    22 avril 2018, par zpc

    The duration of source video and subtracted wav audio is different , why ?

    I’m recorgnizing subtitle from audio, and I need to add subtitle back to video. So I want the duration of audio and video the same.

    ffmpeg -i http://cdn.live.360.cn/huikan_news/vod-media/_XW_203286B417B7C6466B3B_20160627185953.m3u8 -vn test.wav -y

  • Choose download resolution in m3u8 list with ffmpeg

    31 mars 2024, par Bruno Andrade

    I'm trying to download video from a m3u8 playlist using ffmpeg but I do not know how to choose the resolution to download. Currently the command is downloading the highest version

    



    the command I am using is :

    



    /home/user/bin/ffmpeg -user_agent "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:49.0) Gecko/20100101 Firefox/49.0" -i "https://sitevideo.com/list.m3u8" -c copy "/home/file/video.ts"


    



    My list is this

    



    #EXTM3U
#EXT-X-VERSION:3
#EXT-X-STREAM-INF:BANDWIDTH=400000,NAME="low"
size1.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=800000,NAME="med"
size2.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=1900000,NAME="best"
size3.m3u8


    


  • Not able to change the program number for the video

    17 mai 2018, par C.B. Akshay Kumar

    I have been trying to change the program number of a particular .ts file using FFmpeg without any success. I saw the documentation and it mentions to use the -program option. But, I am not able to add the streams as I desire. Here’s the program information for the stream that I possess currently :

    Input #0, mpegts, from 'output_2_without_pgm_num.ts':
    
  Duration: 00:01:49.92, start: 1.400000, bitrate: 1816 kb/s
    
  Program 1
    
    Metadata:
    
  service_name    : Service01
    
  service_provider: FFmpeg
    
Stream #0:0[0x100]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv, progressive), 720x576 [SAR 64:45 DAR 16:9], 25 fps, 25 tbr, 90k tbn, 50 tbc
    
Stream #0:1[0x101](ger): Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, fltp, 384 kb/s (clean effects)
    
Stream #0:2[0x102](eng): Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, fltp, 384 kb/s (clean effects)
    
Stream #0:3[0x103](ger): Subtitle: dvb_teletext ([6][0][0][0] / 0x0006)

    Now, I want to change the program number from 1 to 22. Any idea how I could do that ? I have tried using -program option, but I can’t add streams 2 and 3 to the newly created .ts file.

    Thanks in advance !
