wstewart 9 Posted June 11, 2022 Share Posted June 11, 2022 in emby 4.6.7, i was able to use ffmpeg from the command line by running /share/CACHEDEV1_DATA/.qpkg/EmbyServer/bin/emby-ffmpeg. now that no longer works with 4.7.2, I get /share/CACHEDEV1_DATA/.qpkg/EmbyServer/bin/emby-ffmpeg: line 17: /share/CACHEDEV1_DATA/.qpkg/EmbyServer/bin/ffmpeg: No such file or directory I would very much like to use the emby ffmpeg in my post.sh script that re-encodes DVR recordings. the reason being is this is the only version of ffmpeg that I have found that has QSV acceleration enabled. Is it still possible to use ffmpeg from command line in emby 4.7.2? Link to comment Share on other sites More sharing options...
Happy2Play 8144 Posted June 11, 2022 Share Posted June 11, 2022 Have you checked the path in the top of a server log? Example from some else's log. /share/CACHEDEV3_DATA/.qpkg/EmbyServer/bin/ffmpeg Link to comment Share on other sites More sharing options...
wstewart 9 Posted June 11, 2022 Author Share Posted June 11, 2022 it is in fact where i expect to be, the the emby log it shows: /share/CACHEDEV1_DATA/.qpkg/EmbyServer/bin/ffmpeg if I try to run /share/CACHEDEV1_DATA/.qpkg/EmbyServer/bin/ffmpeg from ssh shell I get -sh: /share/CACHEDEV1_DATA/.qpkg/EmbyServer/bin/ffmpeg: No such file or directory ffmpeg is in fact in that directory and marked as executable, no idea why it doesn't directly run. I seem to recall from 4.6.7 that I couldn't run ffmpeg directly from shell either. I assumed that emby-ffmpeg was included as a wrapper for emby included ffmpeg. it seems that emby-ffmpeg might not have been updated in the latest version, 4.7.2, by the file date -rwxr-xr-x 1 admin administrators 638 2021-11-17 07:06 emby-ffdetect* -rwxr-xr-x 1 admin administrators 636 2021-11-17 07:06 emby-ffmpeg* -rwxr-xr-x 1 admin administrators 1027 2022-06-03 15:30 emby-server* -rwxr-xr-x 1 admin administrators 100248 2022-06-03 15:30 ffdetect* -rwxr-xr-x 1 admin administrators 894968 2022-06-03 15:30 ffmpeg* -rwxr-xr-x 1 admin administrators 760344 2022-06-03 15:30 ffprobe* as I mentioned, i call emby-ffmpeg from my post.sh script to re-encode my recordings. I would really like to use the emby ffmpeg since it supports qsv acceleration (at least the 4.6.7 version did) Link to comment Share on other sites More sharing options...
alucryd 213 Posted June 12, 2022 Share Posted June 12, 2022 Didn't think anyone used these scripts directly, they live in a different directory in our qnap template so I completely forgot about them. Will be fixed in the next version, in the meantime you can modify your post.sh to cd into the emby directory prior to calling emby-ffmpeg, or add the line in the emby-ffmpeg script directly. Here's what a complete script should look like: #!/bin/sh APP_DIR=$(getcfg EmbyServer Install_Path -f /etc/config/qpkg.conf) NVIDIA_DIR=$(getcfg NVIDIA_GPU_DRV Install_Path -f /etc/config/qpkg.conf) export AMDGPU_IDS="$APP_DIR"/share/libdrm/amdgpu.ids export FONTCONFIG_PATH="$APP_DIR"/etc/fonts export LD_LIBRARY_PATH="$APP_DIR"/lib if [ -n "$NVIDIA_DIR" ]; then export LD_LIBRARY_PATH="$LD_LIBRARY_PATH":"$NVIDIA_DIR"/usr/lib fi export LIBVA_DRIVERS_PATH="$APP_DIR"/lib/dri export OCL_ICD_VENDORS="$APP_DIR"/etc/OpenCL/vendors export PCI_IDS_PATH="$APP_DIR"/share/hwdata/pci.ids export SSL_CERT_FILE="$APP_DIR"/etc/ssl/certs/ca-certificates.crt cd "$APP_DIR" || exit 1 exec "$APP_DIR"/bin/ffdetect "$@" Link to comment Share on other sites More sharing options...
wstewart 9 Posted June 14, 2022 Author Share Posted June 14, 2022 thank you so much, that does seem to work now. did not realize that emby-ffmpeg was actually a script. FYI, the reason I use the emby ffmpeg is that the one included on QNAP is really old, the only other version I found is on qnapclub.eu and it does not have qsv acceleration compiled in. the emby version does and processes at a much higher frame rate. Soon I'll post a how-to on my post script for QNAP that does comskip processing and mpeg2 to h264 conversion, works well with the comskip plugin. i managed to find a compiled version of comskip elsewhere for qnap so that i didn't have to go to the trouble of compiling it.

