New submission from johnny <[email protected]>: we have this hardware MPEG encoder here (iMpath-4000) and we were always able to decode streams produced by it with ffmpeg. after upgrading from ffmpeg release 0.5 to ffmpeg release 0.6, the streams were no longer decodeable - only one or two frames per second were decoded (perhaps the I-frames?). of course, the same happens with the current ffmpeg version from "trunk".
i did some regression tests and found out that svn commit 20643 (from 28-11-2009) broke it. so i reverse-applied the 20643 diff to the current version, then ffmpeg crashed on decoding the stream! i then reverse-applied the 20644 diff in addition to the previous one, and then it worked. i still don't understand the logic of the whole thing; why it worked before and why it doesn't work now, and why it works with those two patches reversed. do you want to follow through with this? let me know if you want sample data, i can provide it for you. ---------- assignedto: michaelni messages: 10980 nosy: michaelni priority: normal status: new substatus: new title: unable to decode MPEG-2 stream (iMpath-4000) type: bug ________________________________________________ FFmpeg issue tracker <[email protected]> <https://roundup.ffmpeg.org/issue2047> ________________________________________________
