In firmware 2.80, I make a folder called "VIDEO" in:ī.) the MP_ROOT directory of the memory stick?Ĭ.) or the PSP directory of the memory stick?Ģ. Every video I create with x264 that is listed correctly in the PSP displays the message "This video cannot be played." when I try to play it.ġ. I have read this entire thread, tried numerous settings on my own, and have finally given up hope of doing this without help. Note that this header is either at the beginning or at the end of the AVC file, and it appears TWICE nearby (I change both). I tried this on some of my previously encoded (x264) AVC videos, as well as a few Google AVC vidoes, and after the changes, they all played in "Video" folder on PSP. What you need to do is search for this hex value and replace them with So for a AVC Main Profile Level 5.1 file (encoded with x264), the "profile-level-id" should be I don't know much about "constraint flags", but it appears to be usually "00". Profile(1 byte):constraint flags(1 byte):level(1 byte) I have finally figured out a way to modify the AVC level so that PSP can recognize it under the "VIDEO" folder :DĪfter some searchings on the Interent, I know that the AVC profile/level information is stored in something called "profile-level-id", a 3-byte header which stores the information in the format of However, I don't know any tool available at the moment to do it. I've read the H.264 standard and it should be possible to do. ) this allows the PSP to use most of the already existing video podcasts. It wouldn't surprise me if the compatibility with videos encoded for the iPod was the main reason Sony implemented these new features.ĮDIT: Just a note explaining why Sony may have implemented these features: by supporting videos encoded for iPod (as well as removing the file name limits and adding video file saving from RSS. You can get both trailers directly from QuickTime website. "A Scanner Darkly" Trailer, 320x172 AVC 24.000fps Video, 44100kHz AAC Audio "Ratatouille" Teaser, 320x132 AVC 23.976fps Video, 44100kHz AAC Audio Here are some examples I've tried to play on my PSP: ) !!! I then simply tried to keep the original. mp4 and simply copied the files on my PSP and they played fine (correct audio/video synchronisation, correct aspect ratio. I've downloaded a few Movie Trailers encoded for the iPod from QuickTime website. This may not look very interesting, but the way I found it is much more interesting: I've done some more testing and I've found another small "hidden" feature: I don't know what happens with files in the old directories. NOTE: I've only tested with files placed in the "VIDEO" directory. Since I haven't spent too much time testing, I may have missed some new things and the removed limits may not work in 100% case. WARNING: These are only my personal findings and if someone could confirm them, it would be good. Files with level set at 1.3, 2 and 2.1 worked. I've tried exactly the same settings (PD-PSP profile from megui) with level set a 1.3, 2, 2.1, 2.2 and Unrestricted. Actually, for the Main Profile, any level set <= 2.1 seems to work. By example, "Main Profile - Level 1.3", "Baseline Profile - Level 2.1" or "Main Profile - Unrestricted Level" didn't work.ĮDIT: I've done some further testing and it seems some cases that didn't work were because of a problem in my x264 settings at the time of the test. I've found that "Main Profile - Level 2.1" and "Baseline Profile - Level 1.3" worked but I haven't had any success with anything else. The PSP seems to do a check on the reported Profile/Level. I've tested with 2 videos (25fps 320x240 with 48kHz sound and 25fps 368x208 with 44kHz sound) and they both worked fine. Atomchanger is not required anymore !! I've been able to create valid files using only megui and avisynth. However, the title of the video that appears on the PSP is now based on the file name and not on the information inside the file anymore and the thumbnail (.thm file) didn't work anymore in the "VIDEO" directory. Videos in the "VIDEO" directory can have any naming you want !!! (no more MAQ*.mp4 naming required !!). (I know, this is part of the official changelog but it's still worth mentioning). Videos can now be placed directly under the "VIDEO" directory of the Memory stick root. I have tested the video support with the updated version and I found the following: I have updated my PSP firmware to 2.80 today (I know, I probably shouldn't have -)).
