  • Use ffmpeg to stream live content to azure media services

    9 juin 2016, par Dadicool

    I've been trying to stream content to azure media services using ffmpeg as it's one of the options described here : http://azure.microsoft.com/blog/2014/09/18/azure-media-services-rtmp-support-and-live-encoders/

    My command is :

    ffmpeg -v verbose -i 300.mp4 -strict -2 -c:a aac -b:a 128k -ar 44100 -r 30 -g 60 -keyint_min 60 -b:v 400000 -c:v libx264 -preset medium -bufsize 400k -maxrate 400k -f flv rtmp://nessma-****.channel.mediaservices.windows.net:1935/live/584c99f5c47f424d9e83ac95364331e7

    I have made sure that the streaming endpoint has one active streaming unit, I also made sure that the channel is actually Ready and I even get it to start streaming (which makes a PublishURL available).

    When I execute the ffmpeg command to start streaming, I keep getting the following error :

    The Azure blog post clearly states that this should be possible but I can't find a working example anywhere.

    Environment :

    • MacOS Maverick
    • FFMPEG installed from official build
    • 300.mp4 : 1080p trailer of the latest 300 movie

  • Cannot wrie header FFMPEG

    9 juin 2016, par Van Gan

    I'm working on a Project with FFMPEg, but somehow i cannot creae any media file. I've set the Parameters, codec etc. but when i call avformat_write_header the app just stops working. Here's my code:

    AVOutputFormat *fmt;
AVCodecContext *codecctx;
AVFormatContext *fmtctx;
fmt=av_guess_format(NULL,filename,NULL);
    AVCodec *codec = avcodec_find_encoder(fmt->video_codec);
codecctx = avcodec_alloc_context3(codec);
codecctx->codec_id = fmt->video_codec;
codecctx->codec_type = AVMEDIA_TYPE_VIDEO;
codecctx->gop_size = 12;
codecctx->bit_rate = WIDTH*HEIGHT*4;
codecctx->width = WIDTH;
codecctx->height = HEIGHT;
codecctx->time_base.den = 2;  
codecctx->time_base.num =1;
//codecctx->time_base =(AVRational){1,FPS};
codecctx->max_b_frames=1;
codecctx->pix_fmt= STREAM_PIX_FMT;
fmtctx = avformat_alloc_context();
fmtctx->oformat = fmt;
fmtctx->video_codec_id = fmt->video_codec;
avcodec_open2(codecctx, codec, NULL);
    AVStream *VideoStream = avformat_new_stream(fmtctx,codec);  
avformat_write_header(fmtctx,NULL);

  • ffmpeg : Combine/merge multiple mp4 videos - not working

    9 juin 2016, par dtbaker

    Here is the command I am using to combine multiple videos:

    ffmpeg -i 75_540_38HQ2.mp4 -i 76_70_20.mp4 -i 76_173_80.mp4 -i 81_186_35.mp4 -vcodec copy -acodec copy Mux1.mp4

    The resulting Mux1.mp4 does not contain all videos. Only the first video (75_540_38HQ2.mp4). The file size of the source and resulting video is below (as you can see, resulting video is slightly larger than first vid):

    $ ls -lh
-rw-r--r-- 1 dbaker dbaker  42M 2011-03-24 11:59 75_540_38HQ2.mp4
-rw-r--r-- 1 dbaker dbaker 236M 2011-03-24 12:09 76_173_80.mp4
-rw-r--r-- 1 dbaker dbaker  26M 2011-03-24 12:05 76_70_20.mp4
-rw-r--r-- 1 dbaker dbaker  54M 2011-03-24 12:15 81_186_35.mp4
-rw-r--r-- 1 dbaker dbaker  44M 2011-03-24 14:48 Mux1.mp4

    Here is the output of the ffmpeg command. To me it looks ok, showing the multiple source inputs and the single output.

    Am I doing something blindingly stupid here?

    The source videos came from a video camera, and are small snippets taken with ffmpeg -i bigfile.mp4 -ss 20 -t 10 -vcodec copy etc..

    Thanks heaps!! Dave

    Edit: couldn't solve it so I just use avidemux GUI tool. It seemed to append the MP4's just fine.

    Must be a problem with MP4's or just the ones that come off a gopro camera.

  • Conversion of .iva to .mp4 using ffmpeg

    9 juin 2016, par Rupesh Parab

    The video which I am trying to convert is uploaded at http://www.filedropper.com/video_17

    I am using the following command to convert the file:

    ffmpeg -i archive.iva -c copy -map 0 output.mp4 -vsync 2 -y;

    The file should be around 1 min in length but after conversion is of only 7 secs

    What am I doing wrong?
