  • Streaming by ffserver and ffmpeg on RaspberryPi

    15 septembre 2018, par saitoib

    I want to ditribute the video of the UVC Camera on Rpsberry Pi
    I edited /etc/ffserver.conf as follows.

    HTTPPort 8090
    
HTTPBindAddress 0.0.0.0
    
MaxHTTPConnections 20

</stream>

    Then, I started ffserver
    Next, I executed the following command

    ffmpeg -f v4l2 -s 1280x720 -i /dev/video0 -ac 1 -f alsa -i hw:1,0 http://localhost:8090/feed1.ffm

    I requested 192.168.12.101 : 8090 / test.mpeg from FireFox on the same network,
    but no video is displayed and a program to open or a file save dialog opens.

    What should I do ?

  • Best way to convert .ts file to mp4 or bufferedimage[] java

    23 septembre 2018, par thekevshow

    I have an m3u8 file returning .ts file polls for streaming. Regardless, how would I convert that to an array of buffered images or something else that can be easily scraped for a buffered image. Mainly just looking for direction, as I am struggling to understand each piece there. Anything is appreciated.

  • FFMpeg command to convert from avi to mp4 in php script

    16 septembre 2018, par user27240

    ffmpeg command to convert from avi file to mp4 file below does create mp4 file, but the quality of it is not all right at all. Fist, the sizes of the files are different, the mp4 is much smaller and about 1/10 of the avi file.
    Second, the playing time of the newly created mp4 is short lasting about 0.1 seconds where the avi file lasts about 60 seconds.

    Can anyone please help me out for the ffmpeg command to create mp4 file from avi under the directory like below ?

    for i in /xxxxxxx/xxxxxxx/*.avi; do
    
    ffmpeg -i "$i" -frames:v 1  "/xxxxxxx/xxxxxxx/$(basename "$i" .avi).mp4"
    
done    

    Log after the attempt :

    [root@server-xxxxxxx-x ~]# for i in /xxxxxx/xxxxxxx/xxxxxxx/*.avi; do ffmpeg -i "$i" -pix_fmt yuv420p -movflags +faststart "/xxxxxx/xxxxxxx/xxxxxxx/$(basename "$i" .avi).mp4"; done
