WMV/ASF plugin fixed crash when load large wmv

[zeas]

Modified the original plugin to fix crash issue when load large wmv/asf files.
Replace all member/local variant refer to offset/filesize to uint64_t

Only win32 now, tested on 2.7.1


The patch above based on official 2.7.1 released source code.

Modified the original plugin to fix crash issue when load large wmv/asf files.

Thanks, I'll try to look into it later. How large were the wmv/asf files to trigger the problem? Did you really encounter WMV > 4 GiB in size?

Yes. And WMV > 2GB may cause crash in previous version (<2.6)
By the way, some large WMV < 4GB may not cause crash but cannot seek frames after a time point, due to pts = read32() * 1000 larger than 0xFFFFFFFF and be truncated.

[eumagga0x2a]

Please try the latest (r181024 or later) nightly (win32, win64). It should fare better when dealing with large wmv files.

The error before using the latest update was that the wmv would not go over 1 hr 11 minutes. Now it does... great.

However now batch processing using py won't work, before it did.

#
# Load all the files in c:\tmp with .avi extension.
# That's it.
#
ext="wmv"
inputFolder="E:\\Silent\\"
#
def convert(filein):   
    if(0 == adm.loadVideo(filein)):
        ui.displayError("oops","cannot load "+filein)
        raise
    # ---------- Inserting project start------------
    adm.videoCodec("HUFFYUV", "encoderType=1")
    adm.audioCodec(0, "PCM");
    adm.setContainer("AVI", "odmlType=1")
    # ---------- Inserting project end------------
    adm.save(filein+".edit.avi") # save the file
    print("Done")
 
#
# Main
#
ui=Gui()
adm = Avidemux()
#
list=get_folder_content(inputFolder,ext)
if(list is None):
    raise
for i in list:
        convert(i)
print("Done")

It say can not find demuxers??

I can still do one file at a time...weird.

It just got stranger. I had the latest version on another directory so i thought to load the old version 2.71. Thus version 2.71 was opened then using the latest version i got batch processing to work. I closed the 2.71 version and batch processing stopped working.

[eumagga0x2a]

First of all, please don't mix Avidemux versions, install only one at a time.

Which build exactly have you downloaded? I didn't have time yet to try any of the new Visual Studio generated builds, I don't know their limitations. Please use MinGW (win64) builds for now, the latest one has been generated on 2018-11-28 so far.

It say can not find demuxers??

Please open the script console in Avidemux and evaluate the following script:

Code Select Expand

ext="wmv"
inputFolder="E:\\Silent\\"
list=get_folder_content(inputFolder,ext)
for i in list:
  print(i)
print("\n")

Does the output lists correctly the content of the folder?

[coolgit]

I got it to work now using fresh install.

The website example http://www.avidemux.org/admWiki/doku.php?id=tinypy:tinypybatch2 shows adm=Avidemux() which doesn't work until i used adm = Avidemux()

Just thought you may like to know.
