FFMPEG av_interleaved_write_frame():不允许的操作 [英] FFMPEG av_interleaved_write_frame(): Operation not permitted
问题描述
好吧，我在尝试对MOV文件进行编码时收到"av_interleaved_write_frame():不允许操作"错误.首先，我需要概述其背后的条件.
Ok I receiving a 'av_interleaved_write_frame(): Operation not permitted' error while trying to encode an MOV file. Firstly I need to outline the conditions behind it.
我正在通过cron上运行的PHP脚本对12个不同分辨率大小和格式类型的文件进行编码.基本上，它捕获250mb HD MOV文件，并以4种不同的帧大小将其编码为MOV，MP4和WMV文件类型.
I am encoding 12 different files of different resolution sizes and format types via a PHP script that runs on cron. Basically it grabs a 250mb HD MOV file and encodes it in 4 different frame sizes as MOV, MP4 and WMV file types.
现在，脚本需要花费10分钟以上的时间来运行和编码250mb输入文件的每个文件.我正在输出处理时间，并且脚本上的时间达到10分钟时，FFMPEG崩溃，并为正在编码的当前文件和尚未编码的所有其他剩余文件返回"av_interleaved_write_frame():不允许的操作".
Now the script takes over 10mins to run and encode each of the files for the 250mb input file. I am outputting the processing times and as soon as the time on the script hits 10mins FFMPEG crashes and returns "av_interleaved_write_frame(): Operation not permitted" for the current file being encoded and all other remaining files yet to be encoded.
如果输入的视频为150MB，则脚本运行的总时间少于10分钟，因此可以对所有视频进行正确编码.此外，如果我在单个文件上运行FFMPEG命令(对于250mb文件失败)，它将对文件进行编码，不会出现任何问题.
If the input videos is 150MB the total time the script runs for is under 10mins so it encodes all of the videos fine. Additionally if I run the FFMPEG command on the individual file that it fails on for the 250mb file it encodes the file with no issues.
从研究错误"av_interleaved_write_frame()"开始，看来这与我理解为输入文件的时间戳有关.但是，在我的实例中似乎并非如此，因为如果我单独进行处理，则可以毫无问题地对文件进行编码.
From doing to research on the error "av_interleaved_write_frame()" it seems it is related to timestamps of what I understand to be of the input file. But in saying that it doesn't seem to be the case in my instance because I can encode the file with no problem if I do it individually.
示例ffmpeg命令
ffmpeg -i GVowbt3vsrXL.mov -s 1920x1080 -sameq -vf "unsharp" -y GVowbt3vsrXL_4.wmv
10分钟后在失败的文件上输出错误.请记住，如果我自己运行命令，则仅在脚本运行10分钟时运行，该命令就没有问题.
Error output on the failed file at 10mins. Remember there is no issue with the command if I run it by itself it is only when the script hits 10mins.

任何人以前都遇到过此类问题吗?似乎与时间戳有关，但这仅是因为脚本运行的时间超过了10分钟.它可能与PHP/Apache配置有关，但我不知道它是FFMPEG还是我需要查看的服务器配置.
Has any anybody encountered this sort of problem before? It seems to be something to do with the timestamps but only because the script is running for a period longer then 10mins. It maybe related to PHP/Apache config but I don't know if it is FFMPEG or if it is server config I need to be looking at.
推荐答案
此问题的一个简单可解决的原因是(如果您像我一样在搜索此问题时发现了此问题)是在尝试编写分区时文件到已满.确保您有足够的可用空间来写入文件.在linux/unix上，这就像运行
One trivially solvable cause for this problem (if you found this question while searching for this problem, as I did) is when the partition you are trying to write your file to is full. Make sure you have enough available space to write your file to. On linux/unix this is as easy as running
$ df -h
要解决此问题，只需通过将文件移动到另一个分区，删除不需要的文件并清空垃圾桶来释放足够的空间.
To solve, just free up enough space by moving files to another partition, deleting unwanted files, and emptying your trash.
