  • Handling correctly the ffmpeg & ffprobe with php

    29 septembre 2014, par cocco

    Handling correctly the ffmpeg & ffprobe with php

    maybe not relevant final goals :

    1. upload clip with ajax
    2. get ajax info from ffprobe using php as json executing ffprobe once only (no ffmpeg)
    3. handle all calculations with javascript
    4. maybe an extra php script tool that can create gifs, extract frames(thumbs), or a video grid preview
    5. when rdy ajax the conversion info to the final php conversion script executing ffmpeg once only (just the final ffmpeg string.).

    I’m trying to write my own ffmpeg local web video editor that converts all formats to mp4 automatically. As mp4 is the most compatible container now and the h264+aac/+ac3 is also one of the best compressions. I also want to be able to cut, crop, resize, remove streams, add streams and more. I’m stuck on some simple problems :

    1. HOW TO GET THE INFO ?

    I’m using ffprobe to get the file information as json with the following command :

    ffprobe -v quiet -print_format json -show_format -show_streams -show_packets '.$video

    this gives you a lot of information, but some relevant stuff is not always present. I need the duration (in milliseconds),the fps (as a float) and the total frames (as an integer).

    i know that these values can sometimes be found inside this array :

    format.duration //Total duration
    
streams[0].duration //Video duration
    
streams[1].duration //Audio duration
    

    
streams[0].avg_frame_rate //Average framerate
    
streams[0].r_frame_rate //Video framerate
    

    
streams[0].nb_frames //Total frames

    but most of the time nb_frames is missing, also avg_frame_rate differs from r_frame_rate, which is also not always available.

    I know that i could use multiple commands to increase the chance to get the correct values.. but srsly ???

    //fps
    
ffmpeg -i INPUT 2>&1 | sed -n "s/.*, \(.*\) fp.*/\1/p" 
    
//duration
    
ffmpeg -i INPUT 2>&1 | awk '/Duration/ {split($2,a,":");print a[1]*3600+a[2]*60+a[3]}'
    
//frames
    
ffmpeg -i INPUT -vcodec copy -f rawvideo -y /dev/null 2>&1 | tr ^M '\n' | awk '/^frame=/ {print $2}'|tail -n 1

    I don’t want to execute ffmpeg 3 times to get this information ; I’d prefer to just use ffprobe.

    So... is there an elegant way to get the extra info that is not always present inside the ffprobe output (fps, frames, duration) ???

    In the preview i want to be able to jump correctly to a specific frame (NOT TIME). if the above parameters are aviable i can do that using this command.

    ffmpeg -i INPUT -vf 'select=gte(n\,FRAMENUMBER)' -vframes 1 -f image2 OUTPUT

    using the above command by setting the framenumber to the last frame always returns a black frame.
    if there are 50 frames (for example) the range is 1-50 — correct ? Frame 50 is black, frame 1 is ok, frame 0 returns an error...

    2. WHILE READING THE LOG HOW TO SKIP ERRORS AND DETERMINE IF THE CONVERSION IS FINISHED ?

    I’m able to upload one single video per time (per page) and i can read the current progress from the ffmpeg generated output log until i don’t close the page. more control/multiple conversions would be nice.

    i’m reading the last line of the log with a custom tail function but as this is a log that also includes errors i don’t always get a nice line containing the desidered values. btw to check if the progress is complete i check if the last line CONTAINS the WORD frame ....

    How can i find out when the conversion progress is finished ?

    maybe a way to delete the log with ffmpeg command ??And skip/log the errors ??

    i’m using server sent events to read the log...
    here is the php code

    <?php
    
setlocale(LC_CTYPE, "en_US.UTF-8");
    
function tailCustom($filepath,$lines=1,$adaptive=true){
    
 // a custom function to get the last line of a textfile.
    
