audio plays but video does not jw player

We have designed a tool using PHP and embedded JW player in it. All the videos which we play are in MP4 format. However some videos play and the others don’t. All we can hear is the audio but the video never loads. On investigating we found if the video data rate is equal to or below 1200 kbps then the video plays but if above 1200 kbps then this problem occurs. We converted the videos above 1200 kbps using format factory converter (frames per second = original frame rate; data rate = 1024 kbps; encoding = AVC H.264) and the video now plays. However due to conversion,there is a slight shift (100 to 200 milliseconds) in the frames of the converted video as compared to the original. We would actually want to eliminate the conversion process and would want to play the videos as it is. How do we do it? Else please suggest a converter that wouldn’t shift the frames.Please guide.

Thanks,

Hello Jaydeep,

I don’t know what could be causing this problem. Could you please use this script and see what it returns? You would simply put it in your WordPress directory and open it in a browser.

Hi Eudan,

Thanks for your prompt reply. I will get this script checked with my tool developer. However could you also suggest me a converter (free or paid) that wouldn’t shift frames post conversion.

I can’t really recommend anything, I don’t work with videos currently I’m afraid. But remember… Google is your best friend.
