View Full Version : QT7 "Error -50: An unknown error has occured" trying to play H.264 file

In encoded a H.264 video with MeGUI and the Anime Extreme quality preset (no, itīs not one of those typical QT compatibility errors ^^), encoded an AAC-HE2 audio track with BeSweet and muxed those with YAMP/MP4Box. The files plays fine in VLC Media Player, but when I try to play the file in Quicktime I get "Fehler -50: Ein unbekannter Fehler ist aufgetreten" -> "Error -50: An unknown error has occured".

I googled a little and found the following post:
To James (comment #27): I got that same error-50 when I forgot to properly set mp4v and mp4a in the drop-down boxes. When I fixed that and reconverted the file, iTunes took the file just fine.

Okay, looks like I set some parameter wrong somewhere. Yamb shows me this movie info:

* Movie Info *

Any idea what to do?

QuickTime isn't able to reproduce the file coz both the audio and the video streams are something it can't understand.
Use a true player (VLC, MPlayer or any DirectShow based player in conjunction with latest FFDShow) coz CrapTime is so crippled it cant be defined a h.264 (and AAC) compliant decoder/player.

I know you're trying to fight the good fight against QuickTime Sharktooth, but it looks like a losing battle on these boards. Seems like we get a new CrapTime question every day, basically reaffirming QT's incompatibility and random bugginess with MPEG-4 AVC Main Profile. We should send a transcript of all the problems people have been having with QT's H.264 to the Apple developers, just to prove to them how bad QuickTime is.

@SenorKaffee: Please post the exact command line you're using for x264 encoding if you have it.

Randall, you are welcome to write such a list ;)

He's using "Anime Extreme" preset... maybe it's AE-BestQuality? (AE stands for Anime Encoding though) that completely incompatible with quicktime...
Well even the quicktime profile that should be compatible with quicktime it is so only for some users...
However here's a raw list of quicktime for win flaws (and that's just for AVC/AAC) :
- Slow as a turtle when it comes to decoding or encoding h.264.
- Incomplete h.264 feature set even for main profile (both decoding and encoding).
- Does not (or has incomplete) support or AAC-HE and AAC+.
- B0rked MP4 parser.
- Screwed brightness.
- Random freezing with multiple sliced h.264 video streams.
- h.264 Encoder produces non standard (maybe even not compliant?) streams.
- MP4 output has custom (useless) info tags.
- Random playback (i mean sometimes they work... sometimes not) of non quicktime generated (but still within the QT decoding capabilities) files.

Maybe there are other bugs but i cant know coz at that point I uninstalled QT7.

Yeah that's why I wanted him to post his x264 command line. We all know QT doesn't do anything "Extreme". heh

Yes, it was AE-BestQuality with a little changes for bitrate and ME range. I wrote that post from work, so I couldnīt look up the right name. ^^


"x264.exe" --bframes 3 --b-pyramid --filter 1,1 --subme 1 --b-rdo --weightb --trellis 2 --analyse none --me dia --merange 32 --progress --no-psnr --output "E:\Bastelkram Auslagerung\1npe06_aemax400.mp4" "E:\Bastelkram Auslagerung\test.avs"

Too bad that Quicktime only pretends to be a H264 player.

Right here where you have --bframes 3 --b-pyramid
I could be wrong, but I think you can only do 2 max B frames. Also you can't do pyramid with QuickTime!!! So try it with...

"x264.exe" --bframes 2 --filter 1,1 --subme 1 --b-rdo --weightb --trellis 2 --analyse none --me dia --merange 32 --progress --no-psnr --output "E:\Bastelkram Auslagerung\1npe06_aemax400.mp4" "E:\Bastelkram Auslagerung\test.avs"

Ans maybe you'll have better luck.
