You need to specify -sn on your command line, to disable the subtitle-part in the source. What you seem to have AFAIK is a MPEG2-TS container, broadcast, with 1 video 1 subtitle 4 audio-streams. ffmpeg AFAIK doesn't know how to handle the subtitle stream. You'll have to explicitedly disable it with the -sn parameter. If you would like to have another audiostream then the first one, you'll have to use the map functions. For video + 2nd audio stream you would need: ffmpeg -i source.mpg copy or encode parameters -map 0:0 -map 0:3 destination.mpg
Thanks for your help. I've continued to play with this, without success. I've specified not only -sn, as you suggest, but also -an as a test to keep the audio streams from interfering. ffmpeg accepts this command line but, unfortunately, it's crashing with an illegal instruction error and generates only an empty output file.

Hey Thomas - I saw the following post: Mac app to resample GH4 8 bit 4:2:0 to 10 bit 4:4:4 - EOSHD Mac app to resample GH4 8 bit 4:2:0 to 10 bit 4:4:4 - EO... Page 1 of 2 - Mac app to resample GH4 8 bit 4:2:0 to 10 bit 4:4:4 - posted in EOSHD: Hey guys, Ive written a really simple command line app for Mac ... View on www.eoshd.com Preview by Yahoo And wonder what math is being used to create 10 bit from 8 bit ;) The result is 2K downsampled or 4K interpolated "There actually is some interesting pixel finagling going on here." And of course the color is still 4:2:0 - or is some non-standard interpolation being used there also? I am using magic lantern hacked 5DMk3 and while 1080P24 see a huge difference in the color compared to any GH 4K on the web. Highlights are always blown out - post converting to 10bit will not rescue the dynamic range clipped during capture. Thanks. BTW a long time back you were trying to help with getting 10bits and / or 4K out of macbookpro17. I could only find a hardware solution. Opened a bug ticket on MAvericks for no 10 bit color support - but it has never even been opened by Apple ;) Cheers, Mike ----------------------------------- mkrjf, not spam impersonating mkrjf On Thursday, March 24, 2011 1:46 AM, belcampo <belcampo@zonnet.nl> wrote: On 03/24/11 01:48, vsethi@iglou.com wrote:
