  • How to Speed Up Two-Pass Encoding ?

    27 juillet 2017, par Matt McManis

    I have a Video file with Audio, Subtitles, Chapters, and Metadata.

    I removed Audio and Subtitles with -an -sn from -pass 1 and then inlclude them in -pass 2.

    What about for Chapters and Metadata ? And how do you apply Turbo to -pass 1 ?

    Is there anything more that can be done ?


    I have a script that will convert mpg to mp4. I’ve sorted it with linebreaks so it’s easier to read.

    Pass 1

    "C:\Videos\example.mpg"

    -vcodec libx264
    -preset medium -b:v 2500K -pix_fmt yuv420p -qcomp 0.8
    -vf scale="trunc(iw/2)*2:trunc(ih/2)*2"
    -pass 1

    -map 0:v:0? -an -sn

    -threads 8

    "C:\Videos\example.mp4"

    Pass 2

    ffmpeg -y -i

    "C:\Videos\example.mpg"

    -vcodec libx264
    -preset medium -b:v 2500K -pix_fmt yuv420p -qcomp 0.8
    -vf scale="trunc(iw/2)*2:trunc(ih/2)*2"
    -pass 2

    -acodec aac
    -b:a 320k
    -af volume=1.2

    -map 0:v:0? -map 0:a:0? -map 0:s? -c:s copy -map_metadata 0

    -threads 8

    "C:\Videos\example.mp4"

  • How to use the ffmpeg command to write the data of a .ts file into a named pipe on windows [duplicate]

    7 avril, par qyt

    I first tested creating a named pipe using C++. The code is as follows.

    


            "\\\\.\\pipe\\mpegts",
        PIPE_ACCESS_DUPLEX,  
        PIPE_TYPE_BYTE | PIPE_READMODE_BYTE | PIPE_WAIT,
        PIPE_UNLIMITED_INSTANCES,
        1024 * 1024 * 10,
        1024 * 1024 * 10,
        0,
        NULL);
    if (hPipe == INVALID_HANDLE_VALUE) {
    
    }
    Sleep(1000000);


    


    Then I tried to write data using the command :
./ffmpeg -re -stream_loop -1 -i .\1.ts -c copy -f mpegts \\.\pipe\mpegts
However, I encountered an error :

    


    File '\\.\pipe\mpegts' already exists. Overwrite? [y/N] y
[out#0/mpegts @ 0000027df35a6900] Error opening output \\.\pipe\mpegts: Permission denied
Error opening output file \\.\pipe\mpegts.
Error opening output files: Permission denied


    


    Another situation, if I input n :

    


    File '\\.\pipe\mpegts' already exists. Overwrite? [y/N] n
Not overwriting - exiting
Error opening output file \\.\pipe\mpegts


    


    and How should I solve this problem ?
