  • Rate-Control management in ffmpeg

    28 février 2014, par alexbuisson

    Hi I try to understand how ffmpeg wrap its rc_max_rate parameters to the x264 parameters
    and I'm wondering what the following code means ? It's a piece of code coming from ffmpeg/libavcodec/mpeg_video_enc.c but the commit log is not explicit and I don't know from where those Magic Number come from !

    So if you have an idea or an URL that can explain why those formula where implemented, it will be useful.

    if (avctx->rc_max_rate && !avctx->rc_buffer_size) {
    
        switch(avctx->codec_id) {
    
        case AV_CODEC_ID_MPEG1VIDEO:
    
        case AV_CODEC_ID_MPEG2VIDEO:
    
            avctx->rc_buffer_size = FFMAX(avctx->rc_max_rate, 15000000) * 112L / 15000000 * 16384;
    
            break;
    
        case AV_CODEC_ID_MPEG4:
    
        case AV_CODEC_ID_MSMPEG4V1:
    
        case AV_CODEC_ID_MSMPEG4V2:
    
        case AV_CODEC_ID_MSMPEG4V3:
    
            if       (avctx->rc_max_rate >= 15000000) {
    
                avctx->rc_buffer_size = 320 + (avctx->rc_max_rate - 15000000L) * (760-320) / (38400000 - 15000000);
    
            } else if(avctx->rc_max_rate >=  2000000) {
    
                avctx->rc_buffer_size =  80 + (avctx->rc_max_rate -  2000000L) * (320- 80) / (15000000 -  2000000);
    
            } else if(avctx->rc_max_rate >=   384000) {
    
                avctx->rc_buffer_size =  40 + (avctx->rc_max_rate -   384000L) * ( 80- 40) / ( 2000000 -   384000);
    
            } else
    
                avctx->rc_buffer_size = 40;
    
            avctx->rc_buffer_size *= 16384;
    
            break;
    
        }
    
        if (avctx->rc_buffer_size) {
    
            av_log(avctx, AV_LOG_INFO, "Automatically choosing VBV buffer size of %d kbyte\n", avctx->rc_buffer_size/8192);
    
        }

  • How to control output file name in a batch file ?

    24 décembre 2016, par vini_i

    I’m running a batch file to use FFMPEG to convert all the files with the *.MTS extension in a directory.

    for %%A in (*.MTS) do ffmpeg -i "%%A" -vcodec copy -acodec pcm_s16le -ar 48000 -ac 2 "newfiles\%%A.mov"
    
pause

    The output files go to a directory called newfiles. The conversion takes place with no problem. The problem is that if the input is a file name.MTS the output is a file name.MTS.mov

    How can i change the batch file so that with an input of name.MTS the output is name.mov ?
