#6652 closed defect (wontfix)

Flac files don't fast forward/rewind

Description

I think this is related to http://svn.mythtv.org/trac/changeset/19477, which notes some seeking problems. I see oodles of changes that Stuartm has been doing in other areas of the app, so presume he's busy. It's a niggle, no more, but it would be nice to be able to fast forward / rewind these.

When I fast forward or rewind, I get a brief pause on the first key press, then on the second keypress it usually skips to the next track, with a message in the log of: 2009-06-23 06:34:21.951 avfdecoder.o: seek time 7 2009-06-23 06:34:22.267 Error seeking 2009-06-23 06:34:22.267 Read frame failed

Could you see if this problem exists with current trunk - [20829]?

Wow, there's a lot of change in the last two weeks. Presume that's the ffmpeg resync. Retested on 20831 - still doesn't fast forward, but the error messages are different, and it no longer jumps onto the next track:

Does ffplay do any better?

Check suggests that this is an ffmpeg issue, ffplay head has the same problem. Bumping for now.

How does this look following our latest ffmpeg sync? How does current ffplay behave?

comment:9 Changed 10 years ago by paul <at> planar.id.au

Is that the version in 0.23-fixes, or the new 0.24 branch? Unfortunately I "productionised" my test system when I added some tuner cards to it recently, so I only have 0.23-fixes running. I can install another for testing purposes when my new machine turns up end of this week, otherwise I can test 0.23-fixes later tonight (have to upgrade to latest first).

Current ffmpeg trunk can't seek in flac either. I'd suggest that if you want to be able to seek that you build with --enable-libfaad

Until ffmpeg supports seeking in flac we can't do anything about it.
