Anyway, I've been experimenting a bit, If I upload a 5.1 surround sound video file, it always fails to encode.
    I would probably need to add more commands maybe?.

    Here is the log:

    I hope you keep updates now and then when you have time, it's a really good plugin. I can't find any other WordPress plugin that has these features.

    Thanks,
    Jason.

    I think you might be running into this problem with multiple H.264 sources:
    https://github.com/videojs/video.js/issues/662 Do you have the same problem if you switch my plugin's video player to the WordPress Default player?

    According to the FFMPEG AAC Encoding Guide libvo_aacenc only supports 2 channel audio. If you configure FFMPEG with libfdk_aac you might have better luck. I would worry about device compatibility with any 5.1 file though.
