Php — convert avi to mp4, webm and flv using ffmpeg command

My problem is I am trying to convert and upload videos into three formats at upload button. I am stuck at the very first step when i am trying to convert avi to mp4, webm and flv. I have tried various commands to convert in to mp4 and webm but nothing worked. its converting to flv smoothly. i searched a lot on internet but none of the commands worked. i have set execution_time to 0 and set_time_limit(0) as well for unlimited execution time. here are the commands i tried to convert in to mp4 and webm

**For mp4:** exec("ffmpeg -i input.avi -c:v libx264 -crf 19 output.mp4"); exec("ffmpeg -i input.avi -c:v libx264 -pix_fmt yuv420p output.mp4"); exec("ffmpeg -i input.avi -c:v libx264 -c:a libfaac \ -movflags +faststart output.mp4"); **For webm** passthru("ffmpeg -i input.avi output.webm"); passthru("ffmpeg -i input.avi -b 1500k -vcodec libvpx -acodec libvorbis -ab 160000 -f webm -g 30 output.webm"); 

Note: For avi to mp4 files that are less than 1mb are converting successfully but more than 1mb files are showing its converting but its size is 0bytes.

Similarly, i am facing a problem in converting mp4 to flv. Some files are converting and some are not. Some of the large files are converting but some small files are not converting. It was strange. there was no problem of permission or php configuration settings all was fine. I tried renaming a file which was not converting and it got uploaded. I am confused why this happened.

Any help for both the issues is highly appreciated.

Ok first you need to debug your exec with files not encoded. echo your exec and put it into your shell with the same user than run Apache.

Ffmpeg — creating thumbnail from webm format and converting webm movie to flv movie

I have got a problem in which i want to make a thumbnail from webm movie using ffmpeg.

I have this error when trying to make that thumbnail:

«Unknown format is not supported as input pixel format»

Furthermore i want to convert webm movie to flv movie.

Assuming that your copy of ffmpeg has been compiled with support for webm, making a thumbnail should be as simple as:

ffmpeg -i input.webm -vframes 1 output.png 

Perhaps with some -s WxH thrown in if you want the thumbnail to be smaller than the video.

Converting to flv is similarly simple:

ffmpeg -i input.webm output.flv 

Just add «video/webm;» to the end of /usr/share/thumbnailers/ffmpegthumbnailer.thumbnailer

Converting video files to HTML video compatible formats

This simple script uploads a video file and converts it with ffmpeg to mp4 and webm format.
There’s no error handling. This is just a rough initial test to solve a headache of mine.

Note that converting to webm is painfully slow! Just give it some time and make a nice progress bar.

You need ffmpeg and also a couple of addons to be able to convert to webm.

brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aacc

If you already have ffmpeg installed and need the addons, just reinstall ffmpeg with the addons.

brew reinstall ffmpeg --with-libvpx --with-libvorbis --with-fdk-aacc

No installation besides ffmpeg needed. Just make sure you have the right file permission on the original and converted folders.

sudo chmod -R 775 original converted