wstewart 9 Posted June 16, 2022 Author Share Posted June 16, 2022 i have another problem now, ffmpeg with emby 4.7.2 is not working the same as it was with 4.6.3. Files that previously did encode to h264, now throw a segmentation fault with the same options. Newer recordings, instead give [h264_qsv @ 0xe7f600] Error during encoding: device failed (-17) Video encoding failed Conversion failed! I run as follows from my script, with $input and $out output derived from the file with full path specified as a parameter to the script. /share/CACHEDEV1_DATA/.qpkg/EmbyServer/bin/emby-ffmpeg -i "$input" -threads 2 -vf yadif -c:v h264_qsv -global_quality 20 -c:a copy "$out" Any ideas?

Luke 36886 Posted June 16, 2022 Share Posted June 16, 2022 Quote -c:v h264_qsv It might not be as simple as just being able to use that. Look at our hardware transcoding command lines and how they're considerably more complex than this. Link to comment Share on other sites More sharing options...
Luke 36886 Posted June 16, 2022 Share Posted June 16, 2022 Why not just use the conversion feature inside emby server to do the same thing? Link to comment Share on other sites More sharing options...
wstewart 9 Posted June 16, 2022 Author Share Posted June 16, 2022 45 minutes ago, Luke said: Why not just use the conversion feature inside emby server to do the same thing? I have my post recording script setup to first run comskip, then after that run ffmpeg to encode to h264 to reduce size, then move the original recording to another directory for later deletion (haven't taken the time to figure out way to check if ffmpeg succeeded on the encode), then I trigger a library update. I've attached my script for reference, once i get it working i plan a how-to. I didn't see a way to do that with the conversion future in emby. maybe i could do just the h264 conversion with the emby conversion future, is it possible to trigger the conversion feature automatically after a record is completed? ps. if anyone watching this thread wants to use my script, the curl line needs to be customized for your specific setup (library and apikey) post.sh Link to comment Share on other sites More sharing options...
Luke 36886 Posted October 12, 2022 Share Posted October 12, 2022 @wstewart we've got a fix in 4.8.0.11. Can you please try that once it is available for your QNAP and let us know if that resolves the issue for you? Thanks ! Link to comment Share on other sites More sharing options...
wstewart 9 Posted November 6, 2022 Author Share Posted November 6, 2022 (edited) ok will do. just upgraded to 4.7.9, i'll make sure that is stabe for me first, then upgrade to 4.8.0.16 Edited November 6, 2022 by wstewart 1 Link to comment Share on other sites More sharing options...
wstewart 9 Posted November 20, 2022 Author Share Posted November 20, 2022 it has in fact fixed it. my post.sh script now runs after every recording. thanks! but i can't seem to get the built in video conversion to work, it queues the conversion but never runs. I want to check the log for the command line options used for ffmpeg to use the same in my script. Any idea why conversion aren't running? On 4.8.0.16 at moment, will try 4.8.0.19 shortly.

wstewart 9 Posted November 22, 2022 Author Share Posted November 22, 2022 (edited) i am finding that the emby conversion are quite jerky/choppy. the same for encodes using my script that calls the emby ffmpeg with my own/different options. I tried an external media player (Nova) and it is the same, choppy, so I don't think it is emby on the playback side. I'm reviewing some older encodes that I made, I'm not 100% certain, but I don't think they are choppy. when i convert with emby I choose custom and either original quality or set a bit rate. still investigating, but thinking it is either the ffmpeg version or the encode options. i have another version of ffmpeg installed that I'll try. this is on 2017 nvidia shield. I think there was an update not too long ago, so it is not beyond possibility it is shield related and nothing to do with emby or ffmpeg Any ideas?

It's more likely how it's used than the build of ffmpeg itself. We'd have to look at a specific example. Thanks. Link to comment Share on other sites More sharing options...
wstewart 9 Posted November 23, 2022 Author Share Posted November 23, 2022 (edited) my post.sh script is no longer running again. "Recording post-processing script completed with exit code 132" in log. I think this is due to the upgrade to 4.8.0.19, it was working with 4.8.0.16. Is it safe to downgrade to 4.8.0.16? I could at least confirm it is emby and not something else. Edited November 24, 2022 by wstewart Link to comment Share on other sites More sharing options...
