  • Other interesting software

    13 avril 2011, par

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Android video saves as type "file" instead of video format

    25 novembre 2015, par Marc Rasmussen

    So I have a website where I allow people to upload a video from their phone and send it to their friends.

    Now Iphone works well because it is usually an .mov file. However when I attempt on my android (Samsung galaxy) I get FileType : file

    Howere is an image from my filezilla as to what has been uploaded :

    enter image description here

    The highlighted are the files uploaded from the android device.

    Can anyone tell me why this is happening ? and how I can make sure that it is a video ? and/or convert it into a mp4 format.

  • avutil/aes : Don't use misaligned pointers

    avutil/aes : Don't use misaligned pointers

    The AES code uses av_aes_block, a union consisting of
    
uint64_t[2], uint32_t[4], uint8_t[4][4] and uint8_t[16].
    
subshift() performs byte-wise manipulations of two av_aes_blocks,
    
but when encrypting, it does so with a shift of two bytes ;
    
more precisely, it uses
    
"av_aes_block *s1 = (av_aes_block *) (s0[0].u8 - s)"
    
and lateron uses the uint8_t[16] member to access s0.
    
Yet av_aes_block requires to be suitably aligned for
    
the uint64_t[2] member, which s0[0].u8 - 2 is certainly
    
not. This is in violation of 6.3.2.3 (7) of C11. UBSan
    
reports this in the aes_ctr, mov-3elist-encrypted,
    
mov-frag-encrypted, mov-tenc-only-encrypted and srtp
    
tests.
    
Furthermore, there is another issue here : The pointer points
    
outside of s0 ; this works, because all the accesses lateron
    
use an index >= 3. (Clang-)UBSan reports this as
    
"runtime error : index -2 out of bounds for type 'uint8_t[16]'".
    

    This commit fixes both of these issues : The latter issue
    
is fixed by applying an offset of "+ 3" during the cast
    
and subtracting this from the indices used lateron.
    
The former issue is solved by not casting to av_aes_block*
    
at all ; instead simply cast to unsigned char*.
