FFMPEG Conversion: Ts Files to Mp4 Playback Issue on QuickTime Mac
When converting a large number (990) of Ts files to a single Mp4 video file using FFMPEG, the resulting Mp4 file plays perfectly fine on VLC, but encounters playback issues on QuickTime Mac. This article aims to provide a detailed context of the topic, covering key concepts, and offering solutions to resolve this issue.
Key Concepts
To understand this issue, it is essential to know about Ts files, Mp4 files, FFMPEG, and QuickTime Mac.
- Ts Files: Ts, or Transport Stream, is a container format for video and audio data. Ts files are often used for digital video broadcasting, including satellite and cable television.
- Mp4 Files: Mp4, or MPEG-4 Part 14, is a multimedia container format used to store video, audio, and other data. Mp4 is widely used for distributing video content on the internet and playing on various devices.
- FFMPEG: FFMPEG is a free and open-source software project that produces libraries and programs for handling multimedia data. FFMPEG is commonly used for converting multimedia formats, including Ts to Mp4.
- QuickTime Mac: QuickTime is a multimedia framework developed by Apple for macOS and iOS. QuickTime Mac enables the playback of various multimedia files, including Mp4.
The Issue
The issue arises when converting a large number of Ts files to a single Mp4 file using FFMPEG. While the converted Mp4 file plays perfectly fine on VLC, it encounters playback issues on QuickTime Mac.
Subtitles
Subtitles can be embedded into Mp4 files, and if the Ts files have subtitles, it is essential to ensure they are properly converted and supported by QuickTime Mac.
ffmpeg -i input.ts -c:v copy -c:a copy -c:s mov_text output.mp4
The above FFMPEG command copies the video and audio streams, but converts subtitles to the mov_text format, supported by QuickTime Mac.
Solutions
There are a few solutions to resolve this issue:
- Convert Subtitles: As mentioned above, converting subtitles to mov_text format can resolve the playback issue on QuickTime Mac.
- Install Perian: Perian is a third-party QuickTime component that adds support for various video formats, including Mp4. You can try installing Perian to resolve the playback issue.
- Use a Different Player: If neither of the above solutions works, you can use a different player on Mac, such as VLC, which supports a wider range of multimedia formats.
When converting Ts files to Mp4 using FFMPEG, it is essential to consider the compatibility of the resulting Mp4 file with various players. In this case, the Mp4 file plays perfectly fine on VLC but encounters playback issues on QuickTime Mac. By converting subtitles to mov_text format or installing Perian, you can resolve the playback issue on QuickTime Mac.
