  • FFMPEG audio conversion is taking too much time

    26 octobre 2018, par Sachin Varma

    How to make the audio conversion ultrafast ?

    It is now taking more than 2 minutes for converting an audio around 2mb in size.

    The command i’m using for execution of conversion is

    String[] cmd = {"-y", "-i", audioPath, outputPath};

    How to preset the ultrafast mode ?

    While i’m trying it like

    String[] cmd = {"-y", "-i", audioPath,"-preset", "ultrafast" ,outputPath};

    It is taking same time itself.

  • FFMPEG HLS Multiple audio languages with var_stream_map - EXT-X-MEDIA:TYPE doesn't contain LANGUAGE

    30 janvier 2020, par Moonsurfer_1

    I have a question involving multiple audio languages on HLS with FFMPEG.

    I’m currently using the following command to mux a transport stream with multiple audio languages into an HLS stream with a master playlist :

    ffmpeg -re -i $INPUT_URL -map 0:v -c:v copy -map 0:a -c:a copy -f hls -hls_time 6 -hls_list_size 10 -hls_flags delete_segments+program_date_time -hls_segment_filename "$FULL_OUTPUT_FOLDER/stream_%v_%d.ts" -var_stream_map "v:0,agroup:groupname a:0,agroup:groupname a:1,agroup:groupname a:2,agroup:groupname a:3,agroup:groupname" -master_pl_name master.m3u8 $FULL_OUTPUT_FOLDER/stream-%v.m3u8

    The output of this command looks like this :

stream-4.m3u8

    While this does seem to work with VLC, I need the EXT-X-MEDIA:TYPE tag to contain the LANGUAGE property. (the player I’m working with uses it to parse the audio tracks’ language) I can’t figure out how to do that based on the documentation I’ve found.

    Could anyone help me with this ?

    Thanks !

  • OpenCV 3.4.3 - GStream not called when VideoWriting

    14 décembre 2018, par taubhi

    I’d like to succeed writing a file with OpenCV encoding with GStreamer.

    Thus I’m using the code :

    VideoWriter.open("appsrc ! autovideoconvert ! omxh264enc ! matroskamux ! filesink location=test2.mkv sync=false",
    
//cv::CAP_GSTREAMER, //set or not, I get the same problem
    
0, (double)25, //fourcc, fps
    
cv::Size(1024, 1024), 
    
true);

    And my problem :

    A video file called appsrc ! autovideoconvert ! omxh264enc ! matroskamux ! filesink location=test2.mkv sync=false is created (rather than test2.mkv), and it is empty. The same problem is corrected and seems to work in the following thread, without any effect for me : Opening a GStreamer pipeline from OpenCV with VideoWriter

    I tried, without success :

    • Add quotes to the file name test2 :
      "appsrc ! autovideoconvert ! omxh264enc ! matroskamux ! filesink location=\"test2.mkv\" sync=false" neither
    • Encode with different format : .flv rather than .mkv
    • Encode with different codec : omxh265enc rather than omxh264en

    I checked :

    • That GStreamer is well compiled with OpenCV ; the CMake of the OpenCV project outputs :

      Video I/O:Video for Windows : YES
      DC1394 : NO
      FFMPEG : YES (prebuilt binaries)
      avcodec : YES (ver 57.107.100)
      avformat : YES (ver 57.83.100)
      avutil : YES (ver 55.78.100)
      swscale : YES (ver 4.8.100)
      avresample : YES (ver 3.7.0)
      GStreamer :

      base : YES (ver 1.0)

      video : YES (ver 1.0)

      app : YES (ver 1.0)

      riff : YES (ver 1.0)

      pbutils : YES (ver 1.0)

      DirectShow : YES

      Media Foundation : YES

    • That FFMpeg is installed on my computer ; for this I used VLC :

      File -> Stream -> Add a file then stream
      New destination : RTP/MPEG Transport Stream
      Profile : Video - H.264 + MP3 (MP4)
      Then no error happens ; Note : an error occured with Video - H.265 + MP3
      (MP4), but I’m using omxh264enc in my code, not 265

    I’m struggled :/ Do you have any idea ?
    Thanks a lot :)

    Have a good day,

    Thibaut
