The video is at https://www.youtube.com/watch?v=zJ7hUvU-d2Q, I think the problem may have to do with the large size of the .m4v file (6 550 033 422 bytes on the "Highest available" preferred quality). In any case, download of the .m4v file finishes normally, and so does that of the .m4a file (it seems), but then, as the program creates the 0 bytes .mp4 file and writes something to the HDD, the reported state of the .m4a file changes from "COMPLETED" to "ERROR - Java heap space" and it goes into an endless loop of restarts. https://wordrider.net/forum/10/18291/18291/_subject_#msg-18291 Sun, 05 Apr 2026 19:40:40 +0000 Phorum 5.2.10 https://wordrider.net/forum/10/18291/18353/_subject_#msg-18353 https://wordrider.net/forum/10/18291/18353/_subject_#msg-18353 naaloh FreeRapid Downloader - Plugins Tue, 01 Nov 2016 13:50:08 +0000 https://wordrider.net/forum/10/18291/18302/_subject_#msg-18302 https://wordrider.net/forum/10/18291/18302/_subject_#msg-18302
FRD is a general purpose downloader, IMO it has none or little businesses on media encoding, decoding, merging, etc, as it should be.

Is it really necessary to have the input files to find the bug? Yes.]]> tong2shot FreeRapid Downloader - Plugins Sun, 16 Oct 2016 15:21:50 +0000 https://wordrider.net/forum/10/18291/18300/_subject_#msg-18300 https://wordrider.net/forum/10/18291/18300/_subject_#msg-18300
By the way, is it really necessary to have the input files to find the bug? I mean, although I know next to nothing about Java programming, a "4GB" issue looks like something related to data type limit (32 bit unsigned)...]]> naaloh FreeRapid Downloader - Plugins Sun, 16 Oct 2016 14:50:51 +0000 https://wordrider.net/forum/10/18291/18299/_subject_#msg-18299 https://wordrider.net/forum/10/18291/18299/_subject_#msg-18299 github.com], but I'm not sure.

To download 6GB file will take ~15 hours with my home connection, I'm not sure I'm going to do that to test and find the bug in the library (mp4parser).

I think we probably should stick to the ffmpeg method for large files.

Thanks again, and sorry for the inconvenience.]]> tong2shot FreeRapid Downloader - Plugins Sun, 16 Oct 2016 11:55:48 +0000 https://wordrider.net/forum/10/18291/18298/_subject_#msg-18298 https://wordrider.net/forum/10/18291/18298/_subject_#msg-18298 FreeRapid Downloader was able to combine video and audio into a 6 890 899 025 bytes .mp4 file, but the 5:57:50 hours video stops playing at about 3:42:47 hours, which means (as simple calculation shows) when the player accesses the data beyond 4 gigabytes of the video file, which is surely not a coincidence. Obviously not the player's fault (I tried several), so looks like the mp4parser plugin really can produce corrupt files.

I have not tried combining the files with FFmpeg yet, because I (obviously) lost both .m4v and .m4a and don't feel like re-downloading right now.]]> naaloh FreeRapid Downloader - Plugins Sun, 16 Oct 2016 06:59:54 +0000 https://wordrider.net/forum/10/18291/18297/_subject_#msg-18297 https://wordrider.net/forum/10/18291/18297/_subject_#msg-18297
I was talking about the amount of time to finish the job. For example (with same sample) from here:
- ~2.5 minutes with 512MB heap.
- ~10 minutes with default configuration (160MB heap).
- ~1.5 minutes with ffmpeg/avconv.]]> tong2shot FreeRapid Downloader - Plugins Sat, 15 Oct 2016 16:15:25 +0000 https://wordrider.net/forum/10/18291/18296/_subject_#msg-18296 https://wordrider.net/forum/10/18291/18296/_subject_#msg-18296 naaloh FreeRapid Downloader - Plugins Sat, 15 Oct 2016 15:52:01 +0000 https://wordrider.net/forum/10/18291/18295/_subject_#msg-18295 https://wordrider.net/forum/10/18291/18295/_subject_#msg-18295 here to increase java max heap allocation.

Why will we not fix it? The youtube plugin depends on mp4parser plugin, it is a useful program to handle mp4. There are some limitations with mp4parser. Some were fixed internally by our team, on some problems we use workarounds (you can read the whole conversations about fixes/workarounds here if you are interested). But there are still some problems which cannot be fixed, the heap memory problem is one of them.

The ideal solution IMO is by using external program (ffmpeg, avconv, etc) to do the merging. Not only it's more stable/battle proven, it also performs better than the internal java solution (mp4parser). Also there is no need to reinvent the wheel, even worse when the resulting wheels are square :-) But there are problems with this solution, mainly: distribution.

My personal solution at this moment is by using a (bash) script to (batch) merge the videos with ffmpeg/avconv. Which then can be used/integrated in file manager.]]> tong2shot FreeRapid Downloader - Plugins Sat, 15 Oct 2016 15:39:33 +0000 https://wordrider.net/forum/10/18291/18294/_subject_#msg-18294 https://wordrider.net/forum/10/18291/18294/_subject_#msg-18294 naaloh FreeRapid Downloader - Plugins Sat, 15 Oct 2016 14:51:55 +0000 https://wordrider.net/forum/10/18291/18293/_subject_#msg-18293 https://wordrider.net/forum/10/18291/18293/_subject_#msg-18293 wordrider.net]]]> tong2shot FreeRapid Downloader - Plugins Sat, 15 Oct 2016 14:18:41 +0000 https://wordrider.net/forum/10/18291/18291/_subject_#msg-18291 https://wordrider.net/forum/10/18291/18291/_subject_#msg-18291 https://www.youtube.com/watch?v=zJ7hUvU-d2Q, I think the problem may have to do with the large size of the .m4v file (6 550 033 422 bytes on the "Highest available" preferred quality).
