• Eorror when try recorder RTSP stream FFMPEG

  31 décembre 2018, par Jefter Rocha

  I am trying to record a stream from my camera using ffmpeg but an error is returned.

  I am using the command :

  ffmpeg -i rtsp://ip_camp:port/user=admin&password=admin&channel=1&stream=0.sdp? -acodec copy -vcodec copy -movflags frag_keyframe+empty_moov -f mp4 C:\backup-cam\test.mp4.

  The error returned :

  [rtsp @ 0000026490509980] method DESCRIBE failed : 451 ERROR
  rtsp ://ip_cam:port/user=admin : Server returned 4XX Client Error, but not one of 400,1,3,4

• How to make only words (not sentences) in SRT file by AssemblyAI

  19 avril 2024, par flip

  Okay... So Im trying to create a video making program thing and I'm basically finished but I wanted to change 1 key thing and don't know how to...
Here's the code :

  


  import assemblyai as aai
import colorama
from colorama import *
import time
import os

aai.settings.api_key = "(cant share)"

print('')
print('')
print(Fore.GREEN + 'Process 3: Creating subtitles...')
print('')
time.sleep(1)
print(Fore.YELLOW + '>> Creating subtitles...')
transcript = aai. Transcriber().transcribe("output/output-tts.mp3")

subtitles = transcript.export_subtitles_srt()
print('>> Created subtitles!')

f = open("subtitles.srt","a")
f.write(subtitles)
print('')
print('Program >> You are going to have to manually run the last python file [addsubtitles.py] because \n this program needs to close to write down the subtitles')
print('')
time.sleep(7)
f.close()


  


  when it exports the SRT it exports it something like this :

  


  1
00:00:00,160 --> 00:00:04,238
Put a finger down if you have ever kissed a

2
00:00:04,286 --> 00:00:05,374
goddamn dog.




  


  but i want it to go word by word but still synced with the time frame in the audio and then generate a srt file that has word by word and no sentences.
How could I do this ? because I have no idea how to implement that into the code.

  


  I tried watching or searching the internet for any ways on doing this because I can't figure it out but there are still no results. Would appreciate if anyone could help.

  


• Need help accessing the key when trying to decrypt .ts files via ffmpeg

  4 juillet 2024, par Diz

  I have downloaded all the individual .ts files and the corresponding m3u8 file from a VOD and I now want to merge them together into a single watchable file.
The problem is, that the .ts files are encrypted and don't understand how to access the key.

  


  Here's the beginning of the m3u8 file :

  


  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:4
#EXT-X-PLAYLIST-TYPE:EVENT
#EXT-X-MEDIA-SEQUENCE:6484
#EXT-X-KEY:METHOD=AES-128,URI="irvine://aes",KEYFORMATVERSIONS="1",IV=0x1E9ABA2B3C916D47D592D9B1E7674F4B
#EXT-X-PROGRAM-DATE-TIME:2024-05-25T07:24:59.682Z
#EXTINF:4.004,
index_1_6484.ts
#EXT-X-PROGRAM-DATE-TIME:2024-05-25T07:25:03.686Z
#EXTINF:4.004,
index_1_6485.ts
#EXT-X-PROGRAM-DATE-TIME:2024-05-25T07:25:07.690Z
#EXTINF:4.004,
index_1_6486.ts
#EXT-X-PROGRAM-DATE-TIME:2024-05-25T07:25:11.694Z
#EXTINF:4.004,
index_1_6487.ts
...



  


  As far as I understood I only have the initialization vector and I need to access the URI to get the actual key.

  


  I have tried to decrypt the playlist with the following command :

  


  ffmpeg -i index_1.m3u8 -c copy output.ts


  


  But I would always get the following errors :

  


  Unable to open key file irvine://aes
Error when loading first segment 'index_1_6484.ts'
Error opening input: Invalid data found when processing input
Error opening input file index_1.m3u8.
Error opening input files: Invalid data found when processing input


  


  I have also tried just decrypting a single .ts file to start with, with similar results.

  


  ffmpeg -decryption_key 1E9ABA2B3C916D47D592D9B1E7674F4B -i index_1_6484.ts -codec copy index_1_6484_out.ts
