MP4 to OGG conversion does not include sound
15 juillet 2015, par iamthestreetsI found this question and I was able to successfully convert my video to OGG, but it does not include the sound.
Here is the code:
//SET FFMPEG PATH $ffmpegPath = 'ffmpeg'; //CREATE CLASS INSTANCE $ffmpegObj = new ffmpeg_movie($video); //GET AUDIO BITRATE FROM SOURCE FILE $srcAB = intval($ffmpegObj->getAudioBitRate()); //GET VIDEO BITRATE FROM SOURCE FILE $srcVB = intval($ffmpegObj->getVideoBitRate()); //SET THE AUDIO CODEC TO LIBVORBIS $aCodec = ' -acodec libvorbis'; //SET THE VIDEO CODEC TO LIBTHEORA $vCodec = ' -vcodec libtheora'; //EXECUTE THE CONVERSION exec($ffmpegPath." -i ".$video.$vCodec." -vb ".$srcVB." -ab ".$srcAB." ".$ogg_video);What am I doing wrong?

how does one loop a video using ffmpeg on android ?
15 juillet 2015, par MagicomirallesI'm using hiteshsondhi88's "FFmpeg Android Java" library and it works fine for scaling, trans-coding, and overlaying. However, when I try to loop a video I just get the same un-looped video on my output.
My code:
String internalPath = getFilesDir().getPath(); //get internal directory String command = "-y -f concat -i "+internalPath+"/myList.txt -c copy "+internalPath+"/final.mp4"; ffmpeg.execute(command, ffmpegResponseHandler);The text in "myList.txt" is generated programmatically but it looks like this:
file 'final_unlooped.mp4' file 'final_unlooped.mp4' file 'final_unlooped.mp4' file 'final_unlooped.mp4' file 'final_unlooped.mp4'Finally, the log:

This command works fine on Windows but for some reason it wont work on Android. any ideas of what it could be, or what am I doing wrong?

PHP variable into FFMPEG
14 juillet 2015, par kunali am making web tool which should be able to search the file within the Archive and then get the duration of the video with FFMPEG Code.
for search the file in the Archive , here is my code!
$command ='find /mnt/archiev/ -name '.$_POST['MXF'].'.mxf'; if (!($stream = ssh2_exec($con, $command))) { echo "fail: unable to execute command\n"; } else { $errorStream = ssh2_fetch_stream($stream, SSH2_STREAM_STDERR); $FILE = stream_get_contents($stream); / check if file exist or not and then run the Next command. if(!($FILE)) { echo "file Doesnt Exist in the Archieve. please enter the correct file ID"; ssh2_exec($con, "logout"); exit; } elseif { $commandA= ffmpeg -i '.$FILE.' 2>&1 | grep "Duration:"'; (!($stream2 = ssh2_exec($con, $command))) { echo "fail: unable to execute command\n"; } else { $errorStream2 = ssh2_fetch_stream($stream2, SSH2_STREAM_STDERR); $Duration = stream_get_contents($stream); var_dump($duration); } }My problem is this code returns me NUll value , but it supposed to return me the Duration of video!
Here $FILE has the file Path , where searched File exist but when i use this with ffmpeg code it returns
nulldoes anyone have idea how can i make it work, i need to be able to find the files within the archiev and then with
stream_get_contens()funcation i get the path of the video and this path i need to use within the FFMPEG as a input but it doesnt work and return theNULL.which suppossed to retrun the video Duration.
please help!!!
thanks in adavance.
