  • Stream mp4 videos in different languages (ExpressJs)

    23 mars 2021, par Bennet

    I use the following code to stream videos (just in my local network). In my mp4 files are several audio tracks with different languages. Is it possible to select a specific audio track to stream ? For example, that you specify a language as query parameter in the URL, and the streamed video has the selected audio track.

    


    Example 1 :
    
URL : "localhost/video ?lang=en"
    
Video : English audio track

    


    Example 2 :
    
URL : "localhost/video ?lang=de"
    
Video : German audio track

    


    Maybe you can remove all unneeded audio tracks in the stream with ffmpeg (https://www.npmjs.com/package/ffmpeg) ?

    


    Working expressjs code/example :

  • How can I call m3u8 with multiple audio

    26 février 2020, par desmeit

    I have the following playlist.m3u8 with multiple audio :

    #EXTM3U
    
#EXT-X-VERSION:3
    

    
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio",LANGUAGE="fr",NAME="France",AUTOSELECT=NO,URI="fr/test.m3u8"
    
 #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio",LANGUAGE="en",NAME="English",AUTOSELECT=NO,URI="en/test.m3u8"
    

    
#EXT-X-STREAM-INF:BANDWIDTH=800000,RESOLUTION=360x640,AUDIO="audio"
    
640p.m3u8
    
#EXT-X-STREAM-INF:BANDWIDTH=1400000,RESOLUTION=480x842,AUDIO="audio"
    
842p.m3u8
    
#EXT-X-STREAM-INF:BANDWIDTH=2800000,RESOLUTION=720x1280,AUDIO="audio"
    
1280p.m3u8
    
#EXT-X-STREAM-INF:BANDWIDTH=5000000,RESOLUTION=1080x1920,AUDIO="audio"
    
1920p.m3u8

    if I only call the URL http://XXX.playlist.m3u8, the french audio file is played automatically. I know that the selection of the language in the native player at Apple is displayed like this :

    enter image description here

    Is there an additional possibility to select the language for example by parameters ?

    http://XXX.playlist.m3u8?LANGUAGE=DE for example

    And is it possible to run two audio files in parallel ?

  • How to transfer FFmpeg's AVPacket to CUVID's CUVIDSOURCEDATAPACKET ? or how to use FFmpeg's CUVID,any demo ?

    17 mars 2017, par San

    As the title said,I was trapped to How to transfer FFmpeg’s AVPacket to CUVID’s CUVIDSOURCEDATAPACKET,and my main code about this question is below :`

    AVPacket* avpkt;
    
avpkt = (AVPacket*)av_malloc(sizeof(AVPacket));
    
CUVIDSOURCEDATAPACKET cupkt;
    
int iPkt = 0;
    
while (av_read_frame(pFormatCtx, avpkt) >= 0) {
    
    if (avpkt->stream_index == videoindex) {
    

    
        cuCtxPushCurrent(g_oContext);
    

    
        if (avpkt && avpkt->size) {
    
            cupkt.payload_size = (unsigned long)avpkt->size;
    
            cupkt.payload = (const unsigned char*)avpkt->data;
    

    
            if (avpkt->pts != AV_NOPTS_VALUE) {
    
                cupkt.flags = CUVID_PKT_TIMESTAMP;
    
                if (pCodecCtx->pkt_timebase.num && pCodecCtx->pkt_timebase.den) {
    
                    AVRational tb;
    
                    tb.num = 1;
    
                    tb.den = AV_TIME_BASE;
    
                    cupkt.timestamp = av_rescale_q(avpkt->pts, pCodecCtx->pkt_timebase, tb);
    
                }
    
                else
    
                    cupkt.timestamp = avpkt->pts;
    
            }
    
        }
    
        else {
    
            cupkt.flags = CUVID_PKT_ENDOFSTREAM;
    
        }
    

    
        oResult = cuvidParseVideoData(hParser_, &cupkt);
    
        if ((cupkt.flags & CUVID_PKT_ENDOFSTREAM) || (oResult != CUDA_SUCCESS)) {
    
            break;
    
        }
    
        iPkt++;
    
        printf("Succeed to read avpkt %d !\n", iPkt);
    
        checkCudaErrors(cuCtxPopCurrent(NULL));
    
    }
    
    av_free_packet(avpkt);
    
}

    and as you see,the code

    cupkt.payload_size = (unsigned long)avpkt->size;
    
cupkt.payload = (const unsigned char*)avpkt->data;

    needs to be corrected。
    I’m poor at english,I hope I have expressed my self clearly。
