• FFmpeg installation on the server of my web hosting [on hold]

  23 octobre 2017, par Khalid Askia

  On my website I allow users to upload any format of videos but with HTML 5 video tag only mp4 can be played. I have heard about FFmpeg and that it can convert all formats into mp4. But I have no idea on how to install it. I have root access to my server.

  Please help

• FFmpeg does not download hls stream

  26 juillet 2020, par mrlucasrib

  I am trying to download a video from an m3u8 file. I used the chrome dev tools network analyzer and copied the address from the m3u8 file.

  


  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:6
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-PLAYLIST-TYPE:VOD
#EXT-X-KEY:METHOD=AES-128,URI="key://pi1CcgormCfrBeHFonx1SjYyNREActOy9x5fdSmTcQ74q9gDltGOMVTb2KT7jebRYJNU9skhE1wPp3VBgsIQhutzL9nlU7CwifAHVRX63E8abzo+8daPodXlUvN8qlXDKE8I2w37kc+UqyTG86U3Kg==",IV=0x157c77a2bc4ce357dfb893e2c01f8561

#EXTINF:1.0667,
https://contentplayer.website.com/video/4vqnGjj0L3/hls/360/segment-219.ts
#EXT-X-ENDLIST 


  


  So I put in ffmpeg and got a 403 forbidden error

  


  [https @ 0x55c2fae84d80] HTTP error 403 Forbidden
[crypto @ 0x55c2fb11ebc0] Unable to open resource: https://contentplayer.website.com/video/4vqnGjj0L3/hls/540/segment-1.ts
[hls @ 0x55c2fae807c0] Failed to open segment 1 of playlist 0
...


  


  I thought it could be because of some missing http header, so I copied the cURL command from devtools. (I copied from the request of a segment, in which I had the cloudfront authorization key)

  


  I took all the headers from cURL and added them to ffmpeg.

  


  ffmpeg -allowed_extensions ALL -headers 'User-Agent: ...'
-headers 'Accept: */*' 
-headers 'Accept-Language: ...' 
-headers 'Referer: https://player....com/' 
-headers 'Origin: https://player....com' 
-headers 'Connection: keep-alive'
-headers 'Cookie: CloudFront-Policy=..; CloudFront-Signature=...; CloudFront-Key-Pair-Id=..; hotid=..; hmVlcIntegration=..' -headers 'Pragma: no-cache' -headers 'Cache-Control: no-cache' -headers 'TE: Trailers' 
-protocol_whitelist file,crypto,https,tcp,tls -i esse.m3u8  -map 0 -c copy output.mkv  -i link.m3u8  -map 0 -c copy output.mkv


  


  However, I still receive the 403 forbidden error. When I execute the cURL command it downloads the contents of the fragment. My hypothesis was that because it is about HTTP2 the headers were not sent after the first connection, but all the important headers were added.
other ways of doing this process are also welcome

  


• Capture pictures from IP camera

  29 décembre 2016, par Иван Деркач

  i’m trying to make project, which will take picture from ip camera (camera can’t send any esle format of video, except for .h264), my problem in that i don’t know, how to do it. I used live555 library and i tried to use openRTSP (from testProgs). So got images this way, but i had make .mp4 files and save little slices of video, after i opened them with Aforge.Video.FFMPEG library and took pictures, but i couldn’t take the video, while my parallel thread made me those files. So i checked those files in my program, but it doesn’t work. There was another problem, live555 standart program don’t write evenly(first file can be 10 sec, second can be 8 seconds, about 5-6 files don’t work, if total duration 20 secodns), and because of it Aforge couldn’t open them all. Please help me, i suggest that i should use testRTSPclient(from testProgs too), it’s dummy of real program, but i don’t know, what to do, this library little hard for my understanding. Give me advice and thanks.
