How do I set the encode chroma sub-sampling?
by pfraser＠covad.net 08 May '05

08 May '05

I am using FFMpeg for simulation. The input is a series of 1024 x 768 jpegs, and I am making them into an MPEG2 file. I can't work out how to change the chroma sub-sampling between 4:2:0, 4:2:2 and 4:4:4 I use something like: ffmpeg -r 24 -i .\1\jpg\flight_sim%3d.jpg -b 8000 -me zero -y test.mpg but I can't find a command line argument to change the chroma resolution. Thanks

bad decoding of H.264 stream (?)
by wes.shull＠gmail.com 07 May '05

07 May '05

I'm trying to decode the H.264 trailer for Serenity: http://www.apple.com/quicktime/hdgallery/serenity.html (it's a .mov in a 136 MiB .zip; I can put up short excerpts of the .mov if that would be useful to low-bw people) It plays mostly fine (excepting the fact that my Athlon XP 1466 is nowhere fast enough); I get no errors out of mplayer or ffmpeg on it, but I get corruption in the bottom 1/2 of the image, as shown in this screenshot (was playing this time with mplayer -xy .5 to cram it on my puny 1152x864, so the file's res is actually twice as high and wide): http://kuoi.asui.uidaho.edu/~wes/images/serenity-corrupt.jpg The file resolution is ginormous--1920x816--and the corruption is always in the lower part of the image, so I'm wondering if a counter is overflowing somewhere in the decoder. Or does Apple's encoder just suck? What I've tried: * initially was trying using a copy of mplayer built with sources updated from CVS on April 26 (same for libavcodec) * then just now I updated ffmpeg again, to make sure I'm using the absolute latest, and converted the file to mpeg4 with it, to take mplayer out of the H.264 decoding part, even though it's just using libavcodec anyway. Command was "ffmpeg -i serenity_1080p.mov -acodec copy -vcodec mpeg4 -b 16000 ser.avi". No improvement. * Just in case it was mplayer having problems with any video of large dimensions, I then tried scaling it down while converting: "ffmpeg -i serenity_1080p.mov -acodec copy -vcodec mpeg4 -b 16000 -s 480x204 ser-small.avi". Still no joy. I'm running Fedora Rawhide (the devel tree) so there's no guarantee it's not something else on my system. Neither ffmpeg nor mplayer will build with gcc4 (it seems to be stricter with inline asm), so I've been using gcc32. ffmpeg says: "built on Mar 27 2005 20:34:29, gcc: 3.2.3 20030502 (Red Hat Linux 3.2.3-47.fc4)" Anyone else see this problem with this file? Any ideas for other things I should try? --wes

How can I get the raw mpeg4 ES video streams from avi files.
by pkumoonheart＠163.com 07 May '05

07 May '05

hi experts: Can anybody tell me how to split the raw mpeg-4 video stream out from a avi file by ffmpeg. I know I can use "ffmpeg -s cif -i xxx.yuv -s cif -codec mpeg4 xxx.m4v" to generate a m4v file and get the raw mpeg4(ES) video stream. But now ,I have some avi files whose video parts are all mpeg4, I want to get the video parts of them. How can I achieve that .

Hi...

Negative size returned by avcodec_decode_audio
by will＠misconception.org.uk 05 May '05

05 May '05

I'm decoding a fairly standard mpeg-2 stream with avcodec CVS from a couple of weeks ago. This call sometimes returns a negative value for decode_size. e.g. len would be 1688 and decode_size would be -128. The comment for avcodec_decode_audio seems to imply that a negative value here is wrong (i.e. it should be the size of the data or 0, not sure why it's a signed value...) len = avcodec_decode_audio(codec_context, buf, &decode_size, packet->data, packet->size); Can anyone shed any light on this? Thanks,
