(I removed your video data to save space) I hope this answers your question … Reply However if we swap H264 for MP2V (the old MPEG2 video), then the MPEG-2 codec will try to play back the much more advanced h.264 file – but it will not be able to handle this format and fail. We would be able to get away with swapping the two FourCC’s. Both are capable of handling h.264 video coded files. So changing the FourCC does not change the codec, and using a FourCC from another (unrelated) codec may or may not work.įor example (I’m just making this is up to illustrate!), say be have the codec H264 (often referred to as MPEG4) and one called X264 (an opensource MPEG4 codec).
Simply changing the FourCC might work when the FourCC code is being swapped with the FourCC code of another codec – both codecs have to have some level of compatibility though. This could cause certain files to play just fine on your BluRay player, and other not at all. The problem with AVI is that it does not dictate what codec is being used.
So if your FourCC code was “RLE” then you cannot change it it “DIVX” (not that this would make any sense anyway). Please keep in mind that the new FourCC cannot be longer than the old FourCC code. This process will be very fast, even if your AVI files reside on a network share. The button “ Change FourCC” will, for each file in the list, look for the current FourCC you entered and when it finds it, replace it with the new FourCC code.
The “ Fix QNAP Recording” button will automatically fill in the FourCC requirements for those who use this application to fix their Surveillance Station recordings. Also keep in mind that the FourCC code is case sensitive!! You’ll notice that the drop-down already provides a long list of “common” FourCC codes. The next step is to enter your current FourCC and the FourCC you’d like to replace it with. The same filename will be used with “_bak” added before the extension, so example.avi will have example_bak.avi as a backup file. Optionally, you can use “ Make a Backup” to automatically have a backup made of all files in your list. Making a backup before doing so is highly recommended! Please be aware that the original files will be modified. Warning – Original files will be modified!
