  • FFMPEG screen grab of windows desktop and then exporting to multiple bandwidth ts and m3u8 files with master playlist

    26 juillet 2018, par Tank Daniels

    Forgive me as this is my first post as I’m really stuck and need help. My boss needs me to screen capture a windows desktop as input and be able to output at least four outputs dependent on bandwidth. Each output "Stream"(im guessing is the right terminology) must have its own .ts files and .m3u8 files, along with a master m3u8 playlist that lists the four individual m3u8 files.

    Every attempt ive made only produces a master m3u8 file with a single listing of an output stream. (Code enclosed below).

    The end result I need to produce is to have a master m3u8 that can go into a webpage that can stream mp4 hls of the users screen grab and that video output will be changed dependant upon the users bandwidth available. If you can please help me with any advice I will be eternally grateful as I need to impress my new boss in my new job, and I’ve been working on this for ages now with no joy.

    Example :
    This is what I need it to look like.

    What the M3U8 needs to look like

    Example :
    This is what it actually looks like now.

    What the current M3U8 actually looks like when i run my code

    Below is the code I am currently using. Please help.

    ffmpeg -f dshow -i video="UScreenCapture":audio="virtual-audio-capturer" -master_pl_name master.m3u8 -master_pl_publish_rate 30 -tune fastdecode -vf scale=w=640:h=360:force_original_aspect_ratio=decrease -c:a aac -ar 48000 -c:v h264 -crf 20 -sc_threshold 0 -g 48 -keyint_min 48 -hls_time 4 -hls_playlist_type vod  -b:v 800k -maxrate 856k -bufsize 1200k -b:a 96k -hls_segment_filename 360p_%03d.ts 360p.m3u8 -master_pl_name master.m3u8 -master_pl_publish_rate 30 -vf scale=w=842:h=480:force_original_aspect_ratio=decrease -c:a aac -ar 48000 -c:v h264 -crf 20 -sc_threshold 0 -g 48 -keyint_min 48 -hls_time 4 -hls_playlist_type vod -b:v 1400k -maxrate 1498k -bufsize 2100k -b:a 128k -hls_segment_filename 480p_%03d.ts 480p.m3u8 -master_pl_name master.m3u8 -master_pl_publish_rate 30 -vf scale=w=1280:h=720:force_original_aspect_ratio=decrease -c:a aac -ar 48000 -c:v h264 -crf 20 -sc_threshold 0 -g 48 -keyint_min 48 -hls_time 4 -hls_playlist_type vod -b:v 2800k -maxrate 2996k -bufsize 4200k -b:a 128k -hls_segment_filename 720p_%03d.ts 720p.m3u8 -master_pl_name master.m3u8 -master_pl_publish_rate 30 -vf scale=w=1920:h=1080:force_original_aspect_ratio=decrease -c:a aac -ar 48000 -c:v h264 -crf 20 -sc_threshold 0 -g 48 -keyint_min 48 -hls_time 4 -hls_playlist_type vod -b:v 5000k -maxrate 5350k -bufsize 7500k -b:a 192k -hls_segment_filename 1080p_%03d.ts 1080p.m3u8

  • Corrupted file when recording using ffmpeg [migrated]

    11 septembre 2015, par n179911

    I am trying to record video from my desktop ran Windows. I have a USB WebCam connected to my desktop. Sometimes, I get a mp4 file which I can play using VLC. But sometimes, I can’t play mp4 file at all (the file size seems valid video file, 37,528KB).

    Here is the command I used :

    ffmpeg -rtbufsize 1500M -y -f vfwcap -i 0 output.mp4

    I would like to know
    * why I get a corrupted file sometime with the above command
    * how can I fix the ’corrupted mp4 file ? I tried the tool here : http://www.jihosoft.com/free-utilities/mp4-video-repair-tool.html

    But I got a virus from ’Digital Video Repair’
