Crash when encoding Nvenc h264 - Lemenus - 26.02.2025 Greetings! - Version 2024.12.21.1 - When trying to convert with Nvenc into h264, conversion fails, while it successful with h265, error simply says that file was not created and "Filter not found for the desired type" - Tried to reset all setting but result is the same Video that I tried to convert is accessible via google drive link: https://drive.google.com/file/d/135TNlNJgp5unnIptOMKIfu6AhIdUPuC_/view?usp=sharing RE: Crash when encoding Nvenc h264 - Selur - 26.02.2025 It's not the encoding that fails, but the muxing.

You can try whether the latest dev works of whether the problem also happens with the dev. Cu Selur RE: Crash when encoding Nvenc h264 - Selur - 26.02.2025 Seems to occur only when h.264 and the time codes are used. When telling Hybrid to ignore the time codes, it works fine. (Telling Hybrid to take the stream and not the container frame rate also seems to work. This will also tell Hybrid to ignore the time codes.) Culprit seems to be either MP4Box or mp4fpsmod. (switched the encoder to x264 and got the same problem) MP4Box has no problem with: "G:\Output\2025-02-26@14_59_13_9910__06_mp4Temp.mp4" (output of the encoding) After adding the time codes with mp4fpsmod: mp4fpsmod -t "G:\Output\timecodeV2_2025-02-26@14_59_13_9910.tc" -x "G:\Output\2025-02-26@14_59_13_9910__06_mp4Temp.mp4" -o "G:\Output\2025-02-26@14_59_13_9910__07_withTimeCodes_0.mp4" Mp4Box reports: F:\Hybrid\64bit>MP4Box.exe -info g:\Output\2025-02-26@14_59_13_9910__07_withTimeCodes_0.mp4 [isom] not enough bytes in box colr: 6 left, reading 7 (file F:/media-autobuild_suite/build/gpac-git/src/isomedia/iff.c, line 226) - try specifying -no-check (might crash) [iso file] Read Box "colr" (start 621) failed (Invalid IsoMedia File) - skipping [iso file] Read Box "avc1" (start 467) failed (Invalid IsoMedia File) - skipping [iso file] Read Box "stsd" (start 451) failed (Invalid IsoMedia File) - skipping [iso file] Read Box "stbl" (start 443) failed (Invalid IsoMedia File) - skipping [iso file] Read Box "minf" (start 379) failed (Invalid IsoMedia File) - skipping [iso file] Read Box "mdia" (start 264) failed (Invalid IsoMedia File) - skipping [iso file] Read Box "trak" (start 164) failed (Invalid IsoMedia File) - skipping [iso file] Read Box "moov" (start 24) failed (Invalid IsoMedia File) - skipping Error opening file g:\Output\2025-02-26@14_59_13_9910__07_withTimeCodes_0.mp4: Invalid IsoMedia File Switching to ffmpeg instead of MP4Box for the muxing also works. (So as a workaround you can enable 'Config->Containers->MP4->FFmpeg instead of MP4Box', before creating the jobs.) Cu Selur Ps.: created an issue entry over at: https://github.com/nu774/mp4fpsmod/issues/36 RE: Crash when encoding Nvenc h264 - Selur - 26.02.2025 Uploaded a new dev version which automatically enforces ffmpeg as mp4 muxer when H.264 + vfr are used. Cu Selur RE: Crash when encoding Nvenc h264 - Selur - 27.02.2025 The mp4fpsmod author fixed the problem. => uploaded a new dev with the updated mp4fpsmod version Cu Selur
