Open letter to the European Parliament’s LIBE committee
28 novembre 2019, par Joselyn Khor — UncategorizedAn open letter to the European Parliament’s LIBE committee
In an effort to stem the tide of external control over user privacy, Matomo has rallied with other like-minded companies like Protonmail, NextCloud, Tutanota and Mailfence, to advocate for pro-privacy changes to the European Commission’s “e-evidence” proposal.
Excerpt from the letter :
“The Commission’s e-evidence proposal threatens the competitive advantage European tech businesses have over their American counterparts by undermining the protections we can provide to our customers. It breaks with the long-standing rule that only trusted national judicial authorities can order companies to hand over customer data for criminal investigations. Instead, the Commission’s e-evidence proposal would allow any foreign law enforcement agency from across the EU to force us to hand out customer data without our own authorities doublechecking the foreign order.
“Different from American Big Tech firms, European privacy tech companies lack the resources to verify the legality of each foreign order. Because of the way the e-evidence proposal is phrased, we would not even be able to properly authenticate foreign authorities to ensure that we are not replying to a malicious actor – let alone object to an order if we found it to be unwarranted.”
Matomo Founder, Matthieu Aubry emphasises, “It is time that privacy-minded tech companies work together to defend their users, their businesses, and the values they are founded on. This is why we are supporting Privacy Tech Europe.”

Multiple Dialogue lines of an ASS subtitle file is displayed at the same time on the video file
14 janvier 2024, par Furkan GözükaraI am trying to code an ASS subtitle burner.


Converting given SRT file into ASS subtitle


Let me show examples


Below is given SRT file - generated with Whisper

00:00:00,640 --> 00:00:01,140
American XL <u>Bully</u> Dog

4
00:00:01,140 --> 00:00:01,280
American XL Bully <u>Dog</u>

5
00:00:01,280 --> 00:00:01,520

6
00:00:01,520 --> 00:00:01,640

7
00:00:01,640 --> 00:00:01,800

8
00:00:01,800 --> 00:00:02,220

00:00:04,060 --> 00:00:04,280

Then this above SRT file is converted into the below ASS subtitle

Both when playing the subtitle in any video player or burning into video via FFMPEG, what happens is, multiple Dialogue lines are being displayed at the same time on the screen.


I am doing a lot of research regarding this but still couldn't find out the issue.


Here screenshot of what I mean. So how can I fix this issue ? What is wrong with my ASS file format ?




Here below the functio that I am use to generate that ASS format


def convert_srt_to_ass(srt_content):
 # ASS header

 )

 ass_content = ass_header
 # Adjust regex to properly capture subtitle number, start time, end time, and text
 matches = list(re.finditer(r'(\d+)\n(\d{2}:\d{2}:\d{2},\d{3}) --> (\d{2}:\d{2}:\d{2},\d{3})\n(.+?)\n\n', srt_content, re.DOTALL))

 prev_end = None
 
 for match in matches:
 start, end, text = match.group(2), match.group(3), match.group(4)
 start = start.replace(',', '.')
 end = end.replace(',', '.')

 # Calculate the correct start and end times to ensure no overlap
 if prev_end and start <= prev_end:
 # Adjust the previous end time to be a bit before the current start time
 prev_end_time = datetime.strptime(prev_end, '%H:%M:%S.%f')
 adjusted_end_time = prev_end_time - timedelta(milliseconds=100) # Adjust by 100 milliseconds
 prev_end = adjusted_end_time.strftime('%H:%M:%S.%f')[:-3] # Truncate to 3 decimal places

 ass_content = ass_content.rstrip()
 ass_content = re.sub(r'(\d{2}:\d{2}:\d{2}\.\d{3}),Default,,$', f'{prev_end},Default,,', ass_content, 1)
 ass_content += '\n'

 prev_end = end

 # Formatting the text and adding it to the content
 text = text.replace('<u>', '{\\c&H00FF00&}').replace('</u>', '{\\c&HFFFFFF&}')
 text = text.replace('\n', '\\N') # Convert newlines within text for ASS format
 ass_content += f"Dialogue: 0,{start},{end},Default,,0,0,0,,{text}\n"

 
 # Conversion of text and other formatting remains the same

 return ass_content

"ffmpeg has text relocations" error in Android
