  • AFTER PHP-FFMpeg not converting (error with ffmpeg)

    15 août 2016, par Magurean Dan Sergiu

    I have installed ffmpeg server side with all the dependencies, updated it. And then installed PHP-FFMpeg with Composer. Tested that ffmpeg is instaled with a ssh conexion.

Unknown encoder 'libx264'

    My question is what to do next ? I have wasted 3 days to make this work and this is the furthest I have come. How can I test if libx264 is installed corectly ? And if it is not installed corectly how cand I reinstal or make it work ?

    After a few modifications

    I have used an already installed ffmpeg, and removed a few commands (that were by default the same) and this time I used only the command line.

  • ffmpeg command for faster encoding at a decent bitrate with smaller file size

    14 septembre 2016, par Blair Holmes

    I’m currently using an implementation of ffmpeg on my android app. I’m allowing users to take short videos within my app and then when they upload them to the server, I’m crunching them down with ffmpeg to decrease file size so they’re not passing huge amounts of data over the wire.

    the problem is, it’s taking forever to encode the videos on the android device. These videos usually aren’t longer than 45 seconds and can take 20 minutes to encode. I’ve done some playing around with different switches / parameters on the ffmpeg command line and I now have it at a more comfortable time, but the file sizes are significantly bigger. I’m just not sure what codec I should use (fastest encoding but with decent quality output), how ffmpeg handles changing size (aspect ratio) in terms of speed of encoding etc.

    Here are the two commands I’ve been using. This first one outputs the file size / quality that I want, but it just takes way too long to encode, not to mention it makes my device get really hot while it’s encoding for so long :

    ffmpeg -i input.mp4 -b:v 1024k -c:a copy -vf scale=960:540 output.mp4

    I’ve tweaked the bitrate some on that as well as changed the scale to a smaller size, but I don’t want to have to make the videos really small (in terms of scale) to accomplish a faster encoding. this second command goes a lot faster but makes the file size significantly bigger :

    ffmpeg -i input.mp4 -vcodec libx264 -preset fast -c:a copy -s 960x540 output.mp4

    I’d like to find a happy medium (smaller file size but faster encoding) keeping the video scale size close to the original. ffmpeg just has so many different parameters / switches that it’s difficult to wrap my head around what I should be doing.

    EDIT : adding ffmpeg output.

    ffmpeg -i input.mp4 -vcodec libx264 -crf 30 -preset veryfast -c:a copy -s 960x540 output.mp4

  • 360 VR video to static ?

    7 octobre 2016, par SuperPrower

    So, I have simple 360 (or 180, I’m not really sure since I can’t play it) degrees side-by-side VR video, but my phone is so old, so it’s can play that kind of video, not matter what player I use (I was able to see few frames from such a video, but they were static or applications was crashing).

    Is there any way to convert such video into static one ? I understand that I will lost ability to rotate my head, but I don’t really care since my phone don’t have a gyroscope.

    I want to create simple side-by-side video which I could play with any player - I understand that I can lost quality and effect, but as I said, I don’t really care, since this is just something fun which I want to try.
