  • Creating farms of unique websites

    13 avril 2011, par

    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Is it possible to change resolution in second pass for ffmpeg multipass encodes ;x264 and x265 ?

    30 mai 2017, par Karthik M

    I have been using the following commands for two pass encodes

    ffmpeg -i <input /> -c:v libx265 -x265-params pass=1:crf=22 -f mp4 /dev/null
    
ffmpeg -i <input /> -c:v libx265 -x265-params pass=2 <output>
    
</output>

    If i try changing resolution in second pass with vf scale

    ffmpeg -i <input /> -vf scale=720:-2 -c:v libx265 -x265-params pass=2 <output>
    
</output>

    i get `

    [Error]CU-tree frame type 87 doesn’t match actual frame type 0.

    `

    EDIT 1 : x264 and x265 have been around for years did someone not find a solution/hack to having multiple output resolutions using stats from first pass at a different resolution, atleast bitrate distribution would look same i presume

  • How to transcode a video to custom resolution using Xamarin.MP4Transcoder.Transcoder

    12 mai 2017, par Prashant

    I need to transcode a video to 640*480 resolution using Xamarin.MP4Transcoder.Transcoder. Currently there are 2 available resolutions 720pFormat and 960x540Format. There is a method called Transcoder For (IMediaFormatStrategy strategy) available in Transcoder class.

    I can create MediaFormat object with MIME Type, Width and Height
    by below mentioned code snippet :

    MediaFormat obj = MediaFormat.CreateVideoFormat("video/mp4", 480, 640);


    but the problem is how can assign it to IMediaFormatStrategy or is there any other way to achieve this.

    Piece of code for Transcoding a video:
    

    
Xamarin.MP4Transcoder.Transcoder.For960x540Format().ConvertAsync(inputFile, outputFile, f =>
                                {
                                  onProgress?.Invoke((int)(f * (double)100), 100);

                                  
                                } );
    

    
inputFile: Video file which needs to be transcoded.
    
outputFile: Resultant file generated after transcoding.

    For more info you can refer https://github.com/neurospeech/xamarin-android-ffmpeg

    Any help is appreciated. Thanks in advance !!

  • using ffmpeg to record highest resolution offered by Facetime cameras (mac)

    7 mai 2017, par user1361529

    I am using the following code successfully to record a video feed from my mac

    ./ffmpeg -f avfoundation -framerate 30  -i "default" out.mp4

    This however seems to be recording video at the lowest resolution of 320x200

    My camera supports the following resolutions :

    [avfoundation @ 0x7ff7b2800000] Supported modes:
    
[avfoundation @ 0x7ff7b2800000]   1280x720@[1.000000 30.000000]fps
    
[avfoundation @ 0x7ff7b2800000]   640x480@[1.000000 30.000000]fps
    
[avfoundation @ 0x7ff7b2800000]   320x240@[1.000000 30.000000]fps

    I tried manually specifying the resolution using both -s and -video_size but that seems to just scale up the low res video.

    How do I get ffmpeg to pick my 1280x720 resolution ?

    thanks
