2009-03-24Backporting changes to the transcoder from dahdi.sruffell
- Fix bug where asterisk could not find a loaded transcoder. - Do not allow bad packets to corrupt memory. - Eliminate race condition that could cause asterisk to hang. - General cleanup and whitespace changes. git-svn-id: http://svn.digium.com/svn/zaptel/branches/1.4@4633 5390a7c7-147a-4af0-8ec9-7488f05a26cb
2009-01-07Set that the channel is busy even when it is already built. This is alreadysruffell
done in DAHDI and was an error when back porting. Issue: DAHDI-231 git-svn-id: http://svn.digium.com/svn/zaptel/branches/1.4@4612 5390a7c7-147a-4af0-8ec9-7488f05a26cb
2009-01-05spin_is_lock always evalulates to 0 on SMP kernels. So since I still want tosruffell
keep the check in there to avoid problems in the future (and since this code path is only used when opening a new transcoder session) I made the check conditional on running an SMP kernel. git-svn-id: http://svn.digium.com/svn/zaptel/branches/1.4@4607 5390a7c7-147a-4af0-8ec9-7488f05a26cb
2008-12-04Service the transmit descriptor ring before the receive descriptor ring sosruffell
that commands that are still sitting on the transmit descriptor ring are not completed twice. git-svn-id: http://svn.digium.com/svn/zaptel/branches/1.4@4593 5390a7c7-147a-4af0-8ec9-7488f05a26cb
2008-12-04- Ensure that the sample size is set correctly when decoding G723 packets.sruffell
- Do not use an already built channel if the source and destination formats do not match the formats we want. This fixes a regression introduced by the new transcoder interface where a translation path from one complex codec to another can result in garbled audio. git-svn-id: http://svn.digium.com/svn/zaptel/branches/1.4@4592 5390a7c7-147a-4af0-8ec9-7488f05a26cb
2008-10-10- Ensure that the source format is considered when selecting a transcoder.sruffell
- When a command is to be retried, turn off the TX_COMPLETE flag before resubmitting it to the hardware. This should elimate some of the warnings printed to the kernel log in the wctc4xxp_transmit_cmd function. git-svn-id: http://svn.digium.com/svn/zaptel/branches/1.4@4564 5390a7c7-147a-4af0-8ec9-7488f05a26cb
2008-08-19Couple of fixes for the transcoder:sruffell
- In dahdi_transcode.c, Embed the identifiation number, assigned sequentially when the transcoders are registered, in the transcoder structure. This allows DAHDI_TC_GETINFO to work as expected even though the transcoders are rotated on the list in order to spread the load. - In wctc4xxp, fix bug where all transcoders are named tc400b0. git-svn-id: http://svn.digium.com/svn/zaptel/branches/1.4@4491 5390a7c7-147a-4af0-8ec9-7488f05a26cb
2008-08-14backport new transcoder interface and driver from DAHDIkpfleming

2008-08-12bring back the transcoder interface... it will be upgraded to the new ↵kpfleming
improved version here too git-svn-id: http://svn.digium.com/svn/zaptel/branches/1.4@4477 5390a7c7-147a-4af0-8ec9-7488f05a26cb
2008-08-07remove support for the Digium TC400 transcoder card; the interace to this ↵kpfleming
card has been completely redesigned, and the new interface will only be present in DAHDI; TC400 users will need to upgrade to DAHDI 2.0.0 to continue using their transcoder cards git-svn-id: http://svn.digium.com/svn/zaptel/branches/1.4@4469 5390a7c7-147a-4af0-8ec9-7488f05a26cb
2008-02-18Closes issue #11471. Replaced instances of strncpy with zap_copy_string ↵jpeeler
(added to zaptel.h) to fix any off by one errors and ensure destination string is NULL terminated. git-svn-id: http://svn.digium.com/svn/zaptel/branches/1.4@3846 5390a7c7-147a-4af0-8ec9-7488f05a26cb
