I am able to create m3u8 file using ffmpeg from rtmp live but not able to play the file in html5 video tag & apple device

3 janvier 2014, par Nikita

I am able to create the m3u8 file by following steps :

1.Execute ffmpeg -v verbose -i rtmp://<host>:<port>/<stream> -c:v libx264 -c:a aac -ac 1 -strict -2 -crf 18 -profile:v baseline -maxrate 400k -bufsize 1835k -pix_fmt yuv420p -flags -global_header -hls_time 10 -hls_list_size 6 -hls_wrap 10 -start_number 1 <pathtofolderyouwantto>/<streamname>.m3u8

</streamname></pathtofolderyouwantto></stream></port></host>

2.Make that folder you just mentioned on ffmpeg command () to be accessible by an http url.

3.Create a simple html page to play :

<video controls="controls" width="480" height="270" src="<streamName>.m3u8"></video>

But not able to play using html5 video tag as well as in apple device.

following is my ffmpeg console output :

FFMPEG - ignoring invalid SAR : 0/0

10 septembre 2015, par Sultanen

Im using FFMPEG to merge multiple IP cameras streams into one MPEG stream. This works well for some cameras but i get this error message when i stream a DLink MJPEG stream :

[mjpeg @ 0x7fd0f900b600] ignoring invalid SAR: 0/000:00.26 bitrate=2673.8kbits/s dup=1 drop=907    

    Last message repeated 12 times

[mjpeg @ 0x7fd0f900b600] ignoring invalid SAR: 0/000:00.26 bitrate=2673.8kbits/s dup=1 drop=947

The ffmpeg command i use is :

ffmpeg \

-i http://admin:@IP1/video.cgi?resolution=640x480 \

-i http://admin:@IP2/video.cgi?resolution=640x480 \

-filter_complex "[0:v]scale=320:240,pad=640:480[a]; [1:v]scale=320:240[b];[a][b]overlay=320[out]" \

-map [out] \

-f mpeg1video \

-r 30 http://outputURL \

ffprobe gives me the following information about the stream

[mjpeg @ 0x7fe20b80c000] Format mjpeg detected only with low score of 25, misdetection possible!

[mjpeg @ 0x7fe20c000000] ignoring invalid SAR: 0/0

Input #0, mjpeg, from 'http://admin:@IP1/video.cgi?resolution=640x480':

  Duration: N/A, bitrate: N/A

    Stream #0:0: Video: mjpeg, yuvj420p(pc, bt470bg/unknown/unknown), 640x480, 25 tbr, 1200k tbn, 25 tbc

What does this mean and how can i avoid it ?

FFmpeg av_guess_format returns NULL

12 septembre 2014, par Kage
I’m following the example code here : http://cekirdek.pardus.org.tr/ ismail/ffmpeg-docs/output-example_8c-source.html

My code is as follows :
```
fmt = av_guess_format(NULL, filename, NULL);

if (!fmt) {

        LOGE(1,"Could not deduce output format from file extension: using MPEG.\n");

        fmt = av_guess_format("mp4", NULL, NULL);

}

    if (!fmt) {

        LOGE(1, "Could not find suitable output format\n");

        exit(1);

}
```
The two times that I call av_guess_format, it is returning NULL both times.
I am calling both av_register_all() and avcodec_register_all() beforehand.

Any ideas as to why this is returning NULL ?

Thanks in advance.
