When ffmpeg get live stream from specific device as input, it shows a lot of errors and not processing stream correctly: [h264 @ 0x327f3210] missing picture in access unit with size xxx It seems, this is error from libavcodec\h264_parser.c, function parse_nal_units [login to view URL] of these NALs is 6 (H264_NAL_SEI) Problematic behavior can be reproduced in this way using attached file: ffmpeg -i [login to view URL] -vcodec copy -acodec copy -f null /dev/null Need to find the reason, describe it in details with recommended fix steps. Second part of the task will be "make fix for source code of ffmpeg 5.1 and 6.0." as new project or separate milestone in this one.

Hello I am a professional python developer. My main specializations are automation, web scrapers and bots development. I have already developed over 200 scrapers. From the simplest (for example, a competitor's price collector) to complex parsers (with authorization, bypassing captcha, rotating ips and others) which can collect millions of products from amazon. I have done web scrapers for: - Amazon - Instagram - Facebook - Google - Twitter - LinkedIn - Pinterest - Walmart - And many others For scraping I use: - Python - Requests - BeautifulSoup - Selenium - Scrapy - Pyautogui - Undetected Chromedriver - Rotating ips I can bypass: - CloudFlare - IP blocking - Captcha - Authorization required - Other limitations Django / PostgreSQL For big scraping projects I usually use Django with PostgreSQL. This allows us to store information in a database for further processing and use. I also set up an administration area which allows us to check the data and set up scraper configs. If you need a professional solution in this area - I am ready to cooperate. I am ready to make a sample script before we start Regards, Oleg

Hello there! I believe I am the perfect candidate for this project as I have extensive experience with ffmpeg and troubleshooting issues with live streams. After analyzing the error message you provided, it seems that the issue is originating from the libavcodec\h264_parser.c file in the parse_nal_units function. Specifically, the NAL type is 6 (H264_NAL_SEI) which is causing the missing picture error. To fix this issue, I would recommend modifying the parse_nal_units function to properly handle H264_NAL_SEI NAL types. This can be done by adding a new case statement to the switch statement within the function. As for the second part of the task, I can definitely take on the challenge of making a fix for the source code of ffmpeg 5.1 and 6.0. This can be done as a separate milestone within this project or as a new project altogether. Overall, I am confident in my ability to diagnose and fix the issue with ffmpeg and provide expert recommendations for the best course of action. Thank you for considering my bid and I look forward to working with you!
