  • ffmpeg : using the returned data in php

    4 décembre 2013, par user1503606

    I have started using ffmpeg and I am very new to it, so please bear with me.

    I have installed ffmpeg on my server and it works great ; I can run certain commands and get output data when logged in via ssh

    For example I can run

    ffmpeg -i Sleep\ Away.mp3

    Which returns the following :

At least one output file must be specified

    The question I am asking is, how can I use the output data above ? I am developiong a music website ; say I want to loop through all the MP3 files and save the info about them into a database, so that the above would result in :

    Sleep Away.mp3    mp3    3:21    Jazz    2004     Bob Acri ...

    obviously in a table

    I have tried to use the php backtick operator with no success so far. I just thought I would put a question up here to get some advice from people that have done something similar.

    Thanks

    Update : I have tried the following

    &lt;?php $output = `ffmpeg -i Sleep\ Away.mp3`; echo "<pre>$output</pre>"; ?>
    
&lt;?php $output = shell_exec(&#39;ffmpeg -i Sleep\ Away.mp3&#39;); echo "<pre>$output</pre>"; ?>

    both don't appear to return anything.

  • Encode x264 video with ffmpeg for Android with starting offset

    4 août 2013, par scubed

    I'm trying to convert a video to play on an Android device.
    The video is from a big movie. I am chopping it back into pieces
    to correspond with the actual segments of the movie using -ss and -t.

    The input is mp4 with H.264 and AAC.
    The output is mkv using H.264 and Vorbis.

    Specifically, the input is :

    Stream #0:0(und): Video: h264 (Main) (avc1 / 0x31637661), yuv420p, 320x240, 2240 kb/s, 29.97 fps, 60 tbr, 90k tbn, 180k tbc
    
Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 48000 Hz, stereo, s16, 162 kb/s

    I'm using : ffmpeg version 1.0.7

    The command I'm trying is something like :

    ffmpeg -ss 00:03:52.000 -i in.mp4 -t 00:01:00.000 -c:v libx264 -preset medium -crf 20 -maxrate 400k -bufsize 1835k -c:a libvorbis -sn out.mkv

    However, while the resulting video works fine on my computer, when I click on
    my phone, it says : Can't play video
    and checking the Android log, it has :

    E/SoftAVC (24319): Decoder failed: -2
    
E/OMXCodec(24319): [OMX.google.h264.decoder] ERROR(0x80001001, -1007)

    It is still able to make a thumbnail for the movie, but not play it.

    Interestingly, some simple variations of that command do work :
    Remove -ss to start at the beginning of the video
    Use -an to disable audio

    These variations still failed :
    Copying the original audio with -c:a copy, or other audio codecs like vorbis, mp3
    Using mp4 instead of mkv
    Using baseline H.264 profile, including restricting level to 1.2.

    Running through mkvmerge first not only fails, but makes Android not able to even make a thumbnail.

    I don't know if it is related, but another small thing I noticed is that for
    starting transcoding later in the movie, the audio starts out slightly out-of-sync.
    After several seconds, it gets back in sync. The audio is in sync in the original.

    Robert Rowntree :

    -vcodec libx264 -b:v 200k -bt 50k -threads 0 -b_strategy 1 -acodec copy -f mp4 -strict -2

    Interesting. Your command almost works. The video actually plays on Android. The one problem is that the audio is out-of-sync and stays out-of-sync throughout the whole clip. But, that's much closer than I've been. I'll search around there and see if I can find the right combination.

    I tried combinations of it. It appears that using both mp4 and copying the audio is what allows it to work. Using libvorbis or going to mkv breaks it again. But, I would like to transcode the audio, and I suspect to keep it in sync, I might have to transcode it anyways. Note that even with transcoding, when I play it back on the computer, I still don't have sync between audio and video.
