Re: Olympic ceremonies
The first chunk (ffmpeg) came out fine btw. Thanks so much for your time and patience. I'm getting the : av_interleaved_write_frame error on the last chunk now because I didn't really get enough of an overlap. I will do it again but in reading the comment by sebus in your thread Dinky, I tried to get the march build via the link and couldn't find it. I'd be keen to try it just to see if Sebus is right about the windows version, it may perhaps make life a little easier. If anyone knows of where I can obtain the build that deals with wonky timecodes more gracefully can you post the link? ___ get_iplayer mailing list get_iplayer@lists.infradead.org http://lists.infradead.org/mailman/listinfo/get_iplayer
Re: Olympic ceremonies
If you need a windows perspective I'm happy to test if you like. Well I tried the march build and it's the same so I think there's no real point in going any further. I think trimming is the best way forward. The march build which I left in my processing path ended up processing the mp4 with no sound which is interesting. When I switched back it was fine. ___ get_iplayer mailing list get_iplayer@lists.infradead.org http://lists.infradead.org/mailman/listinfo/get_iplayer

Re: Olympic ceremonies
I'm not sure that this is what is happening as I've had several tests terminate in the same way under the 4gb. the closing ceremony terminated at 3.9 and the opening at 4.1 plus I've just deleted one that ended at 2.7 The 4GB limit as I understand is a fat32 limitation not NTFS which is what I am using. Is there any other reason for this limit just in case i've missed something. I got a retry and failure to get a keyframe but I'm not sure of the exact message as I've closed the window.

Re: Olympic ceremonies
Thanks Chris, I just caught up with that issue which I understand now so I'll be trying to split it in chunks as you've suggested. I also realised that my laptop drive is running out of space so that's another factor. Time for a clean up and try again to get the opening and closing ceremonies. Btw. when recording in chunks I'd ideally like to join these up again. Are the streams for HD h264? I'd presumably need something capable of editing these but I'm not sure things like Virtualdub will handle it. Any pointers to a editing path / transcoding path ? regards Louis On 14 August 2012 11:03, Chris Marriott ch...@chrism.demon.co.uk wrote: -Original Message- From: lpc Sent: Tuesday, August 14, 2012 10:15 AM To: get_iplayer@lists.infradead.org Subject: Re: Olympic ceremonies The 4GB limit as I understand is a fat32 limitation not NTFS which is what I am using.

No this is nothing to do with the filesystem, RTMP appears to have a 32-bit value which overflows, see the rtmpdump mailing list for more e.g. http://lists.mplayerhq.hu/pipermail/rtmpdump/2012-August/002060.html ___ get_iplayer mailing list get_iplayer@lists.infradead.org http://lists.infradead.org/mailman/listinfo/get_iplayer

The first chunk is about 2GB and it went straight to the second chunk leaving the first file unfinished for some reason. Not sure what to try next Don't top post. It has made this thread unreadable. When doing this chunking, you should use --attempts=1 to instruct get_iplayer not to retry/resume failed downloads. As Stuart said, retry/resume will almost always fail with --start/--stop. That should allow the first chunk to get re-muxed to MP4 and tagged with metadata. It won't work for succeeding chunks (i.e., those with --start specified), but they can be re-muxed separately. ___ get_iplayer mailing list get_iplayer@lists.infradead.org http://lists.infradead.org/mailman/listinfo/get_iplayer

I think that's because the keyframe distance for this programme is appears to be 4 secs. You got all those warning messages because get_iplayer was making multiple attempts to retry the download, finding the previous file, attempting to resume and failing. With --stop, rtmpdump returns with an error code indicating an incomplete download (because technically it is incomplete), so get_iplayer retries the download. ___ get_iplayer mailing list get_iplayer@lists.infradead.org http://lists.infradead.org/mailman/listinfo/get_iplayer

So if I understand it correctly I need to specify a start - stop duration that is divisible by 4 to get the last keyframe in? Not terribly relevant except for your test case. Keyframe distance will be different for different programmes at different encoding quality. For this case, just round your --stop values to the nearest minute and use --attempts=1. You don't want to bother with retry/resume here. Also how does one re-mux separately. Is that a get_iplayer post function or do I have to reach for some other tools? Use the mailing list archive.
