FFmpeg by Example: A Comprehensive Guide for Video and Audio Manipulation
LLM Integration:
hbn highlights a significant shift in how users interact with FFmpeg. Instead of manual searches through Stack Overflow, many now rely on LLMs like ChatGPT to generate commands.simonw showcases the practical application of this trend with the llm cmd tool, demonstrating how LLMs are used multiple times a week for FFmpeg tasks.resonious points out that while LLMs can generate commands, they often produce overly complex or incorrect results, especially for simple tasks like format conversion. This indicates the need for human oversight and correction.Philpax inquires about the specific LLM used by resonious, suggesting that different models (like GPT-4 Turbo or Claude 3.x) may perform better. resonious confirms using GPT-4, and Philpax offers to retest with current models.Over2Chars suggests the development of a triage LLM to optimize query routing, answer quality, and potentially cost. NavinF mentions a company working on a similar concept, focusing on cost optimization by directing queries to appropriate models.jjcm introduces llmpeg, a script simplifying chained commands, further illustrating the integration of LLMs with FFmpeg.nine_k suggests that FFmpeg needs a more expressive language, similar to what jq does for JSON, to improve its usability.Manual Command Crafting and Resources:
jazzyjackson shares a personal project involving scene detection for home video conversion, including links to useful gists.fastily and efortis share their personal FFmpeg cheatsheets, demonstrating how experienced users compile their own resources.greenavocado recommends GStreamer as an alternative with a more sensible command-line interface. legends2k and lehi discuss FFmpeg's filter graph capabilities, while remram raises concerns about GStreamer's maintenance.AdieuToLogic links to an FFmpeg book on GitHub, providing another learning resource.API and Performance Considerations:
merksoftworks expresses a desire for a user-friendly AV1 encoding framework, citing difficulties with FFmpeg's C API. mastax shares positive experiences with GStreamer's API, particularly the Rust bindings.rahimnathwani discusses the use of hardware encoding (-c:v h264_nvenc) for batch processing, noting potential quality trade-offs compared to software encoding. ziml77, icelancer, xnx, and others share their experiences and insights on hardware encoding, highlighting its use cases and limitations.dekhn describes a project using FFmpeg for motion detection in video, detailing the command-line options and Python integration. zahlman provides feedback on the Python code, suggesting improvements based on Pythonic principles.Website Feedback and Alternatives:
ehsankia criticizes the "FFmpeg by Example" website for its lack of organization, highlighted example, and unimplemented features. gariany, the site's creator, responds, explaining the design choices and inviting contributions.xenodium shares a method for saving and reusing FFmpeg commands, highlighting the need for better command management.peter_retief and Narushia discuss issues with a specific command from the website, finding it broken in newer FFmpeg versions.Cloud-Based Solutions and UI:
siscia inquires about interest in a cloud-based FFmpeg solution. nosioptar expresses a lack of interest unless it offers significant speed or cost advantages, while also suggesting that a UI could enhance its appeal. pjc50 notes existing cloud services and discusses pricing models.LocalPCGuy shares a one-liner and method for concatenating multiple video parts into a single MKV file, highlighting the need for clear examples on combining files.Overall Sentiment:
