MD5SUM for patches below: patch here: http://fromani.exit1.org/tc-patches-1.0.x/MD5SUMS
20060313 - various problems with avisync - HIGH references: http://article.gmane.org/gmane.comp.video.transcode.devel/3907 description: avisync delivers very wrong results if used to shift or pad audio track. It also sometimes segfault when closing. See reference(s) message(s) for details and use cases. status: (partly confirmed, need info) I knew those issues are grave, but proper fixing them require a perhaps deep review/rewrite of avilib, that isn't suitable for 1.0.x branch and was not scheduled for 1.1.0. note: affect CVS too.
20060210 - transcode seems to produce incorrect xvid/ac3 avi - MEDIUM references: http://article.gmane.org/gmane.comp.video.transcode.devel/3823 description: quoting above reference: "I use transcode to produce xvid-coded avi's with ac3 sound. With transcode-0.6.14 a rather nasty bug appeared: there is no sound anymore after seeking forward or backward when playing a movie with the Windows Media Player. This happens only if the avi is > 2GB." status: (need info) I need to investigate further to fully understand what's going on, and replicate the issue. Cant't yet esclude a (partially) WMP issue. note: affects HEAD/NMS branches too.
20060122 - segfault when closing an AVI file - HIGH references: http://article.gmane.org/gmane.comp.video.transcode.user/18953 description: transcode, as well as any tool linked to avilib, segfault sometimes when closing a AVI file. This bug seems to emerge mostly when opening in read mode some OpenDML files. Still missing a method to replicate easily this issue. status: (confirmed) Looking for an easy way to trigger the bug note: affects HEAD/NMS branches too.
20060120 - NTSC fps misdetection on some MPEG-PS - MEDIUM references: http://article.gmane.org/gmane.comp.video.transcode.devel/3810 description: tcprobe misdetect NTSC framerate on some sample files. Probing code seems (partly?) broken and deserve at least a review. status: (need info) I would like to get a misdetect sample file in order to do testing/debugging.
20051217 - various issues with filter_subtitler - MEDIUM references: http://article.gmane.org/gmane.comp.video.transcode.user/18628 description: filter_subtitler seems to have multiple issues: lacks of documentation about dependencies, and it seems to not load properly even if succesfully builded status: (need info) I need to investigate further to fully understand what's going on.
experimental solutions, candidates for 1.0.3
20060216 - transcode seems to produce incorrect xvid/pcm avi - MEDIUM references: http://article.gmane.org/gmane.comp.video.transcode.user/19157 http://article.gmane.org/gmane.comp.video.transcode.user/19162 description: when transcoding mjpeg/pcm to xvid/pcm, audio stream seems to be 'too fast'. This was experienced with some windows players. Additionally, using tcprobe on such suspect transcoded files shows that audio bitrate is detected as double as transcode was supposed to encode. (see reference #2) solution: not seems a real transcode problem, this issue was solved using different command line parameters: http://article.gmane.org/gmane.comp.video.transcode.user/19449
20060329 - hangup in Fedora Core 5 using ImageMagick filter modules - HIGH references: http://article.gmane.org/gmane.comp.video.transcode.user/19252 description: Matthias Saou reported that running 'tcmodinfo -i compare' or 'tcmodinfo -i logo' will cause an hangup using vanilla transcode 1.0.2 on Fedora Core 5. solution: for filter_compare, this patch should solve this issue: http://fromani.exit1.org/tc-patches-1.0.x/filter_compare-fixes-try2.patch please note that this patch also solve another issue reported below for filter_logo, this patch should solve this issue: http://fromani.exit1.org/tc-patches-1.0.x/filter_logo-hangup-try1.patch please note that filter_logo included in future 1.1.0 release was significantly rewritten, so this fix isn't suitable for it.
