I don't think anything you might add to configure (including --enable-memalign-hack) will change this invalid read, but I cannot be sure without understanding the problem. Also, what is the point of messing around with the cflags? You don't trust the FFmpeg developers to know which flags works better with their own code? Also, are you _really_ cross-compiling? >>Yes I am cross-compiling - i set the CC env variables to take the compiler >>from my platforms toolchain. The cflags are added to add my options for my platform cpu options , others i may remove but it does not matter for this problem. >> ==19152== Invalid read of size 4 >> ==19152== at 0xFE0A824: decode_frame (get_bits.h:366) >> ==19152== by 0xFE1451B: avcodec_decode_audio3 (utils.c:656) >> ==19152== by 0xFF48F23: av_find_stream_info (utils.c:2045) >> ==19152== Address 0xcb30f02 is 6 bytes after a block of size 364 alloc'd >> ==19152== at 0xFF7953C: malloc (vg_replace_malloc.c:236) >> ==19152== by 0xFD16C83: av_malloc (mem.c:76) >> ==19152== by 0xFD95FB3: av_dup_packet (avpacket.c:81) >> ==19152== by 0xFF4813B: av_find_stream_info (utils.c:2261) >> >> >> will using --enable-memalign-hack help? > > Can you please tell me if this problem happens when decoding any file or > just a particular one?

Can you test if you can reproduce this problem with the ffmpeg binary? This helps a lot to know what is happening. >>I will do the same with ffmpeg( not done yet) binary- I have and come back. But do you have any idea or suggestion what might be going wrong. One thing I should mention here is that this is not a file but a internetradio stream that I am opening .The problem does not happen every time and in some times , say 1/5 case. -Vitor _______________________________________________ libav-user mailing list libav-user@mplayerhq.hu https://lists.mplayerhq.hu/mailman/listinfo/libav-user _______________________________________________ libav-user mailing list libav-user@mplayerhq.hu https://lists.mplayerhq.hu/mailman/listinfo/libav-user
