  • FFMPEG: How to chose a stream from all stream

    3 March 2016, by combo_ci

    I try to convert a UDP stream (that genrated from DVB signal) to HLS m3u8 file with this code:

    ffmpeg -i udp://239.1.2.1:60001 -acodec aac -strict -2 -vcodec libx264 -hls_wrap 100 -f hls /var/www/html/ts/1.m3u8

    UDP stream contain 1 channel (in this case IRIB-TV1).

    When i run this code ffmpeg detect all of service and channel that streamed from DVB card with this message:

    Input #0, mpegts, from 'udp://239.1.2.1:60001':
    Duration: N/A, start: 77906.812644, bitrate: N/A
    Program 101
    Metadata:
     service_name    : IRIB-TV1
     service_provider: IRIB
    Stream #0:0[0x3f2]: Video: h264 (Main) ([27][0][0][0] / 0x001B), yuv420p(tv, bt470bg), 720x576 [SAR 12:11 DAR 15:11], 25 fps, 50 tbr, 90k tbn, 50 tbc
    Stream #0:1[0x3f3](per): Audio: aac_latm ([17][0][0][0] / 0x0011), 48000 Hz, stereo, fltp
    Program 102
    Metadata:
     service_name    : IRIB-TV2
     service_provider: IRIB
    Program 103

     service_provider: IRIB
    Program 104
    Metadata:
     service_name    : IRIB-TV4
     service_provider: IRIB

    As you see ffmpeg finf 4 channel in UDP stream, But VLC play only channel 1(IRIB-TV1).

    Now i have have 2 question:

    1-Can I get all channel and service via this ffmpeg code?

    2-Can i choose a spesial stream from this ffmpeg code?(i know that ffmpeg can choose a stream with -map otion but i want to choose other service_name that in output log)

    output file is :

  • FFMPEG: How to chose a stream from all stream

    17 January 2020, by Ali

    I try to convert a UDP stream (that genrated from DVB signal) to HLS m3u8 file with this code:

    ffmpeg -i udp://239.1.2.1:60001 -acodec aac -strict -2 -vcodec libx264 -hls_wrap 100 -f hls /var/www/html/ts/1.m3u8

    UDP stream contain 1 channel (in this case IRIB-TV1).

    When I run this above code, ffmpeg detect all of service and channel that streamed from DVB card with this message:

    Input #0, mpegts, from 'udp://239.1.2.1:60001':
    Duration: N/A, start: 77906.812644, bitrate: N/A

    As you see ffmpeg finf 4 channel in UDP stream, But VLC play only channel 1(IRIB-TV1).

    Now I have have 2 question:

    1-Can I get all channel and service via this ffmpeg code?

    2-Can I choose a special stream from this ffmpeg code?(I know that ffmpeg can choose a stream with -map option but I want to choose other service_name that in output log)

    output file is :

  • How to make multiple edits to a single video file, and then encode once in ffmpeg?

    4 June 2022, by Edesem

    I simply want to be able to do actions such as trimming videos and concatenate videos possibly mulitples times for one video file without encoding each time, and then finally at the end encode once. This would be similar to how normal video editors work where you can make all the edits first and then encode at the end?

    


    Is this possible? Alternatives? Currently it is very inefficient and bad for quality that if I want to cut out some parts of a video I have to wait for it to reencode and then do the next edit one after the other.

    


    Thank you.
