Looks like version of FFMPEG is not compatible with this code

realrainer commented 7 years ago

FFMPEG which version are you using?

realrainer commented 7 years ago

If shared ffmpeg library libswscale.so is installed in your libdir (usually /usr/lib64) ?

Now, I'm using 3.2.2 version. But, I didn't receive video stream and image previews.

Error has gone, but looks like still doesn't work.

Also, I didn't receive any callbacks if TCP mode is off in RTSP client. Do you have ideas why?

I have changed artspclient.cpp to:

#define REQUEST_STREAMING_OVER_TCP True

After that I was able to receive callbacks in my script.

My output:

BTW, I see the error in output codec:

avcodec_open2: ERROR: Could not open output codec

That's why I don't have video stream

Some cameras not supported streaming over UDP in RTSP mode

Could you show me your top-level javascript initialisation code of aStreamDecode object? I try to run test system with your configuration May be replace pixel format to AV_PIX_FMT_YUV420P in astreamdecode.cpp:66 solves this problem:

pOutCtx->pix_fmt = AV_PIX_FMT_YUV420P;

So, I will add flag for that case. Thanks.

This is my script.

var camCount = 1;
process.env.UV_THREADPOOL_SIZE = 5 + camCount * 2;

h264stream = fs.createWriteStream("./out/stream.h264");
mpeg1stream = fs.createWriteStream("./out/stream.mpeg1video");

cam01 = new avr.aRTSPInput("rtsp://admin@10.0.1.9/h264Preview_01_main", "h264");
cam01decoder = new avr.aStreamDecode(1280, 720, 320, 180, "h264", 16, 8);
cam01decoder.needVideo(1);

cam01.start(function(buf, keyFrame) {
    if (keyFrame) {
        console.log("Got keyframe\n");
    }
    h264stream.write(buf);
    cam01decoder.decode(buf);
});

cam01decoder.onPreview(function(buf) {
    console.log("onPreview");
    thumb = fs.writeFile("./out/frames/" + Date.now() + ".jpeg", buf);
});

cam01decoder.onVideo(function(buf) {
    console.log("onVideo");
    mpeg1stream.write(buf);
});

pOutCtx->pix_fmt = AV_PIX_FMT_YUV420P;

Still doesn't work.

realrainer commented 7 years ago

I was add some error handling code, please try checkout project again and run your code. With latest ffmpeg 3.2.2 library and enabled all needed encoders and decoders error is absent.

I returned line astreamdecode.cpp:66: pOutCtx->pix_fmt = AV_PIX_FMT_YUVJ420P; try checkout and show me console output again.

Also show me result of command (to determine, which pixel format need to defined in encoder setup): ffmpeg -h encoder=mjpeg | grep pixel
