  • ffmpeg on xampp with php version 5.4++

    19 septembre 2016, par basagabi

    I am trying to install ffmpeg windows using xammp. I followed the steps stated on this website but it seems that it is not working. No errors being logged when I start apache and ffmpeg not showing on the phpinfo().

    I am not sure if this has to do with the PHP version that I have (5.5.24) since I read on a forum that ffmpeg is compatible with PHP version <= 5.3.

    I am hoping to run this with PHP version >= 5.4,

  • Getting know how much progress has ffmpeg done in C#

    29 décembre 2022, par Aenye_Cerbin

    I'm writing an app that uses ffmpeg to convert audio/video files.&#xA;I can call ffmpeg and specify it's options, I can see that it's working.&#xA;I want to be able to check how much of the job is done, so I can present it to user.&#xA;As I've read ffmpeg doesn't support any progress bar or percentage and ffmpeg console output is not very friendly, so I cannot simply show it's output to user, because it will look awful. I am not using any wrapper and do not plan to use any because I need to write my own backend that call ffmpeg and frontend to communicate with user.

    &#xA;

    I'm using System.Threading to start ffmpeg in new process, I can say if the process is running, or get it's exit code, but I don't see any way to get info about how much of the job is done. I thought I can simply measure input file size and check periodically output file size, but it won't be any accurate, because the output file will have different size depending on what codec and container we use.&#xA;I've read I can also use frame progress, but the way of obtaining it is still not clear to me. I also need to do it for audio files.

    &#xA;

    Is there any reasonable way to do so ?

  • Converting AC3 to AAC with minimal loss [on hold]

    20 juin 2016, par forthrin

    iPad does not seem to support the ac3 audio codec.

    Therefore, I am converting an mkv/h264/ac3 movie into m4v/m264/aac using ffmpeg to view it on the iPad.

    The video part is simply copied as it is ; my question is how I preserve the audio as best possible.

    1. Is there any way to do the audio conversion losslessly ?

    2. If no to question 1, what is the best way to preserve the audio quality ? If the source audio is 192 kb/s and 48000 Hz, should I simply use 192/48000 for the target too ? Or will I preserve the audio better if I increase the the bit rate somewhat ?

    3. Side question : I noticed that a lot of mkv files have rather poor audio to begin with. Will the loss of ac3/aac re-encoding be negligable compared to the initial quality loss from the source material ? And why isn’t high audio quality more of a priority for movie files ? It’s not like file sizes matter much anymore with today’s storage and bandwidth.
