Bug 124357 – banshee makes bad MP4s via faac for ipod transcoding

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Chris Rebert 2006-02-27 22:05:58 UTC]

With banshee v0.10.6, when I sync my library w/ my iPod, it transcodes my flacs to mp4s using faac. However, the files generated are invalid. Neither the iPod, nor faad can play/decode them.
Will post log of banshee's transcoding.

Created attachment 81012 [details]
log of banshee doing transcoding

the references to 160 are referring to the bitrate of 160 that the mp4s are being encoded at. 160 is the default provided by banshee.

[Comment 2 Chris Rebert 2006-03-02 20:39:07 UTC]

confirmed that bug 124457 is unrelated to this bug. transcoding error persists despite remerging world.

[Comment 3 Luis Medinas (RETIRED) 2006-03-04 08:24:22 UTC]

i'll see if there's already any bug reported on gnome bugzilla if not i'll open one for you.

[Comment 4 Luis Medinas (RETIRED) 2006-03-06 11:06:23 UTC]

i commited two versions of banshee 0.10.7 the first with gst 0.8 support only and the other (masked) banshee-0.10.7_p1 with gst 0.10 support only please test both and see if you have the same issue.

[Comment 5 Chris Rebert 2006-03-08 22:49:03 UTC]

with v0.10.7 I get a compile error:

./ImportManager.cs(194,5): error CS0104: `Stat' is an ambiguous reference betwee n `Mono.Unix.Stat' and `Mono.Unix.Native.Stat'

Will try v0.10.7_p1 tomorrow.

[Comment 6 Chris Rebert 2006-03-08 23:56:15 UTC]

with _p1 I get this install error on trying to emerge cdparanoia:

[Comment 7 Luis Medinas (RETIRED) 2006-03-09 05:33:00 UTC]

Open new bugs for those issues. Afaik mp4 via faac is a known bug from upstream and that support is going to be removed soon.
