Andrew,
Just an update -- gg has been working on the bandicam...mp4 file problem but no solution yet. Maybe looks like a communication error with ffmpeg and cinelerra. I tested with older versions, the furthest back was April 12, 2017 to ensure it was not a new bug and it failed there also. It is a "seek" error and you can see that the ffmpeg "ffplay" program also hangs on this file when doing a seek -- just start ffplay, let it play a little, and then use the "right arrow" key to seek and it will hang.
As my friend told me - this video might be Variable Frame Rate - due to codec not keeping up with full 30 fps capture as various programs did their work. I re-encoded it with ffmpeg, and now it opens ok. ffmpeg -i bandicam\ 2019-08-08\ 00-25-19-503.mp4 -c:v libx264 -c:a copy T.mp4 ffmpeg version 2.8.15 Copyright (c) 2000-2018 the FFmpeg developers built with gcc 5.5.0 (GCC) configuration: --arch=i486 --target-os=linux --prefix=/usr --libdir=/usr/lib --mandir=/usr/man --docdir=/usr/doc/ffmpeg-2.8.15 --enable-gpl --enable-version3 --disable-static --enable-shared --enable-runtime-cpudetect --enable-ffmpeg --enable-ffplay --enable-ffprobe --enable-ffserver --enable-doc --enable-avdevice --enable-avcodec --enable-avformat --enable-avutil --enable-swresample --enable-swscale --enable-postproc --enable-avfilter --enable-avresample --enable-pthreads --enable-bzlib --enable-fontconfig --enable-frei0r --enable-gnutls --enable-iconv --enable-ladspa --enable-libass --enable-libbluray --disable-libbs2b --disable-libcaca --disable-libcelt --enable-libcdio --disable-libdc1394 --disable-libflite --enable-libfreetype --enable-libfribidi --disable-libgme --enable-libgsm --enable-libiec61883 --disable-libilbc --disable-libkvazaar --disable-libmodplug --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --disable-libpulse --disable-libquvi --enable-librtmp --enable-libschroedinger --enable-libsmbclient --enable-libsnappy --disable-libsoxr --enable-libspeex --disable-libssh --enable-libtheora --enable-libtwolame --enable-libv4l2 --enable-libvidstab --enable-libvorbis --enable-libvpx --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxcb --enable-libxvid --enable-libzvbi --enable-lzma --enable-openal --enable-opengl --enable-sdl --enable-x11grab --enable-zlib --disable-debug libavutil 54. 31.100 / 54. 31.100 libavcodec 56. 60.100 / 56. 60.100 libavformat 56. 40.101 / 56. 40.101 libavdevice 56. 4.100 / 56. 4.100 libavfilter 5. 40.101 / 5. 40.101 libavresample 2. 1. 0 / 2. 1. 0 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 2.101 / 1. 2.101 libpostproc 53. 3.100 / 53. 3.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'bandicam 2019-08-08 00-25-19-503.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: mp41 creation_time : 2019-08-07 21:25:19 encoder : BandiMp4Muxer 1.0 encoder-eng : BandiMp4Muxer 1.0 Duration: 01:05:42.43, start: 0.000000, bitrate: 690 kb/s Stream #0:0(eng): Video: h264 (Main) (avc1 / 0x31637661), yuv420p(tv), 1600x1200 [SAR 1:1 DAR 4:3], 682 kb/s, 23.74 fps, 30 tbr, 30k tbn, 60 tbc (default) Metadata: creation_time : 2019-08-07 21:25:19 handler_name : VideoHandler Stream #0:1(eng): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 2 kb/s (default) Metadata: creation_time : 2019-08-07 21:25:19 handler_name : SoundHandler File 'T.mp4' already exists.

Like, few seconds for full width of window) and tried to play file at 2x speed (fast forward) - timeline cursor was not always moving timeline as play progressed - but smaller timeline was moving along ok. Probably 'not enough CPU' problem .... Memory use was around 1.1-1.7Gb. I re-encoded file as 2x faster (1h5min -> 32 min), but then some parts of it started to fly past eyes a bit too fast, so I really need to think what parts need speed up.
Just re-compiled Cin-GG latest, and apparently new filter from ffmpeg 4.2
(I compiled with ffmpeg.git again) was causing segfaults, so I commented it out in /usr/share/cin/ffmpeg/plugin.opts: #freezedetect
Actually, I also commented out derain filter, because it need some other (neural net model?) file I don't have.
ffmpeg 4.2 also was released: http://ffmpeg.org/
Thanks for the notify -- gg will update Cinelerra to start using 4.2 and update plugin.opts -- he did not think it would be available until November or he would not have bothered putting in 4.1.4 already.
Yeah! -- "AV1 decoding support through libdav1d" -- he has been patiently waiting for this as the AOM version currently in as you let us know, is really bad. And one of the distros he does monthly builds on will not even build with it in.
