Transcode segfaults using vid.stab stabilization

[Michiel van Wessem]

Binary package hint: transcode

 vid.stab filters filter_stabilize and filter_transform cause a Segmentation Fault.

This is too bad, because this appears to be the only/only convenient way to stabilize video on Linux.

I'm using 11.04 x86_64.

transcode -J on all my 1-5 minute 720p MP4/AVC/H.264 files stabilize causes a segfault in the standard package (after numerous [filter_stabilize.so] warning: unsupported Codec: 2 ( 9| 0|11) messages.

I tried to rebuild the package from the Ubuntu source. This exposed a bug in gcc when building filter_smartyuv. By eliminating filter_smartyuv, I was able to rebuild.

But to no avail. Same issue.

I also tried rebuilding from the transcode 1.1.5 tarball. This produces a filter_stabilize that does succeed and does not show all the unsupported Codec messages, however the transcode -J transform step produces a segfault.

[Michiel van Wessem (windsunrain)]

Upgrading to GCC 4.6 allowed successful compilation of the entire package, but the segfault on filter_stabilize persists.

[Michiel van Wessem (windsunrain)]

transcode segfault is in quicktime_decode_audio, called from import_mov_decode in import_mov.c, line 426

Audio on my MP4 files is MPEG-4 AAC audio, Stereo, 16kHz, 61 kbps

This segfault is not related to filter_stabilize.so

works for me on 32bit 11.04, transcode 1.1.5, vid.stab 0.75 (downloaded from http://public.hronopik.de/vid.stab/download.php?lang=en)

[Alexey Osipov (lion-simba)]

The "unsupported Codec" problem caused by patch 05_codec_yuv.diff in Ubuntu source deb. When I disable this patch in debian/patches/series, and rebuild the package, stabilizing works fine for me even with vid.stab 0.61.

05_codec_yuv.diff description says that the patch fix a typo CODEC_YUV -> TC_CODEC_YUV420P. My question is: what side effects will appear if we just drop this patch? Is this patch fixing some bug? Anyone have a link, clarifying why this patch is necessary?

You can find fixed version of transcode in my PPA: https://launchpad.net/~lion-simba/+archive/fixes/

There are versions for Lucid and Natty.

When reading the bug-reports, this error seems to occur only on the 64 bit version. When operating on 32 bits, the programme seems to work as normal. I have ubuntu 11.4 64 bits installed, and it occurs for me (unsupported codec).

0.76 BUGFIX in calcFieldTransYUV caused SEGFAULT

Bug seems to be fixed in the upstream.

I have this bug too with oneiric 64-bit.
The files from the link in the comment above does not work (crash) and I can't install package from the PPA neither.

Hi,

thanks for the report.

Could you try to reproduce this with the latest upstream release available in Quantal?

[Expired for transcode (Ubuntu) because there has been no activity for 60 days.]

This is still an issue in trusty.