20060216 - bug (probable segfault) when running transcode from another process - HIGH references: http://article.gmane.org/gmane.comp.video.transcode.devel/3829 description: invoking transcode by another program seems to cause a filedescriptor mismatch under some circustances (ex: invoking from httpd, see references). This will lead at least to a crash in tcprobe. status: (confirmed) preliminary fix landed in CVS, but this solution isn't (and it will hardly be) suitable for inclusion in 1.0.x series.
20060130 - export_pcm module sometimes produces empty output file - LOW references: ??? description: export_pcm produces empty output file under certain circustances. Example: audio stereo and outputfile_c.pcm solution: new module (partially rewritten) here: http://fromani.exit1.org/tc-patches-1.0.x/export_pcm.c to install it, backup the vanilla 1.0.2 module, then drop the new one in transcode-1.0.2/export and recompile as usual. please report any problem caused by this module.
20060128 - multiple module parameters using socket interface not working - HIGH references: http://article.gmane.org/gmane.comp.video.transcode.devel/3815 description: quoting above message: "It looks that loading modules with more than one parameter fails." solution: patch here: http://fromani.exit1.org/tc-patches-1.0.x/filter-fix-try2.patch please report any problem caused by this patch.
20060126 - dvraw export module causes segfault whan transcoding dv NTSC -> PAL - HIGH references: http://article.gmane.org/gmane.comp.video.transcode.user/19000 http://article.gmane.org/gmane.comp.video.transcode.user/19021 http://article.gmane.org/gmane.comp.video.transcode.user/19089 http://article.gmane.org/gmane.comp.video.transcode.user/19090 description: Following command line seems to cause a segfault: transcode -i ntsc.dv -c 10-100 -x dv,dv -f 29.97 --export_fps 25 --export_asr 2 \ --import_asr 2 --dv_yuy2_mode -I 5 -Z 720x576 -J modfps --encode_fields b \ -y dvraw,dvraw -o test.dv It seems that 'bufalloc' implementation bundled in export_dvraw module can cause segfault under unclear circumstances. solution: new module (partially rewritten) here: http://fromani.exit1.org/tc-patches-1.0.x/export_dvraw.c to install it, backup the vanilla 1.0.2 module, then drop the new one in transcode-1.0.2/export and recompile as usual. User reported that new module works as expected. please report any problem caused by this module. PLEASE NOTE: I'm still investigating this issue, it can affect other modules too. I'm also thinking about backport 1.1.0-CVS bufalloc/buffree code into 1.0.x.
20060124 - tcmodinfo -i compare causes segfault - HIGH references: ??? description: there is a bug in filter_compare causing tcmodinfo to segfault when used to query module's data. solution: patch here: http://fromani.exit1.org/tc-patches-1.0.x/filter_compare-fixes-try1.patch please report any problem caused by this patch. update 20060330: updated patch avalaible (only style consistency fixes) patch here: http://fromani.exit1.org/tc-patches-1.0.x/filter_compare-fixes-try2.patch
20051119 - tccat segfaults when input is a directory containing multiple VOB files - HIGH references: http://article.gmane.org/gmane.comp.video.transcode.user/18434 http://article.gmane.org/gmane.comp.video.transcode.user/18381 http://article.gmane.org/gmane.comp.video.transcode.user/18446 description: when tccat input is a directory containing multiple VOB files, a sudden segfault can occur with a message like "double free or corruption". This issue can be automatically triggered by some transcode import modules. solution: patch here: http://fromani.exit1.org/tc-patches-1.0.x/tccat-CVS-iodir-backport-try1.patch please report any problem caused by this patch. WARNING this patch can lead to some subtle input corruptions under unclear circumstances. This issue is under investigation.
confirmed (but yet unofficial) solutions, proposed for 1.0.3
20051217 - af6 export module don't load - MEDIUM references: http://article.gmane.org/gmane.comp.video.transcode.user/18630 http://article.gmane.org/gmane.comp.video.transcode.user/18490 description: a problem in transcode (libtc module) prevents af6 module to load correctly, causing dynamic linker to complain. solution: patch here: http://fromani.exit1.org/tc-patches-1.0.x/libtc-c-symbols.patch please report problems if this harm anything.
