我们是否需要将 mp4 或 mp3 转码为 HLS 格式以在移动应用上流式传输视频/音频？

Question

We are developing a mobile app which play music and video .

The music (.mp3) and video(.mp4) is about 5 - 20 MB . I knew we must to transcode from .mp4 to HLS format ( .m3u8) for streaming. And I still consider about transcode audio file to HLS format whether or not ?

I have two question.

1. Do we need transcode video (.mp4) to HLS format if the files are about 5- 20 MB.
2. Do we need transcode mp3 file to HLS format if the files are about 5 - 10 MB ?

Answer 1

Do we need transcode video (.mp4) to HLS format if the files are about 5- 20 MB.

No. These are very small. No need to bother with segments, as they won't be a whole lot smaller than the original file anyway. You will have better compatibility with MP4 as-is. Just make sure you use faststart when encoding your MP4 files.

Do we need transcode mp3 file to HLS format if the files are about 5 - 10 MB ?

No. Again, these are small and you have better compatibility for just streaming them as-is.
