  • swscale/aarch64 : vscale optimization

    13 août 2022, par Swinney, Jonathan
    swscale/aarch64 : vscale optimization

    Use scalar times vector multiply accumlate instructions instead of
    
vector times vector to remove the need for replicating load instructions
    
which are slightly slower.

  • 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

    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!

    What does this mean and how can i avoid it ?
