TI中文支持网在ti8168平台，用DVRRDK_04.01.00.02，对于一些mpeg4的码流格式，硬件解码异常。这些格式我存成码流文件，在ffmpeg下可以正常解码。
rdk的版本为：DVRRDK_04.01.00.02，解码出错打出的消息为：
[m3video] 1365241:WARN
[m3video] DECLINK:ERROR in Declink_mpeg4DecodeFrameBatch.Status[-1]
[m3video] 1365246:DECLINK::links_m3video/iva_dec/decLink_mpeg4.c:[289]::INTERNAL ERROR:-1
[m3video] ALGPROCESS FAILED:STATUS
[m3video] outArgs->viddec3OutArgs.extendedError for channel 0 Error: 0x501400
错误码对应的信息是，没有获取到视频头信息。
对于一些mpeg4，倒是可以解码。就是一部分的mpeg4无法解码。
附件是出错的视频码流，是纯视频码流文件。用ffmpeg的解码命令为： ffplay -i m4v -f in_mp4_err2.mpg4，可以正常解码播放。
这个问题该如何解决？
Chris Meng：
你好，
我使用DVRRDK_04.01.00.02原始代码，可以正常解码你提供的mpeg4码流（700 x 526）。请问你是否对代码做过什么修改？

回复 Chris Meng:
你是怎么解码的，因为这个不是264的，你是怎么读取一帧的码流，再送入解码link的呢？我使用ffmpeg的读取码流再送入的。
multich_xxx里面，对解码的配置代码能贴出了我看看吗？
我的代码为：
//dec for (i=0; i<ipcBitsoutHostPrm.inQueInfo.numCh; i++){if( gVdecModuleContext.vdecConfig.decChannelParams[0].isCodec == VDEC_CHN_H264 ){decPrm.chCreateParams[i].format = 9; //IVIDEO_H264HPdecPrm.chCreateParams[i].profile = 3;//IH264VDEC_PROFILE_ANY}else if( gVdecModuleContext.vdecConfig.decChannelParams[0].isCodec == VDEC_CHN_MPEG4 ){decPrm.chCreateParams[i].format = 6;//IVIDEO_MPEG4ASPdecPrm.chCreateParams[i].profile = 0;}else if( gVdecModuleContext.vdecConfig.decChannelParams[0].isCodec == VDEC_CHN_MPEG2 ){decPrm.chCreateParams[i].format = 4;//IVIDEO_MPEG2HPdecPrm.chCreateParams[i].profile = 0;}else if( gVdecModuleContext.vdecConfig.decChannelParams[0].isCodec == VDEC_CHN_MJPEG ){decPrm.chCreateParams[i].format = 24;//IVIDEO_MJPEGdecPrm.chCreateParams[i].profile = 0;

从文件中读取一帧，是用ffmpeg读取的。

我试了，demo确实可以解码。
问题解决了，不是rdk这边的问题，是ffmepg的获取帧数据的问题。

回复 Siment Lin:
是不是ffmpeg 获取的不是一帧完整的帧数据呢；
