crosstool-ng | ng fork with the full support

I am converting some old mjpeg videos (stored in .avi container) to h.265 (.mp4 container) but am noticing the colors are smearing. Using the terminal command:

ffmpeg -y -i "input-file.avi" -c:v libx265 -vtag hvc1 "output-file.mp4"

I get the following image (notice how the red and blue are stretched donward). There is a lot of motion in the scene, but the motion is mostly horizontal:

Any idea what might cause this? The detail and resolution seem fine, just the colors are being interpreted weirdly.

Full output:

I'm using python soundfile to audio files in one of my projects. I have a dataset that contains opus files.

python soundfile can not read opus files directly but can read ogg files. (https://github.com/bastibe/python-soundfile/issues/252)

How can I convert all the opus files to ogg files with ffmpeg?

I have tried the following command,

I'm trying to cross-compile C code for my Raspberry Pi 3b+ using crostool-ng. I'm using M1 chip Mac and trying to cross-compile my code in an Ubuntu virtual Machine(Parallels). I compiled my own kernel using buildroot and created a toolchain using crostool-ng. x-tools which is the toolchain I created located at //home/parallels/x-tools and I'm trying to cross-compile a simple code just prints Hello World located at my Desktop. I have tried arm-unknown-linux-gnueabi-gcc -o deneme test.c and got this: deneme: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.3, for GNU/Linux 5.12.12, with debug_info, not stripped file. If I send this to my target rasppi and try to run it with ./deneme I get this error: -sh: ./deneme: not found .I'm sure they are in the same directory. Now, I'm using aarch64 but I tried with armv71 and it didn't work either. Please ask for more information if this is not enough.

Host Machine: Mac m1 chip.

I'm trying to use ffmpeg to prepare a mp4 file which is vertical recorded for upload to youtube. (on a synology DS220+) In the output file I want to have no black bars on the side but blured sodebars of the movie itself. This I'm trying to do whit this code (in the end I want to automate this process, but maybe there is a better way to do this):

I was trying to use crosstool-ng and get it work to build a cross compiler to target a gnu-based linux distros, since alpine comes with musl-libc I guess the cross tool couldn't directly use the type declarations used in gnu's.

More precisely, at the time of installation of the linux headers when building the toolchain, the /usr/include/linux/types.h does not contain some type declarations which errors for:

I'm trying to cross-compile Python 2.7.18 for an x86,uclibc machine using a crosstool-ng example toolchain. The commands used are the following:

python2_top_glibc dir contains a previous Python-2.7.18 installation but for native glibc which was compiled perfectly. libc.so.0 is in fact in the base_rootfs of target system, which is being linked in ./configure stage. I'm stuck at this at the moment. Any clue will be appreciated. Any additional info will be supplied on demand.

Thanks in advance.

I'm creating a mp4 video from jpegs with ffmpeg, using the following command:

ffmpeg -y -threads 0 -f image2 -i jpegs/%05d.jpg -framerate 10 video.mp4

The resulting video will play fine with VLC, but will not play in a Jupyter notebook via:

I am trying to cross-compile Dropbear for an x86 machine where glibc is missing and instead, uclibc is being used. For that aim, I have cross-compiled zlib for this same instruction set using a custom crosstool-ng toolchain and installed it to a custom location.

I'm studying with a Mastering Embedded Linux Programming second edition

can't see the u-boot prompt (U-Boot#)

I used u-boot v2020.07, crosstool-ng v1.24.0 and copied MLO, u-boot.img to sd card.

How can I solve this problem?

thanks.