}
    
function send($data){
    
 echo "id: ".time().PHP_EOL;
    
 echo "data: ".$data.PHP_EOL;
    
 echo PHP_EOL;
    
 ob_flush();
    
 flush();
    
}
    
header('Content-Type: text/event-stream');
    
header('Cache-Control: no-cache');
    
while(true){
    
 send(tailCustom($_GET['log'].".log"));
    
 sleep(1);
    
}
    
?>

    And here the SSE js

    function startSSE(fn){
    
 sse=new EventSource("ffmpegProgress.php?log="+encodeURIComponent(fn));
    
 sse.addEventListener('message',conversionProgress,false);
    
}
    
function conversionProgress(e){
    
 if(e.data.substr(0,6)=='frame='){
    
  inProgress=true;
    
  var x=e.data.match(/frame=\s*(.*?)\s*fps=\s*(.*?)\s*q=\s*(.*?)\s*size=\s*(.*?)\s*time=\s*(.*?)\s*bitrate=\s*(.*?)\s*$/);
    
  x.shift();x={frame:x[0]*1,fps:x[1]*1,q:x[2],size:x[3],time:x[4],bitrate:x[5]};
    
var elapsedTime = ((new Date().getTime()) - startTime);
    
var chunksPerTime = timeString2ms(x.time) / elapsedTime;
    
var estimatedTotalTime = duration / chunksPerTime;
    
var timeLeftInSeconds = Math.abs(elapsedTime-(estimatedTotalTime*1000));
    
var withOneDecimalPlace = Math.round(timeLeftInSeconds * 10) / 10;
    
  conversion.innerHTML='Time Left: '+ms2TimeString(timeLeftInSeconds).split('.')[0]+'<br />'+
    
  'Time Left2: '+(ms2TimeString(((frames-x.frame)/x.fps)*1000)+(timeString2ms(x.time)/(duration*1000)*100|0)).split('.')[0]+'<br />'+
    
  'Estimated Total: '+ms2TimeString(estimatedTotalTime*1000).split('.')[0]+'<br />'+
    
  'Elapsed Time: '+ms2TimeString(elapsedTime).split('.')[0];
    
 }else{
    
  if(inProgress){
    
   sse.removeEventListener('message',conversionProgress,false);
    
   sse.close();
    
   sse=null;
    
   conversion.textContent='Finished in '+ms2TimeString((new Date().getTime()) - startTime).split('.')[0];
    
   //delete log/old file??
    
   inProgress=false;
    
  }
    
 }
    
}

    EDIT

    HERE IS A SAMPLE OUTPUT after detecting h264 codec in a m2ts with ac3 audio

    As most devices can already read h264 i just need to convert the audio in aac and copy the same audio AC3 as second track. and put everything inside a mp4 container. So that i have a Android/chrome/ios & more browsers compatible file.

  • Android recorded video getting rotated after using ffmpeg

    6 novembre 2014, par Vaeianor

    I’m developing an android app, in which users can record a video, trim it, and then upload it to my server. I’m using the MediaRecorder class to handle the recording and using ffmpeg to trim the recorded video. The problem I’m having with ffmpeg is that the video is always getting rotated either 90 or 180 degrees after being trimmed. I know I can add a video filter (transpose=1) within the ffmpeg command to rotate the video. But that will require re-encoding the video. In my case, I don’t want to re-encode the video,as it takes too long. Instead, I’m having "-vcodec:copy" within ffmpeg command to use the same video codec.

    Because I’m setting an orientation hint to the media recorder, the media recorder always adds "rotate=90" or "rotate=180" to the video metadata. I think that’s why the video is always getting rotated by ffmpeg.
    So I was wondering if there is a way to rotate the video without re-encoding it. Or if there is a way to modify the metadata(rotate) of a recorded video before trimming it with ffmpeg.

    Please help ! The problem has been driving me crazy...

    Thanks in advance !

    Here is the ffmpeg command :

    /data/data/com.xxx.xxx/app_bin/ffmpeg -y -ss 00:00:00 -t 4.000000 -i    file:/storage/sdcard0/Movies/xxx/vid.mp4 -vcodec copy -acodec copy -metadata:s:v:0 rotate=0 -  strict -2 file:/storage/sdcard0/Movies/xxx/vid_new.mp4

  • how is the 'response' parameter calculated for rtsp authentication ?

    11 septembre 2015, par zcaudate

    So I’ve captured a couple of packets from ffmpeg to a ip camera with rtsp, which I’ve attached at the end of the question :

    In the second request/response pair, the protocol sees that it needs authentication and returns a nonce="be129bc71fa3ddfbff9989ed6f748268" to the user

    In the third request/response pair, there is a response="da0882d360a56deef2994d8ba0de8e89" being sent to the server and I’m not sure how that is generated. The user/password pair is admin with a blank password.

    Any ideas of where to look in the RFCs would be great
