The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...

How to configure ffmpeg for streaming videos from Red5 into Youtube using youtube-v3-api ?
28 mai 2018, par Alfonso ValdesYou’ll see my problem is next :
Currently I’m working to configure youtube-v3-api for live streaming of .flv videos on my Youtube channel using Red 5 service as stated on next link https://www.red5pro.com/docs/server/ffmpegstreaming.html, this is using next commands for streaming on Linux :
ffmpeg -i rtmp://127.0.0.1:1935/live/streamname live=1 timeout=2 -vcodec libx264 -s 640x480 -vb 500k -acodec libfdk_aac -ab 128k -f flv rtmp://a.rtmp.youtube.com/live2/{Stream name/key}
ffmpeg -rtsp_transport tcp -i rtsp://127.0.0.1:8554/live/streamname -acodec copy -vcodec copy -f flv rtmp://a.rtmp.youtube.com/live2/{Stream name/key}On this, neither RMTP nor RTSP protocols are working for streaming. Also, I have tried several codecs for audio and video configuring different sizes for each one of them, but none of those have worked.
The root streaming videos are generated by an IOS/Android app still on development phase.
The problem comes when no video is displayed on Youtube screen, regardless the video is being sent by Red5 (I confirmed this on my Red5 dedicated server on AWS) and received correctly by Youtube (confirmed by validating on Console), so I have come into a dead end on which I hope you could help me get through.
Any idea of what could be a possible solution ?
Thank you.

ffmpeg mp4 to hls chunks of similar duration
25 mai 2018, par AbhishekI am using below command to convert
mp4
tohls
format usingffmpeg
. Everything is working fine expect for the fact that the output chunk have random duration chunk size.ffmpeg -i ad1.mp4 -strict -2 preset:v veryfast -profile:v baseline -level 3.0 -start_number 0 -hls_list_size 0 -hls_segment_filename 'sample-%06d.ts' -f hls sample.m3u8
I even tried using
-hls_time 10
it somewhat solves my issue, the time is not 10 static. I can totally bear the first and last chunk of different size than specified. Is there any strict way to do that.Sample Output : Link
Output when using -hls_time 10 : Link

I try to get resolution of a video file, and hope this code would help thanks to arionik from GitHub
from subprocess import Popen, PIPE
def getWH(pathvideofile):
in_pipe = Popen(["ffmpeg", "-i", "\"%s\"" % (pathvideofile)], stderr=PIPE)
lines = in_pipe.stderr.readlines()
for line in lines:
rx = re.compile('.+Video.+, (\d{2,4})x(\d{2,4}).+')
m = rx.match(line)
if m is not None:
w = int(m.group(1))
h = int(m.group(2))
return w, hBut get this error code :
m = rx.match(line)
TypeError: cannot use a string pattern on a bytes-like objectWhat it could be ?
Thank you,
