Okay this one might be a bit hard to explain.
Was recording an MPD DASH stream using N_m3u8DL-RE and was not aware that in the first hour of the stream being live it was outputting a garbage 4x64 video stream before sending out 1080p30 video an hour later.
Everytime I try to remux the recorded mp4 and m4a file it keeps reporting itself to be 1 hour and 36 minutes long and at a bitrate of 76mbps when in actuality it is 12 hours long at a bitrate of 9mbps.
The M4A file also reports itself as being "H264" even though it's within an .m4a container.
I believe this might be caused by a corrupted header (if not the header from the different video coming in the first hour) but I'm not sure.
Here is the ffprobe for the video file.
And here is a sample of both the corrupted video/audio files and a healthy recording from the same exact DASH stream.Code:D:\youtubedl>ffprobe "D:\OUTSIDE_LANDS_2025--CHOXUWU\DAY_1\AMAZON_PRIME_STREAM\c enc_2025-08-08_11-35-17.mp4" ffprobe version N-114833-g5e380bcdb1-20240415 Copyright (c) 2007-2024 the FFmpeg developers built with gcc 13.2.0 (crosstool-NG 1.26.0.65_ecc5e41) configuration: --prefix=/ffbuild/prefix --pkg-config-flags=--static --pkg-conf ig=pkg-config --cross-prefix=x86_64-w64-mingw32- --arch=x86_64 --target-os=mingw 32 --enable-gpl --enable-version3 --disable-debug --disable-w32threads --enable- pthreads --enable-iconv --enable-libxml2 --enable-zlib --enable-libfreetype --en able-libfribidi --enable-gmp --enable-fontconfig --enable-libharfbuzz --enable-l ibvorbis --enable-opencl --disable-libpulse --enable-libvmaf --disable-libxcb -- disable-xlib --enable-amf --enable-libaom --enable-libaribb24 --enable-avisynth --enable-chromaprint --enable-libdav1d --enable-libdavs2 --enable-libdvdread --e nable-libdvdnav --disable-libfdk-aac --enable-ffnvcodec --enable-cuda-llvm --ena ble-frei0r --enable-libgme --enable-libkvazaar --enable-libaribcaption --enable- libass --enable-libbluray --enable-libjxl --enable-libmp3lame --enable-libopus - -enable-librist --enable-libssh --enable-libtheora --enable-libvpx --enable-libw ebp --enable-lv2 --enable-libvpl --enable-openal --enable-libopencore-amrnb --en able-libopencore-amrwb --enable-libopenh264 --enable-libopenjpeg --enable-libope nmpt --enable-librav1e --enable-librubberband --enable-schannel --enable-sdl2 -- enable-libsoxr --enable-libsrt --enable-libsvtav1 --enable-libtwolame --enable-l ibuavs3d --disable-libdrm --enable-vaapi --enable-libvidstab --enable-vulkan --e nable-libshaderc --enable-libplacebo --enable-libx264 --enable-libx265 --enable- libxavs2 --enable-libxvid --enable-libzimg --enable-libzvbi --extra-cflags=-DLIB TWOLAME_STATIC --extra-cxxflags= --extra-libs=-lgomp --extra-ldflags=-pthread -- extra-ldexeflags= --cc=x86_64-w64-mingw32-gcc --cxx=x86_64-w64-mingw32-g++ --ar= x86_64-w64-mingw32-gcc-ar --ranlib=x86_64-w64-mingw32-gcc-ranlib --nm=x86_64-w64 -mingw32-gcc-nm --extra-version=20240415 libavutil 59. 15.100 / 59. 15.100 libavcodec 61. 5.103 / 61. 5.103 libavformat 61. 3.100 / 61. 3.100 libavdevice 61. 2.100 / 61. 2.100 libavfilter 10. 2.101 / 10. 2.101 libswscale 8. 2.100 / 8. 2.100 libswresample 5. 2.100 / 5. 2.100 libpostproc 58. 2.100 / 58. 2.100 [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000004daf40] could not find corresponding trex ( id 1) [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000004daf40] could not find corresponding track id 0 [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000004daf40] trun track id unknown, no tfhd was found [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000004daf40] error reading header D:\OUTSIDE_LANDS_2025--CHOXUWU\DAY_1\AMAZON_PRIME_STREAM\cenc_2025-08-08_11-35-1 7.mp4: Invalid data found when processing input
