    <p>Having issues getting audio to encode to webm. Tried many different methods and it just ain't happenin. The commands are printed below before each pass.</p> <p>I have tried moving the audio commands around, trying different bitrates, different audio commands and have tried it on a couple of different files as well that both have audio.</p> <p>Encoding these files to MP4 using x264 causes no problems and works just fine and the audio plays, so it appears to be an issue just with webm. As you can see below, it is a 2-pass encode.</p> <p>Thanks for any help you can provide!</p> <p>Craig</p> <pre><code>Webm LG PASS 1........................... webm_pass1: /usr/bin/ffmpeg -i /home/thedirectory/video613268.mov -codec:v libvpx -quality good -vf 'scale=640:360 [scaled];movie=/home/thedirectory/watermarks/w640X360.png [logo];[scaled][logo] overlay' -cpu-used 0 -b:v 500k -aspect 16:9 -qmin 10 -qmax 42 -maxrate:v 500k -bufsize:v 1000k -r:v 25/1 -force_fps -threads 0 -an -acodec libvorbis -ac 2 -ab 96k -ar 44100 -pass 1 -f webm -y /dev/null ffmpeg version 0.10.2 Copyright (c) 2000-2012 the FFmpeg developers built on Mar 11 2013 14:48:26 with gcc 4.6.2 20111027 (Red Hat 4.6.2-2) configuration: --prefix=/usr --libdir=/usr/lib64 --shlibdir=/usr/lib64 --mandir=/usr/share/man --incdir=/usr/include --disable-avisynth --extra-cflags='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -fPIC' --enable-avfilter --enable-libfaac --enable-libgsm --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libx264 --enable-gpl --enable-nonfree --enable-postproc --enable-pthreads --enable-shared --enable-swscale --enable-vdpau --enable-version3 --enable-x11grab --enable-libvorbis --enable-libvpx libavutil 51. 35.100 / 51. 35.100 libavcodec 53. 61.100 / 53. 61.100 libavformat 53. 32.100 / 53. 32.100 libavdevice 53. 4.100 / 53. 4.100 libavfilter 2. 61.100 / 2. 61.100 libswscale 2. 1.100 / 2. 1.100 libswresample 0. 6.100 / 0. 6.100 libpostproc 52. 0.100 / 52. 0.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '/home/thedirectory/video613268.mov': Metadata: major_brand : qt minor_version : 537199360 compatible_brands: qt creation_time : 2013-02-23 20:04:32 Duration: 00:00:21.02, start: 0.000000, bitrate: 114326 kb/s Stream #0:0(eng): Video: mjpeg (jpeg / 0x6765706A), yuvj422p, 1920x1080 [SAR 72:72 DAR 16:9], 112786 kb/s, 29.97 fps, 29.97 tbr, 2997 tbn, 2997 tbc Metadata: creation_time : 2013-02-23 20:04:32 handler_name : ?Gestionnaire d?alias Apple Stream #0:1(eng): Audio: pcm_s16be (twos / 0x736F7774), 48000 Hz, 2 channels, s16, 1536 kb/s Metadata: creation_time : 2013-02-23 20:04:32 handler_name : ?Gestionnaire d?alias Apple Incompatible pixel format 'yuvj422p' for codec 'libvpx', auto-selecting format 'yuv420p' [buffer @ 0x1f675a0] w:1920 h:1080 pixfmt:yuvj422p tb:1/1000000 sar:1/1 sws_param: [movie @ 0x1f799c0] seek_point:0 format_name:(null) file_name:/home/thedirectory/watermarks/w640X360.png stream_index:0 [overlay @ 0x1f7c2c0] auto-inserting filter 'auto-inserted scale 0' between the filter 'Parsed_movie_1' and the filter 'Parsed_overlay_2' [scale @ 0x1f78d40] w:1920 h:1080 fmt:yuvj422p -&gt;

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.
