阅读更多关于 Need help transcoding Red5 RTMP stream to MPEG2-TS

问题 Me and my friend are going to make live shows and for that purpose I have set up a Red5 server on my old 2006 Intel Core Duo Mac mini running Mac OS X Snow Leopard Server 10.6.8. I use Flash Media Live Encoder to broadcast to Red5's oflaDemo application and the stream works great, except for the fact that I want the stream to work with iOS. I am developing an app for it, but I still need to convert my stream to Apple's HTTP Live Streaming protocol for it to work. Can anybody help me convert

问题 I'm playing a transport stream file (*.ts) using the following pipeline: gst-launch-0.10 playbin2 uri=file:///c:/bbb.ts But I need to convert that into a pipeline myself. I'm not sure how to achieve this. So far I have tried: (works fine) gst-launch-0.10 -v filesrc location=c:/bbb.ts ! tsdemux ! audio/x-ac3 ! fakesink But if i replace fakesink with autoaudiosink it fails with a not-linked error. And even the fakesink doesn't work for video: gst-launch-0.10 -v filesrc location=c:/bbb.ts !

How to re-multiplex Multiple Program Transport Stream (MPTS) files into a single TS?

阅读更多关于 How to re-multiplex Multiple Program Transport Stream (MPTS) files into a single TS?

问题 I have multiple MPTS files recorded from satellite receivers, I need to cherry pick programs/services/PIDS from each file re-multiplex them into a single MPTS file. Optionally I might be able to get away with taking all the services from every file and adding them to the final MPTS (In case anyone knows about a multiplexer that wouldn't allow me to cherry pick programs) Does anybody know how to do this with open source or free software (like VLC or ffmpeg for example) under either windows or

How are access units aligned within PES packets in Apple's HLS?

阅读更多关于 How are access units aligned within PES packets in Apple's HLS?

问题 Does Apple specify this? How many access units should one put in a PES packet payload? Also, I'm wondering which prefix start codes (if any) are present in PES packets. I assume that the one preceding the first NAL unit within an access unit is useless and mustn't be put. Right? I'd like to know how it's done specifically in HLS - not necessarily any other MPEG-2 TS application. 回答1: I'd like to know how it's done specifically in HLS - not necessarily any other MPEG-2 TS application. HLS is a

How to receive the same udp-stream in several programs?

阅读更多关于 How to receive the same udp-stream in several programs?

问题 I have a closed third party system that sends a unicast UDP stream (MPEG-TS) that I'd like to access in two different programs on the same computer. I can not change anything on the source, not even IP or Port. Is there any other option than to write my own little program that captures the stream and then creates to new streams and resends both? It seems that only one of the two destination programs handles multicast, so I need two unicast streams. 回答1: You should be able to use socat to

Convert H.264 Annex B to MPEG-TS

阅读更多关于 Convert H.264 Annex B to MPEG-TS

SO... I have RAW H.264 video data captured via RTSP in a local file and I am attempting to playback the video in a Java FX application. In order to do this, I need to use Http Live Streaming. I have successfully prototyped a Java FX architecture that can play a video via HLS with a local server using a local folder containing a .m3u8 (HLS index) file and collection of .ts (MPEG-TS) files. The last piece for me is to replace the .ts files with .264 / .h264 files and in the local server, perform the conversion / wrapping of the H.264 Annex B data into MPEG-TS. I am having trouble figuring out

SO... I am trying to take a H264 Annex B byte stream video and encode it into MPEG-TS in pure Java. My goals is to create a minimal MPEG-TS, Single Program, valid stream and to not include any timing information information (PCR, PTS, DTS). I am currently at the point where my generated file can be passed to ffmpeg (ffmpeg -i myVideo.ts) and ffmpeg reports...
