Re: [Live-devel] TS file with high VBR

2011-02-01 Thread Christophe Lemoine
Hi Ross, Thanks for spending time on this issue. I understand that this is a major change and it have to be considered carefully. I could not find a good tuning that works with very high VBR TS files. So I end up using CBR files for now. Not only this creates very big files (generating

Hi, I finally managed to encode my H264 videos for streaming (but it is not a very good solution as I need to have a CBR TS file, with about 40% NULL packets.) Tried the new index file: it works perfectly. Thanks a lot Ross for this Just one small detail: when I seek, the stream seems

Hi Ross, Thanks a lot for your answer: that would be great to have better support for high VBR TS file. I get your point regarding streaming of live encoder. Maybe the code could be different depending on the stream source. While testing different muxers, I'm getting confused by some results

[Live-devel] TS file with high VBR

2011-01-10 Thread Christophe Lemoine
Hi, I'm still trying to properly encode a TS file containing H264 video (HD) in order to be able to stream it. The file has a quite high VBR as B and P frames are very often much much smaller than I frames (quite expected with H264). I then get lots of jittering, especially when the image is

Hi Ross, This is really great news. Thanks a lot for your work. Now: I'm trying to stream a TS file containing H.264 video (encoded with x264) and tried many encoding parameters, but cannot get a decent quality (lots of jittering, VLC as a client complains about audio drifts, late frames, ...

[Live-devel] H264 streaming with trick play

2010-11-02 Thread Christophe Lemoine
Hi, I'm looking for a H264 streaming implementation that supports trick play (at least play/pause/skip). Any video container format would be ok to start with. I can see in the list archive that a few developers where doing such an implementation, but could not find any running code I would
