Always can't remember these two functions, simply write down, better turn.Avascript Native API was originally supported, Base64, but due to the limitations of the previous JavaScript, resulting in Base64 basic see useless. When the current HTML5 standard is formalized, BASE64 will have a larger transformation space, which can be implemented for HTML5 APIs such as FileReader API, drag-and-drop uploads, and even canvas,video.Well, before saying a lot, developers need to focus on:Let's take a look

These two functions have their own characteristics, 1, iconv speed, natural preference, but he has a disadvantage, if you encounter the character can not be converted, it is truncated from there. This causes the content in the transcoding to be truncated for no reason. 2, the mb_convert_encoding function is less efficient, but he encounters the content that cannot be converted is not truncated, which preserves the integrity of the content to a great e

This example is modified by Ffempg's doc/example example transcode.c, which can be used to convert audio and video codes as needed. The original example of the role is more similar to the Remux, and did not realize the function of transcoding, only to achieve the format conversion, such as TS to AVI. Can not realize the conversion of audio and video coding format, such as H264 to MPEG2. There are several ways to implement FFmpeg

By default, FreeSWITCH comes with a G729 module that is pass-through-and does not support transcoding. We decided to add a module that supports G729 transcoding to FreeSWITCH. Reference from 8000HZ.First, install the G729 module which supports transcoding1. Download mod_g729.zip (change from Deepwalker-fs_itu_g729-0bcddb5.tar)2. Unzip the #unzip Mod_g729.zip3.
