live transcoding

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

1. Tencent video Upload review process:After uploading a video, you need to wait for transcoding and review. The following steps are required for a video to be uploaded and published:1. Upload a video: enter the title, tag, category, and description of the video. You cannot close the upload page before prompting you to upload the video successfully;2. Transcoding: After the upload is complete, the server ne

Recently in using dedecms two times to develop the membership function; everyone knows that DEDECMS encoding is GBK format; So in our project we often need to transcode, in my understanding there are two ways to transcode: first: iconv; second, mb_convert_encoding;Here are the two ways to use the following transcoding methods:IconvIconv ("Utf-8″," GB2312 ", $string); convert $string from utf-8 encoding to GBK formatFirst parameter: The encoding format

[This article is a complex topic of FFMPEG. It will be quite cool to write] [Different transcoding environments may have different code flows] First popularized: Timestamp, DTS (Decoding time stamp), PTS (presention time stamp), CTS (current time stamp ). The timestamp in ffmepg is in microseconds and is related to the timebase variable. It is used as the time benchmark granularity of DTs and PTS, and the value will be large. Among them, the av_resc

The difference between libiconv and glibc is the same article. I prefer iconv function for transcoding, while mb_convert_encoding function for backup. The iconv information in the same article: phpinfo is as follows: Iconv implementation "libiconv" In this way, the iconv transcoding content is complete. The phpinfo information of another machine is as follows: Iconv implementation glibc In this way, the ico
