ffmpeg to convert video to play in mobile phones.

skillednerd · 04-05-2011, 06:57 PM

Is there a way I can convert video with ffmpeg to be in mp4 format and play on either iphone or android?

I can't seem to get anything that I convert to play on a phone.

I can get other mp4 files I found to play on the phone but any file I convert into that format won't actually play.

Any help would be very appreciated and I thank you in advance!

Hi skillednerd, Welcome to LQ. I'd suggest trying 3gp format.

Code:

ffmpeg -i inputfile.mpg -s qcif -vcodec h263 -acodec aac -ac 1 -ar 8000 -r 25 -ab 32 -y outputfile.3gp

Good luck. ;-)

Ok thanks. I tried that and when loading the 3gp file on phone it says sorry this video is not valid for streaming to this device.

What type of phone, please explain "streaming". You should be able to convert a video, place it on your sd card (Android) and access it from the internal player or Astro or something similar.

Good luck. ;-)

I have a droid phone. MotoCliq. I need it to play on phone loading from website. I want others to view video.
So loading on sd card isn't an option. I can get other 3gp files to play. So it has to be the way I am converting
it.

Have you tried just converting the video to flash? It sounds like a browser issue not a video issue.

Good luck. ;-)

It has to be in mp4 format to work with the rest of the script I wrote.

I actually got it all working with two passes. If its less than 10 seconds
it will play on droid phone. If its longer than that it just sits saying loading
without ever changing I even let it go an hour with a 20 second video.

Could it be the script and not the content?

Good luck. ;-)

No I tried just using command prompt to convert and that does the same thing.

If the file is okay and the script is okay, it's likely something on the server side, the stream itself.

Good luck. ;-)

I'm not using a stream. Its my server and I do have flash media server but this isn't for streaming. I just want to be able to upload videos and they show on phones. I am just sending the phone a link to the file and it loads it. But for some reason its not working. I need some testers with phones maybe its my phone then. I am not sure.

I still think flash would be your best bet. I've uploaded flash video to my server and it plays fine on my Android phone.

Good luck. ;-)

skillednerd · 04-07-2011, 09:57 PM

Yeah that would make it easier for sure. I did figure it out though what I had all along was correct. I download a few different videos in different formats and converted them and they all work on the phone. So I guess the other file I was testing with just doesn't work for some reason.

Thanks for you help Peacedog!
