Description Pablo Rodríguez 2007-02-04 08:30:24 UTC

Macromedia Flash for Linux plays this files fine.

swfplayer gives the following error message when opening withoutsound.swf:

$ swfplayer withsound.swf 
starting flashparser
decoding...
New block
flashparser done
X Error of failed request:  BadImplementation (server does not implement operation)
  Major opcode of failed request:  129 (MIT-SHM)
  Minor opcode of failed request:  5 (X_ShmCreatePixmap)
  Serial number of failed request:  23
  Current serial number in output stream:  24
init mp3-decoder, size: 31978
X Error of failed request:  BadDrawable (invalid Pixmap or Window parameter)
  Major opcode of failed request:  62 (X_CopyArea)
  Resource id in failed request:  0x3e00005
  Serial number of failed request:  42
  Current serial number in output stream:  45

And segfaults with withoutsound.swf. Here is the backtrace:

(gdb) run withoutsound.swf 
Starting program: /usr/bin/swfplayer withoutsound.swf
Reading symbols from shared object read from target memory...(no debugging symbols found)...done.

#2  0xb7bb275c in __libc_start_main () from /lib/i686/libc.so.6
#3  0x08049261 in ?? ()

Just in case it helps, files were generated with swftools-0.7.0.

Congratulations for your excellent work,


Pablo

flashplayer and libflash are not a part of swfdec.  However, swfdec also chokes on your files.

Comment 4 Benjamin Otte 2007-02-19 12:01:06 UTC

Current git does no longer crash when encountering the files. However, it still doesn't render them correctly.

Comment 5 Pablo Rodríguez 2007-06-19 23:02:32 UTC

I cannot program, but is there any way that I can help to improve swfdec support for swftools generated Flash files?

Comment 6 Stéphane Loeuillet 2007-10-13 04:45:16 UTC

With current git (post 0.5.3) :

withoutsound.swf => displays properly
withsound.swf crashes with the same bug as in bug #12793

Comment 7 Benjamin Otte 2007-10-14 02:47:38 UTC

Indeed, the files work (apart from Stephane's sound crash). I don't know what made them work, but I guess that doesn't matter. ;)
