Hi, "mp4 generation" when producing the recordings file fails, relevant lines from log:
process: generate MP4 command: ffmpeg -y -i /opt/open502/webapps/openmeetings/data/streams/1/rec_30_pod_0.mp4 -i /opt/open502/webapps/dars/data/streams/1/rec_30_pod_1.mp4 -i /opt/open502/webapps/openmeetings/data/streams/1/INTERVIEW_30_FINAL_WAVE.wav -filter_complex [0:v][1:v]hstack=inputs=2[v] -map [v] -map 2:a -qmax 1 -qmin 1 -c:v h264 -crf 24 -vsync 0 -pix_fmt yuv420p -vf pad=ceil(iw/2)*2:ceil(ih/2)*2 -preset medium -profile:v baseline -level 3.0 -movflags faststart -c:a aac -ar 48000 -b:a 256k -s 640x260 /opt/open502/webapps/openmeetings/data/streams/hibernate/93067b79-7938-48e1-bab9-fee123dfd55f.mp4 exception: null ... and error msg is: Filtergraph 'pad=ceil(iw/2)*2:ceil(ih/2)*2' was specified through the -vf/-af/-filter option for output stream 0:0, which is fed from a complex filtergraph. -vf/-af/-filter and -filter_complex cannot be used together for the same stream. exitValue: 1 Tried with ffmpeg 4.0 and latest 4.3.1, same error. If I run the same command in the command line and omit the "-vf" options, generation succeeds. Kind regards, Boris
