New submission from Andrew Wason <[EMAIL PROTECTED]>: ffmpeg, ffplay and mplayer crash while playing or transcoding this video. It is MP4 (H.264/AAC) from a Sanyo HD1000 camera. It plays back OK in QuickTime player but with some visual artifacts.
Sample video uploaded to upload.mplayerhq.hu/MPlayer/incoming/avc-crash/avc-crash.mp4 Will post ffmpeg log in next message since roundup isn't supporting file uploads. Info from gdb when ffmpeg crashes: Error while decoding stream #0.1 [h264 @ 0x1805a00]AVC: Consumed only 149226 bytes instead of 149236 [h264 @ 0x1805a00]negative number of zero coeffs at 66 43 [h264 @ 0x1805a00]error while decoding MB 66 43 [h264 @ 0x1805a00]concealing 143 DC, 143 AC, 143 MV errors Program received signal EXC_BAD_ACCESS, Could not access memory.
