Fix transcript handling issue in youtube-trend-analysis #164
Conversation
WalkthroughThe changes update the YouTube trend analysis workflow to process and validate video transcripts after scraping, saving valid transcripts as text files and excluding erroneous ones. The analysis now uses merged transcript contents instead of file paths. Additional improvements include UTF-8 decoding for subprocess output and updated configuration text to reflect the new content-based processing. Changes

5-5: Remove trailing spaces for consistency.The configuration changes correctly update the parameter references from
{file_paths}to{file_contents}, which aligns with the implementation. However, there are trailing spaces on these lines that should be removed.Apply this diff to remove trailing spaces:
- Analyze the transcripts of several videos using {file_contents}. + Analyze the transcripts of several videos using {file_contents}.- Conduct a fine-grained analysis of the transcripts of several videos using {file_contents}. + Conduct a fine-grained analysis of the transcripts of several videos using {file_contents}.Also applies to: 37-37

136-136: Remove redundant directory creation.The
transcriptsdirectory is already created at line 21. This redundant creation inside the loop is unnecessary.- os.makedirs("transcripts", exist_ok=True)

108-110: Good improvements for robustness!The addition of UTF-8 encoding and stdout validation effectively addresses potential decoding issues and prevents errors when parsing empty responses. These changes align well with the PR objectives.
Youtube-trend-analysis/app.py (2)
204-211: Well-implemented file content merging!The implementation correctly reads all transcript files and merges their contents into a single string, which aligns perfectly with the configuration changes. The UTF-8 encoding ensures proper handling of special characters.
129-166: Excellent transcript processing implementation!The transcript processing logic effectively handles both structured (list) and unstructured transcript formats. The cleanup of erroneous transcript files and tracking of error indices ensures data integrity for downstream analysis.

🛠️ Refactor suggestion
Add error handling for file operations.
The file writing operations should include error handling to gracefully handle potential issues like permission errors or encoding problems.
Wrap the file operations in a try-except block:
- with open(file, "w", encoding="utf-8") as f:
- transcript = channel_scrapped_output[0][i].get(
- "formatted_transcript", []
- )
- if isinstance(transcript, list):
- for entry in transcript:
- text = entry.get("text", "")
- start = entry.get("start_time", 0.0)
- end = entry.get("end_time", 0.0)
- line = f"({start:.2f}-{end:.2f}): {text}\n"
- f.write(line)
- else:
- f.write(str(transcript))
- error_files.append(i)
- del st.session_state.all_files[-1]
+ try:
+ with open(file, "w", encoding="utf-8") as f:
+ transcript = channel_scrapped_output[0][i].get(
+ "formatted_transcript", []
+ )
+ if isinstance(transcript, list):
+ for entry in transcript:
+ text = entry.get("text", "")
+ start = entry.get("start_time", 0.0)
+ end = entry.get("end_time", 0.0)
+ line = f"({start:.2f}-{end:.2f}): {text}\n"
+ f.write(line)
+ else:
+ f.write(str(transcript))
+ error_files.append(i)
+ del st.session_state.all_files[-1]
+ except (IOError, OSError) as e:
+ st.error(f"Failed to write transcript for video {youtube_video_id}: {str(e)}")
+ error_files.append(i)
+ if file in st.session_state.all_files:
+ st.session_state.all_files.remove(file)📝 Committable suggestion

In Youtube-trend-analysis/app.py around lines 141 to 155, the file writing
operations lack error handling, which can cause the program to crash on issues
like permission errors or encoding problems. Wrap the entire file open and write
block in a try-except statement to catch exceptions such as IOError or OSError.
In the except block, log or handle the error appropriately to ensure the program
continues running gracefully without abrupt termination.
