mythtranscode not working v31 on RPi4

Post by jfabernathy » Fri Apr 03, 2020 5:40 pm

now that I have commercial flagging working and metadata lookup working, I used mythfrontend to check the commercial cuts and move a few around and tried to transcode. My understanding is that will just read the MPEG2 file and remove the commercials. Anyway it failed. My key observation was :
E CoreContext transcode.cpp:243 (TranscodeFile) Not compiled with libmp3lame support

Log below:

Need to add --enable-libmp3lame to ./configure line if building from source. If using packaging/deb-light build system there is a bug see https://code.mythtv.org/trac/ticket/13590

For packaging/deb-light build system, adding to the command line should fix (not tested):

Code: Select all

../../packaging/deb-light/build_package.sh -c "--cpu=cortex-a7 --arch=armv7 --extra-cflags=-mfpu=neon --extra-cxxflags=-mfpu=neon --enable-libmp3lame"

rebuilt with the new options you gave me. My $HOME/.buildrc is

Code: Select all

MYTHTV_CONFIG_OPT_EXTRA="--disable-vdpau --enable-opengl --disable-vaapi --cpu=cortex-a7 --arch=armv7 --extra-cflags=-mfpu=neon --extra-cxxflags=-mfpu=neon --enable-libmp3lame"
Transcode still failed. I also tried to run it from CLI and have a log from that:

Need to add --enable-libmp3lame to ./configure line if building from source. If using packaging/deb-light build system there is a bug see https://code.mythtv.org/trac/ticket/13590

Mike
This has been fixed. Let me know if it is still causing a problem.

As I said it runs with the --enable-libmp3lame configured but transcode is not running correctly. Log attached above.

Peter,

It does not seem to be working on current fixes/31
using default
cd mythtv/mythtv/
../../packaging/deb-light/build_package.sh

results in

+ ./configure --prefix=/usr --disable-vdpau --enable-opengl --disable-vaapi

no --enable-libmp3lame

Code extract packaging/deb-light/fixes/31 config.sh

Code: Select all

        config_opt="--enable-libmp3lame"
        config_opt="$config_opt $MYTHTV_CONFIG_OPT_EXTRA"     <- this is effectively being ignored.
        if [[ `arch` == arm* ]] ; then
            config_opt="$omx_option --disable-vdpau \                      <- I think $omx_option should be $config_opt, there are several places of this use.
              --enable-opengl  \
              --disable-vaapi $MYTHTV_CONFIG_OPT_EXTRA"
        fi

Also I think --cpu=cortex-a7 --arch=armv7 --extra-cflags=-mfpu=neon --extra-cxxflags=-mfpu=neon are also going to be needed, not sure auto detection of neon intrinsic's in ./configure is enough, especially considering which Pi (2, 3 or 4) is used to build (need to make sure compiler always uses same options).

I am currently using:
../../packaging/deb-light/build_package.sh -c "--cpu=cortex-a7 --arch=armv7 --extra-cflags=-mfpu=neon --extra-cxxflags=-mfpu=neon"
for both mythtv.mythtv/ and mythtv/mythplugins/

on a pi 2 build without the extra options (--cpu etc) running readelf -A mythfrontend gives (note arch v6 and no neon)

Code: Select all

Re: mythtranscode not working v31 on RPi4

I'm getting somewhere. I built v31 from source using the following options in .buildrc:

Code: Select all

--disable-vdpau --enable-opengl --disable-vaapi --cpu=cortex-a7 --arch=armv7 --extra-cflags=-mfpu=neon --extra-cxxflags=-mfpu=neon --enable-libmp3lame"
I took a recorded program, that had automatically detect commercials turned on, and edited it using a remote mythfrontend. I loading the detected commercials to the cutlist and saving the cutlist.
Then from the command line I ran:

Code: Select all

mythtranscode --infile 15001_20200404170000.ts --mpeg2 --honorcutlist -o /home/pi/Videos/penguins.ts
It produced a video in mpeg2 format, high quality and missing 20 minutes of commercials. So mythtranscode runs fine on RPi4 from the command line. I just can't get the same results from the Transcode jobs that are a part of the backend setup. But then again I can't make them work on my production v31 x86_64 system either.
