Mux将一个常规文件转换成Mpeg TS [英] Mux a regular file into Mpeg TS

问题描述

使用mpeg2-ts和ISDB-T（综合业务数字广播 - Terrestial）的文件广播方式工作，我的问题是我无法将文件放入数据流或rawvideo或在mpeg-ts .... im内使用ffmpeg和avconv。以下是一个测试示例：

ffmpeg -f mpegts -i Myfile.tgz -probesize FILESIZE -mpegts_original_network_id 0x1 -mpegts_transport_stream_id 0x1 -mpegts_service_id 0x25 -mpegts_pmt_start_pid 0xbb9 -mpegts_start_pid 0xbba -metadata service_provider =FILESSERVER-metadata service_name =FILES-muxrate 16M output.ts

解决方案

您可以解释文件作为二进制文本。

  ffmpeg -f bin -i Myfile.tgz -c copy 
 -mpegts_original_network_id 0x1 -mpegts_transport_stream_id 0x1 -mpegts_service_id 0x25 
 -mpegts_pmt_start_pid 0xbb9 -mpegts_start_pid 0xbba 
 -metadata service_provider =FILESSERVER-metadata service_name =FILES
 -muxrate 16M output.ts 
  

然后，提取它

  ffmpeg -i output.ts -c copy -map 0 -f data myfile.tgz 
  

（你可以在第一个命令中得到一个I / O错误消息，但结果是f ine。）

im working in a file broadcasting method using mpeg2-ts and ISDB-T ( Integrated Services Digital Broadcasting - Terrestial), My problem is that im not being able to to put a file into the data stream, or as rawvideo, or anithing inside the mpeg-ts.... im using ffmpeg and avconv. Here is an example of a test:

ffmpeg -f mpegts -i Myfile.tgz -probesize FILESIZE -mpegts_original_network_id 0x1 -mpegts_transport_stream_id 0x1 -mpegts_service_id 0x25 -mpegts_pmt_start_pid 0xbb9 -mpegts_start_pid 0xbba -metadata service_provider="FILESSERVER" -metadata service_name="FILES" -muxrate 16M output.ts

解决方案

You can interpret the file as a binary text.

ffmpeg -f bin -i Myfile.tgz -c copy
-mpegts_original_network_id 0x1 -mpegts_transport_stream_id 0x1 -mpegts_service_id 0x25
-mpegts_pmt_start_pid 0xbb9 -mpegts_start_pid 0xbba
-metadata service_provider="FILESSERVER" -metadata service_name="FILES"
-muxrate 16M output.ts

Then, to extract it

ffmpeg -i output.ts -c copy -map 0 -f data myfile.tgz

(You may get an I/O error message in the first command. But the result was fine.)
