  • low quality movie with avconv

    8 novembre 2017, par masoud

    I want to create a movie from a sequence of images. I used avconv (linux System in our Company has only avconv and not ffmpeg package). to do that first I creates ’fig%0d.png’ Images and then by calling subprocess command I create a movie :

    subprocess.call('avconv -framerate 1 -f image2 -i fig%0d.png -c:v h264 -crf 1 Temp_electron1.mp4'.split())

    but the Quality of the movie is not good and more importantly the movie doesn’t Show the first Image and always starts from the second one.

    I appreciate any suggestion

  • Saving video to SD card while live streaming to YouTube using FFmpeg

    15 mai 2020, par Zohair Ul Hasan

    I'm trying to set up a Raspberry Pi so that it live streams video to YouTube using the Raspberry Pi camera and also saves the video to the SD Card for backup, in case the internet gets disconnected. I used Alex Ellis's guide to set it up, which is basically a docker image that anyone can download and set it up. He sets up the live stream to YouTube but doesn't save the video offline.

    



    So, I tinkered with his code and found that he used FFmpeg to stream to YouTube. The following line is basically the heart of his method to stream :

    



    raspivid -o - -t 0 -w 1920 -h 1080 -fps 40 -b 8000000 -g 40 | ffmpeg -re -ar 44100 -ac 2 -acodec pcm_s16le -f s16le -ac 2 -i /dev/zero -f h264 -i pipe:0 -c:v copy -c:a aac -ab 128k -g 40 -strict experimental -f flv -r 30 rtmp://a.rtmp.youtube.com/live2/$1


    



    I read up about FFmpeg and apparently, to save this stream to my SD card all I need to do is add the directory where I want to save my video to the end of this code. I modified it like so at the end of the line :

    



    raspivid -o - -t 0 -w 1920 -h 1080 -fps 40 -b 8000000 -g 40 | ffmpeg -re -ar 44100 -ac 2 -acodec pcm_s16le -f s16le -ac 2 -i /dev/zero -f h264 -i pipe:0 -c:v copy -c:a aac -ab 128k -g 40 -strict experimental -f flv -r 30 rtmp://a.rtmp.youtube.com/live2/$1 /home/pi/Desktop/my_video.mp4


    



    However, when I ran this, the terminal threw this error :

    



    /home/pi/Desktop/my_video.mp4: No such file or directory


    



    This path, however, definitely exists by default in all Raspberry Pi's. I'm not sure what's wrong here, can someone please help me out ?

    



    P.S : as an additional side question, I read up the documentation on FFmpeg and it specifically says not to use the -re argument when using a live input source, but Alex uses it anyways. Should I substitute it with something different ? It works fine right now though.
