Compress video FFMPEG doesn't work

13 février 2018, par Douglas Anunciação

I’m trying to compress video using FFMPEG and this library : https://github.com/guardianproject/android-ffmpeg-java

I imported ffmpeglib as a module in my project. This is the code is use to compress :

public class MainActivity extends Activity {



    private ArrayList&lt;Object&gt; listVideoPaths = new ArrayList&lt;&gt;();<br />

<br />

    @Override<br />

    protected void onCreate(Bundle savedInstanceState) {<br />

        super.onCreate(savedInstanceState);<br />

        setContentView(R.layout.activity_main);<br />

<br />

        getGalleryVideos();<br />

<br />

        File videoFolderFile = new File(&quot;/storage/emulated/0/DCIM/Camera/&quot;);<br />

<br />

        if(videoFolderFile.exists())<br />

            Log.e(&quot;TEST FFMPEG&quot;, &quot;video folder exist&quot;);<br />

        else<br />

            Log.e(&quot;TEST FFMPEG&quot;, &quot;video folder DON'T exist&quot;);<br />

<br />

<br />

        File videoInputFile = new File(listVideoPaths.get(0).toString());<br />

<br />

        if(videoInputFile.exists())<br />

            Log.e(&quot;TEST FFMPEG&quot;, &quot;video input file exist&quot;);<br />

        else<br />

            Log.e(&quot;TEST FFMPEG&quot;, &quot;video input file DON'T exist&quot;);<br />

<br />

        File videoOutputFile = new File(videoFolderFile,&quot;output.mp4&quot;);<br />

<br />

        if(videoOutputFile.exists())<br />

            Log.e(&quot;TEST FFMPEG&quot;, &quot;video output file exist&quot;);<br />

        else<br />

            Log.e(&quot;TEST FFMPEG&quot;, &quot;video output file DON'T exist&quot;);<br />

<br />

        FfmpegController ffmpegController;<br />

<br />

        try {<br />

            ffmpegController = new FfmpegController(this,videoFolderFile);<br />

<br />

            Clip mediaIn = new Clip();<br />

<br />

            mediaIn.path = videoInputFile.getAbsolutePath();<br />

<br />

            mediaIn.videoFps =  &quot;25&quot;;<br />

<br />

            ffmpegController.convertToMPEG(mediaIn, videoOutputFile.getAbsolutePath(), new ShellUtils.ShellCallback() {<br />

                    Log.e(&quot;TEST FFMPEG&quot;, &quot;shellOut - &quot; + shellLine);<br />

                }<br />

<br />

                @Override<br />

                public void processComplete(int exitValue) {<br />

                    Log.e(&quot;TEST FFMPEG&quot;, &quot;proccess complete - &quot; + exitValue);<br />

                }<br />

            });<br />

<br />

<br />

        } catch (IOException e) {<br />

            e.printStackTrace();<br />

        } catch (Exception e) {<br />

&lt;/code&gt;&lt;/pre&gt;<br />

&lt;p&gt;I get no error but the video doesn't play. The log file is:&lt;/p&gt;<br />

FFmpeg image to video conversion error : [image2] Opening file for reading

14 février 2018, par user1690179

I am running ffmpeg on an AWS Lambda instance. The Lambda function takes an input image and transcodes it into a video segment using ffmpeg :

ffmpeg -loop 1 -i /tmp/photo-SNRUR7ZS13.jpg -c:v libx264 -t 7.00 -pix_fmt yuv420p -vf scale=1280x720 /tmp/output.mp4

I am seeing inconsistent behavior where sometimes the output video is shorter than the specified duration. This happens inconsistently to random images. The same exact image sometimes renders correctly, and sometimes is cut short.

This behavior only happens on Lambda. I am not able to replicate this on my local computer, or on a dedicated EC2 instance with the same environment that runs on lambda.

I noticed that when the output video is short, the ffmpeg log is different. The main difference are repeated [image2 @ 0x4b11140] Opening '/tmp/photo-2HD2Z3UN3W.jpg' for reading lines. See ffmpeg logs below.

Normal execution with the correct output video length :

    ffmpeg -loop 1 -i /tmp/photo-SNRUR7ZS13.jpg -c:v libx264 -t 7.00 -pix_fmt yuv420p -vf scale=1280x720 /tmp/video-TMB6RNO0EE.mp4

As requested, here is a link to the full log. In this log - ffmpeg renders only 323 out of 375 frames.

The Opening '/tmp/photo-2HD2Z3UN3W.jpg' segment repeats many many times until it finally renders out a short video. Does anyone have insight into why it keeps opening the image file ? This must have something to do with the underlying issue.

FFmpeg - feed raw frames via pipe - FFmpeg does not detect pipe closure

8 septembre 2018, par Rumble

Im trying to follow these examples from C++ in Windows. Phyton Example C# Example

I have an application that produces raw frames that shall be encoded with FFmpeg.
The raw frames are transfered via IPC pipe to FFmpegs STDIN. That is working as expected, FFmpeg even displays the number of frames currently available.

The problem occours when we are done sending frames. When I close the write end of the pipe I would expect FFmpeg to detect that, finish up and output the video. But that does not happen. FFmpeg stays open and seems to wait for more data.

I made a small test project in VisualStudio.

As you can see in the last line of te FFmpeg output, the images got trough. 10 frames are available. But after closing the pipe, FFmpeg does not close, still expecting input.

As the linked examples show, this should be a valid method.

Trying for a week now...
