当调用该函数时,-22 错误码可能表示创建输出格式上下文失败。 错误码 -22 的含义 -22 错误码对应的常量是AVERROR_UNKNOWN,表示未知错误。这并没有提供太多明确的信息,因此需要结合实际情况来判断具体的错误原因。 解决avformat_alloc_output_context2 -22 错误的方法 在处理 -22 错误时,我们可以尝试以下几个解决方...
此处,本人在av_read_frame,得到AVPacket后,没有直接调用av_interleaved_write_frame写文件,最主要的原因是av_interleaved_write_frame里面会对AVPacket的时间(相对各自的AVStream)进行排序,若视频文件比较大,则可能里面需要分配的空间也越来越大,最终由于内存不足导致崩溃。 故本人将读取的音视频packet和字幕packet分别...
