    <p>I have built ffmpeg for Android using the code and method described at</p> <p><a href="https://github.com/halfninja/android-ffmpeg-x264" rel="nofollow noreferrer">https://github.com/halfninja/android-ffmpeg-x264</a></p> <p>using Ubuntu running in VirtualBox on windows. I then copied libvideokit.so into the Project\libs\armeabi folder of a Windows copy of the provided projects. From there I was able to run the ProjectTest from Eclipse on my Android device. I can see the ffmpeg code being executed but when it gets to the point of opening the input file it gives me the indicated error. I have noticed some discussion of this problem at</p> <p><a href="https://stackoverflow.com/questions/5337833/ffmpeg-on-android-undefined-references-to-libavcodec-functions-although-it-is">FFMpeg on Android, undefined references to libavcodec functions, although it is listed on command line</a></p> <p>but the solutions have not helped since the file protocol is enabled in this build and I also tried putting "file:" in front of the filepath to no avail. For completeness I tried setting minimal_featureset=0 to enable all the defaults but this gives me the same error. Below is a snapshot of the logcat from Eclipse showing the output from Videokit with an extra call to LOGE to display the result from av_open_input_file. Any suggestions of things to try would be greatly appreciated.</p> <pre><code>10-23 11:57:33.888: DEBUG/Videokit(4830): run() called 10-23 11:57:33.888: DEBUG/Videokit(4830): run passing off to main() 10-23 11:57:33.904: DEBUG/Videokit(4830): main(): registering all modules 10-23 11:57:33.927: DEBUG/Videokit(4830): main(): registered everything 10-23 11:57:33.927: DEBUG/Videokit(4830): main(): initting opts 10-23 11:57:33.943: DEBUG/Videokit(4830): main(): initted opts. 10-23 11:57:33.943: ERROR/Videokit(4830): ffmpeg version N-30996-gf925b24, Copyright (c) 2000-2011 the FFmpeg developers 10-23 11:57:33.943: ERROR/Videokit(4830): built on Oct 21 2011 13:54:03 with gcc 4.4.3 10-23 11:57:33.943: ERROR/Videokit(4830): configuration: --enable-cross-compile --arch=arm5te --enable-armv5te --target-os=linux --disable-stripping --prefix=../output --disable-neon --enable-version3 --disable-shared --enable-static --enable-gpl --enable-memalign-hack --cc=arm-linux-androideabi-gcc --ld=arm-linux-androideabi-ld --extra-cflags='-fPIC -DANDROID -D__thumb__ -mthumb -Wfatal-errors -Wno-deprecated' --disable-everything --enable-decoder=mjpeg --enable-demuxer=mjpeg --enable-parser=mjpeg --enable-demuxer=image2 --enable-muxer=mp4 --enable-encoder=libx264 --enable-libx264 --enable-decoder=rawvideo --enable-protocol=file --enable-hwaccels --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --disable-network --enable-filter=buffer --enable-filter=buffersink --disable-demuxer=v4l --disable-demuxer=v4l2 --disable-indev=v4l --disable-indev=v4l2 --extra-cflags='-I../x264 -Ivideokit' --extra-ldflags=-L../x264 10-23 11:57:33.943: DEBUG/Videokit(4830): main(): parsing options 10-23 11:57:33.943: DEBUG/Videokit(4830): parse_options has 4 options to parse 10-23 11:57:33.951: ERROR/Videokit(4830): opt_input_file av_open_input_file /mnt/sdcard/fun/snap0000.jpg -2 10-23 11:57:33.951: ERROR/Videokit(4830): /mnt/sdcard/fun/snap0000.jpg: No such file or directory 10-23 11:57:33.951: ERROR/Videokit(4830): ffmpeg_exit(1) called! </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
